Ok the problem is that somehow you are holding on to a FileUpload in your
page
And those are not meant to be kept over requests.
it seems that you keep it if i read it right in a normal Model:
[class=org.apache.wicket.model.Model]
private java.io.Serializable
org.apache.wicket.model.Model.object
[class=org.apache.wicket.markup.html.form.upload.FileUpload]
How do you create the FileUploadField?
I guess with a normal new Model()?
I think we need to fix that somehow in the detach of the FUF because if the
model is set
we should look into the model and if it is a FileUpload get rid of it or
something.
