How to handle click event on listBox
I have two listboxs. And I want to load The items into the second accordingly to the selected items in the first.And I want that the content of the second change each time the selected items of the first listbox are modified.
I don't know which event to handle for the first listBox indicating the items are selected in the first listbox. I want to execute the method loading items into the second listbox each time this event is fired.
Thanks in advance.

You can just use the 'onchange' attribute of the fist menu and put Javascript in it to submit the form on every menu change.<h:selectOneMenu onchange="this.form.submit();">
In the 2nd menu just check the current value of the 1st menu and then populate the list accordingly.

Thanks for your reply.
I used <webuijsf:listbox > component to display the list and .
And I want to allow user to select multiple items.
Then I want that the 2nd will be populated each time an item is selected.So the method doing it must be called in an action listener .
Please I don't really know how to use the <h:selectOneMenu> component.And I want that after the submit the 2nd list will be populated.
How can I do it please.
Thanks.
