When I look at the “cascading” relationship in a process decomposition, the Inspector shows me what I expect: an “owning/owns” relationship between parent and “child” element.
However, in EA I do not find that relationship back in the “links” part of the parent element, probably because no explicit relationship was established, the relationship was implied by the hierarchical structure in the browser.
What puzzles me most is that (a) in EASheet, there are “children” relationships reported, uinstead of “owning” relationships, (b) this is ONLY done FOR THE FIRST LEVEL while (c) 2 empty children columns appear.
