Ended up with this:
public class ClearFormComponentWizardStep extends WizardStep {
public ClearFormComponentWizardStep(String pTitleMessageKey) {
this(pTitleMessageKey, new Model<String>(""));
}
public ClearFormComponentWizardStep(String pTitleMessageKey, IModel<?
extends Serializable> pModel) {
super(pTitleMessageKey, pModel);
}
@Override
public Component getView(String pId, Component pParent, IWizard
pWizard) {
WebMarkupContainer view = (WebMarkupContainer)
super.getView(pId, pParent,
pWizard);
if(isTimeToClear()) {
clearAllFormComponent(view);
}
return view;
}
/**
* Can be overriden for changing the clearAllForm behavior
*
* @param pView
*/
protected void clearAllFormComponent(WebMarkupContainer pView) {
pView.visitChildren(FormComponent.class, new
Component.IVisitor<FormComponent<?>>() {
@Override
public Object component(FormComponent<?>
pFormComponent) {
pFormComponent.clearInput();
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});
}
/**
* Override this if any other parameter would affect
clearAllFormComponentCode
*
* @return
*/
protected boolean isTimeToClear() {
return true;
}
}
