Creating a new seam project using Seam 2.0 and Redhat Dev Studio Beta 1 creates a Component.XML with the following error:

ERROR: 0.0 Unallowed child null:managed-persistence-context of components

The error shows in the tree view in the Redhat XML Editor and in the Problems tab as it causes a build error. Modifying the Component.xml file (adding in entity-manager-factory="" to the "persistence:managed-persistence-context" tag and saving causes the build error to go away but the error still shows on the Tree view tab. I removed the entity-manager-factory="" from the file and re-saved. Build still works. If I reopen the file in Tree view mode the build error returns.
