removeAllGraphics + addGraphic + dataChanged

I have a question regarding the dataChanged method on the AGSGraphicsLayer. My application removes all the graphics, then adds graphics one by one from a list, then calls dataChanged on the layer. Is it expected that dataChanged should pick up all the changes made to the layer? By that I mean, should I expect my old graphics to be removed and the new graphics added after the call to dataChanged? Or do I need to call dataChanged after I remove OR add graphics, each time?

The reason I ask is that something weird is going on and the single call to dataChanged doesn't refresh my map. If I change my code to look like this:

dataChanged;  // <-- Added extra call


The map will refresh properly. Odd, right? What's the expected behavior here?
