[gwt-contrib] EntityProxyId
It's not very clear to me how EntityProxyId helps us achieve very simple scenarios. How do you use this thing when you have pre and post operations to do in an activity? If I have an edit scenario, let's say a user with a list of phones, normally, I would follow something like this: 1. Set the record in the activity 2. Start the activity 3. In start, get the id of the user and list the phones 4. When I receive the phone, I show the display of the edit activity I don't see how this is done anymore with EntityProxyId. How do I get my phone numbers? On the client side, the only member EntityProxyId has is getClass(), what I'm a suppose to give to the server to find my phone numbers? It's the same problem if you want to do something post save. If I want to save the phones of a newly created user, I would do: 1. Exit is called from AbstractProxyEditActivity 2. Save the user 3. Get the id of the newly created user 4. Attach the phone numbers to the newly created user Again, here, with EntityProxyId, I have no idea how you do this anymore. I don't mean to complain here but seriously how do you use this thing? It's so opaque that I can't do anything with it -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
