I've been attempting to construct a feed document with custom entries with =
no success. While I've seen some (very little) discussion on the web regard=
ing my error.

My code looks like:

ProfileElement profileElement =3D entry.addExtension(Constants.QNAME_PROFIL=
E);

And my error is:

"org.apache.abdera.parser.stax.FOMExtensibleElement cannot be cast to Profi=
leElement"

I can verify the configuration of my extension factory, and trace calls int=
o it.

this.addImpl(QNAME_PROFILE, ProfileElement.class);

The Getting Started Guide leads me to believe that "Extension Factories are=
 covered in detail in the Developer's Guide<developers.html>." However, tha=
t link is broken because the destination, developers.html, does not exist. =
 Can someone please help me resolve this exception and/or direct me to the =
referenced Developer's Guide?

Thanks
