1. Open an external C# file with File > Open File...
2. Put your cursor within a method.
3. Type 'this.'
4. NPE is thrown.

Interestingly, I am not able to open an external c# file => instead of a file a tab with the message "error" is opened (like it is a file)

is the error
So you see on line 219, we call editorFile.getProject(), on an external C# file, the editor isn't editing an IFile, so it is null
what is the error you are getting?
--
this method calls are necessary, to get the project settings which src dirs are set
to get the base classes for distinct objects
hm, this is coupled to project settings at the moment, the basis for code completion
an option would be, to decouple e.g. the gac from projects and let the project add additional source files

Dominik, you might want to look at the OpenExternalFileAction class and see why you can't open external C# files. That bug should have been fixed in 0.3.

Dominik, are you still unable to open external C# files?

Unfortunately not; I am using a Target Platform pointing at 3.3.1.1

External C# files should now be openable on 3.3.1.1.
