Problem with a decision node in a fork,join construct.
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!
