Hi colleagues)
I have a demand to use AutoComplete component.
So I download autocomplete.jar, put it in WEB-INF/lib, then create widgetset AutoCompleteWidgetset,
recomplile existing gwt.xml.
But after compilation there is no mention about new inherits like
“” in my gwt.xml.
And of course when i doing:

AutoCompleteTextField acEditor = new AutoCompleteTextField(); I got an exception((

What have i done wrong?

Does anyone know what to do that this functionality start to work?
