VariableInstance out of sync with DB

[dserodio]

I'm chasing a nasty bug in our app, and I've narrowed it down to the following problem with jBPM:

I have a process variable which is updated on every TaskNode (by means of a script). At one point, when I call

token.getProcessInstance().getContextInstance().getVariable("myVar")

, it returns the previous value of myVar (ie, the value it had at the previous TaskNode). Looking at the database, I see the same VariableInstance with the "correct" (current) value.

The in-memory TokenVariableMap is out-of-sync with the database. What could be causing this problem? How can I work around it?
I tried calling

jbpmSession.getSession().refresh(tokenVariableMap)

inside the debugger, but it didn't make any difference.

Can you provide a JUnit test showing the problem?

I can reproduce it with a (Selenium) functional test, but that would require deploying our webapp to reproduce it.

I'll try to write a unit test for this problem, and keep you posted.

Thanks,
