Frustrated that WebGUI::Form::Combo doesn't work in Thingy (it's not "dynamic compatible") I created a new WebGUI::Form element that supports item selection from a pre-defined list as well as free-text input. It's called WebGUI::Form::AutoComplete and it's a YAHOO.widget.AutoComplete powered form element that gracefully degrades into a plain old text input. I also added a skinnable trigger button a la the ExtJS AutoComplete widget.
