Dear all!

I am getting following error message:
"Found interface com.google.gwt.user.client.Element, but class was
expected"

when doing something like:
myWidget.getElement().getStyle().setOpacity(0);

where myWidget has been just attached to the doc a few LoC before.

it is not reproducible, it seems that it happens only in DevMode but
not even always...

what does the error message mean?

thanks
Michael
