Scott M Stark updated JBAS-5211:
--------------------------------

    Attachment: jsf-facelets-jbas5.jar

The facelets jar was hacked by Ales to include the following two source changes/additions. For CR1 there needs to be a proper patch made and incorporated into a new facelets. We have asked the seam team to track this.
