Artwork won't display

Question

I got a copy of a syymbol pattern and am using the call below to create an instance centered in view.  Call comes back successfull but the symbol does not display in window.  I have the "paintOrder" flag set to kPlaceDefault.  Any ideas? 
error = sAISymbol->NewInstanceCenteredInView (symbolPattern, paintOrder, prep, &newArt );
error = sAISymbol->NewInstanceCenteredInView (symbolPattern, paintOrder, prep, &newArt );

Answer 1

Maybe my logic is wrong here.  Basically want to find symbol "QA Point" and place an instance in center of view.  I used sAISymbol->PasteSymbolPatternArt(symbolPattern) as you see below but artwork came in a group and not instance.  I commented it out and am trying to use sAISymbol->NewInstanceCenteredInView
for (i = 0; i < count; i++)
     error = sAISymbol->GetNthSymbolPattern (i, &symbolPattern, FALSE);
     error = sAISymbol->GetSymbolPatternName (symbolPattern, name);
     if (!strcmp(name.as_Platform().c_str(), "QA point"))
          break;
if (i < count)
     // error = sAISymbol->PasteSymbolPatternArt(symbolPattern);
     error = sAISymbol->GetSymbolPatternArt(symbolPattern, &prep);
     error = sAISymbol->NewInstanceCenteredInView (symbolPattern, paintOrder, prep, &newArt );
