[gwt-contrib] Editor framework and submitting object graphs
Hi, I've recently transitioned my web application from GWT 2.2 to 2.3 and I've started to encounter some problems. I have a few editors with multiple sub-editors that can be used to both create and edit resources. For example: Person [List Offices] [List Phones] [List Office Hours] This is constructed as a PersonEditor with a @UiField CompositeEditor for the offices and the CompositeEditor uses CellTable HasDataEditors for the phones and office hours. In GWT 2.2, this all worked perfectly, I can create a Person resource by submitting the object graph of sub-resources to the server and I can fetch a Person resource as well as all the sub-resources and the editor framework takes care of all the magic for me. In GWT 2.3, fetching works perfectly, but submitting does not. From what I can tell, the properties of any type controlled by a CompositeEditor are not filled in. This triggers javax.validation errors from my server which I can see on the wire. By putting breakpoints in the server, I am certain that the complete object graph is not sent. Since I'm unaware of any changes to the editor framework in GWT 2.3, other than renaming the request factory packages, I'm surprised that my editors are broken. Do you have any pointers? Thanks, -Tim -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
[gwt-contrib] Issue 6153
Hi GWT Devs, I've recently come across Issue 6153 (http://code.google.com/p/google-web-toolkit/issues/detail?id=6153) which affects the released version of GWT 2.3. Any chance of a patch or a release 2.3.1 to fix this? Automatic error reporting integrated with the editor framework is probably my favourite feature of GWT... it is shame to see it broken. Cheers, -Tim -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
[gwt-contrib] Domain type cannot be sent to client
Hi, I've been fiddling with the latest RequestFactory code in gwt trunk. I keep coming across the following error message: The domain type com.mtacit.rmddx.server.model.Email cannot be sent to the client. This occurs with quite a few of my domain types, in fact the domainToClientType map in RequestFactoryInterfaceValidator has only 4 entries when it should have about 25. If I understand the code correctly, the map is populated when requesting client types from the ReflectiveServiceLayer, usually via a request context method invocation. In my scenario, UserAccount has a List of Emails. The UserAccount domain type is in the map since it's proxy was referenced in an earlier request. However, because the Emails are in a collection on UserAccount, when the UserAccount proxy is validated (RequestFactoryInterfaceValidator::validateEntityProxy), the Emails are skipped. Now when I try to return a UserAccount object, including Emails, to the client, I get the above error. Is this a known issue and is there a workaround I can try?

Are the problematic types only reachable from the RequestFactory interface through a parameterized List or Set? Yes, that's the case. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: [gwt-contrib] JsonRequestProcessor and multiple findEntity calls
The behavior you're seeing is expected in the current implementation. This will be reduced slightly by the server-side refactoring in progress. In the 2.1.1 codebase, all incoming objects will trigger two finds. The first is to load the domain object to process the request. The second will be to determine if the object has been deleted. A hook will be available to inject more efficient logic to determine if an object has become irretrievable. Is there an ETA for GWT 2.1.1? -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: [gwt-contrib] Re: Not using dvsDataMap on child entities
Any updates on this issue? It seems very much like a bug as opposed to a purposeful design choice. All the editors work with object graphs and it makes sense to persist changes by sending object graph.

Re: [gwt-contrib] Re: Not using dvsDataMap on child entities
More notes on this: Say I have the following relationship, a User has a list of OfficeHours. Using the editor framework, I can create OfficeHours proxies, add them to User and persist() and get the whole graph, including new OfficeHours, on the server. If I add a new OfficeHours proxy and update an existing one and persist(), I get the whole graph (with the update) on the server. However, if all I do is update an OfficeHours proxy, then the JsonRequestProcessor sends me the copy it got from OfficeHours::findOfficeHours() instead of the updated version.
