I am running Seam 2.0 Beta on JBoss 4.2.1. I have a category list as <s:selectItems/> values in an edit entity page. The problem is that in this page if I don't change the category selection I always get a "Not a valid value" error on the selection box when I submit. Even when I change the category selection and save the entity, I have to change the category the next time again to submit. Otherwise I still get the "Not a valid value" exception.
It doesn't seem that the category value of the entity is bound to the selection box, because when I load the edit page, the current category is not shown as a selected item.
The problem started after I upgraded from 1.2.1 to 2.0 beta.
