How to use the update query in google app engine while using with gwt. I'm trying to make a chat application where apart from submitting and deleting the previous messages, the administrator can edit out the portions of existing messages. For editing the existing messages update query is needed and I could not find anything like update query in data store. How can we update the existing data?
