I have a Flex tree that gets its datatip from a function that returns an "@action" property from the XML node if it has one, otherwise an empty string. This works fine, except for when I'm expanding a group of nodes with one that has an action property in it. The tooltip pops up in the upper-left corner of the flex app, then if I move my mouse onto another item it will go away.
I'd like to know why it's doing this, and how I can stop it. (It also only happens the first time I expand a node.) I tried checking the activeEffects property of the tree to see if some "expanding" effect was in there I could check to skip on, but nothing.
