Wicket Wizard 在方法 isComplete() 中提供错误信息；

Question

除了之外，我正在尝试自己实现带有步骤概述的 Wicket 向导。现在的问题是，isComplete(); 似乎 return 正确，即使该步骤尚未完成。我完成了 3 个向导步骤 然后我是运行这个代码：

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);
    }
}

第一步在控制台的输出是：

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

关于下一步的改变：

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

关于最后一步：

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 post 中所建议的那样，如果它最终起作用，我想分享这个组件。提前致谢。

问题是我执行的步骤还没有真正的目标吗？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()的含义并不是你想的那样：

/**
 * 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();

注意 "if the wizard can proceed to the next step"。
