[news.eclipse.modeling.gmf] copy paste issue

[markitus <jxtamarc@xxxxxxxxx>]

Hi, 

I'm trying to copy and paste single elements from a model into a new 
model. Apparently it looks like it's done, since I can see a graphical 
copy of that element, but if I try to save the diagram and open it back 
it just disappears. 

any ideas?? this is starting to drive me crazy. I haven't been able to 
find any complete and clear example of a simple copy paste action on GMF. 
Many people has already asked this issue on this list before me but it 
seems like there aren't any convincing solution.

Please, help! 

thank you!
