Using a localhost unit testing configuration, 
with:
Win2k professional os
jdk131_06
Weblogic server 7.0

Tried the following page (the page has been simplified for testing, with simple 
set variables for test conditions and values dependent upon the form we are 
using. 

Got the following error consistently: 
[ServletException in:/common/page/ownerInfoSummary.jsp] Could not complete 
parsing, unmatched tags: if otherwise when choose if forEach if ' 

I also recieved very similar parsing errors (parser not recognizing completed 
tag pairs, despite correct syntax)

I also tried using different tags ( c:choose with when and otherwise, etc. ) 
and got similar results.  It seems if I make the page too complex or nest too 
much logic, the parser gets really cranky.

Am I using incorrect syntax, or is this something with the taglib or the parser?
