Question

I have the page below, everything works fine…

Except that after I click the delete button and hit “Yes Sure” in the Confirm Dialog My page doesn’t change… It should show me the same form without that user.

I tryed a lot of things, but I am using Primefaces 3.0.M3
My form table is server created so it should be ajax usable.

Anyone got an idea what is wrong ?

Thanks !

Here is the controller method

public void deleteAction(String id){

    userFacade.remove(userFacade.find(Integer.parseInt(id)));

} 

This method is being called and it’s deleting the user.

Answer 1

You need to reload the allUsers list in the bean’s action method after deleting the user.

public void deleteAction(String userId) {
    userService.delete(Long.valueOf(userId));
    allUsers = userService.list();
}

Otherwise JSF will just retrieve the original list. You’re apparently prepopulating the list in the (post)constructor of a view scoped bean, that’s why a F5 works.
