Pluto2: Cannot retrieve attribute from doView that set in processAction!
I donwloaded the pluto-trunk and test the pluto2 driver.
I also tried to write a simple portlet as following:
=============================================================================================
public void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException {
System.out.println("doView: " + request.getParameter("name"));
System.out.println("doView-attr: " + request.getAttribute("name"));
response.setContentType("text/html");
PortletContext context = getPortletContext();
PortletRequestDispatcher requestDispatcher =
context.getRequestDispatcher(VIEW_PAGE);
requestDispatcher.include(request, response);
}
public void processAction(ActionRequest request, ActionResponse response)
throws PortletException, IOException {
String name = request.getParameter("name");
response.setRenderParameters(request.getParameterMap());
request.setAttribute("name", name);
System.out.println("processAction: " + name);
}
=============================================================================================
In the processAction method, I set an attribute "name", but it can't
retrieve in doView. Is it a bug?
Best regards,
Eric

Eric,
Its not a bug. Action request attributes are not available in the render
phase. I think there is a runtime option for that in JSR 286, but keeping
those attributes around for possibly multiple render phases has memory
implications. Similarly, you could use the portlet session for this.
