java - Wicket Wizard 在 isComplete() 方法中给出错误信息；

Question

除了 previous question ，我正在尝试自己实现带有步骤概述的 Wicket Wizard。现在的问题是，即使该步骤尚未完成，isComplete(); 似乎也会返回 true。我执行了 3 个向导步骤，然后运行以下代码:

public class MainWizard extends Wizard{
    private static final long serialVersionUID = 1L;
    private List<IWizardStep> steps = new ArrayList<IWizardStep>();
    private Component overview = newOverviewBar("overview");
    private IWizardModel wizardModel;

    public MainWizard(String id, IWizardModel wizardModel, boolean addDefaultCssStyle) {
        super(id, wizardModel, addDefaultCssStyle);
        this.wizardModel = wizardModel;
        fillList();
        getIndex();
        this.add(overview);
    }

    public void getIndex(){
        for(IWizardStep step : steps){
            System.out.println(step.getClass());
            if(step.equals(wizardModel.getActiveStep())){
                System.out.println("Active");
            } else if(!step.isComplete()){
                System.out.println("Pending");
            } else if(step.isComplete()){
                System.out.println("Finished");
            }
        }
    }

    public void fillList(){
        Iterator<IWizardStep> iterator = wizardModel.stepIterator();
        while(iterator.hasNext()){
            steps.add(iterator.next());
        }   
    }

    @Override
    public void onActiveStepChanged(IWizardStep newStep) {
        try{
            getIndex();
        } catch (Exception e){
            e.getMessage();
        }
        super.onActiveStepChanged(newStep);
    }
}

第一步控制台的输出是:

class {package}.StepOne > Active
class {package}.StepTwo > Finished
class {package}.StepThree > Finished

更改到下一步:

class {package}.StepOne > Finished
class {package}.StepTwo > Active
class {package}.StepThree > Finished

最后一步:

class {package}.StepOne > Finished
class {package}.StepTwo > Finished
class {package}.StepThree > Active

我无法解释这种行为。正如我在上面链接的帖子中建议的那样，如果它最终有效，我想分享这个组件。提前致谢。

我实现的步骤还没有真正的目标，这是一个问题吗？我是否必须手动设置 setComplete(); 或面板代码中的任何内容？

Answer 1

IWizardStep#isComplete()的含义不是你想象的那样:

/**
 * Checks if this step is complete. This method should return {@code true} if the wizard can
 * proceed to the next step.
 * 
 * @return {@code true} if the wizard can proceed from this step, {@code false} otherwise.
 */
boolean isComplete();

记下“向导是否可以继续下一步”。
