Hi All,

I have a problem using the Forward service.  Here is the situation:

I have a set of portlets one of them has a detail link that uses
<jetspeed:forward> to forward to a different page.psml and portlet.  
Once
I am done with that portlet I would lile to go back to where I came 
from.
So I declared another forward to the pane that I came from.  The 
forward
to a portlet works like a champ, but the forward back does not.

Here is my forwards declaration:

        <forward name='highbill'>
            <page name='default.psml' role='csr'/>
            <pane id='P-f9a04b6fec-10001'/>
        </forward>
        
        <forward name='billnoticedetail'>
            <page name='billnoticedetail' role='csr'/>
            <portlet id='P-fa5ec14b8a-10001' action='controls.Maximize'/>
        </forward>
What I think is happening is <jetspeed:pane> tag on the Home.jsp 
checks
for the js_peid.  js_peid is the id of the portlet on the
"billnoticedetail" page i.e. <portlet id='P-fa5ec14b8a-10001'
action='controls.Maximize'/>.  This messes everything up as all I 
want is
to go to a pane on the default page.  The tag on the Home.jsp is this
<jetspeed:pane name="default"/> and the code for the tag:

if (data != null && data.getUser() != null)
{
 JetspeedTool jt = new JetspeedTool(data);
 String jspeid = (String) data.getUser().getTemp("js_peid");
 if (jspeid != null)
 {
     data.setMode(JetspeedRunData.MAXIMIZE);
     result = jt.getPortletById(jspeid);
 }
 else
 {
     result = jt.getPane(this.name);
 }
}
From this code it seems that I will never be able to hit the pane
specified in the forward declaration no matter what I do.  Has anyone 
had
a similar issue?  How did you resolve it?

Currently I only see one way of doing it is to have a hidden form and 
have
my "Back" link submit that form.  That form would call a Turbine 
Action
that will do a Java ForwardService.forwardDynamic() call.  But that 
seems
a little excessive to me. I will also have to clear the js_peid from 
the
temp user storage....

Im also finding that putting the pane or peid in the session to track 
navigational state can be problematic.
Regarding your forwarding problem, I think it would be best if you sent 
me some sample PSML and your forward XML
I will then try to debug it
