The bug! I want to decide it is own when and what I will to validate!

[optimistex]

I do setup option allowClear, but can't use it because the control becoming invalid when I have clear it.

ng2-select/src/select/select.ts

Lines 480 to 491 in 201c6e2

	public validate(c: FormControl): any {
	let controlValue = c ? c.value : [];
	if (!controlValue) {
	controlValue = [];
	}
	return (controlValue.length > 0) ? null : {
	ng2SelectEmptyError: {
	valid: false
	}
	};
	}
