[jboss-user] [JBoss Seam] - Re: Issue when upgrading to Seam 1.3.0.ALPHA (CVS)

Use your debugger to find out. | 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!

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.
