Possibly related to #16 and #17, we've been using your BPMN engine successfully now for a number of months with no glitches, but we recently had a requirement to modify rather than add one of the properties on a process instance. When we do this using setProperty, it shows as modified when using getProperties, but is left unchanged in the database. If there is a simple fix for this, we'd very much appreciate a patch.
Hi,
I'm trying to use e2ebridge/bpmn in a meteorjs app to replace a BPM system previously written in Java (using Activiti).
I'm having some trouble as I want to use Meteor's reactivity to show a task list from the MongoDB. All was going well but it seems that when I call taskDone it doesn't flush this to the database. Is there a way to force a persistency flush or to make the persistency more eager? If not, can you guide me as to modify the code to do it as this is becoming something for a deal-breaker and I'm under pressure on this project! Thanks,
Chris
I am trying to set properties in EXCLUSIVE GATEWAY events caught by below handler.
exports.defaultEventHandler = function(eventType, currentFlowObjectName, handlerName, reason, done) {
//Called, if no handler could be invoked.
console.log('defaultEventHandler ' + eventType + currentFlowObjectName);
this.setProperty('Date()','Date()');
done();
};
console says
defaultEventHandler callHandlerStateChange1
but the properties is not set the mongo database.
can you help me out? Please.
I am having trouble clustering the bpmn using pm2. I can only find process that were created by that node of the cluster. is it possible to refresh the process cache from what has been persisted to the data store?
Hi,
I have the following code:
var bpmnParser = require('bpmn/lib/parsing/definitions.js');
var processDefinition = bpmnParser.getBPMNDefinitions('./expenses_payment.bpmn');
and it returns a result like:
[ { bpmnId: '_Collaboration_3',
participants: [ [Object], [Object] ],
messageFlows: [],
isCollaborationDefinition: true } ]
The question is why this function always returns an array? I seen that in most of cases it always is
just one object.
There is a case when this fn. will return more than one object?
Regards.
Hi all and happy holidays,
I am new to node, I can't not understand how to start a new bpmn project in node, and how to start a new process and how to Handel in the handlers, can anyone help me with sample bpmn project in node or point me to documentation explaining the above.
Thanks and appreciate in advance
The project remains in development? or has it been abandoned? please answer us
Hi,
Would there be any interest in pulling this if I implement it? I think RethinkDB + BPMN are very cool, complimentary technologies.
Hi,
Not sure why, but I'm having processes getting stuck at converging parallel gateways. Is this a known problem? Is there anything can be done about it? I've attached the process diagram. The orders seem to get stuck occasionally in "Order Built" and "Doors Built". I've tried a few things to work around it thinking it might be to do with the combination of exclusive gateways and parallel ones (ideally I want an inclusive gateway - is that anywhere near available?) e.g. I inserted a "Doors Start" activity which just calls done and "Track Cut" etc. to join the exclusive gateways (I couldn't get exclusive gateways to join any other way).
Please help! I was SO pleased when I found a Javascript BPMN engine but I'm now getting ready to give up and just go back to using Activiti via REST!
When flow reaches the subprocess - handler is being called and then flow ends. No handler for start event in subprocess is called and I haven't found any functionality to start sub process. Any ideas on how to get this done?
Hi guys,
Trying to set up a simple BPMN as in this gist:
https://gist.github.com/darbio/ee2a25d951fdbbd93491cd220f706a35
The process won't progress from Send email
to Create user
.
I've tried a number of different definitions, including the simple Task.js and it's still not progressing with my code.
Cheers.
Are the provided example bpmn files supposed to be viewable in any BPMN2.0 compatible modeler/viewer? I'm having trouble opening them.
bpmn.io gives no errors but draws no diagram.
camundaModeler gives a bunch of errors and draws no diagram.
Errors examples (on opening collaboration.bpmn
):
feature 'label' not found
feature 'mxCell' not found
BPMNPlane not associated with collaboration
Element *N*: Diagram element not found, element will not be shown
Then there's yaoqiang, which does display a diagram, but warns that the xml is malformed and should be fixed.
What viewer/modeler can I use to open the example files?
Should I expect issues when creating new bpmn files with one of these modelers? (I'm planning on using bpmn-js/bpmn.io)
Please add examples for CallActivity/SubProcess and saving user tasks.
I designed a workflow using Camunda's bpmn-io, which is a great Javascript/HTML designer/viewer. However the generated BPMN looks completely different than what you have in your samples. Here is an excerpt from both...

I am new to BPMN, but shouldn't these two be compatible? Shouldn't I be able to design a workflow in any bpmn designer and execute in any execution engine?
Hi,
Please a question..
How can Implement assignee to the user tasks, how can associate a assignee name, to user tasks??
Best Regards.
I assume that the implementation of boundary events are interrupt which means the activity which was being performed will immediately be canceled,
That's right?
So, there is a way to implement non-interrupt boundary events?
Best Regards.
When I try to load a process wiht
var path = require("path");
bpmn.createUnmanagedProcess("./plan/myDiag.bpmn", function (err, myProcess) {
// we start the process
myProcess.triggerEvent("MyStart");
});
the handler.js file tries to load the associated .js file (myDiag.js) from the location the handler.js file is located. in my example the handler.js file is ...../node_modules/bpmn/lib/handler.js, which is not the same folder in which my myDiag.bpmn file is located.
db connections are closed when a process is done and has no parent. This holds water when a process was launched via a bpmn 'call activity' which is where the notion of 'parent' exists. AFAIK collaborating processes don't seem to have any parent processes but they do have participants who may, and more often than not, are, still in a 'processing' state. Currently the connection to mongo is terminated when a processes ends if it doesn't have any parents. But since collaborating processes don't necessarily have to have parents the first one to complete will kill the connection to mongo. I may be doing something wrong here so if so please let me know. Otherwise, if this is a legitimate issue I'll fix and do a pull request.
Just let me know,
thanks.
Probably this is an stupid question, but how do I tell the engine that a task is done using the REST server?
howa can i define frontend route with restify!
Is it possible to get the bpmnId of a task inside the handler ?
Something link that ?
exports.mytask = function(data, done) {
console.log(this.bpmnId);
done(data);
};
We get [Error: The BPMN file '...'. contains more than one process definition. Use 'createCollaboratingProcesses' instead of 'createProcess'] if no executable definition is found which is wrong
Hi ,
I have tried the collaboration process in rest way , I use the example : test/resources/projects/collaboration/collaboration.bpmn
, howerver , I got the the following result
error: process=My_Second_Process, id=1fc883b0-6593-11e4-9b73-eb590f76728b, description=Error in handler 'Task_2': TypeError: Cannot read property 'processClient' of undefined
I changed the name of every node with underscore for rest .
client.post('/My_Second_Process/Start_Event_2',function(error, req, res, obj) {
});
this.getParticipantByName("My_First_Process")
does not work.
exports.Task_2 = function(data, done) {
log("Task_2");
this.getParticipantByName("My_First_Process", function(err, partnerProcess){
partnerProcess.triggerEvent("Start_Event_1");
done(data);
});
};
Thanks a lot .
From documentation and source code it is not clear.
Hello,
Running a trivial sample, I get the following message:
$ node myprocess.js
[Error: The BPMN file '/.../myprocess.bpmn'. contains more than one process definition. Use 'createCollaboratingProcesses' instead of 'createProcess']

However, the process definition contains a single process.

Can we Use lanes in BPMN ?? How to use in this git example
I like to implement BPM engine in Node to execute business process we are using your bpmn package and it works fine. I do have some queries
Can we introduce organisation and lanes in your module. If yes then how can we implement ?
In the package.json, "mongodb": ">= 1.3.10", I think it is not better way to dependency,
generally, major version changes means API not compatible with previous version, now, we need to upgrade mongodb to 3.x, which is causing bpmn is not working.
I am using timer event in my workflow. i am not bale to pass data using done(data)
Hi Team, first off CONGRATULATIONS for such a great project.
I would like to know if is there any plan to support Data Object elements? It would be really awesome for the engine since it allow to describe many technical topics on the model itself.
Looking forward to your feedback,
Best Regards, Rolando
Hi,
I saw that to use
bpmn.createUnmanagedProcess("path/to/myProcess.bpmn", ...});
or
bpmn.createUnmanagedProcessFromXML("<definitions ... ", ...);
the first parameter is always the bpmnXml source,.. I know that XML Parsing is a little hardest work,
and it consume resources (processor and memory),..
I think that if we are always passing the bpmnXML source as first param, it always is parsing the schema to json. The question is, is there a way to persist the first parse of the schema,. (or cache), to do not parse the xml each time that we need to use an instance of a given process.
By example:
------------------------------------------File A ---------------------------------------------
var processManager = new bpmn.ProcessManager({
persistencyOptions: {
uri: util.format('mongodb://%s:%s/%s', config.db.host, config.db.port, config.db.name)
},
bpmnXML: {name: 'TaskExampleProcess', xml: bpmnXML},
handlerString: {name: 'Process1', string: handlerString}
});
processManager.createProcess("instance2", function(err, myProcess){
if (err) throw err;
// we start the process
myProcess.triggerEvent("StartEvent_1");
console.log('process started');
});
------------------------------------------File B ---------------------------------------------
var processManager = new bpmn.ProcessManager({
persistencyOptions: {
uri: util.format('mongodb://%s:%s/%s', config.db.host, config.db.port, config.db.name)
},
bpmnXML: {name: 'TaskExampleProcess', xml: bpmnXML},
handlerString: {name: 'Process1', string: handlerString}
});
//// returns all processes
processManager.getAllProcesses(function(err, processes) {
console.log(processes)
});
So, on both files I need to pass bpmnXML string, and I assume that the engine is parsing twice the xml.
The best way would be parse the xml at first time, give me an ID,... and on the second file B, I create the processManager instance with the given ID, and do not pass again the XML.
BEST REGARDS.
I see that you can specify a global unhandled exception handler callback per process in your js file. If I model script exceptions as an intermediate error event in my bpmn file, is there a way to raise those events when the script error occurs? Would I use a try/catch and trigger the event manually? If so, how?
I am new to BPMN so hopefully I missed something in the docs.
The engine cannot find the Javascript file:
My process looks like this:
var bpmn = require("bpmn");
console.log("Start process")
bpmn.createUnmanagedProcess("bpmn/simpleRegistration.bpmn", function(err, myProcess) {
// we start the process
myProcess.triggerEvent("Start_registration");
});

A basic manager:
var bpmn = require("bpmn");
var manager = new bpmn.ProcessManager();

Hello Team,
I have created a bpmn process and it executes well. Is it possible to get the specific running instance of process and validate any of the task (Human Task) from the process using the instance.

This could help to propagate data through the process if it uses a defaultEventHandler. Or did I miss something?

Why there should be a 'JS' file specific to a process to contain handlers? If I design a new process do I need to create handlers for that process too?
Hello Team,
Could you please share any example of handling the intermediate message event.
Thanks
can you provide any sample web application which contains listener events and also extensions uses.
Is there someone that could provide an example when we are facing to a "decision" scenario? I'm trying to understand where we should specify the decision process and how to trigger the next step. Thank you for your help
