How can I remove / clear items out of a list control in Flex?

I have a list control in Flex that has been data bound to an e4x xml object from an HTTPService.

I would now like to have a button that clears the list, how can I do this?

I have tried:

list.dataProvider = null;

which does not seem to work, I have also tried:

list.dataProvider = {};

which clears the items but leaves [object,object] as the first item in the list...



list.dataProvider = new Array();
