[umbrello] [Bug 446020] Bird's eye view shows nothing at first open

https://bugs.kde.org/show_bug.cgi?id=446020

--- Comment #2 from Robert Hairgrove <[email protected]> ---
When running Umbrello as a debug build started from a terminal, after examining
the debug output, it seems that the problem here arises from the fact that the
default configuration gives us an empty class diagram which can immediately be
populated with classes, packages, etc. However, the debug output "view was
NULL" on opening the application with no other command-line options seems to
indicate that this initial diagram was not yet added to the diagram/view stack
... even though there is a "class_diagram" object present in the tree view?
This would certainly explain the fact that there cannot already be a bird's eye
view of a view that (officially) does not yet exist.

Is this a configurable option? Why doesn't the inital screen show an emty
diagram area (dock widget) instead? I would think that with a new project,
where there is no code as yet in existence (and perhaps the programming
language is not yet determined), it might make more sense to have either no
diagram, or else perhaps a use case diagram, presented to the user.

At any rate, if there is a valid diagram, there should also be a valid bird's
eye view.
