Re: native type of gdd object

Thanks,

It was it. In fact I tried that casPV::bestExternalType () and it didn't
work as it suppose to.
And reason for that was that this function must be defined as const, and in
my case it wasn't, so it
wasn't overloaded properly. May be it will be interesting for others ..
