Portlet Process Action is not gettnig called

Problem Description : Process Action of portlet is not getting called when clicked on the WPS link (action link generated using wps:urlgenration or portlet:action) it don’t call the processAction second time

Promblem Cause: Portal will call processAction only once using the url (i.e reasonable)  . For example if we have link that is action url and opening in new window , then only first time it will call the processAction and portal will mark that link as dirty as we have called processAction using that method once. ( If we are opening page in same window then there is no way you can call the processAction second time). It is expected behavior

Solution:

Use the doview or render URL instead or copy the following in portlet.xml

                      <init-param>
                      <name>wps.multiple.action.execution</name>
                      <value>true</value>
                      </init-param>
