swfupload-gwt not visible

[Ann Smith]

Hi
Has anybody succeeded in using this in a DialogBox?
I've been trying to get it work for couple of days and I'm about to give up.
I copied code from the project's getting started page, I build my swfupload
object in onLoad/show and I can see it attached to the page but for some
reason the upload button isn't visible.
I appreciate any tips.

experience with me.
Problem:

editor.edit(proxy,context) throws me ArrayOutOfBoundsException

Anyone has had it too?
