Create two subtasks under an issue.
While on the issue list select both subtasks and delete.
Hierarchy is broken, lft and rgt fields have wrong values.

I will be available 24/7 regarding this issue as our company is trying to deploy redmine as a major tool and it is critical to maintain a stable environment.

Great project !

#1 Updated by Jean-Philippe Lang over 7 years ago

Using current trunk, I'm not able to reproduce. Selecting and deleting the 2 children properly updates parent's lft/rgt values.

#2 Updated by Contributor STUDEC about 7 years ago

We had the same problem with the 1.0.1 version of Redmine (we can not use the current trunk for now because of plugins compatibility).

We developed a patch to correct it. In the version 1.0.1 of Redmine, the children are deleted in the wrong order, ordering the "@issues" before the "destroy" of the issues_controller seems fix the problem.

Here is the patch developed by Studec. It is like a plugin, just copy/paste in the plugins directory (vendor/plugins).

Hope it will help.
