Interesting this is that when i put those g files into new project, everything works fine, seems just some project specific setting(s) deny to use antlr editor/build ?

    Hi,

    I cannot reproduce it. Are you sure the .g file is in the Project?
    ANTLR IDE doesn't have full support for external files, that's the *.g file must be in one Eclipse Project.
    I tried to open a .g file from my Ubuntu Desktop and I found the same error that you describe, this new release allow you open and view the grammar content in the Outline View but nothing more.

    Let me know if this works for you.

    Thanks,

    edgar
