ArrayCtrl::Paint is called three times [message #51686]

I'm just curious why ArrayCtrl::Paint is called three times when drawing the control?
Example: I just slightly modified reference/ArrayCtrl.

struct MyConvert : public Convert {
	Value Format(const Value& v) const {
		ValueArray va = v;
		RDUMP(va[1]);
		return String().Cat() << va[0] << " - " << va[1] << " - " << va[2];
	}
};

The log will contain THREE sets of data.
IMHO, this is a little bit too much from the performance point of view ...
