First call of date-time functions badly damaged

           Summary: First call of date-time functions badly damaged
           Product: XalanJ2
           Version: 2.4
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.lib
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: foxyshadis@hotmail.com


The first use of date-time functions seems to be badly screwed up on this
stylesheet. On other stylesheets it works, when used near the end; haven't yet
tried it on others near the beginning. Same results whether a date is passed in,
default param used, or datetime:date-time() substituted for $date in the function.

When head is commented out and title commented in, crashes with an NPE. When
both are in, title section works fine.

This worked fine in CVS early Dec or so.
