Java Content Assist automatically inserts nonsens [message #1748468]

I like content assist, as a quick way to help me remember method/variable names, etc. But when using the content assist of Eclipse, it frequently inserts garbage when pressing space or '.'. For example, when typing 'i' followed by space, it automatically inserts 'isCorridor' (a method of my class), even though a local variable 'i' is also defined. I have tried different settings for Content Assist, but they do not seem to do anything, or switch off content assist altogether.

How do I prevent this behaviour?

I would like the content assist popup to come up, but it only to insert anything when I press TAB (or RETURN), and then only the common prefix of all suggestions. That, together with the option to select a specific suggestion from the list would work satisfactory.

Ideally, the common prefix of all the suggestions would be inserted already (in a different color) in the text, such that you type over it, and it would be accepted when pressing TAB.

If it makes a difference, I am using Eclipse 2.0.1 for Java on MacOS.

Hello Rene,

Eclipse 2.0.1? really?
The latest version is 4.6.1, so if it is really the correct version a lot of things might have changed since that time (several years ago)

Another possible cause is simply that the variable is not visible in the scope you are trying to use it. Can you double-check that the variable you are trying to use is in the correct scope?

Thanks for your answer, Aurelien.
I'm running an update now, but it tells me that the latest version available for the Eclipse Java IDE is 2.0.2. How do I install the newer version?

The variable is in scope, and it is in the list of options, but at the bottom. But that is actually not the main point: I want to avoid the automatic insertion of a suggestion when typing space. Is there a way to switch that off?

Your version is too old to have an automatic update to the latest one.
You need to download a newer one from http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/neon1a Depending on your OS, you need to choose the correct lin at the right.
To Install the, just unzip and launch the executable.

For the space issue, it doesn't work like that with newer version, you should not have this issue.

I have now installed the latest Eclipse (Neon.1a Release (4.6.1)), and that seems to run fine. However, I still have the same issue with content assist: pressing space still inserts a content assist suggestion. Do I need to change some settings to prevent that?

Thanks,
René

Hello René,

Do you have a single proposal in your case?
If yes, there is an option "Insert single proposals automatically" that you can deactivate in Windows->Preferences then Java -> Editor ->Content Assist

You can also choose to enable/disable or change time before auto-activation of the completion on the same page.

I hope that you will be able to configure as you wish from these preferences.

It's not a single proposal in most cases, and the option you mention was already switched off.
And if I switch off auto-activation, then the proposals don't come up at all. I would like to still see the proposals automatically, and be able to choose one with arrow keys and RETURN / TAB. I would just like to get rid of the auto-insertion when I press SPACE or '.'.
But I guess I will have to live with that?
