Cordova WP8 DatePickerPlugin callback not found

I am trying to use Lee Crossley's WP8 plugin-datetime-picker for the WP8 flavour of my Cordova app.

I already have iOS, Android and Fireos versions of the app running with their own datepicker plugins, but I'm struggling to get this version to work.

I instantiate the picker like so:

<input onclick="doDatePick(this)" readonly name="my-account-dob" id="my-account-dob" value="" class="required" />

And try to receive the input like this:

function doDatePick(elem) {
    console.log('at doDatePick');
    var onDateSelected = function (date) {
        console.log('inside function');
        alert(new Date(parseInt(date, 10)));
        console.log(new Date(parseInt(date, 10)));
        $(elem).val(DPgetNamedMonthDate(new Date(parseInt(date, 10))));
    }

    datetimepicker.selectDate(onDateSelected);
}

The datepicker is displayed, and 'at doDatePick' is logged. But when I confirm the new date in the datepicker, nothing else is logged and Visual Studio reports 'Failed to locate callback for id : DateTimePicker' in its output window. Needless to say, the input box isn't updated with my selected date.

I'm sure the Cordova project is set up correctly; I installed all the plugins I required and did a build before adding any code via Visual Studio. Other third party plugins, such as Chris Brody's SqlLite Plugin work fine.

Any advice greatly appreciated.

I have reported the core issue to the Cordova team.

As a temporary workaround, the platforms\wp8\cordovalib\Commands\BaseCommand.cs DetatchHandlers() method could be replaced with:

    public void DetachHandlers()
    {
        this.OnCommandResult = null;
        this.OnCustomScript = null;
        foreach (string callbackId in new List<string>(ResultHandlers.Keys))
        {
            if (!callbackId.ToLower().Contains("datetimepicker"))
            {
                RemoveResultHandler(callbackId);
            }
        }
    }

I know it's a hack, but it will get you going. You could alternatively use an older version of Cordova.

I have solved this issue on github.

No result handle issue

Simply I have saved the handler in selectDate method of DateTimePicker.cs class to read that back on ResultHandler dictionary before DispatchCommandResult.

public event EventHandler<PluginResult> mySavedHandler;
....
public void selectDate(string options)
{
    ....

    if (ResultHandlers.ContainsKey(CurrentCommandCallbackId))
    {
       mySavedHandler = ResultHandlers[CurrentCommandCallbackId];
    }
    ....
}

private void dateTimePickerTask_Completed(object sender, DateTimePickerTask.DateTimeResult e)
{
    ......
    try
    {
      if (!ResultHandlers.ContainsKey(CurrentCommandCallbackId))
      {
          ResultHandlers.Add(CurrentCommandCallbackId, mySavedHandler);
      }
      .....
      DispatchCommandResult(new PluginResult(PluginResult.Status.OK, result + ""));
    }
}
