I figured out my problem. The default value of the
<rtexprvalue> for the pane tag in the tag lib descriptor is
false so it will not evaluate my scripting expression.
I changed this in my /WEB-INF/templates/jsp/tld/template.tld
to be true for the pane tag an now everything works
great.
I noticed that some of the tags in the tld file had
rtexprvalue explicitly set to false even though this
is the default, but none were set to true. Is it
a bad thing to allow scripting in the tag attributes?
I do not see another way to do what I am trying to
do.
Does anyone else need this capability? Should I submit
a patch for the tld file? If so which tags do people
wish to allow scripting in the attribute values?

Thanks Raphael,
I am trying to use the <jetspeed:pane> tag to set the pane
input for the tag's name attribute but I am running into
an issue where I cannot get the jsp compiler to treat the
tag variable as anything but a literal. My screen jsp code
looks like:
<%-- ########################################################### --%>
<%@ taglib uri='/WEB-INF/templates/jsp/tld/template.tld'
prefix='jetspeed' %>
<%@ page import = "org.apache.turbine.util.RunData" %>
<% RunData rundata = (RunData)request.getAttribute("rundata");
String pane = rundata.getParameters().getString("page");
if ( pane == null ) {
pane = "default";
}
%>
<h1>PANE = <%= pane %> </h1>
<jetspeed:pane name="<%= pane %>" />
<%-- ########################################################### --%>
My problem is that the "<%= pane %>" is not evaluated prior to
being passed into the tag code. If I leave off the quotes it
generates an exception for not having quotes. The evaluation
in the <h1> header tags works fine. It is only the one in
the tag attribute that has a problem.
I thought that I had had occasions to use variable parameters
as tag attribute values before but now I cannot seem to get them
to work. Anyone have a suggestion for a way that I can handle
this?

You can use the Jetspeed pull tool in Velocity or the <jetspeed:pane>
tag in JSP to achieve the same results.
Example of a generic "PSMLScreen" velocity template:
generic.vm
#set ( $pane = $data.Parameters.getString("page") )
$jetspeed.getPane($pane)
and use the following URI:
/jetspeed/portal/template/generic/page/mypage
These generic templates will be included in 1.3a2.
