[jboss-user] [JBoss jBPM] - jBpm 4.0CR1 - Getting variable from processInstance

[efabbri]

Hi, I have 4 process instances of 1 process definition initialized with a variables' Map. I want to list these instances and get their variables.

I call an executionProcessQuery and from it I extracted the Executions but Interface Execution doesn't have the methodo "getVariable" and I cannot get an "OpenExecution" or an "ActivityExecution" because it said "org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: org.jbpm.pvm.internal.model.ExecutionImpl.variables, no session or session was closed".

How can I do?

Thanks.

Emanuele
