I am correcting an issue I previously created (#21457), which is more a feature request than a defect (and was not really clear)

Let's say I have the following issue statuses:

!calculated_from_subtasks_actual.PNG!

And

!activity_confirmed.PNG!

And any other status has a % Done associated to it.

Redmine is set to compute the parent task % Done based on subtasks, and it is working well:

!parent_task_ok.PNG!

Now, let's say I mistakenly changed the status of the parent task manually to "Activity confirmed_0%":

!parent_task_ok_2.PNG!

So now the % Done on the parent task is not calculated from subtasks, and this is perfecly normal.

But now, I want to correct my mistake, and put back the status to "Calculated from Subtasks":

!parent_task_ko.PNG!

Again, the result we get is normal. Redmine just keeps track of the old % done associated, as if the task was On Hold.

h2. Feature Request

In Issues statuses new/edit form, add a checkbox which appears when % done selected is blank, and which allows, when checked, to "Erase" the previously affected % done on the issue, so we can start again to get a % done computed from subtasks.

Something like that:

!request.PNG!

So checking this box would allow me to get the behavior I expect:

!parent_task_ok.PNG!

Thanks for the good work!
