The Exporter class is designed to make the data in my "Model" class available
for use in jsp. It has a method "getDataMatrices()" and another
"getNameValuePairs()". I'm using the S2 tags for the "NameValuePairs", and
it works fine. I'm trying to use JSTL for the "DataMatrices", and it
doesn't work.
I've tried 2 methods of exposing the Exporter to the JSP: (1) using a
method "getExporter()" in the Action, (2) having the Action implement
ServletRequestAware, and explicitly saving the Exporter into the Request.
That is how I'd do in S1.
For either method, the S2 iterator tag works properly for the
"NameValuePairs" data. However the JSTL tags display the "DataMatrices"
only If I put the Exporter into the HttpRequest. The JSP page does not
change at all between the 2 methods. Only the Action class changes.
Of course, I REALLY don't want to implement ServletRequestAware, because I
want to test my Actions easily. Therefore I really need to make the
"getExporter()" method work with JSTL.
This page perfectly illustrates my point on the difficulty of the JSTL tags
working nicely with S2. The page works perfectly if the object is
explicitly placed into the HttpRequest. If the 'getExporter()' is the way
in which the Exporter is exposed, then it doesn't work for jstl.
