Predict Connections - limiting allowed connections or BeforeConnection type even

 Predict Connections - limiting allowed connections or BeforeConnection type even

I am currently trying to figure this out as well.  Does
anyone have any ideas?  To be more specific I have 2-D
shapes and 1-D connectors.  I want connectors to be able
to connect to any 2-D shape but not any other 1-D shape.  

Right now if the user tries to connect two connectors to
the same 1-D shape at the same connection point it
sometimes makes the new connection between the two
connectors instead of between the connector and the 2-D

Andrew - How did you disconnect the shapes in code?  I
have tried moving the shape slightly away but it still
remembers the connection.
