Hi Leonid...
Well... i got this working with this:
// Pagina
<rich:comboBox value="#{controleAction.despesaSelecionada}"
suggestionValues="#{controleAction.valoresT}"
converter="conversorEnum" />
//Action.java
private TipoDespesa despesaSelecionada;
public List<TipoDespesa> getValoresT(){
List<TipoDespesa> valores = new ArrayList<TipoDespesa>();
for (TipoDespesa tipo : TipoDespesa.values()){
valores.add(tipo);
}
return valores;
}
//Converter using Seam... if using JSF, remove the notations and reference it on
faces-config.xml

Can't create combo box with list of enums
-----------------------------------------

I am trying to use a combo box, which would show the list of objects of the enum class,
but it throws the exception below as I open the page.
I am able to use to the same list for shuttle list though. Could anybody help?
