FileUpload: NPE in org.richfaces.renderkit.html.images.ColorUtils
-----------------------------------------------------------------

                 Key: RF-2403
                 URL: http://jira.jboss.com/jira/browse/RF-2403
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.0
         Environment: JDK 6u4, RF 3.2.0CR1, Facelets 1.1.14, JBossAS 4.2.2, JSF RI 1.2_08 
            Reporter: Juergen Zimmermann


When invoking a JSF page with <rich:fileUpload> I get a NPE in the JBoss console with the stacktrace below.

 Looking at  http://anonsvn.jboss.org/repos/richfaces/trunk/ui/progressBAR/src/main/java/org/richfaces/renderkit/html/images I'd recommend for the methode ColorUtils.adjustLightness() to test whether the object c is null. Just the same as in method overwriteAlpha.
