[news.eclipse.modeling.gmf] Derive Classes/Objects Invisible: Why?

["Steven Punte" <steven.punte@xxxxxxxxxxxx>]

I have a simple situation of class B is derived from class A.

The Palette area shows tools for creating objects of both classes.

I can properly create on the canvas object of class A.

However, when creating objects of class B, they (they newely created object) 
disappear from the canvas.  After saving and closing the diagram and then 
reopenning it, the new class B object will appear at location <0,0>.

I have been looking in detail at the gmfgraph, gmftool, gmfmap files, but 
cannot identify a key difference.

Any Suggestions Appreciated.
