Shopping Worlds Sample needed

I’m looking for a sample how can I add fields to my custom Shopping worlds element…   in EXTJS

There is a topic about this http://forum.shopware.com/discussion/18825/eigene-extjs-elemente-fuer-komponenten-erstellen/p1  

but the sample zip file is not available…

I have a problem with saving data…  and it looks like

**Shopware\_Controllers\_Widgets\_Emotion\_AddElement** is not triggered...
