RE: RE: modify association provider

GetInstance on $A1.More should return the instance of X aliased as $X1.

Hi George,

For instance, I have $A1 and I want to retrieved the Instances of $X1
with all properties besides the key ones.
I thought that was simple like X* inst = $A1->More, but is not enough.

I think I will try tomorrow:

Ref<Instance> ref = cimom::get_instance("root/cimv2", $A1->More);
X* inst = cast<X*>(ref.ptr());
