                 Key: JBSEAM-2546
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2546
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.1.CR2
            Reporter: Dan Allen
         Assigned To: Dan Allen
            Priority: Minor
             Fix For: 2.1.0.GA
         Attachments: JBSEAM-2546-v1.txt

There is an inconsistency between the native JSF parser and Seam's Interpolator, which is used to resolve page descriptions in the pages.xml file, amongst other places.

If you need to place a # character just before the value binding expression, you must escape with with a backslash (\) according to the EL specification (i.e. \##{contextVariable}). However, the Interpolator chokes when it encounters this syntax.

The Interpolator should be changed to ignore a # sign if escaped.
