I just put together a simple example, it works for me. What specifically what not working for either of you? If you just bind a @DataModel to a datatable with input components in your columns and place a submit button on the form with some trivial action (you can call em.flush() from the action if you like), the DataModel will get updated with your changes. Note, I am using a Seam Managed Persistence context, but an Extended PC would work as well. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064740#...
