Redmine

A bit more information and probably not a defect, but a feature. The issue with the incorrect Due Date has a sub-issue. The due date on the sub-issue CAN be changed, it's just the parent issue that cannot be altered. You can delete the child issue, or remove the "Parent Task" hook to enable the Due Date field but it also removes the dates that were originally assigned. I would not expect "unhooking" two issues to remove the dates from the parent issue as well.

thanks.

I see the same issue on Redmine 1.2.1 (stable).
Shouldn't the parent issue due date be set to not earlier than the child issue due date? It makes little sense to have a later earlier due date if it's dependent on a child issue.

I agree that the parent issue should not have an earlier due date than the child issue. The problem(s) for me are:

1) a (new) child issue that blocks the parent issue from resolution might require the parent issue to have the due date change.

2) the parent issue loses it's dates if the child issue is detached (ie incorrectly attached or determined to be non-related).

Hope that helps.

This issue is still there in Redmine 2.5.0.stable. I sometimes can't change due date on a parent issue even if child issues do NOT have due date set.

This issue is likely due to corrupted lft / rgt nodes, so that the issue is not detected as a leaf. I am pretty sure there are concurrency or error handling issues around writing the lft / rgt values in the awesome_nested_set implementation, because these corruptions happen in our db every couple of months.
