Error: 'this' is only defined in non-static member functions, not parse

I will try to remove all snippets in my code that aren't relevant but still
exhibit the issue, when I find the time. What I forgot to mention is that
this error appeared when I did some so-called "refactoring"; I moved a
nested class out of its parent, since I wanted it visible on the outside.
I moved it back now and reference it by Parent.Child.<stuff>, which is
just as good, and the error isn't there anymore, but I still don't understand
it. I must have missed some variable renaming or something. Or I was
just plain sloppy. As mentioned I will post a complete snippet with the
error sometime until friday.
