wantOnSelectionChangedNotifications causing table redraw

[salmas <ss...@ecascabel.com>]

I have a DataTable in which I have a panel which contains a textfield and a
radiogroup. When the user changes the selection in the radiogroup I'd like
to populate a value in the textfield. I subclassesed RadioGroup to catch the
selectionChangedEvent

RadioGroup choice = new RadioGroup(workflowFrame_radioPanel_radioGroup,new
Model()){
	protected void onSelectionChanged(java.lang.Object newSelection) {
            //Figure out what is selected and set value in textfield
	}
			
	 protected boolean wantOnSelectionChangedNotifications() { 
	   return true; 
	} 
};

As soon as I override the wantOnSelectionChangedNotifications method I get
the notifications but the table is redrawn as soon as the user selects an
option in the radiogroup while if I do not override this method the UI does
not do this ugly redraw when the user toggles the selection in the
radiogroup. I am using AJAX to redraw my table in other instances so that
the table redraw is smooth. Is there any way I can catch the selection
changed event and have the table not redraw? I can redraw it myself with an
AJAX target after I set the value in the textfield.

Re: wantOnSelectionChangedNotifications causing table redraw

Instead of using wantOnSelectionChangedNotifications you could add an 
AjaxEventBehavior or AjaxFormSubmitBehavior on "onchange", depending on 
whether you want the form to be processed or not.
wantOnSelectionChangedNotifications is a bit strange in that it uses 
normal javascript to submit the form the formcomponent is in.

I'd rather have that onSelectionChanged would be called _any_ which way 
the form was submitted, be it javascript (wantOSCN), normal submit or 
ajax. Would this be the same then as onModelChanged?
