Timepicker value doesn't get validated when there is a leading ZERO in the minute part

A timepicker form item marked as required seems to not get validated correctly when there is a leading ZERO in the minute part.

For example:

16:05 doesn’t get validated because the minute part starts with ZERO.

Hello Nikolai,

First of all, my apologies for the very late reply on this thread.

Regarding your question:

Do you still have an issue with the timepicker validation? If yes, could you share a configuration that reproduces it? I tested it with a minimal setup, and it seems to work correctly: DHTMLX Snippet Tool

The problem seems to appear when you have the valueFormat property in the configuration object:

const timePickerConfig = {
	type: "timepicker",
	name: "time",
	label: "Time",
	required: true,
	timeFormat: 24,
    editable: true,
	value: "16:05",
    valueFormat: "timeObject"
};

Hello @Nikolai_Dimentiev,

Thank you for clarification. It seems like built-in validation works inconsitetnly for this case. I already sent it to the dev team, and will notify you on any udpates.

Currently it can be avoided by custom validation, like follows:

const timePickerConfig2 = {
    type: "timepicker",
    name: "time2",
    label: "Time",
    required: true,
    timeFormat: 24,
    editable: true,
    valueFormat: "timeObject",
    validation: (value) => {
        if (value == null || value === "") return false;
        if (typeof value !== "object") return false;

        const hour = Number(value.hour);
        const minute = Number(value.minute);

        if (!Number.isInteger(hour) || !Number.isInteger(minute)) return false;
        if (hour < 0 || hour > 23) return false;
        if (minute < 0 || minute > 59) return false;

        if (hour === 0 && minute === 0) return false;

        return true;
    }
};
