Hello, i am used to use HibernateManagedEntity. Both classes HibernateManagedEntity and ManagedEntity are renamed. Please refer to this thread: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=92311 We have to wait. There will be an example which shows how to use the refectored (renamed ) ManagedEntity. I wanted to try this out and asked here in the forum. The above link shows gavins answer. Ciao, Carsten View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3976942#...
