When I gave my first flexool build to Zoltan, he reported 2 erros and one of them was “TypeError: Error #1034: Type Coercion failed: cannot convert mx.utils::ObjectProxy@6380a19 to mx.collections.ArrayCollection”.
Not a familiar one for me. So I checked the engine I sent him on my machine. It was working fine without error. the i googled and found the reason behind this. It happens when there is only 1 single node in the xml flex is trying to load. So it is returned as an ObjectProxy instead of an Array and the error pops up. Perhaps a bug with flex.
