Hi Loïc

you can add an @api.onchange or @api.depends on you method, that handle if the field is visible and unset the value if the condition are not met

example

field_is_visible = fields.Boolean()

my_field = fields.Text()

@api.depends('field_x1','field_x1' ) 
def _check_visibility(self):
    for rec in self:
	​	​if #your condition:
	​	​	​rec.field_is_visible = true
	​	​else:
	​	​	​rec.field_is_visible = False
	​	​	rec.my_field = False # or '' depending on your fields type​

Hi Jainil, 

thanks for your answer. 

i understand that the framework does not offer an automated solution.

Hello Loic,

you have one field which is having some condition on which the field is being invisible, so on that condition you need to have an function which will make the field empty which will make the non needed value stored in the field thus you want to empty it. 

do i convey your need properly respond me so i can take you further with the solution.

Thanks
