Bill,
Thanks for your help here. We actually ended up working down a different
path for this particular issue but I am now using this technique in
other code.
One thing we did to make the core tag code more generic was to store a
reference to the form bean in the request attributes under a short,
constant value ('formBean'). This way our el can look like
${formBean.map.txtFullLegalName}, much like the way the html tags pick
up the form bean by default. We were able to do this (setting the form
bean) consistently because we are running thru a little process type
action which is subclassed for each process.

Ahh! Bach! The wrinkle here is the DynaValidatorForm and not a regular
ActionForm ...
Try this ...
<core:if test="${studentDetailsBasicForm.map.age > 20}">
<p>do something</p>
</core:if>
For complete details ...
