Temporary Error Using CX_BO_TEMPORARY

Question

I am creating a workflow using classes rather than BO's for the first time.  I want to use a temporary error and see that the suggested way to do this is to raise exception CX_BO_TEMPORARY.  I'm not having any luck getting this to work. 
I have created a class with a method that does nothing but raise the exception with the simple syntax "RAISE EXCEPTION TYPE CX_BO_TEMPORARY.", this is the only line of code in the method.  I then created a task in my workflow to call this method and set it up to handle temporary errors on the Misc tab.
The workflow goes into error rather than temporary error.  It has a message "An exception with the type CX_BO_TEMPORARY occurred, but was neither handled locally, no declar....". 
I also tried adding CX_BO_TEMPORARY to the exception tab on the method itself and raising it using it using the same syntax.  I did not model this outcome in the workflow.  The workitem remains in "in process" status and does not go into temporary error.  I try running RSWWERRE 3 or 4 times and the workitem never goes into error status.
Any suggestions on what I am missing here?

Answer 1

Figured out what was happening here.  Simple problem, I accidentally missed activating one of the methods from the IF_WORKFLOW interface.  Short dumps were getting generated causing the workitem to stay "in process".
