Seam Messages strips any MessageFormat formatting parameters

                 Key: JBSEAM-2499
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2499
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.0.GA
            Reporter: Calvin Yu

I want to use f:outputFormat to format text so that I can specify the formatting style from resource bundles.

In messages.properties:

foo=Howdy {0}\!  The time is {1, date, MMMM dd}

In my Facelets view:

<h:outputFormat value="#{messages['foo']}">
  <f:param value="#{exampleAction.name}"/>
  <f:param value="#{exampleAction.date}"/>

The result of '#{messages['foo']}' is actually: Howdy {0}\!  The time is {1}

The reason this is happening is because the Interpolator is using MessageFormat to evaluate {1, date, MMMM dd} with empty parameters (line #141 in Interpolator.java), which results in just {1}.
