negative remaining_hours in project_task

[jugglefish]

As soon as the effectivly done work on a task in hours exceeds the planned hours I'd expect the delay_hours to reflect that situation. However instead the remaining_hours will further decreased turning into a negative number.

steps to reproduce:
1. create a task with 0-X planned hours (0 to see the effect straight away)
2. do some work on the task (less then X)
3. see remaining hours decrease
4. Up to now: everything fine
5. do some work so the effective hours exceed the plannend hours(X)
6. Remaining hours turn negative

how to fix:
* IMO reamining_hours must never be less than 0
* when saving the work and recalculation is done remaining hours should only be lowered to minimum 0

project/project.py
class project_work(osv.osv)
def write
 cr.execute('update project_task set remaining_hours=remaining_hours - %s + (%s) where id=%s', (vals.get('hours',0.0), work.hours, work.task_id.id))

Hello Amit,

If the task is linked with a project, the indicators of the project are wrong.
On the project view, the time spent and total time of the project are =0...

Thanks

Hello,

Tested on Version 6.1 RC1.

Create a new project.

Create a first task linked with this project :
 - planned hours = 10
 - add a task work for 3 hours
 - save the task -> Total hours = 10 , Remainning hours =7 OK

Create a second task linked with the previous project
 - planned hours = 0
 - add a task work for 3 hours
 - save the task -> Total hours = 0 , Remainning hours =-3
This second task is used to historize the customers extra requests appeared during the project and not planned at the beginning. I wonder if there is another way to manage this

Go to Reporting>Tasks>Tasks analysis
-total and planned hours =10
-Effective hours = 6
-Remainning hours = 4 !!!!!! instead of 7
