Response Object and Render parameters are lost between processAction() to doView()

We use Weblogic 10.0 MP1 application server and created portlet using the JSR168 standards of GenericPortlet. The portlet is successfully deployed and renders all the pages properly. When we submit a form, the processAction() of the Portlet class executes correctly but loses all render parameters and request/response object states before reaching doView().

All JSR168 standards are followed to create these portlets and we have used response.setRenderParameters(parameters); to make sure that doView() has access to render parameters.

Any help is really appreciated.
