hi , its working on vaadin 7?
[code]

[/code]When implementing:
CAutoSuggest workOrderSuggestFld = new CAutoSuggest();
workOrderSuggestFld
.setResultsTableValues(new AutoSuggestResultsetBuilder() {
@Override
public List<AutoSuggestResultBean> getResultset() {
return myMethodReturnsAListOfAutoSuggestResultBean();
}
})This works currently, it’s not an addon, just customized a few classes. Would be really happy if someone could improve the code. By the way built with vaadin 6. Just change the listeners and I guess it’ll work for vaadin 7.

I’v been a problem with this component, when I use like this :
field.setValue(“Any value”)
The field stay empty.
anybody have this problems with this ?
