Re: How to use RequestFactory: .with(propertyRefs) for composition of objects

Hi there:

Assuming that your lists are named listB, listC, listD, then you would
write:
.with ("A.listB", "A.listB.listC", "A.listB.listC.listD")
to cause your various proxies to be populated by a single call to the
server.

Hope that helps,
Ryan
