Hi all,
Just wanted to report that using a custom action <something:send> for an
XML namespace different than SCXML's default causes trouble. Specifically,
having the backing Action class implement ExternalContent causes problems.
The <something:send> element matches just like it is a normal
<scxml:send> element and the Digester rules barf--
java.lang.ClassCastException: org.apache.xerces.dom.ElementNSImpl
incompatible with org.apache.commons.scxml.model.ExternalContent^M

The offending Digester trace looks like

You can see where the org.apache.commons.scxml.model.Send class gets into
the mix. Not using 'send' as the localName of my custom action solved the
problem.
