Hi, I have some process variabless passed via map in startProcess. AFAIU these represent the current state of my process instance so what I would like to do is compare these in a condition of a wait state node against an inserted fact, which would be the dynamic (changing) part (Because I imagined that this is what wait nodes are mostly good for, hope I'm right...). AFAIK this node accepts only rule syntax (no mvel or java) so ATM I managed to do it with eval, see code below, but it is ugly: transaction : TransactionDAO( ) #this is the changing part processInstance : WorkflowProcessInstance() #this is the process level eval( ((APSSender)((BaseForm)processInstance.getVariable("form")).getDao()).getTransactionId().equals(transaction.getTransactionId()) ) As you can see the left side in eval is a nested object. In java it would look like simply form.getDao().getTransactionId(). My question is how can I do it with rule syntax without eval? Is it possible? I was experimenting like a whole day with no success. Please help! Thanks Marton -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Nested-access-to-proc... Sent from the Drools - User mailing list archive at Nabble.com.
