Uncaught TypeError: Cannot call method 'getFullYear'

Uncaught TypeError: Cannot call method ‘getFullYear’ of undefined

Everytime I try and add a task.


Arqiva Activity Tracker
<script src="/codebase/dhtmlx.js" type="text/javascript" ></script>
<script src="/codebase/dhtmlxgantt.js" type="text/javascript" charset="utf-8"></script>

<style type="text/css">
	html, body{ height:100%; padding:0px; margin:0px; overflow: hidden;}
	gantt.config.xml_date = "%Y-%m-%d %H:%i"; 
	gantt.config.scale_unit = "month";
	gantt.config.date_scale = "%F, %Y";
	gantt.config.scale_height = 50;

	gantt.config.subscales = [
		{unit:"day", step:1, date:"%j %M %Y" }

	//var dp=new dataProcessor("php/data.php");   


Try the recent build of the component from this post
does the issue happens there?

That worked fine. No more errors in the log or chrome javascript console.

Many Thanks
