[jboss-user] [JBoss Seam] - Help on s:filleupload

[xigua]

Hi, 

I am trying to use the fileupload component provided by Seam 1.1.6 and it worked if I actually select a file. The issue is that, if I didn't select any file, then I am getting NPE:

I am using InputStream in the managed-bean. 

Is there any way to make it work even if I didn't select any file?

Thanks,
