Hi All,
I have a problem with clearing RenderParameters below is the scenrio that i am going through
First i am using JSR 168 on WebSphere Portal
In the processAction of the portlet i set a render parameter as following
response.setRenderParameter("paramname", "false");
i use the parameter in the view jsp as following
<% if(null != renderRequest.getParameter("paramname")
&& "true".equals(renderRequest.getParameter("paramname"))){ %>
Mainly i use the parameters to display error messages
My Problem is when i refresh the page or log out the page and return to it again the error messages are still due to the existance of the renderparameters
Thanks,
|

The render parameters should be purged along with the request, so a new request shouldn't have the parameters attached to it.
Are you sure that the issue isn't page caching, as opposed to an issue with the render parameters?

Hi,
I checked the cache properties of the portal page containing the portlet and i found that cache option is setted to always expire the same for the portlet
