Aptana 3 intellisense/autocompletion stopped working

I am having a weird problem.

I had first installed Aptana Studio 3 and everything was working as it should have. But then suddenly the autocompletion stopped working. Earlier typing document.g would result in showing getElementById (and other methods with starting with g) but suddenly it stopped working. Finding no solution to the problem I installed the Aptana plugin for eclipse (3.0.3) and like before after sometime the autocompletion stopped working in eclipse too. Thinking it was some sort of bug I installed the preview release of aptana (3.0.4 beta) but that didn't solve the problem.

Instead of the normal methods (getElementById) I 开发者_运维技巧used to get earlier this is what I see now:

As mention earlier pressing document.g doesn't pops up anything (I tried ctrl + space):

In file association window (prefrences > General > Editors > File Associations) .js extension is set to JavaScript Source Editor. In Aptana Studio 2 this used to be Aptana JS editor.

So how do get it working again?

Try moving to a new workspace.. thats what worked for me.

its bug that was fixed but is still sporadic

I tried a few things like re-install but my workspace still had issue. It also may be something wrong with the files in workspace.
