Using highcharts in sencha touch - Can't render empty chart - highcharts

Question

i'm trying to port some highchart charts from a php web appplication to a Sencha Touche mobile app.
I want to put an empty chart in my View page and populate it dinamycally with some jsonp calls.
Here's my view code (not all the 130 lines...):
{
xtype : 'panel',
scrollable: true,
html : 'INSERIRE QUI I GRAFICI E LE TABELLE',
items : [
{
xtype : 'panel',
layout : 'fit',
html : 'AREA PER GRAFICO',
itemId : 'chartRenderPanel',
margin: '180px'
},
{ //sample code, to be replaced with a consinstent config...
xtype: 'highchart',
chartConfig: {
chart: {
type: 'spline'
},
title: {
text: 'A simple graph'
},
xAxis: {
plotLines: [{
color: '#FF0000',
width: 5,
value: 'mar'
}]
}
}
},
{
xtype : 'panel',
layout : 'fit',
html : 'AREA PER TABELLE',
itemId : 'tableRenderPanel',
margin: '180px'
}
]
}
The Highchart part is taken from this fiddle http://jsfiddle.net/marcme/DmsGx/
it works on the fiddle but not in my mobile app: debugging with chrome, i get stuck here in the Highcharts.js:
update : function(delay) {
var cdelay = delay || this.updateDelay;
if(!this.updateTask) {
this.updateTask = new Ext.util.DelayedTask(this.draw, this);
}
this.updateTask.delay(cdelay);
},
With "Uncaught TypeError: undefined is not a function " message in the console.
Please, help! : )

You have to call DelayedTask differently in sencha touch than you do in Extjs. Change this
this.updateTask = new Ext.util.DelayedTask(this.draw, this);
to this
if (Ext.util.DelayedTask)
this.updateTask = new Ext.util.DelayedTask(this.draw, this);
else
this.updateTask = Ext.create('Ext.util.DelayedTask', this.draw, this);
