Hello @silverbacknet ,  
I’m having similar issues ([Attribute Error in Component Custom Method](http://forum.inductiveautomation.com/t/attribute-error-in-component-custom-method/47712)). I don’t mind passing a system argument…can you explain how I’d actually do that?  
Thank you and regards,  
Ted.
