Portlet Retain previous Contents - J2-M3

[Santiago Urrizola <ch...@yahoo.com.ar>]

Hi all,
i hace a lot of aplications runnin as StrutsPorlets in J2, they works fine, 
but have a serious problem, than i couldnt fix yet.

I have a link in the left panel to a psml call list.psml

This psml contains a portlet call mt-usuarios::ListClient
    <fragment id="cuenta.datos.1.1" type="portlet" 
name="mt-usuarios::ListClient">

This portlet is defined as a struts porlet like this
        <porlet id="ListClient">
        .....
        <ViewPage>
        <value>/client.do?accion=list</value>

where client.do is a dispatch struts action that contains two methods
        list         -> lis all the clients in the system, and forward to 
list.jsp
        view       -> view one selected client and forward to view.jjsp
        remove    -> remove one selected client. and forward to 
operation-ok.jsp


The firt time you click the link in the left menu, the application works 
fine, show me the list.jsp page, then i select one cliet, and show me the 
view.jsp. This is ok. There ir back to the home, or click another link in 
the menu, when i click again in the client link in the left menu, they show 
my the view.jsp (and execute the view methor in the action), this is the 
previous context of the portlet,
It posible to reset this, i whant when j1 load a psml, call always the view 
page of the portlet, not show the initial contexto.

Please i need help with these, i spend a lot of time solving this.
Santiago

You need to build your Struts application in a MVC proper manner. In
portlets you have "Action" request (changing inner state of app; i.e.
removing a user or changing his attributes) and "Render" requests
(displaying the current state of the app; i.e. showing the list of user
after removing one). Struts is based on Servlets, but since you are in a
Portlet environment you need to reflect (a bit) the workflows defined in the
Portlet spec.

Struts actions that are rendered using the <link ...> tag of the
Struts-Portlet TLD with the attribute "actionURL='true'" shall not do
immediately forward to a JSP. Same, when you POST a form (and use the "form"
tag of this TLD). Both make your request being an "Action" request and are
supposed to change the inner state of the App.

You should have another Struts Action your forward to from your
"Action"-like struts action. This one is the "Render"-like action. Finally,
you should have the attribute "redirect='true'" included in your forward to
the finally called "Render"-like action.

When you develop Struts applications in Jetspeed2 you *really* should read
http://portals.apache.org/jetspeed-2/multiproject/portals-bridges-struts/fea
tures.html

Saves you a lot of headaches (and gives you a lot in the first place, but
this cannot be avoided, anyway ;-))

Don't know where this comes from. But maybe if you fix the problem above,
this one will disappear too.


Sven.
