FileUploadField is always null if not in last WizardStep. 

public TestWizard() {
...
                model.add(new StepFu());
                model.add(new StepTxt());
...
}

works, but for 

public TestWizard() {
...
                model.add(new StepTxt());
                model.add(new StepFu());
...
}
the FileUpload ist always null.
