如何从jsp检索String []数组以使用Struts2进行操作？

Question

I've some logic problem with Struts2, i'm trying to pass an array of Strings from jsp to an Action, the problem is that, when i try to pass this Strings in an ArrayList it goes well, i can see datas, when i try with the same names and values, to pass the value into a String[], the value it's just null, where i'm doing wrong?

That's my Action:

 public class EscludiElementoRicercaMagazzinoAction extends MyActionSupport {
    /**
     * 
     */
    private static final long serialVersionUID = 7627908677897902673L;
    private static Logger                   logger              =           Logger.getLogger(EscludiElementoRicercaMagazzinoAction.class);
    String[] selezionato;



    public String[] getSelezionato() {
        return selezionato;
    }




    public void setSelezionato(String[] selezionato) {
        this.selezionato = selezionato;
    }



    @Override
    public String execute() throws Exception {
        logger.debug("inizio");
        //TODO DA FINIRE
        MovimentazioneMagazzino.escludiMagazzino(selezionato);
        logger.debug("fine");
        return SUCCESS;
    }
}

And that's how i send data to action...

<input type="hidden" value="54" name="selezionato[0]" class="hiddenModaleEscludiElemento">

Just remove the index in your input like this:

<input type="hidden" value="54" name="selezionato" class="hiddenModaleEscludiElemento">

Hope this would help.
