Problem

Content Assist (Ctrl + Space) is not working in my Eclipse IDE version 3.3. I have two Eclipse IDE installed both in my laptop and home computer. However my laptop Eclipse 3.3′s content assist feature is working perfectly, the problem is my home computer Eclipse IDE content assist is not working at all? Everything i pressed a Ctrl + Space, Eclipse just show me nothing…it’s drive me crazy. How can such a killer feature disabled in my Eclipse IDE !!!?

I start googling online, this problem is happened since Eclipse IDE version 3.2, many people suffer and many solutions come out to quick fix on it. Sadly, there is no final solution for it, some may work with others some may not.

Solution

Here i summarize few solutions that may fix it.

1) Create a totally new workspace and import your existing project

P.S Remember check “Copy projects into workspace” to copy all your existing work to new workspace.

2) Go Preferences>Java>Editor>Content Assist>Advanced

P.S Make sure “Other Java Proposals” is ticked

3) Make sure (Ctrl + Space) is not hijacked by other application

My home computer (Ctrl + Space) is hijacked by Windows text input feature. I enabled Text Input with Chinese and English language, one of the text input key sequence is using (Ctrl + Space), it’s conflict with Eclipse.

4) Make sure regional and language options is in English
Control panel –> Region and language options –> Advance tab –> Language for non-unicode program –> Make sure English (United States) is selected, others may not work, no idea what may causing it.
