I just downloaded the JBoss Portal Server 2.7.2 (JBoss Portal + JBoss AS 4.2.3 bundle to be precise) and tried deploying portlets just as the SimpleHelloWorld provided in the samples. The portlet gets deployed fine but when I put it on a page I get the following exception. I tried adding other Portlets as well (such as the booking MVC portelt supplied with Spring WebFlow dist) but the same problem happens.

The problem happens when the new instances are created by me, example when i create a new instance of CMS Portlet, I get the same error. If I use an existing instance it works. If I deploy a portlet that creates an instance using the "portle-instances.xml" then it works fine, but creating additional instances using the Admin and deploying them on page fails due to the following error.

What am I doing wrong? Can anyone please help?
