I think that List inherits a 'length' property. If that's the case, it should have been documented, and the getLength() method should not have been documented. In general, we're trying to make Flex property-centric whenever possible. Future releases are likely to deprecate support for accessor methods like getLength().

There is an error in the doc - getLength() should have been listed as a method of List.

And if you check the List it is said that it does NOT extend DataSelector. And there is no getLength method. And still you can use List.getLength which is internally implemented by DataSelector. Simon: I think so too, but my whole point was that you cannot be sure, since it is not said anywhere. And technically speaking list based components cannot implement DataSelector since DataSelector is not an interface but a class. And I know they doesn't extend it either. If there's someone from Flex documentation team listening, could you tell, if this issue is explained somewhere?
