When my portlet does something by clicking on an action URL ( renderResponse.createActionURL), I set some attributes in the performAction method (i.e. actionRequest.setAttribute("current_state", stateABC))
I intend to have the doView retrieves this state and then select an appropriate JSP to dispatch to.
BUT, in doView(), the renderRequest.getAttribute("current_state") is null.... Is it the expected behaviour? Why is it so?
I want the state to last for just the request scope, so, when the goes to another page and then back again, my portlet will display a default state.... How can I achieve so?? (Because i found the actionResponse.setRenderParameter() will last for not just the request scope... but until I have another render URL / action URL clicked).
