"Could not create the view" error

[danceboogie8]

Hey everyone,

I'm new to Flash Builder and have been following a tutorial video to learn the basics. Today, when I tried to access my project, this error appeared in the Package Explorer:

Could not create the view: Plug-in "com.adobe.flexbuilder.as.editor" was unable to instantiate class "com.adobe.flexbuilder.as.editor.ui.packageexplorer.FlexPackageExplorer".

I also can't seem to create a new Flex project. If I try to, I can never click Finish. The button just remains faded out.

Below are the details on the package explorer error.

Any help would be much appreciated.

Thanks.

[MiroSabo]

I have the same problem/error, but no one seems to know what's wrong. No reply from Adobe Support either. Same project works with FB 4 and 4.6, but not with 4.7.

Hi Miro,

I'm having the same issue on FB 4.7 command line.

Did you manage to resolve/analyze it?

Also, it seems that this error is related to this one:

!MESSAGE An error occurred while automatically activating bundle com.adobe.flexbuilder.codemodel (29).

org.osgi.framework.BundleException: Exception in com.adobe.flexbuilder.codemodel.CMCoreActivator.start() of bundle com.adobe.flexbuilder.codemodel.

Any ideas?

Thanks,

Erez.

I'm having this issue since ever with FB 4.7 (the normal IDE version, not the command-line one).

The most consistent way I found to resolve it is to delete the output folders of all flex projects, then restart and perform a clean build.

My suspect is that the incremental compilation is flawed, but cannot be sure of it.

P.S. usually the initial error has this root exception

Root exception:

java.lang.NullPointerException

appears the air sdk is indeed not complete. So you need to overwrite the old sdk with the new one without deleting old, so that missing files would stay. I just don't understand why all the instructions say that you should delete the old one completely.
