a4j and selectOneMenu's valueChangeListener
Hi all,
I'm just building an simple application that loads some items inside a selectOneMenu when a onblur event occurs in a inputText.So far everything is going well.
The problem starts when a try to add a valueChangeListener to the selectOneMenu and also add a a4j support linked to onChange event.
When I reproduce the onblur event for the second time OR when I change the combo value an java.util.NoSuchElementException is throwed.
Can you help me ?
Thats the cursed code ;-)
