Marvin Monroe commented on JBSEAM-3984:
---------------------------------------

just fyi, I had the same problem and it simply went away when I added this to the components.xml:

	<core:init jndi-pattern="MyApp/#{ejbName}/local">
		<core:interceptors>
			<value>org.jboss.seam.persistence.ManagedEntityInterceptor</value>
		</core:interceptors>
	</core:init>
