Hi all,

Here is my problem: I want to implements a "Source" page that call a second "Search" Page. The "Search" page is a simple popup that allow the user to query a DB table with a filter.

When the user is satisfied with her filter, she click on one of the found elements, and its reference is copied onto the "Source" page. Of course I want to use a display tag to display the result list :-))))

The problem is that I need to keep the "destination" field between clients calls. But I didn't find how to update the display genereated URL.

indeed if I want to do someting like:
<bean:parameter id="dest" name="dest"/>
<display:table
     name="user_registry"
     tableId="account.book"
     property="searchAccounts"
     decorator="com.my.test.display.SearchJSWrapper"
     scope="session"
     pagesize="3"
     requestURI="searchAccount.do?dest=<%=dest%>">
Display library do not replace "dest" with its correct value. I had to do a very nasty Hacks just after ... something very funny to debug such as:

<%

_jspx_th_display_table_0.setRequestURI(_jspx_th_display_table_0.getRequestURI()

+ dest);
%>


Does anybody has an idea to implements this without this ugly (not portable)
code?
Is it possible? Is it a JSP/TagLib limitation? (I actually have the same
problem with the <html:> tag)

Thanks for your help,
Didier

PS: Here is the complete code of my "Search" screen. (not cleaned up, sorry)


<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
