Hi All,

I'm attempting to build some portlets and keep running into issues limited by my Java experience and deadline crunches. What I'm attempting at the moment is a selection page that posts to a display page that contains a Jasper report. What I am trying to determine is how to set conditional view methods. I'm using MVCPortlet and I have the following action request:

1
2@ProcessAction(name = "getFundingStatusAction")
3public void getFundingStatusAction(ActionRequest actionRequest, ActionResponse actionResponse) throws IOException, PortletException {
4
5       String[] selectedCountries = actionRequest.getParameterValues("countryList");
6
7       if (selectedCountries != null) {
8          //actionRequest.setAttribute("countryList", selectedCountries);
9          actionRequest.getPortletSession().setAttribute("selectedCountries", selectedCountries);
10
11          actionResponse.setRenderParameter("jspPage", "/html/fundingstatus/fundingstatus_report.jsp");
12       }
13 }

When my portlet routes to fundingstatus_report.jsp my generic doView is not being called.

My question is how do I tell the actionResponse what the Render View method should be?

Thanks!

Hi George,

It's a default behavior of portlet that after any Action, doView will be called immediately.
Still if you are facing some issue then override doView method in your own class.

Set parameters & write your own conditions on that basis in doView method.

Hey Vipin,

Thanks for the response - but the doView is NOT being called when I use the renderParameter and a key of jspPage. It's getting skipped. I also tried it as a GenericPortlet with the same result.

Please check out this method:
void javax.portlet.StateAwareResponse.setRenderParameter(String key, String value)

if the value is blank then it will redirect to the default page, otherwise you can specify the view to go to.

I have that set - but it's not calling the general doView for the portlet. How do I tell the jsp page/view what function to call within the base class?

Any other ideas out there? Does the display for the secondary portion need to be in a new portlet? I know a portion of my problem is just understanding portlets in general. Maybe my workflow is incorrect? What I'm trying to do is the following:

Initial View with Combo Box and Form -> Posts to Action -> Load second jsp as View -> Provide reset button which posts to Action -> Displays combo box and form like Initial view.

Thanks,
George

In your action-method, try with the parameter-name as mvcPath rather than jspPage.

OR

After action it goes to render() method. Try overriding render method in your custom portlet class.

1 @Override
2 public void render(RenderRequest request, RenderResponse response)
3          throws PortletException, IOException {
4       // TODO Auto-generated method stub
5       super.render(request, response);
6 }

OR

If you don't have any conditional decision for view-jsp (after action), then below also works from the jsp

1<portlet:actionURL var="editGreetingURL">
2 <portlet:param name="mvcPath" value="/view.jsp" />
3</portlet:actionURL>

Good luck !

So what I figured out from actually reading the Liferay in Action book was that when extending an MVCPortlet it skips the doView per design. Once I got through this and loaded my responses in the action phase then set the renderParameter I was able to get my work flow flowing. RTFM, ugh! emoticon
