Problem with BPMN2.0 Dataflow [message #892459]

Hi Everyone,

So, this I'm having right now a Problem when I try to parse a BPMN2.0 file that has dataflow elements associated to it.
I've tried almost everything, here I post some examples I've used:

1). This example has an association of one data input object and one dataoutput object, both data objects are defined after the task.

<task completionQuantity="1" id="sid-E52D1B8B-5CAC-4FC4-93C4-0754F601C976" isForCompensation="false" name="Task1" startQuantity="1">
         <incoming>sid-E2E3A294-1852-4F7C-BD5E-0D370BA548F2</incoming>
         <outgoing>sid-6D8AB201-CC1E-41BC-9BDB-03104E0214B4</outgoing>
		 
		 <ioSpecification>
			<dataInput id="dataInput" isCollection="false" />
			<dataOutput id="dataOutput" isCollection="false" />
		 </ioSpecification>
		 
         <dataInputAssociation id="sid-F2D9423B-0E4B-4F48-BF2F-40B9E282F3CB">
            <sourceRef>Inputobj</sourceRef>
            <targetRef>dataInput</targetRef>
         </dataInputAssociation>
         <dataOutputAssociation id="sid-ACB1597E-1959-4EA3-8ACD-BC361C705152">
            <sourceRef>dataOutput</sourceRef>
            <targetRef>Outputobj</targetRef>
         </dataOutputAssociation>
      </task>
      <dataObject id="Outputobj" isCollection="false" name="OutputTask1">
      </dataObject>
      <dataObject id="Inputobj" isCollection="false" name="InputTask1">
      </dataObject>

I'm getting this error: org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'org.eclipse.bpmn2.impl.DataObjectImpl@77485542 (id: sid-942EA3F7-9F55-4E4A-A38A-29E226CEBC0C, anyAttribute: null) (name: OutputTask1) (isCollection: false)' is not legal.

... 15 more

Somehow the values of the DataObjects I have are wrong, but I can't figure out why, all the associations seem to be correct.
Please a little bit help there Smile

Thanks in advance!

Hi Omar,

I tried copy/pasting the above task into a new process and didn't see the exception here. This DID point out a different problem in the Property Page for Task I/O Parameters: https://bugs.eclipse.org/bugs/show_bug.cgi?id=383829

This should be fixed in the next build scheduled for 6/29/2012

Thanks for finding this Smile

Thanks! but, maybe i didn't explain myself good enough hehe.
The problem I have is that, when I start parsing the file, once it gets to the part where the Data Objects are, it just says that the values are not valid, as if it had found an incorrect structure..

Here I insert the whole bpmn2.0 file code:

OK couple of things:

1. I had to add a bunch of namespace definitions just to get this to load
2. the DataObjects should not be child elements of <lane> because DataObject extends FlowElement, and Lane.flowNodeRef must be a FlowNode
3. the first BPMNShape element in your process refers to a non-existent bpmnElement (I'm assuming it was a Lane that has been deleted at some point)

Here's the (slightly) modified process file:

Ok I made those changes, but somehow last time I copied the example here I had to delete the namespace definitions because the forum was giving me some error with links or something, this time I post the example ASAP without lanes, just one Service task that receives the input and returns an output. Still not working..

Here the link to the file in ge.tt : ge.tt/2dxtL0L/v/0?c (I can't post links beacause of Eclipse's Forum's policies.. so put in front of ge.tt the http part Smile

Thanks a lot once again and sorry for any inconveniences Smile

Hi Omar,

I've found the problem Smile

The example you posted is not valid BPMN 2.0 for the following reason: the DataInputAssociation and DataOutputAssocition both refer to their containing ServiceTask (with "targetRef" and "sourceRef", respectively). The problem is that these references must point to an ItemAwareElement according to the BPMN 2.0 spec. However, ServiceTask is NOT an ItemAwareElement (besides being the container for the DataAssociations) and therefore can't be the source or target of the DataAssociations.

Hope this helps
Bob

P.S. I'm curious: where ARE you getting these models from? They are obviously not valid BPMN 2.0 so they couldn't have been created by a compliant editor or tool... ?

Hi once again!! So, I think I might have found the problem with the BPMN 2.0 files that have data flow, I took the example from this page:

github.com/droolsjbpm/jbpm/blob/master/jbpm-examples/src/main/resources/junit/BPMN2-ServiceProcess.bpmn2

And when I parse it everything works perfectly, but the litle problem is that the elements involved here (startevent id="_1", servicetask id="_2" and endEvent id="_3") don't have incoming or outgoing elements in them, and they should. When I add to each of those elements incoming and outgoing elements that specify a control flow, and once again try to parse the file.. I get errors of "incorrect values".

Here the example once added the incoming and outgoing:

ge.tt/6P3hzdL/v/0

So I would say that the problem resides in the fact of using data elements together with incoming and outgoing elements.
What do you say? Smile

Thanks again in advance!
Regards!
