Thanks for your reply.
For some reasons this does not work as intended.
I have to portlets on a pane. portlet1 displays a Velocity-Template  
with a link to portlet2. This link should also call a specified  
action-method.

The link
"<a href="$jsforward.forward('ForwardPortlet')">Portlet Forward</a>"
results in
"...default.psml/js_peid/P-fa76ed989d- 
10000?action=portlets.ForwardTargetAction"
but nothing happens.

I've changed my forward to:
----------------------------------------------------------------------- 
-------
   <forward name='ForwardPortlet'>
	<portlet id='P-fa76ed989d-10000'  
action='portlets.ForwardTargetAction'/>
   </forward>
----------------------------------------------------------------------- 
-------
I've got the portlet id from the users default.psml file.


The ForwardTargetAction should simply change the displayed Template of  
portlet2:
----------------------------------------------------------------------- 
---------
	protected void buildNormalContext(VelocityPortlet portlet,
									  Context context,
									  RunData rundata) {
		setTemplate(rundata, "ForwardTarget2.vm");
	}
----------------------------------------------------------------------- 
---------

But nothing happens. What's going wrong?

You should change a portlet's template in the action phase, not the  
render (buildNormalContext) phase.

Here is an example of saving an employee record that may be useful:

In your vm file:

<form action="$jsforward.forward('EmployeeForm', 'Action')"  
method="POST">
....
                <input type="image" src="images/buttons/save.gif"
                    border="0" alt="Save" value="Save"  
name="eventSubmit_doSave"/>

This will call the doSave event on your action.

Then in your forwards xml, one way to do this is with a portlet forward  
as:

   <portlet-forward portlet='EmployeeForm' forward='EmployeeAction'  
target='Action'/>

    <forward name='EmployeeAction'>
        <portlet id='EmployeeForm'  
action='portlets.EmployeeFormAction'/>
    </forward>

I'll update the tutorial to demonstrate forwards in actions as examples.
Let you know when its ready
