[jboss-user] [JBoss Portal] - Exception - No null layout allowed here

[explorer]

Hi all,
I am getting an exception 

java.lang.IllegalArgumentException: No null layout allowed here


I had been going through the forum for this exception but every one says that its related to MySQL5 Data Truncation Error.

But its not being handy to me.

My Envi:
Portal:2.6.1, 
AS: 4.2.1, 
DB: Oracle,
CMS: Alfresco,
OS : XP.

The full stack trace is
