Hi all again :D
I am trying to create a work item that receives certain parameters, and does stuff
depending on them.
Through the examples i created this BPMN2 file:
<?xml version="1.0" encoding="UTF-8"?>
<definitions id="Definition"
targetNamespace=" http://www.example.org/MinimalExample

</dataInputAssociation>
</task>
<sequenceFlow sourceRef="_2" targetRef="_3"/>
<endEvent id="_3" name="EndProcess">
<terminateEventDefinition/>
</endEvent>
</process>
</definitions>
I was able with this to get the parameters i defined in the corresponding work item's
handler.
Although i made it now that i want to have multiple work items like this on a single
process i have a para meter problem :( .
Is it possible to define my parameters right on the bpmn2 file?
If not, is there a way of getting the ID of the task of a workItem (i wana get that
<task id="_2"...)?
