Re: RequestFactory, ValueProxy support for Email, Link, User
For posterity:
After setting up the Annotation Processor, I realized there were many other
issues. But User object isn't one of them. It works fine. Link, on the
other hand, does not - the reason for this is that Link object doesn't have
a default constructor. So we get errors if we try to make a LinkProxy for
it. I decided to store my link just as a String, instead of Link.

Hi GWT team,
I've just started migrating from GWT-RPC to RequestFactory, and noticed
that even when using ValueProxy to wrap the datastore objects, they aren't
supported. For e.g, I created a UserProxy and a LinkProxy:
import com.google.appengine.api.users.User;
import com.google.web.bindery.requestfactory.shared.ProxyFor;
import com.google.web.bindery.requestfactory.shared.ValueProxy;
@ProxyFor(User.class)
public interface UserProxy extends ValueProxy {
String getUserId();
String getEmail();
String getNickName();
String getAuthDomain();
String getFederatedIdentity();
}
package com.kuryaat.lms.common.newdto;
import com.google.appengine.api.datastore.Link;
import com.google.web.bindery.requestfactory.shared.ProxyFor;
import com.google.web.bindery.requestfactory.shared.ValueProxy;
@ProxyFor(Link.class)
public interface LinkProxy extends ValueProxy {
String getValue();
}
And I'm using them like this:
import com.google.web.bindery.requestfactory.shared.EntityProxy;
import com.google.web.bindery.requestfactory.shared.ProxyFor;
import com.kuryaat.lms.common.dto.DocRefType;
import com.kuryaat.lms.server.jdo.DocRef;
import com.kuryaat.lms.server.rf.DocRefLocator;
@ProxyFor(value = DocRef.class, locator = DocRefLocator.class)
public interface DocRefProxy extends EntityProxy {
String getName();
LinkProxy getLink();
DocRefType getDocType();
int getStackIndex();
String getSourceService();
}
But I get the following error when I try to run the code:
[ERROR] [myapp] - Line 7: User cannot be resolved to a type
What is the right way to handle these?
Thanks,
Avanish

RFED flushed context reaches server without nested entity changes
Hi GWT Gurus, I've been trying to get GWT RequestFactoryEditorDriver working for my entities with relationship - A contains a ListB. My editors display my data just fine now, and changes to a.name persist perfectly as well. Also, when I change the value of a b.name and do a driver.flush(), on inspecting the returned context in Eclipse, my change to b.name is present. However, when I context.fire() my saveAndReturn method, the server-side object doesn't contain my b.name change. How could this be happening? (I also posted my question on StackOverflow with detailed code snippets: http://stackoverflow.com/questions/14041275/request-factory-gwt-editor-change-isnt-persisting-related-jdo-entities ) Please do help! (I promise to write up a summary of my issues and solutions on my blog and link it back here once I've figured this out and can finally save my data!)

Re: Gwt 2.2, guice and gin...
Hi Goktug!
(+google-gin for posterity)
Thanks for the reply! I dug deeper into this today, and nailed it. It was
indeed a Classpath issue. In specific, the ordering. Perhaps one of the
GWT/RequestFactory, or other libraries were overriding the javax.inject
imports that are provided by GIN.
Here's the order that finally worked:
aopalliance.jar
gin-2.0.jar
guice-3.0.jar
guice-assistedinject-3.0.jar
javax.inject.jar
I made the change in Eclipse: Project Build Path Configure Build Path
Order and Export. Select all of the above, and choose Top, and then tick
all of the JARS. Any other way, I would continue to get the error. (The
only thing I didn't try is juggling around the order of these specific JARS)
One more issue I ran into, and Thomas(tbroyer) has already answered on
StackOverflow:
https://groups.google.com/forum/?fromgroups=#!topic/google-web-toolkit/0v6gpPEzBAU
I ran into this NPE, which happens because I was injecting the
RequestFactory, and not running initialize on it. Solved by writing a
Provider in my GinModule:
@Provides
@Singleton
MyAppRequestFactory provideMyAppRequestFactory(EventBus eventBus) {
MyAppRequestFactory requestFactory =
GWT.create(MyAppRequestFactory.class);
requestFactory.initialize(eventBus);
return requestFactory;
}
After that, it runs fine. :) Thanks once again!
Cheers,
Avanish

This may be related to depending on multiple versions of Guice.
As this is related to GIN, google-gin group is a better place to get
support on this. There was even a recent question about it if you search
there.
Good luck and don't forget to share with the rest what worked for you for
future reference :)

Re: Gwt 2.2, guice and gin...
Please help me. I've still not been able to resolve this. At least, any pointers as to why this might be happening? I tried to search online, but this thread is the only reference to this issue that I found. I've even tried to build guice from svn head, and added gin- and gin-src- jars to my project. I still get the same error about: No implementation for javax.inject.Providercom.google.gwt.inject.rebind.GinjectorBindings was bound. Also, currently, I'm only using GIN on client side, and haven't done any server-side Guice setup. Could this be the cause for my problem? In other words, will Gin only work if I'm also using guiceServlet configured?

Google Drive SDK for GWT
Hi Folks, (Posting here since google-gwt-apis isn't accepting any new posts) Back in April, the GWT team indicated there would be support for Drive API/SDK coming. Is there any progress on this? The Drive SDK page https://developers.google.com/drive/downloads does mention GWT(alpha) support. However, when I click through to the GWT linkhttp://code.google.com/p/gwt-google-apis/, there is no mention of Drive. Is this coming soon? If not, are there any templates/examples I could follow to create a JSNI or Javascript Overlay wrapper for Drive? Thanks, Avanish -- Life is what you make of it Y. Avanish Raju, Google Inc.
