error in IE in DynamicForm on Del key pressed

[vantonov]

if in DynamicForm focus is situated on the field that doesnt handle Del key (in grid without editable fields, to be precise), on Del key pressed IE shows an error dialog (please see attachment - sorry for Russian, but it is "is null or not an object"). Ive tried to get that key press in form with addItemKeyPressHandler(), but it doesnt work

SmartGWT version 2.2, IE 8

Please show a standalone test case demonstrating the issue, and try it against a nightly build.
