ChangedEvent not triggered for mouse right click DELETE

[BharathiRajendran]

Hi,
I have a textitem in my dynamic form for which I use a ChangedHandler to enable/disable the form based on the input.

Here is the piece of code:

TradeIdTextItem().addChangedHandler(new ChangedHandler() {
	public void onChanged(ChangedEvent event) {
	if(event.getValue() != null) 
            {
	if(event.getValue().toString().matches("[0-9]*,*[0-9]*")) 
                 disableSearchForm();
             else 
                 SC.say(presentationMsgs.numericValueForId());
	}
	else if (display.getTradeIdTextItem().getDisplayValue().isEmpty())
		enableSearchForm();
             }
	});

Issue:
When I enter any value either by typing or copy pasting using ctrl c and ctrl V or Mouse roght click copy and paste, the Onchanged Event is triggered.

Similarly when I press backspace/ delete buttons or mouse right click CUT, or CTRL X the changed Event triggers.

But when I mouse right click DELETE , even though the value is deleted from my textitem the changed Event is not triggered.

Am using smart gwt 2.2, gwt 2.0.3, IE 6 , Windows XP 2002 SP2, DEV Mode

Did any of you encounter the same issue? Please post your findings. Thanks.
