Datepicker: Input-field does not take locale into account

[leomayer]

Setting the datepicker with locale to e.g. de the date format changes from MM/DD/YY to DD/MM/YY.

I can type the date via the input field manually, e.g. 6th Dec 17 in 'de' ==> 06/12/17. When I change the input manually to 07/12/17 I get as a result in the calendar 12th Jul 17 - because date and months are switched.

Additionally (not directly related but nevertheless) I wanna ask if its not easy possible to add an Error check of the input - and assign it to a specific class (when the input fails to be converted to an appropriate date)

Since I know the input is a pain in the a** and the details get someone clz to nut I can provide some sample code as I did the conversion & checks (and validation of the input) - just as an inspiration...

  const val = this.internalDateString.trim();
    if (val) {
      let inValid = !moment(val, this.dateFormat, true).isValid();
      if (!inValid) {
        const test = moment(val, this.dateFormat, true).toDate();
        if (this.minDate && test < this.minDate) {
          inValid = true;
        } else if (this.maxDate && test > this.maxDate) {
          inValid = true;
        }
        if (!inValid) {
   // users input is a valid date (according to the format) ==> proceed....
          this.internalDate = test;
        }
      }
      this.isInValid = inValid; // used for hte bootstrap-class [has-error]
      // update the model
      this.onChange(this.internalDate);

Error check of the input - sure you can do any custom validation on input
Manual input parse is known and should be published next, there are similar issue to this one
