That's a misleading exception... please create a Jira issue for
this. Here's the offending code:
protected void createAction() {
// load action
try {
action = (Action)
proxy.getConfig().getClazz().newInstance();
} catch (Exception e) {
throw new IllegalArgumentException("Unknown action name:
" + e.getMessage());
}
}
It's either an InstantiationException or an IllegalAccessException,
most likely, that's occurinig during newInstance()...
Make sure your Action has a public no-args constructor.

Any ideas why this exception can be happening?

Sounds weird, doesn't it? The first log message shows the action name, and then it's lost by the DefaultActionInvocation? How could I help you guys help me debug this, as a total WW2/XW1 newbie? :D
