Question

我遇到了一个似乎已在这里解决的问题。我想在示例here中使用订单列表。但它根本不起作用。我在示例中列出了<p:ajax>的顺序列表。

即，我有一个错误：

javax.servlet.ServletException：/resources/abc/rankingAnswer.xhtml @ 21,85 <p:ajax>无法将行为附加到非ClientBehaviorHolder父级

我在pom.xml中的Primefaces配置是

        <!-- prime faces -->
    <primefaces.version>5.1</primefaces.version>
    <primefaces.themes.version>1.0.10</primefaces.themes.version>

我的观点是

                <p:ajax event="reorder" listener="#{cc.attrs.question.onReorder}" />
                <p:column>
                    <h:outputText value="#{answer.text}" />

            </p:orderList>

我的模特是

public class RankingQuestionDTO extends AbstractQuestionDTO implements Serializable {

    private ArrayList<RankingAnswerDTO> possibleAnswers;
    private boolean randomizeAnswers;
    private String text;

    public RankingQuestionDTO() {
        super(QuestionType.RANKING);
        this.text = MessageUtils.getBundle("survey.default.text");
        this.possibleAnswers = new ArrayList<>();
        this.possibleAnswers.add(new RankingAnswerDTO(MessageUtils.getBundle("survey.default.text")));
        this.possibleAnswers.add(new RankingAnswerDTO(MessageUtils.getBundle("survey.default.text")));
        this.randomizeAnswers = true;
    }

    public void onSelect(SelectEvent event) {
        System.out.print(event.getObject().toString());
    }

    public void onUnselect(UnselectEvent event) {
        System.out.print(event.getObject().toString());
    }

    public void onReorder() {

    }


    public void addEmptyPossibleAnswer()
    {
        this.possibleAnswers.add(new RankingAnswerDTO(MessageUtils.getBundle("survey.default.text")));
    }

    public ArrayList<RankingAnswerDTO> getPossibleAnswers() {
        return possibleAnswers;
    }


    public String getText() {
        return text;
    }

    public void setPossibleAnswers(ArrayList<RankingAnswerDTO> possibleAnswers) {
        this.possibleAnswers = possibleAnswers;
    }

    public void setRandomizeAnswers(boolean randomizeAnswers) {
        this.randomizeAnswers = randomizeAnswers;
    }

    public boolean getRandomizeAnswers() {
        return randomizeAnswers;
    }

    public void setText(String text) {
        this.text = text;
    }
}
