angular2 and zingchart Uncaught (in promise) in lable/node_click - charts

Question

I am using zingchart in my angular2 application and came a cross this problem.
when I am trying to click the node - I get:
angular2.dev.js:23730 EXCEPTION: Error: Uncaught (in promise): TypeError: Cannot read property 'parentNode' of null
when I try to do that same when I am in debug mode - i.e. do it slower when jumping from line to line everything works fine.
I read a lot about about the Uncaught (in promise): TypeError: here and tried some solutions but with no luck.
Maybe anyone have an idea for me?
Thanks
I have a pie chart:
Which have the following code:
render(){
this.zone.runOutsideAngular(() => {
zingchart.render({
id : this.chart['id'],
data : this.chart['data'],
width : this.chart['width'],
height: this.chart['height']
});
zingchart.node_click = function(p) {
window.location.href = #/resources";
}
});}
my resource component is very simple:
import { Component } from 'angular2/core';
#Component({
selector: 'resources-component',
templateUrl: `I am the resource page`,
})
export class ResourcesComponent {
title: string = 'resources';
constructor() {
}
}
