[Marcos Didonet Del Fabro <marcos.didonet-del-fabro@xxxxxxxxxxxxxx>]

Hello!

The second part of the code has the good structure: you should first get the structural 
feature, then call an eGet() over the object passing the structural feature as parameter.

However, the "left" or "right" references are defined in the following way (in KM3):

	class Link extends WLink {
		
		-- @subsets end
		reference left container : WLinkEnd;
		
		-- @subsets end
		reference right container : WLinkEnd;
	}
	
	class LinkEnd extends WLinkEnd {
	}


These references "subsets" reference "end", but we do not define an opposite. Thus the 
"link" property is null, as you did.

To be able to access the parent link, you can use for example

wRightLinkEnd.eContainer();

This is an EMF method that returns the containing class.


Regards,

Marcos.
