I've got an object that descends from List, and uses an itemRenderer. Recently, I tried adding datatips to it, but nothing shows up. When I set it to use a datatipFunction, the function never gets called.
If, however, I remove the itemRenderer, datatips show up properly. Has anybody seen this sort of thing before? (Note: the ItemRenderer creates two objects, but neither one short-circuits mouse events or have datatip info of their own)
