Sumeru Saha [https://community.jboss.org/people/sumerus] created the discussion "Re: Exception Handling in jBPM" To view the discussion, visit: https://community.jboss.org/message/831135#831135 -------------------------------------------------------------- Hi Maceij, We're trying to perform some exception handling in our process. What we have is Script Task 1, Use Task1, ScriptTask2, ScriptTask3 (in order) ... in ScriptTask1 i'm setting a process variable (say, someVar) to some value before landing into the UserTask1. I can see the process variable value refelected in the portal screen. In Script Task2, i'm again setting variable to a different value and finally in ScriptTask3 a java.lang.NPE is thrown. What we observe is that the value of the someVar still has the first value which was set in ScriptTask1 and the value set in ScriptTask2 is rolled back (which is a desired behavior on exception). But the problem is that now the instance is stuck at the ScriptTask3. How do I route this instance into an exception flow or an alternate so that some corrective step can be taken either manually  or systematically and the instance can be salvaged. Please help with ur valuable suggestion.
