Custom EL Functions in Facelets are not accessible in JSF through api calls
---------------------------------------------------------------------------

                 Key: JBSEAM-3494
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3494
             Project: Seam
          Issue Type: Feature Request
          Components: EL
    Affects Versions: 2.1.0.CR1, 2.0.3.CR1, 2.0.2.SP1
            Reporter: Samuel Mendenhall
            Priority: Minor

Custom Facelets EL functions define established through xml or a custom AbstractTagLibrary do not pass the barrier to JSF but are segregated purely to facelets.  So, one can't use Expressions.instance().createValueExpression(...) with a custom el function in it as it doesn't existing in the JSF FunctionMapper.

There should be some mechanism to either import the existing functions, or to register the functions with JSF alongside of Facelets.
