Hey All!
Just for the record,
<c:out value="${requestScope['org.apache.struts.action.Module'].prefix}"/>
(Incorrect)
^^^^^^
<c:out value="${requestScope['org.apache.struts.action.MODULE].prefix}"/>
Along a similar note, how would one work out the name of the tile definition
being processed ? Any ideas ?
TIA,
Kunal

This isn't a bug, it's a feature :-). Actually, this happens because
the "." character is an operator in the EL syntax, so it can't be used
literally in an expression. Try something like this:
The prefix is <c:out
value="${requestScope['org.apache.struts.action.Module'].prefix}"/>
instead. This works because the "." operator and the "[...]" bracket
syntax are treated identically in the EL syntax, just as they are in
JavaScript. Therefore, you have to enclose the string constant that
includes periods in quotes to make things work as you expect.
