I have a parent child self-association, let's say B (parent) <- A (child). For performance reasons, there is only one owner.
Now, in my OQL, I want to join some information of the siblings of a child. I use FROM A, JOIN B, which works perfectly.
However, I want to go from B to its children again. In SQL this should be no problem, since a join ON is based on a shared value between two rows in seperate tables. Mendix uses join based on references, which makes me dependent on the direction of the association.
How can I go from the child to its siblings, without making the reference owner 'both'?
