After debugging I saw that the UOE is thrown by the class org.hibernate.type.CollectionType, in the method replaceElements.

  | ...
  | java.util.Collection result = ( java.util.Collection ) target;
  | result.clear(); //just here
  | ...
  | 

When debugging I also saw that the collection is an ArrayList that has the correct value. I researched about possibles causes and it seems the most probable reason for this exception is that the ArrayList to be clear is unmodifiable, but I don't know why!

The debugging tells the exception is thrown by Hibernate, but it really does not involve it is the problem. Specially because hibernate libraries (bundled in seam) are the same in 1.3 and 1.2.1 version (so, nothing has changed), even I did upgrade to latest Hibernate libs and I got the same exception. 

I'm really stuck with this, hope someone can give me some hints regarding this, in the meantime I will go back to Seam 1.2.1, where all works fine (but I would like to use the upcoming 1.3).


Any help would be appreciated.

Thanks for your time.

If someone wants to see this problem running, as I said before I have a test case for JBoss 4.2.GA and tomcat 6.0.10.
