-------------------------------

      Summary: af:tree Need better error message for missing form tag  (was: Need better error message for missing form tag)
    Assign To: Adam Winer

Most components should do this correctly already;  af:tree is an exception, and is what is covered here.

> When an input component is used, but is not nested inside a <af:form> tag, ADF-Faces throws a NPE without any hint to the actual mistake.
> This situation should be detected, and an exception with a proper description should be thrown.
> Little issues like this one can cause hours of work for the beginning user like me or the other guy on the mailing list who posted this code:
> {code}
> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
