This is my JSR struts porlet. It loads fine and displays 1st jsp and 2nd jsp.
But when I browse the other pages and click back on the tab for
my portlet, it displays the second page that was displayed earlier and not the
initial page.
I have 3 .jsps . First index.jsp forwards to firstFormPage.sjp
that has a button. When the button is clicked, a action is invoked that forwards to
pageDenied.jsp

When I click the portlet tab again, instead of displaying page with button, it
displays the second page. But, when I close the browser and open again, it displays
the initial page with button.

setting expiration-cache to 0 in portlet.xml did not help.

Is this action class problem ?

Please help

Hi,

By default the pages are picked from cache and not directed from the initial action on subsequent clicks.

Add the following line at the end of the JSP pages , if you want to follow the same execution pattern everytime.

<% WpsStrutsUtil.removeCommand(renderRequest,renderResponse,"view"); %>

To use that you ahve to import the package like this :
<%@page import="com.ibm.wps.standard.struts.util.WpsStrutsUtil"%>

Consider Paul's rocket mass heater.
