I have an ActionExceptionHandler (see code below) that works fine with
Struts 1.1, but bombs with a nightly build (Nov. 20th). With Struts
1.1, I get an error on on my input page that reads:
The process did not complete. Details should follow.
No row with the given identifier exists: 3, of class:
org.appfuse.persistence.Resume
With the nightly build I get:
The process did not complete. Details should follow.

Should I try a more recent nightly build?
