Injection issue using Resource Delegates client side (gwtp 1.4)

[Casey Jordan]

So I have Resource Delegates working pretty well server side, but when I try and use them in my client side code I get gin injection errors.

The relevant error is here:

com.jorsek.apps.mapeditor.client.MapEditorWorkspacePresenter$Factory [com.jorsek.apps.mapeditor.client.gin.MapEditorClientModule.configure(MapEditorClientModule.java:46)]

[INFO]  -> com.gwtplatform.dispatch.rest.delegates.client.ResourceDelegate<com.jorsek.api.shared.rest.FilesResource> [member injection of com.jorsek.apps.mapeditor.client.MapEditorWorkspacePresenter#filesDelegate]

I have added the module to my gwt.xml file as per the documentation, and I am injecting into my presenter:

@Inject
ResourceDelegate<FilesResource> filesDelegate;

The only thing I can think of is that looking at the com.gwtplatform.dispatch.rest.delegates.rebindDelegateModule I don't see ResourceDelegate specifically bound anywhere, but perhaps this is something that happens in the code generation that I am not seeing. 

Any pointers would be much appreciated. 

Thanks!

The stack trace you pasted only says that gin injected the ResourceDelegate in the filesDelegate field. Can you provide more of your stacktrace?

Thanks

Thanks for the response Chris. Here is everything that is output. This error goes away when I comment out the injection for the resource delegate.

Thanks for the stack trace. I have a couple more questions though:

- Do you have any issues with Rest-Dispatch alone (without the resource delegates)?

- Also double check that the ResourceDelegate inherit is after the DispatchRest inherit in your .gwt.xml.

- If it is the case, run the gwt compiler with the following argument: "-gen target/gwt-generated". After the compilation is done, verify that "target/gwt-generated/com/gwtplatform/dispatch/rest/client/RestGinModule.java" exists. Does it contain a binding similar to this?

bind(new TypeLiteral<ResourceDelegate<com.jorsek.api.shared.rest.FilesResource>>() {})
        .to(FilesResourceDelegate.class)
        .in(Singleton.class);

[Casey Jordan]

Hey Chris,

Thanks. I just dug into this more and I found out that that it was becuase one of the classes that my rest resource was using was not serializable and that was causing the code generation to fail.

When this happens, do you know if there is a way to actually get a reasonable error describing this. It seems to me that the system should say something more like:

"XXX class failed to meet the serialization requirements"

That would have saved me about 3 days :)

[Christopher Viel]

Not that I know of. You can raise the logging levels to debug/trace/spam, but then you get so many logs that finding anything relevant is a pain. This is an issue we too would like to resolve. My feeling is that it would need some work in GWT and/or Gin.
