Re: UnsupportedOperationException when using @WebFault with Aegis binding

[Zarar Siddiqi <za...@gmail.com>]

Has anyone looked into this? I'm pretty sure this is a bug which makes it
impossible to use an Aegis binding while using @WebFault.  As mentioned in
the original post this is happening because Node.class is not being checked
for in AegisDatabinding.createWriter().

Any ideas?
