You could use the event model provided by Seam. In the updateuser bean simply
raise an event:
...
| public void updateUser() {
| ...
| Events.instance().raiseEvent("userUpdated", user);
| }
| ...
Listen for that event in a method in your getusers component:
...
| @Observer("userUpdated")
| public void updateDataModel(User user) {
| // update the associated user in users2
| }
| ...
Another option if you don't want to pass the user that was updated through the
event, you could simply re-execute the factory method and use the @RaiseEvent
annotation on the updateUser() method. Hope that helps.
