Hello,

I'd like to set a process variable of a workflow B while in the Java code called in the <event type="node-enter"> of a workflow A.

In other words, I'd like to realise the equivalent to "executionContext.setVariable("varName", value)". But how can I get the equivalent to "executionContext" of workflow B since I am not in the context of workflow B ?

Is it possible ? If yes, how ?

Thank you for your help

Hello,

this is not possible without some major jBPM coding, e.g. using the "low-level" jBPM API in an action handler to gain access to the other process instance via jBPMs process instance management API / services.

Why can't you use the WorkflowService and update task properties with the appropriate method? It is nearly the same as setting a process instance variable, as tasks submit their variables per default into the process instance context. You could define an ever-present system task (assigned to user "System") and have that task transition back to itself right after updating the properties..

Other trail of thought: When these workflows are so inter-related, why are they not distinct, parallel forks within the same process definition or sub-processes (granted, I have not tried working with sub-processes in Alfresco's jBPM engine)?
