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_thr... " - "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.
