conditionalExpression for greaterThan hits twice on input change with old value

[vytautas-pranskunas-]

Hello,

I am trying to implement greaterThan comparing two custom values and what i have noticed that validator is called twice: first time with latest value, second time with old value (and since old value is latest it leads to wrong validation)

my code:

static greaterThan = (fieldName: string, message = 'validators.greaterThenMsg') =>
        RxwebValidators.greaterThan({
            message,
            fieldName,
            conditionalExpression: (x: any, y: any) => {
                console.log(x);
                console.log(y);

                return false;
            },
        });

form

form: FormGroup = this.fb.group({
        timeFrom: ['', [Validator.required()]],
        timeTo: [
            '',
            [
                Validator.required(),
                Validator.customGreaterThan('timeFrom'),
            ],
        ],
    });

values received:

as you can see first call to validator (on value change) is with correct value and the second with previous one.

I have implemented custom Angular style validator and everything is going fine (so this is not an issue with change detection runing multiple times o not an issue with value bying set to old one somehow)
