I am having the same problem when using getInitialEventHandlerName() in
onRequestStart of one of my controllers. Has this not been resolved.
Should I just use, arguments.event.getValue(event.getValue("eventValue")) as
stated by Ezra?

The critical ingredient is getting off your
butt and doing something. It's as simple
as that. A lot of people have ideas, but
there are few who decide to do
something about them now. Not
tomorrow. Not next week. But today.
The true entrepreneur is a doer.
