I'm seeing the following:

When I initialize my diagram file from the model, I see my nodes and
connections and all is fine, but looking at the diagram file, I only
have the notation:Diagram, and after a restart of eclipse, the diagram
will open empty and not show anything until I drop a node, and save, and
only then I have children in the diagram file and it appears to open
correctly from then on.

Why would the initial initialize not persist the diagram children
information until the diagram is changed and saved?

I would appreciate any input.

diagram_no_children.diagram is the initial diagram created from the
wizard, no changes or saves, opens empty after eclipse restart...

diagram_children.diagram is file after a move and save...

Thanks
Brian Jakubik

Hello Brian,

It was done intentionally - diagram content should be re-created again by
the update procedd on next openning. You can modify something on a diagram
(move a node) to make everything persisted into the diagram file.

The problem with empty diagram on eclipse openning was introduced recently
by a constraints specified for ViewProvider. We have to modify these constraints
to correct this problem.
There is bugzilla entry for this task. M.b. we will fix this problem even
in 2.2.1 bugfix.

The entry mentioned by Alex seems to be https://bugs.eclipse.org/281014
