After some tests with the quicklinkers and nesting connectors I came to the next problem.
Adding a any nesting connector to a quicklinkers profile seems not to work.
This definition doesn't work in EA 15.1 but works in EA 13.5:
Class,struct,Class,struct,,,,Nesting,,to,QuicklinkA,,TRUE,,TRUE,TRUE,,0,,,,,
Package,VC,Package,VC,,,,Nesting,,to,QuicklinkB,,TRUE,,TRUE,TRUE,,0,,,,,
The same definition with other cennector types works in EA 15.1 and EA 13.5:
Class,struct,Class,struct,,,,Association,,to,QuicklinkA,,TRUE,,TRUE,TRUE,,0,,,,,
Package,VC,Package,VC,,,,Dependency,,to,QuicklinkB,,TRUE,,TRUE,TRUE,,0,,,,,
So I guess there is a problem with nesting quicklinkers definition in EA 15.1.
