I am using jboss-eap-6.2, SEAM 2.3.1.Final, and RichFaces 4.5.4 Final.

A third party is POSTing a content-type “multipart/form-data” request to a jspx page in my web application.  Parameters are passed/injected through @RequestParameter to the page.  The request works when the content-type is “application/x-www-form-urlencoded”, but not when it is “multipart/form-data”.  I can see the correct content-type and content-length in the request object when it comes through, but am not able to access any of the parameters or attached file.  I’ve also programmatically built the multipart request to simulate what the third part is doing using Apache commons, but the outcome is the same.  This was working before an upgrade of JBoss, Seam, and RichFaces.

Also, the seam multi-part component is disabled in the components.xml with the following line: <web:multipart-filter disabled="true" />.  Removing it or changing it doesn't change anything.  The web application does use the rich:fileUpload on other pages which are sending multipart requests.  What else is there to multipart requests in this sort of setup?  Any Ideas?
