Connectors in models are not updated

[jez]

1. Create an own connector, draw a circle in icon view and a rectangle in diagram view
2. Create a model - "beta"
3. drag this connector to your model beta
4. Create model "gejma"
5. add beta component to gejma
6. Modify "beta" - i.e. add another connector
7. in "gejma" the block stays the same, even after save.

Only restart of OME helps - which is not simple, since you cannot use packages. You have to load all three models separately.
