I don't like unanswered questions, so i'll answer it myself. It was actually a style-inheritence problem.
My implementention had a lil' bug. But because of style inheritence, it seemed to work fine in the first context i used the component in. But using it in a second environment, the bug occoured. So: beware of style ineritence :) --- In [email protected], "florian.salihovic" <florian.saliho...@...> wrote: > > I have noticed a strange behaviour regarding the ToolTipMananger.
