Hi Helmut, I have checked my lib-directory right now. I use my myfaces-api-1.1.2.jar and myfaces-impl-1.1.2.jar. So I think that I use MyFaces version 1.1.2.
I have solved my problem in such a way that I still get this error message, but trying the file upload for the second time, there comes no error message and the file upload works. Gr.
