NullPointerException when calling validation. [message #227516] Mon, 27 April 2009 11:28

Hello,

when I call the static ValidateAction.runValidation method of my generated
diagram-editor (not from within the generated editor), I sometimes get the
NPE below. Is there something I can do about it?

Thanks in advance,
Max
