Ahhh... I figured it out at last. There is somebody who put in ON ERROR DO Errtrap wihtout parameters in one of our form class. We have two form class actually: one for dialog boxes set as modal and one for regular forms set as modeless.

Thanks for giving me a hint.

ON ERROR DO ERRTRAP

Only this way can you get all .f. as parameter values in ERRTRAP program.
