I believe it's a bug in the compiler. It's non-sense to require an instance
when those are class-level instances.
However as a workaround you can use static fields. You can still initialize
them with class construct { } or static construct { }.
Also if you were thinking of overriding a protected class field, I hardly
believe that's implemented (there's a bug somewhere about that).On Sun, Sep 29, 2013 at 5:58 PM, Thomas Olson <tol...@stratagium.net> wrote: > > > Hello, > > This is the second time I've tried to post to the list, but I haven't seen > my first attempt show up in the vala-list archive yet, so I thought I would > resend, just in case. > > I'm still learning my way around vala so I may be doing something wrong, > but according to the docs at > https://wiki.gnome.org/Vala/**Manual/Classes<https://wiki.gnome.org/Vala/Manual/Classes> > : > > * Class members are shared between all instances of a class.
