Hello Alex,

first, thanks for your answer!

When i create a target end link constraint on the link mapping (i simply 
used 'self.getHash() > oppositeEnd.getHash()') in the gmfmap-model, it 
leads to being able to create a Neighbor-link from i.e. 'element1' to 
'element2', but not being able to create it from 'element2' to 'element1'.
At first, only one link is shown, but after open/close, both links are 
shown again.

Did i create the constraint at the wrong place? Does something like a 
"Display-constraint" exist in gmf?

Best regards,
Klaus
