I'm trying to use RichFaces <rich:fileUpload> component (with Seam as the overall framework) to upload a series of files.  However, when I click the "Add" button nothing happens.  Absolutely nothing.  I'm not prompted with an open dialog or anything.
I have a JSF page with an , and inside of that form I have:
<rich:fileUpload allowFlash="auto" id="contentImageUpload"
immediateUpload="true" maxFilesQuantity="5"
noDuplicate="true" required="true"
uploadData="#{contentSubmissionAction.contentImages}" />
The page renders fine, but when I click the "Add" button, nothing happens.  The #{contentSubmissionAction.contentImages} property is a List of UploadItem's, so I thought that was setup properly.  Has anyone seen this before?  Is there something in the configuration that I could be missing that could cause this?
