Primary incident estimated duration not updated on form when adding task to WO

Hello,

When selecting a incident type, the tasks are automatically added to WO after saving. The msdyn_primaryincidentestimatedduration is calculated automatically with the sum of all tasks duration.

When removing a task, this field is automatically updated.

But when adding a task, this field is not udpated.

Does someone know something about this behaviour ?

Thanks

Julien
