[Sandbox] Alguém já usou?

Pessoal,

Alguém já utilizou o componente <s:inputSuggestAjax /> da biblioteca Sandbox, do MyFaces? Estou tentando utilizar mas não estou conseguindo, e o erro não me parece muito amigável. Tentei copiar exatamente o exemplo do site e mesmo assim não funciona. O erro que ocorre é este:

No arquivo template.xhtml, tenho o seguinte:

<s:inputSuggestAjax suggestedItemsMethod="#{produtoM.getSuggestItems}" value="#{produtoM.selectedValue}" />

Enquanto que no bean tenho o seguinte:

[code]private String selectedValue;

public String getSelectedValue() { return selectedValue; }
public void setSelectedValue( String selectedValue ) { this.selectedValue = selectedValue; }

[...]

public List getSuggestItems(String prefix) {
    List li = new ArrayList();

    li.add(prefix+1);
    li.add(prefix+2);
    li.add(prefix+3);

    return li;
}[/code]

Alguém saberia me ajudar? Obrigado desde já.
