Yes! I must see at least one a week here "Don't mix layout and non-layout panels."

If this is such a common mistake, does/should the tooling give warnings?

See http://code.google.com/p/google-web-toolkit/issues/detail?id=5874

The challenge here is to avoid false-positive warnings, when you add a layout panel (RequiresResize) to a non-layout-panel (ProvidesResize) but give it an explicit size.

There's also the issue of the HeaderPanel, which does not implement ProvidesResize yet provides it for its "center" child (but not for its header and footer children); which means that it would rather be the parent widget which should add the check for its children (HeaderPanel could check its "center" child but not its header and footer children, at its discretion).
