UML: classes swapped when creating association and assigning cardinalities
When initially creating an association between classes a and b, assigning cardinalities of a-1--b results in a--1-b. The cause for this probably is that the classes order differs from getting created to getting edited. For example, when creating an association by selecting class a first and then class b, class a is displayed on the right in the cardinalities pop up. However, when saving the cardinalities and selecting the association again, class a is displayed on the left but the assigned cardinalities keep their positions.
