I have 2 one2many fields in different models.

models A contain project(project.project) and o2m fields that contain employee assigned to that project.

I want to copy that records to other o2m fields with onchange event .

Ex :

on models A , i have project 001 that have employee X,Y and Z

on models B , if i choose project 001 and click save , i want o2m fields on models B show employee X,Y, and Z

Thanks
