Content Assist Error

Jun 30, 2009 4:53 AM

While using Flash Builder 4 beta things will be working fine and then all of a sudden I get a popup error saying:

"Content Assist" did not complete normally. Please see the log for more information.

java.lang.NullPointerException

I'm not sure where the log file is, but if I restart Eclipse (i.e. Flash Builder) things will work again, for a little while, then the error comes back.

Any ideas?

Hi,

I have this error too. In my case it helps to remove and add the Flas SDK 4 to the project. Unfortunately this error message is thrown every 30 seconds, so I have to set the SDK all the time instead of do some coding.

The result is I use FB3.

@Adobe guys: any ideas?

Regards,
Christoph

Interesting, I'll have to try that.

My work around is to use IntelliJ IDEA....I'm trying to hold hope for Flash Builder (which is why I'm trying the Beta)...but IntelliJ is working really well so far (and it naturally supports Maven, unlike Flash Builder unless you install m2eclipse...although Flex Mojos support is supposed to be in a future version of m2eclipse).

The log file is in your workspace/.metadata/.log. You can also access it in the UI at:

Help > About Eclipse Platform > Configuration Details > View Error Log

If you can find the error message still, please file a bug. Thanks!

Same error for me and all the members of my team.
In particular cases, it keeps throwing me the null pointer exception while using content assist via CTRL+Space.

This is really annoying my Flex 4 development. Is there a workaround?

Have you seen this error in Beta 2? If so, please file a bug with a reproducable case. In some cases though, a clean workspace fixes the problem. Not the best workaround, but it's worth a try.

What I really meant to say is, please add your comments and workspace log to this bug http://bugs.adobe.com/jira/browse/FB-21566.

It's been a tough one to track down, it doesn't happen for everyone. Any additional info you can provide would be great: project type, SDK version (and build number if you're using a nightly), file type, and library path would all be helpful here.

Any libraries on your library path? If you're willing/able, please send us your project as an FXP or your workspace .metadata folder for the log and Eclipse/FB caches.

Are any of you using subclipse for versioning? Maybe that is the problem...
On the project I am using subclipse I have this error. On another project where I am not using subclipse I do not have the error.
Anyway... any suggestion would be very very appreaciated!
thank you

Repeating on the bug comments and on the beta forum...

PLEASE try a clean workspace. In detail:

1) Export the project as an FXP from the workspace that has the problem
2) File > Switch Workspace > Other..., choose a new, empty folder
3) Import the FXP
4) Try code hints

We have in the past seen problems with workspace caches. If we can rule this out, it would help us a lot. I'm trying my best to reproduce the issue, but with no success. The error indicates that a class in your project has no ancestor project...which normally isn't possible unless a cache has gone bad. Again, I need more help since I can't reproduce this. Thanks guys.

A more surgical workaround that allows you to keep your workspace settings:

1) Quit FB
2) Delete this folder: .metadata\.plugins\com.adobe.flexbuilder.codemodel
3) Restart FB

Cleaning out the caches works for most people, but others are still reporting the same issues after the workarounds. We're continuing to track this bug here http://bugs.adobe.com/jira/browse/FB-21566.

It seems that the following:

"Delete this folder: .metadata\.plugins\com.adobe.flexbuilder.codemodel"

is the current workaround.

Can someone point me to where that folder is on OSX? I've dug and dug, and removed similar folders, but nothing fixes the issue.

Thanks in advance...

if you want to solve this problem.
you have to have a well operated workspace....
(i have several workspaces one of them is broken some of them are working well)

all you need to do is copy the folder in well working workspace. (.metadata/.plugins/com.adobe.flexbuilder.codemodel)
and then paste in to current workspace you were working on...

try and hit me back if you have any question~!

Every time I export a new swc from Flash I get this error. I don't have to replace any files in the .metadata, I just reboot Flash Builder. Anyone else having this problem?
