I've looked at the message below, and it appears that your proposal is different from the current implementation within the Struts 1.1 beta.
If I'm wrong, please let me know. I opened a bug on this at http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7393, and saw that you responded to it - but I can't tell if your response is confirming the bug, or it is "as designed."
