[Render Problem]

Hi , I am having a problem trying to render ChartFx 7 on Asp.Net

 The problem :

 On a control I have a Method Render with the next code

 chart.RenderFormat = ".NET"; chart.RenderControl(writer);

 When the page starts to render it throws me a javascript's error "Object Expected" .

It focus on the javascript method method "cfx_replace()"

I checked that the js is included .

I don't know how to solve this.

Waiting for an answer...
