Try using the attached RecursiveWizardModel. You give it a wizard model and
it
is prepared to handle a step returned from that model which is a child
wizard
model. The child wizard model is completely unaware of the enclosing model.
Some sample code:
public class RecursiveWizardTest extends WebPage {
private MyStep stepA;
private MyStep stepB;
private MyStep stepC;
private MyDynamicStep stepX;
private MyDynamicStep stepY;
private MyDynamicStep stepZ;
private WizardModel secondLevelModel;
private MyDynamicStep stepGroup;
public RecursiveWizardTest() {
stepA = new MyStep("a");
stepB = new MyStep("b");
stepC = new MyStep("c");
secondLevelModel = new WizardModel();
secondLevelModel.add(stepA);
secondLevelModel.add(stepB);
secondLevelModel.add(stepC);
stepX = new MyDynamicStep(null, "x");
stepY = new MyDynamicStep(stepX, "y");
stepGroup = new MyDynamicStep(stepY, "unused") {
public IWizardModel getWizardModel() {
return secondLevelModel;
}
};
stepZ = new MyDynamicStep(stepGroup, "z");
stepX.setNextStep(stepY);
stepY.setNextStep(stepGroup);
stepGroup.setNextStep(stepZ);
DynamicWizardModel topLevelModel = new
DynamicWizardModel(stepX);
topLevelModel.addListener(new IWizardModelListener() {
public void onFinish() {
setResponsePage(Completed.class);
}
public void onCancel() {
}
public void onActiveStepChanged(IWizardStep newStep) {
}
});
Wizard w = new Wizard("w", new
RecursiveWizardModel(topLevelModel));
add(w);
}
}
public class MyStep extends WizardStep {
public MyStep(String label) {
add(new Label("label", label));
}
}
public class MyDynamicStep extends DynamicWizardStep implements
IWizardStepGroup {
private IDynamicWizardStep nextStep;
public MyDynamicStep(IDynamicWizardStep previousStep, String label) {
super(previousStep);
add(new Label("label", label));
}
public boolean isNextAvailable() {
return nextStep != null;
}
public IDynamicWizardStep next() {
return nextStep;
}
public void setNextStep(IDynamicWizardStep nextStep) {
this.nextStep = nextStep;
}
public boolean isLastStep() {
return nextStep != null;
}
public IWizardModel getWizardModel() {
return null;
}
}
