We are using struts-bridge and the Action class used is
"DispatchAction".
We are facing an issue when the <expiration-cache> is set as "0" in the
portlet.xml file.
Initially when the page for a tab is loaded the data is fetched and
displayed properly, whereas when we move across pages or hits the IE
refresh button we are getting the error stating the parameter required
for DispatchAction is missing. The details are given below.
Please advise us on this issue.
The error is as follows:
-------------------------
Request[/OVSRAdministration] does not contain handler parameter named
'action'. This may be caused by whitespace in the label text.
