I have a process definition has the following scenario:
- node 1, performs an action which calls executionContext.leaveNode() when done.
- This does a default transition to a ProcessState, which has several nodes in
it. All of their action handlers perform similarly to node 1.
- Upon completion of the subprocess, The ProcessState then makes a default
transition to another node whose action handler is again similar to node 1, and
makes a default transition to the end-state.
In 3.2-GA, this works without any difficulties, but in 3.2.1 it throws an
exception saying that the current token is locked. Is this a bug or expected
behavior? I don't have enough understanding of the purpose of token locking to
really see how to change my code to work with it.
Below is the log output. Thanks in advance for any help!
