Seam Remoting/GWT1.5M2, change to 'Long' behavior (impacts Date?)
-----------------------------------------------------------------

                 Key: JBSEAM-2935
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2935
             Project: Seam
          Issue Type: Bug
          Components: GWT
    Affects Versions: 2.1.x
            Reporter: darren hartford


From: 1.5M2 announcement post -- http://groups.google.com/group/Google-Web-Toolkit-Contributors/browse_thread/thread/2f659fe351ff0b4c

"  - "long" emulation. The Java language defines "long" types to be 64-bit
signed integers, whereas JavaScript only supports 64-bit floating point
numbers, which cannot accurately represent the same whole-number range as a
true "long" type. GWT 1.5 M2 transparently emulates long types properly to
more faithfully maintain Java semantics in web mode. "

Although this is from GWT 1.5M2, the risk/return of them changing this is unlikely. It appears that this also impacts Dates.

This has been tested against Seam 2.1-snapshot (4/25/2008) and GWT 1.5M2 on jboss 4.2. Other datatypes are working correctly, Long and Dates are not.  This seems to only impact the RPC mechanism.



symptoms (on client side) for Long.  Same symptoms for java.util.Date:
