Subject RE: XSP page getting called TWICE! (was: Pipeline dependencies)

Have you tried modifying the code to print a stack trace with each
invocation?  This might help isolate the source of each call.

Subject: Re: XSP page getting called TWICE! (was: Pipeline dependencies)


I posted this a couple of times here, as well as once to the Dev list.  No
one's written back with any suggestions so far.

I hope y'all don't mind, but I'd like to post this one more time.  It's
really stumping me!  Please help!

==================================================

Anyone have any thoughts on this?

What could cause an XSP page to get called twice in the same request?

Tnx!

DR

Although this doesn't technically cause any errors, it's pretty inefficient
since it hits the database twice, generates the xsl twice, etc.

"cocoon:/rtf_parse" generation step (not listed) is setting an "attachment"
response header ("Content-Disposition: attachment; filename=myfile.rtf") so
that the file will be downloaded instead of displayed directly in the
browser.  Could that be causing this?
