Do you really want a different processing to be dependant on the portlet instance id? Surely your portlet code should depend on a portlet instance. Wouldn't it be better to add a property to your portlet and depending on the value of the property you have a different processing. That way you can create portlet instances with different processing. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4042755#...
