It's exactly the same behaviour in my app. But I use Facelets(*.xhtml). The strange thing I found out: If I comment s:fileUpload tag, the fields are entered <!--s:fileUpload id="fileupload" data="#{specialreleaseeditor.file}" accept="*/*" fileName="#{specialreleaseeditor.fileName}" contentType="#{specialreleaseeditor.fileContentType}"/--> Without the comment the getter/setter of the fields file, fileName and fileContentType are not called in debug mode. Use Seam 1.2.1 and have configured the app as discriped. No exception is thrown. What can I do, get this working.
