Are you saying initialize the property-pointer in the class GA's
constructor?
I just wanted to get a working example ;)
I tried this, I am on windows vc2003.net, but that still doesnot compile.
I've
switched to using local variable instead(although more local definitions,
but
easier to get it work anyway)
Maybe we can get Doug (the one who made the Bundled Properties) to
comment on this...
Cheers,

Simplified sample as follows, produced the error.
