I have a lot of complex validations in my project. I just put the logic in my action method and add the appropriate messages to a map as feed it to the function below. If messages were added I redirect to the same page. This seems like an old fashioned what to do things, but I have not found a more JSF way to do this. If anyone has a better solution, please let me know. My validations are more complex than just inspecting the object to be persisted. I need to query the EntityManager to see if these changes are acceptable, not simply compare a few properties on an object. I also do not like to have to put required="true" in order to validate null fields. Is there any way around this? Could Seam be made to override the default JSF implementation behavior in this case? | public int addMessages(Map<String, String> m) | { | for(String key : m.keySet()) | { | if(key.startsWith("globalMessage")) | { | FacesMessages.instance().add(m.get(key)); | } | else | { | FacesMessages.instance().add(key, m.get(key)); | } | } | return m.size(); | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4013795#...
