I guess serializing objects and storing them in the history could work. However, there might be a mismatch in the Writer and Reader. GWT-RPC serialization to the server is a binary pipe delimited format, while the server returns optimized JSON. The GWT-RPC request looks something like this (... removes some data):
5|0|4|.../|8689529FF938331E041A0E722074DEF8|...|getCurrentUser|1|2|3|4|0| While the response look something like this: //OK[8,7,2,6,1,2,1,2,-1,2,6,5,4,1,3,1,2,1,2,1,[".../446307451","java .lang.Boolean/476441737","java.util.HashSet/1594477813",".../3836941791" ,"ROLE_ADMIN","java.lang.Integer/3438268394","..." ,"..."],0,5] So you might have to use your own format if the reader can't read what the writer makes. Nevertheless, depending on the size of your objects, the URL could get really messy. While we don't save the state of the object, we do use History to indicate "pages". We use a format similar to what Gmail does, i.e. mail.google.com/mail#label/gwt+group, etc. If we're editing a specific record, we use something like #edit/customer/425 so we have the unique id of the customer and just make a GWT-RPC to retrieve the record. I hope that helps.
