Hi there,
I had been having a problem with the following SCXML. It has a parallel
state for SLOT/TASKS. I am trying to achieve multiple transition within a
state. I am getting the following java exception: I have also attached the
SCXML for understanding what I am trying to do with it.
Any help would be greatly appreciated.
