DataObjects are Flow elements inside Processes and thus should be referenced on their respective lanes when a process contains some.
However, they are often drawn outside the pool which results (from the designer perspective) in the objects not being dropable into the pool any more. (See attacked diagram).
- Fix drag / drop
- Or: Properly add dataobject to lane even when being created outside the lane.
- Or: Prevent dataobjects from being droped on "empty space" (ie. outside lanes) when lanes are present.
