If no file is selected in a form with an s:uploadFile component, I get an NPE - new FileInputStream(null). Fix in the comment :)

public InputStream getInputStream()
 {
 if (bOut != null)
 {
 return new ByteArrayInputStream(bOut.toByteArray());
 }
 else // <---- fix: if (tempFile != null)
 {
 try
 {
 return new FileInputStream(tempFile);
 }
 catch (FileNotFoundException ex) { }
 }

 return null;
 }

Also, I cant build seam-ui from CVS at the moment, can someone commit their org.jboss.seam.ui.resource.WebResource :P (dependent class is SelectDate)
