[jboss-user] [JBoss jBPM] - Re: task-create event

[twiceknightly]

Below is a simple unit test.  What I am trying to do is set some values in the context on creation of the task in the start state.  The event is firing and my action "SetupSuspiciousTransaction" is being run.  This action sets variables in the context.  Later on I try to retrieve the variables and there values in the method "retrieveVariables".  When I step through this method "mappedName" has the right variable name but "value" has null as the value.  I was expecting to get back the values I had put in earlier.
