one2many related field does not manage button action

[Давид]

Hello,

I have model A(view A) and Model B(view B)

Now in my model A, I have one2many model B.

Model B: fields, name(char), data(binary field), one2many(model C)

now from view A, I have one2many(Model B)

When I click on [add an item] it opens model b' view

With field name, data(binary field) and their is one button, on clock of it I import 'data' field's data to one2many field with modelC.

But due to record not saved, I can't add data in model C.

Also on button click It do not save record(one2many field(model B))

I receive traceback:
    res = self._obj.execute(query, params)
DataError: invalid input syntax for integer: "one2many_v_id_724"

Note: one2many field in form view does not work properly with button.
