I'm trying to set up some globals that will be visible across all of my processes.
To test it I've created the attached diagram (TestGlobal.bpmn2) which
- defines a single global string variable (globVar)
- tries to set it using a script task and the command kcontext.getKnowledgeRuntime().setGlobal("globVar", "a value") (as stated in the manual).
- tries to display it using kcontext.getKnowledgeRuntime().getGlobal("globVar").
The process compiles but when I run it from gwt-console but it throws a runtime error with the following text (full extract in error_message.txt, attached):
- org.jbpm.workflow.instance.WorkflowRuntimeException: [defaultPackage.TestGlobal:69 - Set global:2] -- unable to execute Action: Unexpected global [globVar]
This suggests that it is not sufficient to declare globVar as a global at the process level.
In an earlier effort, the display task simply tried to print the value of globVar to the log using System.out.println("Global variable:" + globVar) but this version did not even compile, complaining that globVar did not resolve to a type.
So far as I can tell I've worked in accordance with the manual - but realise there may be a key step I've missed.
Can anyone help?
Thanks
