Only one label when multiple edges with same target mappings [message #1769425]

Dear,

I am sorry if this question is due to my lack of knowledge with meta-modeling and MDD in general. I am making a tool with which someone can make EER diagrams with UML notation for my master thesis. I have almost no experience with Java, so the professor that guides me decided that it would be a good idea to have me test if it is truly so that you don't need any programming experience to make use of the Sirius platform.

In my sample model, I should be able to define superclasses and subclasses and have them connected by a generalization edge. This generalization edge should then have only ONE label. This works as long as there is only one subclass.

Once there are multiple subclasses for one superclass, a label gets created for every subclass if I define the label under my edge style. This should not happen, only one label should be present that defines the generalization.

I have added an image of how it should look like, I hope that helps. I have also added all files which I created to create my diagram.

Thank you very much in advance.

Kind regards,
Sonny

Hi,

Unfortunately, it's not possible. In the image, there is not only one edge but several edges. For example, for Person superclass:
* One edge between Staff --> Person
* One edge between PrivateOwner --> Person
* One edge between Client --> Person

The layout, "tree layout", applied to these edge, draws a common segment to all edges but there are really 3 edges (and so 3 labels).

A solution is maybe to have a conditional style for the edges with only a label for the first sub class. I've not tested it.
