I solved my problem, but I think that this is an ODE bug or
misunderstanding about events.
The problem was that I receveid a VariableModificationEvent, but asking
for the variable value through the eventContext, I was getting null.
The problem was that the variable for what I'm receiving the
VariableModificationEvent, was not in the current scope, but in a parent
scope: so the only solution I found was storing also the previous
contexts and when such situation occurs, I search also in the previous
scopes (the parent scopes).
This workaround works only if the process is executed with "in-memory"
mode, and I think that this can be a problem in real world processes.
Any suggestion ?

Hi all,
I have a problem on a listener that I wrote for monitoring my processes.
My process contains a Invoke activity, so the events that I receives are:
.....
ActivityExecStartEvent:
Type = activityLifecycle
ActivityType = OInvoke
ProcessMessageExchangeEvent:
Operation = getOrder
VariableModificationEvent:
Type = dataHandling
VarName = wsOutput
ActivityExecEndEvent:
Type = activityLifecycle
ActivityType = OInvoke
.....
In correspondance of the VariableModificationEvent, I try to retrieve
the variable value through the EventContext, but I receive null.
I tried also to delay the retrieving of the value in the
ActivityExecEndEvent, but I get always null.
Is there a way to get the value of the response variable used in the
invoke activity ?
Thanks
