please help me with this issue , I tried to fix it in the last 4 days with no success
I'm using the SelectItems DataBinder and it doesn't work
I am getting this Exception , please tell me what do I do wrong
the only differences betwen my EAR and the example EAR file of seam-selectitems that do work for me is the version of jboss-seam.jar(I'm using the newset - 1.0.1GA)
it seem to me that it does called the method fetchLanguges()(@factory method)
I tried to change the SB to be SF -> i am getting there a different exception
that says that the List doesn't contains Object instance of SelectItem.
