问题
It was working before but then all of a sudden context sensitive help showing method names for example no long appear? What could have changed? I suppose if I create another workspace it will all work again but I hate to do that every time something like this happens.
If I do
myObject. // nothing appears here any more. It was working yesterday.
What Eclipse does is show an error on the line as I type it in.

I had this issue after updating my eclipse. This fix is fairly simple.
Window -> Preferences -> General -> Editors -> Text Editors
Change "When mouse moved into hover:" to Enrich Immediately & click Apply, OK.
