Thank you Gordon,
That worked great. I guess I wasnt too clear on what I wanted but you
nailed it. I was trying to add myUIComponent.i = i without extending the
UIComponent in a subclass. I came to the same conclusion by appending the
vars to an existing property already there and realized I had to do it
your way. I was doing this at one point myUIComponent.name = i.toString();
and I could see it coming back.
Thanks you so much.. saved me many more hours of foolishness.
