I have an object "Operacion" that has inside an object "Entidad". I want to edit my Operation object.I want to change Entidad field in Operacion, so for this reason I have to press the botton. When I press the button I show a list of Entidad objects to select one of them. Then when I return to my page seam executes the update of Operaction always. I have done some test using properties like bypassUpdates but seam continues doing the update. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4058654#...
