Hi,
Right_connection and left_connection members of the UMLAttribute
structure are not available from bindings.
The connections are available on the object level, getting the one matching
a specific attribute is possible already, although more difficult than your
approach. See attached pydia sample.
Here is a patch which allows to access to these connection points with
pydia.
The patch looks basically right on the implementation level to me. But I
didn't apply it yet. Bad things would of course happen, if the
connectionpoint property would be set. But you rightly do not implement that.
But on the design level I wonder if the extra convenience your patch offers
really justifies all the extra complexity.
In attachement, test.py is an example of use.
Comments are welcome :)
Thanks,
Hans
