grid not working with firefox

only filter field and editor is rendered with firefox

How to handle repository events?

I have a project using Spring Data JPA and would like to do something similar to what gs-crud-with-vaadin is doing by using the Repository as a data source for vaadin. However, i have business logic in RepositoryEventListeners (AbstractRepositoryEventListener<> instances), eg, onBeforeSave.

The events in Spring data jpa are fired higher up at the web mvc controller level, so using the repository in vaadin like this example would not cause the events to fire.

Any suggestions on how to deal with this?

run.sh script should use maven wrapper

run.sh shows the following message:

[ERROR]
Downloading: http://repo.maven.apache.org/maven2/org/apache/maven/surefire/surefire-junit-platform/2.22.2/surefire-junit-platform-2.22.2.pom
Return code is: 501 , ReasonPhrase:HTTPS Required

I searched, found and followed the instructions: https://blog.adamgamboa.dev/2020/01/16/maven-central-repository-is-moving-to-https-and-disablig-http-access/

According these instructions I changed pom.xml in both maps (complete and initial) but the above error still occurs.

What is it I am doing wrong?
Thanks

No mention of Spring Initializer on spring.io/guides

Hi, did you omit mentioning Spring Initializer on the official guide of the website on purpose or is it just a mistake ?
https://spring.io/guides/gs/crud-with-vaadin/

Also the guide mentions "Accessing data with JPA" but the link is dead. https://spring.io/gs/accessing-data-jpa

Upgrade to Spring Boot 1.5

Cannot upgrade pending Vaadin's vaadin/spring#170

bean validation

Is there a easy way to get bean validation working on vaadin ?

hibernate class missing

when trying to run the project from the initial folder I'm getting an error about a hibernate class not found

Caused by: java.lang.ClassNotFoundException: org.hibernate.HibernateException
at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_162]

... 67 common frames omitted

the "gemfire" link leads to a 404

The link Accessing Data with GemFire at the bottom of the README leads to a page that does not exist.
Has it changed to "https://spring.io/guides/gs/accessing-gemfire-data-rest" maybe ?

Cannot incorporate into pom.xml

Neither spring initialiser nor direct incorporation into pom.xml in accordance with your example get the module working properly. Is this because I am using Eclipse and not IntelliJ, or is there some other reason?

Cancel button should work differently

gs-crud-with-vaadin/complete/src/main/java/com/example/crudwithvaadin/CustomerEditor.java

Line 68 in fbca979

cancel.addClickListener(e -> editCustomer(customer));

Hi! I made the tutorial and I really like it. I just realized that this line might be wrong here because when I cancel the "edit" operation the Editor should hide again. Therefore it makes sense to push null into the editCustomer function right?

Missing javascript module

Simply running the complete example gives me the following error (using node v16.13.0 which is the current LTS). Not sure what's wrong.

Unable to determine mode of operation

Hi,
the guide doesn't state how to start the project.
I tried:
mvn spring-boot:run (inside the complete directory)
build is successful, but opening localhost:8080 yields the Whitelabel Error Page with this information:

There was an unexpected error (type=Internal Server Error, status=500).
Unable to determine mode of operation. To use npm mode, ensure 'flow-build-info.json' exists on the classpath. With Maven, this is handled by the 'prepare-frontend' goal. To use compatibility mode, add the 'flow-server-compatibility-mode' dependency. If using Vaadin with Spring Boot, instead set the property 'vaadin.compatibilityMode' to 'true' in 'application.properties'.

What am I missing?

Upgrade README to vaadin 8

There is not BeanItemContainer anymore in Vaadin8 so the reference to it should be removed.

Undefined method in Grid setColums()

Next lines can fix it
grid.addColumn("id");
grid.addColumn("firstName");
grid.addColumn("lastName");

Upgrade Spring Boot to the latest version

Update the guide to use the most recent Spring Boot version.

To do so, change the Spring Boot version in:

initial/build.gradle
initial/pom.xml
complete/build.gradle
complete/pom.xml

Requires node and npm to be installed

Title, basically. Just downloaded the complete example and tried to run it. You will get an error from Vaadin (which is a bug in Vaadin; it should be installing it itself, but doesn't). This can be solved by manually installing node and npm, but should be mentioned in the guide.

Could not add lastname? and I think update functionality is missing?

com.vaadin.flow.component cannot be resolved

In MainView.java I am getting the following error when trying to extend VerticalLayout:

The hierarchy of the type MainView is inconsistent.
The type com.vaadin.flow.component.Component cannot be resolved. It is indirectly referenced from required .class files

Help. Is this repo still working?

Hello there. I was trying to find a tool to create a Full CRUD UI quickly and ended up here. I tried to run the complete and initial and hit localhost:8080 and it throws an error

com.vaadin.flow.router.NotFoundException: Couldn't find route for ''
com.vaadin.flow.server.BootstrapException: Unable to read webpack stats file.
java.net.ConnectException: Connection refused: no further information_

In addition, when It loads frontend dependencies It throws many warnings related to deprecated dependencies.

Is this repo still updated?

Application failed to start

The application failed to start:

Description:

Parameter 1 of constructor in org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration required a bean of type 'org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath' in your configuration.

After updating to vaadin-bom 10.0.6 it works. Seems to be related to vaadin/spring#331.

The include at the end to build the executable JAR is missing the production profile

At the end of the tutorial, in the "Build an executable JAR" paragraph, the build instructions are missing the "production" profile that actually builds the frontend files to include in the JAR.

Without this, running the jar and trying to access the application produces an error page and this in the console:

java.lang.IllegalStateException: 

  Failed to find the following files: 
      - ./generated/jar-resources/lit-renderer.ts
      - ./generated/jar-resources/vaadin-time-picker/timepickerConnector.js
 [etc...]

includes in AsciiDoc do not seem to support a parameter that could contain the missing "-Pproduction" (for Maven), though.
