problem with onkeyup event version 4.0

see this link:
docs.dhtmlx.com/api__dhtmlxform_ … event.html

parameter value this returning undefined

I solved with getItemValue()

I’m only reporting the problem.

Hi
Can you reproduce this issue on local sample
dhtmlxForm/04_events/06_keyup_keydown_events.html
in version 4.0.3?
