Ajax for valueChangeListener

Question

I\'m using the p:ajax listener to handle value change events (because valueChangeListener is launched on form submit):

Answer 1

You could try the following:

1. Implement the value change event in your bean

    public void processValueChange(ValueChangeEvent e){
    //foo the bar
    }
   

2. Define a valueChangeListener on your selection component

   The key piece there is the submit() bit that processes the enclosing form on change of the value. You can then getNewValue() and getOldValue() as necessary.

EDIT: Now that I think about it, I see no reason why you cannot leave your setup as-is and simply define the valueChangeListener. It should still be processed during the change event in the , in fact, it will be processed before the listener for the ajax event itself.
