> 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"%>
> <%@ taglib uri="http://xmlns.oracle.com/adf/faces" prefix="af"%>
