vaadin/framework

Vaadin 6, 7, 8 is a Java framework for modern Java web applications.

Vaadin Framework

Vaadin allows you to build modern web apps efficiently in plain Java, without touching low level web technologies.

This repository serves as an archive of the source code and issue tracking for Vaadin 8 and Vaadin 7. Both use GWT as the base of client-side implementations. Vaadin 8 includes Vaadin 7 compatibility classes. You can find source code and issue tracking for newer, web component based Vaadin versions in vaadin/platform.

The code in this repository reflects the state of Vaadin 8.14.3 and Vaadin 7.7.17, the last releases made available under the Apache-2 license, and will be left as-is.

NOTICE

Starting with versions 7.7.30* and 8.15.0, no new code is being released here, as development now happens in a private repository. However, releases are being published as courtesy notifications to the users who have subscribed to the release feed of this repository. The source code attached to Github releases in this repository reflects the state of code in this respository at time of release. It is NOT the source code of the corresponding Extended Maintenance release.

* Note: 7.7.17 is the last Apache-2 licensed version, however in the beginning of the transition phase extended maintenance version changes to the 7.7 branch were being made here. In order to be in compliance with the license terms, you are only allowed to use 7.7 code up to release 7.7.17.

Vaadin Framework has entered extended maintenance

Vaadin Framework 7 and 8 are now being maintained under a closed-source model by the Vaadin Expertise Team. You are free to continue using Vaadin Framework releases up to 8.14.3 and 7.7.17 as made available through this repository, and you are free to fork and maintain the framework yourself.

• Vaadin 8 open source maintenance ended in February 2022, extended support is available until February 2032. Starting with version 8.15.0, Vaadin 8 is subject to commercial Vaadin licenses (CVDLv4 from 8.15.0 onward, VCL-1 from 8.19.0 onward, and VCL-2 starting with 8.21.0). The current license is Vaadin Commercial License, version 2.

Frameset refresh broken in safari (xslt-mode) ?

Originally by @jojule

---

This might not be true anymore. Confirm.

http://bugzilla.millstone.org/show_bug.cgi?id=692

Description: Opened: 2005-05-21 06:55
When multiple windows are being refreshed in a frameset on Safari browser the
refreshed windows are oppened as new windows rather then being refreshed in the
frameset

Reproduce:
Framset Window
-WindowA
-WindowB

User clicks on Window A which cuases it to be reloaded. The action causes the
WindowB to be updated. However, WindowB instead of getting refreshed gets poped
out to a new window.

This issue only happens on Mac OS X Safari Browser. FireFox works fine...

Form setVisibleItemProperties() doesn't work

Originally by @jojule

---

If you try to set any visible item property to Form component the result is a
blank form without any visible field:

public void init() {
Window mainWindow = new Window("Form Window");
setMainWindow(mainWindow);
DataObject msd = new DataObject();
msd.setUserName("ikkieh");
BeanItem bim = new BeanItem(msd);
mainWindow.addComponent(form);
form.setItemDataSource(bim);
form.setVisibleItemProperties(Arrays.asList(new String[]{"userName"}));
}

Client-side tracking and playback of user input events

Originally by @samie

---

For usability point of view a set of components that allow tracking of user inputs and replaying them later. This enables usability experts to perform studies and better understand the user interaction within web applications.

Essential features:

• Server-side API for tracking mouse, keyboard, etc. events
• Component that record/replays user interaction

StringLengthValidator bugs

Originally by @jojule

---

Confirm

http://bugzilla.millstone.org/show_bug.cgi?id=648

Description: Opened: 2003-07-15 21:04
This is from version 3.0.3
If you try to validate a value with StringLengthValidator, and this value
allows null, the validation fails with NullPointerException.
This is because "null allowed" is not handled. I did the correction from
this...

public void validate(Object value) throws Validator.InvalidValueException {
if (value == null && !allowNull)
throw new Validator.InvalidValueException(errorMessage);
// the line below is where the error occurs, because value is null
String s = value.toString();
if (s == null && !allowNull)
throw new Validator.InvalidValueException(errorMessage);
// the line below would cause the same error
int len = s.length();
if ((minLength >= 0 && len < minLength)
|| (maxLength >= 0 && len > maxLength))
throw new Validator.InvalidValueException(errorMessage);
}

to this...

public void validate(Object value) throws Validator.InvalidValueException {
if (value == null && !allowNull)
throw new Validator.InvalidValueException(errorMessage);
String s # (value= null ? null : value.toString());
if (s == null && !allowNull)
throw new Validator.InvalidValueException(errorMessage);
int len # (s= null ? 0 : s.length());
if ((minLength >= 0 && len < minLength)
|| (maxLength >= 0 && len > maxLength))
throw new Validator.InvalidValueException(errorMessage);
}

The same will happen to the isValid() method, as it has the same code.

Hope it helps.

adding a directory theme is interpreted as a jar theme under Linux

Originally by @jojule

---

Confirm this

Is it a duplicate of #140 ?

http://bugzilla.millstone.org/show_bug.cgi?id=656

Trying to add a new theme, I added under my application a directory:

WEB-INF/lib/themes/xul/

In my application I have these lines:

	mainWindow.setTerminal(new WebBrowser());
	mainWindow.setTheme("xul");

I get this exception:

javax.servlet.ServletException: Invalid theme source: /WEB-INF/lib/themes/xul
at org.millstone.webadapter.WebAdapterServlet.getThemeSources(Unknown Source)
at org.millstone.webadapter.WebAdapterServlet.init(Unknown Source)

My guess is that in WebAdapterServlet, the line 414 does not work as expected
under Linux (as /WEB-INF/lib/themes/xul looks indeed like an absolute filename).

Thanks!

Description: Opened: 2005-06-04 22:31
Table can causes ArrayOutOfBundes or NegativeArraySize exceptions if:

1. Create a table which has multiple pages
2. flip to page 2 or higer
3. resize the DataSource to size of a single page

(One would expect the table to automatically flip to valid page)

Method which fail with exceptions or fail silently and later fail at repaint...
setCurrentPageItemID (If passed first itemID the logic never increments index and thus
currentPageIndex is never update)
setCurrentPageIndex (exception thrown)
paintContent (exception thrown)

Grouped Select-components

Originally by [email protected]

Common need is to group 2 or 3 selects so that the first selection changes the contents of the others and so on. It would be nice to have an easy to use common solution for grouping selects or a special group-select-component.

Decide which demos to drop from beta-1

Originally by @jojule

---

Only ship with fully working demos. We'll add more later.

And keep:

• Hello World
• Calculator
• Feature Browser

I would drop (for now, can be added back when finished and polished):

• Large Table
• Chat
• Login
• GO-game

Any other opinions?

Test that demos look decent and work

Originally by Jani Laakso

Evaluate that first feeling from demos is that they work well. Include the following browsers:

• Windows XP IE 6, 7
• Windows XP FF 2 (latest)
• Linux FF 2 (latest)
• Mac FF 2 (latest)
• Mac Safari (latest)

Firefox enforces auto-update, for first release we focus on latest FF version.

rename "autodetected mode" in demo or at least document it

Originally by Jani Laakso

SOA compatible UI architecture

Originally by @samie

---

As mentioned in several sources:

• "Service oriented architecture (SOA) is gaining momentum as an approach to organizing and building enterprise IT infrastructures, and rightly so."
• "SOA markets at $450 million in 2005 are expected to reach $18.4 billion by 2012."

One suggested solution in UI layer integration is mentioned at http://www.looselycoupled.com/opinion/2006/davies-ui-dev0424.html

The core idea here is to introduce the "loose coupling" and "BPEL-style orchestration" into UI layer.

Again, this is something that can be achieved in several different ways and more research on market is needed.

Chat demo is buggy

Originally by @jojule

---

Chat example should be either corrected or removed. Now xslt-mode uses a comet-like implementation and uidl-mode does not work. This is very confusing as toolkit should abstract the differences. Maybe it would be easier to drop this example alltogether?

Here are few issues from bugzilla

http://bugzilla.millstone.org/show_bug.cgi?id=658

Potentially two defects...

1 Mac OS X Safari 1.1 (Panther)
Conversation frame rarely loads. After introducting myself, I hit the "List Chatters"
button to see if I show up. Even when the page completes loading, I don't see
myself (or anyone else). Not even in the source so it's not a rendering bug (but still
could be browser related).

2 Windows Mozilla 1.5
Renders more often than not but I still can't get features to work (same problem as
above).

Can't tell if this is a server load issue (seems sluggish) or if these defects only
happen on the two browsers I use.

Table.getCurrentPageFirstItemId() does not work correctly

Originally by @jojule

---

Please confirm

http://bugzilla.millstone.org/show_bug.cgi?id=639

Description: Opened: 2003-03-19 11:37
The method doesn't use the id variable: it declares it, but doesn't assign any
value (except null).
In certain cases (e.g. when someone direcly manipulates the datasource of the
table) it causes the first (or more) elements to not appear when the table is
rendered.

Original code:
public Object getCurrentPageFirstItemId() {

	// Priorise index over id if indexes are supported
	if (Container.Indexed.class.isAssignableFrom(items.getClass())) {
		int index = getCurrentPageFirstItemIndex();
		Object id = null;
		if (index >= 0 && index < size())
			 ((Container.Indexed) items).getIdByIndex(index);
		if (id != null && !id.equals(currentPageFirstItemId))
			currentPageFirstItemId = id;
	}

	// If there is no item id at all, use the first one
	if (currentPageFirstItemId == null)
		currentPageFirstItemId = ((Container.Ordered) items).firstItemId();

	return currentPageFirstItemId;
}

recommended fix:
public Object getCurrentPageFirstItemId() {

	// Priorise index over id if indexes are supported
	if (Container.Indexed.class.isAssignableFrom(items.getClass())) {
		int index = getCurrentPageFirstItemIndex();
		Object id = null;
		if (index >= 0 && index < size())
			 id = ((Container.Indexed) items).getIdByIndex(index);
		if (id != null && !id.equals(currentPageFirstItemId))
			currentPageFirstItemId = id;
	}

	// If there is no item id at all, use the first one
	if (currentPageFirstItemId == null)
		currentPageFirstItemId = ((Container.Ordered) items).firstItemId();

	return currentPageFirstItemId;
}

Description: Opened: 2006-02-16 21:10
When playing with millstone3.1.0, I build a demo web app and constantly redeploy
to Tomcat 5.5.9 by copying some files to the webapps directory. After some
reloadings, Tomcat throw the following exception though everything is still
working. If I change my Application class to implement java.io.Serializable, I
did not get this exception any more, but, I get a NullPointerException and the
web app won't start any more. I googled net and found NetBeans IDE used to have
similar bug in their IDEJspServlet and they fixed it. That is why I believe it
is the servlet that caused the problem.

There has been problems loading the serialized sessions before, but no earlier
reports about application not starting has been made before this.

Implement Sizeable for table component and better support for ajax implementation

Originally by @mstahv

---

Subtasks:

• implement Sizeable
• add optional variables (as per meeting on fri 26.1.)
• firstrow (first row from which client wants new uidl, not necessary firstvisible, but defaults to this)
• rowsPerRequest (amount of rows client wants to read, defaults to pagelength)

This way client gets by default same data as previously, but can:

• get cache rows as it wants (hinted by sizeable values)
• and update values (firstvisible, selected etc) without receiving pagelength of already rendered rows from server

Batch process/task support or component

Originally by @samie

---

In enterprise applications there is need for batch processes that are run in server. Mostly this means simple tasks that can be run in separate thread. During processing user feedback is needed and and the user should have posssibility continue working with other tasks.

Suggest that simple framework for easily starting and monitoring of separate tasks (threads) is created. Following features seem important:

• Starting separate processing thread in single button click
• Returning the control immediately to user
• Provide the user with feedback about how the processing is going on (see also #111)
• A way to cancel the process and returning the control back to user.

For example Eclipse has generic "task support" that has most of the required features.

Table Components does not forget Selection on new data assign

Originally by @jojule

---

Please confirm (i somehow remember that this should be fixed)

http://bugzilla.millstone.org/show_bug.cgi?id=690

The Table Component does not forget it's selection when a new Container
Datasource is assigned.

Abstract Code:

Container c = ...
myTable.setContainerDataSource(c);

• now the user selects some of the rows

Container c2 = ...
myTable.setContainerDataSource(c2)

Collection selection = (Collection)myTable.getValue();

• now selection also contains IDs of c! It should only contain IDs of c2!

Design drag and drop support API

Originally by @Artur-

---

Generic drag and drop features should be implemented. In certain business applications dnd seems to overperform all other UI methods (for example in design, grouping and organizing tasks).

It should be possible to:

• Drag and drop between components
• Drag and drop within components (e.g. an item in a Tree)

Considerations:

• User can specify a payload for the operation
• Drop target can refuse or accept all payloads or only a specific type of payload
• A drag operation can be move, copy, link, other(?). The interface should visually describe what operation is being performed (cursor).
• Polling of server-side to find out if the current position is a valid target should not be necessary while doing basic dragging operations
  • Advanced drag operations could poll server-side to see if the current target accepts the operation

Millstone backward compatibility

Originally by @samie

---

Toolkit claims to be "backward compatible" with old Millstone 3.1. However, currently update requires code modifications and recompilation of the application. Also the custom themes do not work.

Suggestion was that package called "millstone-compatibility.jar" is created. This eliminates the recompilation needs in most cases. Also at least a small addition in theme Java callback mechanism is required.

Disabling action popups bugs

Originally by @jojule

---

This is an old one, confirm

http://bugzilla.millstone.org/show_bug.cgi?id=624

In ]\default\script\default.js actionPopup
should call not just disableElement/enableElement but
hideElement/showElement also, beacause it looks
confusing. (it's hardly noticeable that the menuitem is
disabled)

Table Sorting does not work if data source implements Container.Ordered, but not Container.Indexed

Originally by Jani Laakso

Please confirm

Description: Opened: 2005-03-16 19:41
Table Sorting does not work if data source implements Container.Ordered, but not Container.Indexed:
The data is sorted, but paging is broken after sorting.

Should we remove all the private static final long serialVersionUID -statements from code?

Originally by @jojule

---

I added them years ago to the codebase because eclipse warned about missing id:s. Does anyone know any reasons why they should be kept in the code?

(or should we just tell eclipse to ignore warnings about them?)
