Derive Classes/Objects Invisible: Why? [message #235466] Tue, 07 July 2009 05:20 Go to next message

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.

Hello Steven,

You have to add a constraint for NodeMapping of class A like: not self.oclIsKindOf(B)
