Good afternoon, I'm having a problem with a one2many field in Odoo 15, I have two models hr.vacas.new and 'hr.vacas.new.fechas' , 'hr.vacas.new' has a computed field with a @api.depends decorator and has a value of 12 called 'x_dias_restantes'.

I have a one2many field called 'x_fechas' related to 'hr.vacas.new.fechas', when I modify the field, the value of 'x_dias_restantes' is modified.

Basically my problem is when I modify the one2many field, his write method is called, the write method check the value of 'x_dias_restantes', but when I introduce just one record, the value is 12 (correct), but if I introduce more than 1 record, the value is 0 always, and I don't know why, doesn't matter what values I introduce in the form, if there is more than one record in the one2many field, the value of 'x_dias_restantes' is 0 and should be 12.

If I introduce the data one by one, I mean, I add one record, press "save" and again and again, the value is correct, but if I introduce more than one at the same time, the value is 0.

Anyone could help me? Thanks!!
