PostPaint Function undefined - CanvasExpress

Anonymous — Mon, 26 Jan 2026 16:26:21 GMT

Hi,

I am trying to create an extension using CanvasExpress (Javascript Charting Library), But I keep getting the ffg error message:

Can someone please help me with this, I have attached my Script.js, Definition.xml, and the canvasExpress Library.

Any help will be greatly appreciated....

Kind Regards

Razak

Here is a working sample. I diden't do much but I'm guessing you encountered our "definition.xml feature". We require that you drop a definition.xml file, should be exactly the same as in the root directory, for every sub-folder you include in your extensions.

Breakdown should look something like this:

ExtensionObjectFolder\

-Definition.xml

-Script.js

-Optional Files

ExtensionObjectFolder\js\

-Definition.xml

-JavaScript files

ExtensionObjectFolder\js\SubFolder\

-Definition.xml

etc etc
