Hi - I’ve been getting an error since upgrading to version 6.1 around qualifiers.
This is repeatable (on Linux and Windows) on a new project as follows:
1 - create a class diagram;
2 - create a class;
3 - create a second class with an association to the first;
4 - right click on the association and choose Role A → Qualifier…
5- hit the Add button.
Nothing visibly changes on screen, and no dialog appears to define a qualifier, but an exception (see attachment) appears on vp.log.
