Description
While making changes to Tracker's Find to use the Layout API, discovered a drawing bug when layout changes were triggered by a function in the overridden BWindow::MessageReceived hook.
The window calls DisableUpdates(), makes layout changes, and then calls EnableUpdates(), but the window is not redrawn correctly. Even adding UpdateIfNeeded() after EnableUpdates() did not cause the window to redraw.
Removing the calls to disable/enable updates allowed the window to redraw correctly.
My current changes are available at https://github.com/jessicah/haiku/tree/find-panel-layout-api, SwitchToTemplate.

Thanks for the report! I think there might be some code in place to support this, but my faint memory is that I never tested this very well and there might be situations, specifically moving around BViews, which circumvents the blocked updates. I.e. support for this feature is probably incomplete.
