Cut/copy/paste no longer work after vertex id fixes #87

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Steps to reproduce:
  1. Create a simple graph.
  2. Copy and paste a region with edges.
  3. Save and close the graph.
  4. Reopen the graph file.
  5. Notice how all the edges of the pasted region are connected to the original copied vertices.

Basically, when a union is performed, vertices need to be assigned new ids.  
The problem now lies in the serialization of the vertices, as the newly pasted 
vertices have the same ids as the copied ones.
