When i started to use Eclipse's Content Assist, Eclipse used to give me Javadoc help of item i focus in a tooltip box next to content assist. However, after a while Javadoc tooltip stopped working. I tried resetting preferences to default but no luck. What should i do?
p.s: Javadoc works when i highlight an element (i.e. a method).
I mingled with various options for 4 hours...even created a new workspace. Finally what worked for me was some preference changes.
Goto Preferences > Java > Editor > Content Assist, click on Restore Defaults. Restart Eclipse and you are good to go.
