Error, when no value in colorPicker variable

[jhiemer]

Hi,
I had to add

    ngOnInit() {
      if (this.colorPicker) {
        let hsva = this.service.stringToHsva(this.colorPicker);
        if (hsva !== null) {
            this.colorPickerChange.emit(this.service.outputFormat(hsva, this.cpOutputFormat));
        }
      }
    }

to the directive, to get it going. Is this correct?

Hi,
The idea is provide a value, if you don't, you can use a empty string:
color: string= ''
and the default color will be #f00.

If the color is undefined would be something like this:
ngOnInit() {
if (!this.colorPicker) this.colorPicker = '';
let hsva = this.service.stringToHsva(this.colorPicker);
if (hsva !== null) {
this.colorPickerChange.emit(this.service.outputFormat(hsva, this.cpOutputFormat));
}
}

Well...in some cases the directive could be inside of a form and the value not defined yet.
I'm adding in the next update undefined variables and a new option for the default value when is not defined (now is #f00 when is a empty string).
