dynamically set called element in reusable sub-process

[Marco Antelmi]

Hi,

i'm trying to use the "reusable sub-process" activity in the workbench bpmn editor. I have defined two sub-process and I would dynamically set the "called element" parameter: the called sub-process depends on some main process inputs.

So, I set a variable in a script task (invoked before the  "reusable sub-process" activity), with the following code: "kcontext.setVariable("processId", "processX");".

In the "reusable sub-process" I set the "called element" parameter to #{processId} but it doesn't work (the engine couldn't resolve the expression #{processId}).

Is there a way to get the value of the variable "processId" in the "called element" parameter?

Thanks,

Marco

it is certainly a supported feature. Can you share your bpmn2 xml file so we can inspect it?

Hi Maciej,

you can find the main process bpmn attached.

When i try to start the process i receive the following error: "Unexpected error encountered: [FinWf.GenericWorkflow:5 - call sub process:3] -- Could not find process #{processId}".

Thanks,

Marco

Marco,

the reason for this is that you didn’t declare process variable for processId. Once you do that it will work just fine, see snippet here(added two lines in blue to your process definition):

<bpmn2:itemDefinition id="_subXItem" structureRef="String" />

  <bpmn2:process id="FinWf.GenericWorkflow" drools:packageName="org.jbpm" drools:version="1.0" name="GenericWorkflow" isExecutable="true">

    <bpmn2:property id="processId" itemSubjectRef="_subXItem"/>
