I don't think so since the NPE happens in org.jboss.seam.ui.FileUpload.decode
Maybe I misunderstood.
So I have a backing bean which has a InputSteam field and there are getter and
setter for it. So on the front end, I use <s:fileUpload
data="#{backingbean.filedata}" />. My understanding is that if user select the
file, then the file will be uploaded and set to the InputStream field otherwise
set it to null, I didn't try to read the file at all. It seems to me that once
I use fileUpload component and bind it to a field of the backing bean, the seam
component will try to read the file no matter whether there is file selected?
