Thank you Francois, but as I mentioned in an earlier post overriding FileUploadField#initModel() to return null did the trick and seems a bit cleaner that creating a Dummy model. Overriding initModel() makes sure the model won't be looked up in the component parents.

Hello, I'm having a problem with a FileUploadField, I'm using 
CompoundPropertyModels through my application but for this single element I 
would like to avoid having a model, however calling 
fileUploadField.setDefauiltModel(null) will not work, since it will always try 
to locate a CompoundPropertyModel, is there a way to avoid this?

Thanks in advance.
