Mark related items for removal when "parent" item is marked for removal

[Jari Häkkinen]

When a transformation is deleted in the analysis view the created files and directories are not marked for deletion. One would expect these to be deleted similarly to existing removal of a whole sub-tree with a simple select and delete action.

No, anything created by a transformation is softly linked using AnyToAny links. The links can actually lead to any kind of item, not just files and directories. It is not possible to automatically delete the items that are linked in this way.

Could this be a part of explaining ticket:1147?

[Nicklas Nordborg]

I think I was wrong about this one. I was thinking about the actual deletion of the items from the trashcan, but the ticket obviously was about marking the items for removal. The RemovableUtil class already has functionality were this could go into. I guess the same problems applies to files attached to bioassay sets and extra values (see #1050).
