How Greater statement of Pyson works with a functional numeric field?

[Jesús Martín Jiménez]

Hi,

I'm trying to set a domain in a M2O field depending on the value of a functional field that is a numeric field this way [1]. But, depending how I define the ZERO constant, I get different tracebacks [2] and [3]. Could somebody tell me what I'm doing wrong?

Thanks,

[1]
        domain=[
            If(
                Or(
                    And(
                        Eval('type') == 'out',
                        Greater(Eval('total_amount', ZERO), ZERO)),
                    And(
                        Eval('type') == 'in',
                        Less(Eval('total_amount', ZERO), ZERO))),
            ('kind', '=', 'receivable'),
            ('kind', '=', 'payable')),
            ],

Using 0.0 or 0 works for me.

PYSON doesn't support Decimal.

PYSON doesn't support Decimal.

Do you mean I cannot compare a Numeric field with Pyson statements?
