Martin Hubert commented on WICKET-2864:
---------------------------------------

Ok, thanks. With this workaround i can use FileUpload in a Wizard.

But I see some funny behavior.setFu is called twice when i press next. The first call sets a FileUpload object the second call sets NULL. The first call occurs before WizardStep.applyState() which seems to be correct, the second call occurs after applyState().
Other setters like setText1 are only called once before applyState().
