You can certainly avoid the <% request %> bit with <c:set>, something like:
<c:set var="table" value="${tablesList}" />
That set tag defaults to, I *think*, the request scope, but maybe to the
pageContext? Can't remember for sure. Give it a try.
But overall, you don't need the List.get(i++) call on there, even in the
construct you have. You're kind of duplicating effort. The <c:forEach>
iterates the tablesList, getting each item and setting it as a request (or
pageContext? Again, not sure, experiment) attribute with the var name, in
this case table. I think displaytag will grab it properly without doing
the explicit set, but I'm not sure. So something like this may work:
<c:forEach items="${tablesList}" var="table">
<display:table name="table">
</display:table>
<br>
</c:forEach>
You can try inserting a speck of code between the forEach and the display
to just print out all of the attributes in the pageContext and request
scopes (you can do session and application also, but they're not there, I
can at least guarantee that :^), and that should tell you what's living
there at each point in the lifecycle:
<c:forEach items="${tablesList}" var="table">
<%
Enumeration<String> attributes = request.getAttributeNames();
for(String attribute : attributes)
{
out.println(attribute + ": " + request.getAttribute(attribute) +
"<br/>\n");
}
%>
<display:table name="table">
</display:table>
<br>
</c:forEach>
It's hideous, both in code and output, but it's just for debugging :)
Let me know if these changes work for you or if you have any other questions.
