Forget it. we were testing different versions. The one with Oracle really had the problem, but it was in our code. We were modifying an attribute in a node, not by calling the api to modify the attribute, but the api to modify the whole node, which seems it wasn't updating the node in database. We changed to update only the attribute, and now it's stored in database. Sorry for being a lammer. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112212#...
