Subject Re: Commented code in StartCatchAction
Date Tue, 08 Aug 2006 16:10:52 GMT
It's a bug that the catch by fault type was never fully implemented.
I think the commented out code in the StartCatchAction is a remnant
from an attempt to implement the catch by fault type.  Do you think
the exception your are seeing is related to the catch by fault type
bug?  Is your invoke in the fault handler trying to access a variable
that is not initialized or out of scope?
