Thanks for the response... I do have some questions.
I have to look at a GenericMVCPortlet...no idea how that can be done. I was always assuming that following the JSP portlet explaination in the tutorial will get me around...So there is absolutely no way to get it work still using JSP portlet? I have most of my portlets in JSP and do you think it will be a lot of work converting all those to GenericMVCPortlet?
You can still use JSP portlet. It you look at JspPortlet, it derives from GenericMVCPortlet.
I don't think it would be alot of work to switch to GenericMVCPortlet though. Just change the parent in the XREG to GenericMVCPortlet and change the base class in your code to the same. Also, add <parameter name="viewtype" value="JSP"/> to the xreg entry. For examples, look at the admin's registry browsers, like the PortletBrowser.
You said:
"Using this portlet, when running the action events, you can switch
templates. This will changes the template used during the render phase of
the portlet. Basically, when using the GenericMVCPortlet/Action, actions
will be executed first, where you can perform logic and add things to the
context. Then, the template will be rendered. The template rendered will
be the one set in the xreg file or the one set by the setTemplate function."
If i understood you correct this will be like a master portlet executing all the actions. So if i have a button that maps to an action or a link that needs an action in the link then this action needs to extend GenericMVCAction not JSPPortletAction. Is that correct? Can you help me here with a sample?..will really appreciate it.
JspPortletAction derives from GenericMVCAction, so your code does not need to change.
Basically, this portlet action would have all of the action events needed. Again, look at the admin's PortletBrowser for an example. Basically, by using the JSP versions of the GenericMVC, the only thing that is different is that you can't switch to velocity templates by simply changing the viewtype parameter.
You said:
"When using setTemplate, you will always need to have another method to send
you back to the original template. Or, you can always log out."
This means that if i say "setTemplate" from Configuration.jsp to addNode.jsp then i need something in AddNodejsp's context setting the page back to Configuration.jsp. Is that what u meant? that is what i was doing in the doCancel of AddNodeJSP in the example i gave you.
Thanks again,
Regards, Archana

First, create a portlet whose parent is GenericMVCPortlet. This portlet will set the parameter "viewtype" to JSP. Second, create an action which derives from GenericMVCAction.
Using this portlet, when running the action events, you can switch templates. This will changes the template used during the render phase of the portlet. Basically, when using the GenericMVCPortlet/Action, actions will be executed first, where you can perform logic and add things to the context. Then, the template will be rendered. The template rendered will be the one set in the xreg file or the one set by the setTemplate function.
When using setTemplate, you will always need to have another method to send you back to the original template. Or, you can always log out.
