Hi all,
being new with Portal/WCM, I am working on a kind of "search" portlet for da
ta-store.
It displays results and invite the user to clic one of them in order to view
 it. The thing is users cannot use the "previous" button on their browser wh
ich displays that the page has expired etc.

I would like to find an easy way to bring the user back to the "search page"
 with his last results list.
Is there an existing "back to previous state" tools I could use ?

many thanks

Finally I found something I think I was looking for :
<wps:portletBack>

The only thing is I was unable to use it.

let's admit I wrote something like :
<%@ taglib uri="/WEB-INF/tld/portlet.tld" prefix="portletAPI" %>
<%@ taglib uri="/WEB-INF/tld/engine.tld" prefix="wps" %>
<%@ page import="com.ibm.workplace.wcm.api.*" %>
<portletAPI:init/>

<div class="articleTitle">
<wps:portletBack>
<a href='<%=wpsPortletBackURL%>'>
<img border="0" align="absmiddle" src="<wps:urlFindInTheme file='img/picto_p
uce_title.gif'/>"></a>
</wps:portletBack>
</div>

which is quite close to the example given in the infoCenter
( Designing>Portal design reference>Tags used by the portal JSPs and then se
arch on the page for "portletBack" )

The obvious error is the wpsPortletBackURL which simply comes from nowhere..
.InfoCenter does not says many things about this value and I wondered how t
o find out what's the relative value in my portlet...

The result I obtain with the lines above is simply nothing (empty space).
So I tried to print the <%=wpsPortletBackURL%> value and I logged on error o
n my stackTrace (Portlet is unavailable)

Trace :
Nested Exception is org.apache.jasper.JasperException: Unable to compile cla
ss for JSP

An error occurred at line: 48 in the jsp file:
/view/MyView.jsp

Generated servlet error:
view/_MyView.java:299: cannot resolve symbol
symbol  : variable wpsPortletBackURL
location: class org.apache.jsp._MyView
out.print(wpsPortletBackURL);
^
1 error

Any ideas are very very welcome
