File upload doesn't work with PrimeFaces 4.0,

Question

I have a web application running on:

• Wildfly Beta 1
• JSF Mojarra 2.2.3 (from Wildfly)
• Primefaces 4.0
• rewrite-servlet-2.0.7.Final / rewrite-config-prettyfaces-2.0.7.Final
• commons-io-2.4 / commons-fileupload-1.3

And I have problem with file upload component (advanced and simple mode doesn't work, never print inside upload()).

Same is even run without rewrite-servlet-2.0.7.Final/rewrite-config-prettyfaces-2.0.7.Final libs.

My upload.xhtml file:

<h:form prependId="false" id="formLateralUpload" enctype="multipart/form-data">
    <h:panelGrid columns="1" cellpadding="5">
        <p:fileUpload mode="advanced" multiple="true" update="@widgetVar(msg)"
            fileUploadListener="#{test.upload}" auto="true" sizeLimit="10500000"/>
    </h:panelGrid>
</h:form>

My bean:

@ManagedBean(name = "test")
@ViewScoped
public class Test {
    private UploadedFile      file;

    public UploadedFile getFile() {
        return file;
    }

    public void setFile(UploadedFile file) {
        this.file = file;
    }

    public void upload(FileUploadEvent event) {
        System.out.println("inside upload()");
    }
}

web.xml:

Answer 1

I have the same issue with Wildfly 8.1, PrimeFaces 5.1, Pretty faces and file upload. There is a HACK to make this work in Tomcat, but I can't find one in undertow. PrettyFaces appears to be doing something bad to multipart post requests that prevents them from working correctly... They seem to be pushing it back to Undertow/Wildfly because the hack exists in Tomcat instead of fixing the actual issue.

Tomcat Hack: http://ocpsoft.org/support/topic/split-prettyfaces-anchor-with-primefaces-file-upload-not-working/

I'm road blocked on this and I can't really extract either PrettyFaces, PrimeFaces-Fileupload (I need background ajax/html5 uploading) or Wildfly... Anyone with a suggestion other than "use an iframe/simple mode" would be much appreciated.
