Hello everyone,

I am having a problem on testing a value on a many2many field on create() method.
I know that we should use:

         self.myfield_ids     : On write() method;
         vals['myfied_ids']  : On create() method;

I am trying to use "vals['myfield_ids']" on a many2many field and I am getting an "KeyError: 'myfield_ids'".
The code I have tried:

    if vals['myfield_ids']:
    returns: KeyError: 'myfield_ids'

How can I check if a many2many field is filled on form view for the create() method?
The field is not required on the form and I need to keep this way.

Thank you all in advance

Best regards

Paulo
