Hello:


If the logic is contained in avalon components, you'd need to obtain 
them first (AFAIR cocoon.newInstance(MYCOMPONENT.ROLE)) and release them
afterwards. Remember to release components before creating a 
continuation, though.


I have a flow script:

       var facade = cocoon.getComponent( Packages.....ROLE );
        
        var cmd = cocoon.request.getParameter("cmd");
        
        if ( cmd == "soSomething" ) {
                doSomething( facade , form );
                form.finish("page/admin.xsp");
        } else {
                cocoon.sendPageAndWait("page/admin.xsp");     
        }
The Avalon component is a business facade which sends messages to the logic and delivers objects to the GUI. Where in this script do I have to realease the component (and how?) ?

And, by the way, is that a recommended approach?
OK, I'm not the local flow guru so take everything with a grain of
salt or jusk ask someone else ;-)
You should release components before a continuation is created, 
otherwise you risk a memory leak. There have been discussions on
doing it automatically, but AFAIR they were turned down because
of complexity.

A continuation is always created when sendPageAndWait is called, in
addition, you may create continuation explicitly.
Besides, the approach you describe seems perfect.
