Bug #202
Updated by Woozle Hypertwin almost 5 years ago
Tentatively, this is a "known bug":https://www.redmine.org/issues/25137 which has been fixed in 3.3.0 (we're on 3.2.1.stable).
Tentatively, the problem is conflicts that there can't be any "relationships" in "relationships" rules between
* a) either the task to be moved or any of its subsidiaries, AND
* b) the new parent (tentatively not the old one). subsidiaries.
It's not clear what the conflict is, because the error message never specifies (it just says "Parent task is invalid"). Sometimes a task with relationships can be moved, and sometimes it cannot.
*Workaround:* Workaround:
* Add a comment noting any "relationships" in the task (copy-paste works ok), then remove them.
* Repeat for all subsidiary tasks.
* If a task cannot be moved from parent X to parent Y even after "relationships" have been deleted:
** move it to the root first (no parent)
** then move it to task X
