Bug Description

Have tasks:
 -> B

1, Swtich to WorkView -> only B is shown
2, Drag B and drop it somewhere

Expected result:
Nothing change.

Actual result:
The relation between A and B is discarded and A is also shown in WorkView.

The same issue can be reproduced when filtering with a tag.

Hi Izidor,
   I am unable to understand the bug.
   When we drag drop B into some other task, B becomes a child of that bug and A looses that child. Hence A is shown in workview. Isn't that the expected result?

Nimit> when you drag B somewhere but not under another task. For instance, you start dragging B under C but then you would like to not do it. You put it somewhere else (white space). Expected result is that nothing happens (B is still under A). Actual result is that B is put as standalone task -- something I wouldn't expect in WorkView.

I disable drag and drop for all the views apart from 'All tasks'. Implemented a 'remove_dnd_name()' in liblarch.

Hi, I don't agree with your patch adding remove_dnd_name(). I still want to be able to drag tasks under another one. Disabling DnD does not solve the root of the problem.

Ideal solution would be to have a check before moving if any of task parents are visible in the current view and task is moved to the root. Psuedo code:

parent_shown = any(parent in tree.get_nodes()for parent in node.get_parents())
is_moved_to_root = ...
if is_moved_to_root and not parent_shown:
