[jboss-user] [JBoss jBPM] - Problem with a decision node in a fork, join construct.

[janvandeklok]

Hello,

 I'm using jbpm 3.3.0.  and we noticed a problem with the following process construction:

 a fork that splits into 3 decision nodes, these decision nodes transition to either a task node or directly toi the join.
Transitions from the decision to the task node are OK,  transitions from the decision node directly to the join will throw a StaleObject  Exception when trying to update a token for the fork.

We use Oracle 10  as the database.

Is it a bug or what ??

any help is appreciated!
