RE: coming from .do file stops further template processing. Resolved!
Finally I found out what was the problem. I should not have used
return (mapping.findForward("view"));
in my Action-Klasse execute(). Instead I use NO view at all by simply:
return null;
And I just let the insert tag call the controller:
<tiles:insert page="/template/layout.jsp"
controllerUrl="/template/navigation.do" flush="false">
...
...
<tiles:put name"topnavi" value="/template/topnavi.jsp" type="page"/>
