[Developers] Graph dateline is older than last write

[Augusto Callejas]

hi-

i was performing a mqlwrite operation:

=====
{
  "qname" : {
    "query" : {
      "create" : "unless_exists",
      "id" : null,
      "name" : "billy",
      "type" : "/user/augusto/default_domain/type1"
    }
  }
}
=====

and got this error:

=====
{
 "code" : "/api/status/error",
 "messages" : [
   {
     "code" : "/api/status/error/mql/unknown",
     "info" : {
       "dateline" : "9202a8c04000641f800000000852713a",
       "write_dateline" : "9202a8c04000641f8000000008558f91"
     },
     "message" : "Graph dateline is older than last write",
     "path" : null,
     "query" : "read cost=\"\" dateline=\"\"
id=\"cache;cache01.sandbox.sfo1:8101;2008-06-02T23:45:46Z;0003\"
(typeguid=9202a8c04000641f8000000000000002
left=9202a8c04000641f8000000000000001 comparator=\"octet\" datatype=string
pagesize=201 result=((value left right)))"
   }
 ]
}
=====

i was curious what this means.

thanks,
augusto.
