First thanks for your reactivity. I sent message to struts-user list before I post here .
The evaluation of the expression can not be done during jsp processing because
1- custom tags are processed defining a datatable
2- table is then sent to browser
3- click each cell in the same column will request an URI with the same EL expression (specific to a column)
4- elExpression is supposed to be evaluated by the controller
I can not evaluate each EL Expression for each cell, since only one cell will be clicked.
I hope my problem is more clear, now.
Any Idea ?

Hey Denis,
- first of all, this is really the list for non-struts taglibraries, for struts issues please refer to [EMAIL PROTECTED] - second, I'm not that sure what you mean, but can't you use the struts-el taglibraries to create the param at the time the link is created? I think the el-taglibs are in the struts 1.1 distribution.
Grtz,
Martin

Hi,
The idea is an hyperlink on HTML Page calling a Struts Action and with an URI ending with like myAction.do?elexpression="sessionScope['mylist'][param.row]"
So I need the ELanguage power in my Action.execute( ) method. I tryed to get a PageContext( ) from JSPFactory.DefaultFactory( ) (using current request, response,etc ) but now my container (Jetty) send JSP source instead of JSP processing result.
-------------------------- public class DetailHandlerAction extends Action {
public ActionForward execute( ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
PageContext pc = JspFactory.getDefaultFactory().getPageContext(this.getServlet(),request, response, null, true, 4096 , false ); evaluatedDetailRef = ExpressionEvaluatorManager.evaluate(null, detailRef, Object.class, pc); javax.servlet.jsp.JspFactory.getDefaultFactory().releasePageContext(pc); ----------------------------
Any idea ? Thanks for your help. Denis.
