Trying to extend the DocEmailTemplateAdvancedHandlerWFAL class but when I try and build the new class I get:
The class or interface ‘DocEmailTemplateAdvancedHandlerWFAL’ does not exist.
We can see that the class does exist but it is in italics. Our only option is to “Create code extension in new project” with class, is that what we need to do?
From the information you provided, I would suggest that you go in the direction of checking your model references. Our models extend the same way as standard Microsoft’s and other ISV models. Just make sure you follow the rules for extending it.
