[Vtigercrm-developers] extend/override Vtiger_Import_Js

[Alan Lord]

This doesn't appear to be a normal Vtiger Class type Javascript library 
but I want to change it's behaviour under certain circumstances.

How do I extend / override it?

I don't see how the normal

 > Parent_Class_Js("My_Inherited_Class",

construct would work with this file.

Maybe I have to make a complete copy of the file, rename it, load it via 
a HEADERSCRIPT actionlink and change the url in the button to 
instantiate it?

TIA
