Model of a simple graph structure
SUMMARY
Cannot create two aggregations between the same two classes. This is necessary
if modeling a graph structure, for example (see attached picture of what I am
trying to achieve).
STEPS TO REPRODUCE
1. Open a new class diagram, or use the default diagram;
2. Add two classes : Node and Edge;
3. Draw an aggregation from Edge to Node. Give it the role "source",
multiplicity 1..1
4. Try to draw another aggregation similar to the above with role "target"
OBSERVED RESULT
The second aggregation is not created.
EXPECTED RESULT
Multiple aggregations should be possible.
SOFTWARE/OS VERSIONS
Linux: Ubuntu 18.04.x
(available in About System)
Qt Version: 5
ADDITIONAL INFORMATION
There is an interesting comment in the method body of
"AssociationWidget::create()" which probably applies here. ;)
