The standard GWT RPC serialization for dates writes out the long value, so that
should be sent correctly. The error comes because when you convert that long to
a string, you do so in a particular timezone, and your choice of timezone can
change the day that you think this time point occurred
This is the reason we created the UTCDateBox. We only send a Long back
and forth between the client and server and that Long always
represents midnight in UTC. This avoids confusion when users in
different time zones are choosing dates.
You can see the UTCDateBox demo and source:

Hi dparish,
There are three issues here:
1. GWT needs a fully populated object graph to send back to the
client. Lazy fetching will not work across the client / server
boundary, so you must ensure that your code fetches all relations
eagerly (via an annotation or a separate call if needed).
2.

Hi Ahmed,
does your Member class contain associations to other classes? If yes,
I guess to have to repackage the lists as well... (i.e. create a new
Hashtable and so on). Another question could be if you can have
annotated classes on the client or you have to copy those classes as
well, i.e. have
