Accented Letters Problem (anchors, accents, ...)

I’ve created a font with a whole set of glyphs including anchors where applicable (top, bottom & _top, _bottom anchors).
However, when exporting the font the accented letters like é á and so on do not work.
Still all single glyphs (including accents) work on their own.

Any ideas or help how to fix this issue?

You need to actually build the diacritics, not just the separate letters and accents. See this video for details: http://vimeo.com/43551729 (especially at 1:37 and thereafter).
