[xwiki-users] Annotations on content in AppsWithinMinutes

I have developed a simple glossary app for my XWiki instance. Everything works great until I try to add an Annotation to the page, generally on content that is a TextArea type. As soon as I save the annotation, all of the fields of the app immediately disappear. They won't re-appear until I delete the Annotation. What am I missing? Does my TextArea have to somehow link to the AnnotationClass? Sorry if this is a newbie question; I'm just getting started with XWiki. David
