I upgraded my eclipse plugin but made the mistake to remove GWT 2.1.1, so now I have to use GWT 2.2. The problem is that the version r137 of gin is not compatible with GWT 2.2. I found in the GWT groups, some link to snapshot of gin but it doesn't work.

[ERROR] [portfolio] - Generator 'com.google.gwt.inject.rebind.GinjectorGenerator' threw an exception while rebinding 'com.portfolio.client.MyGinjector'

I was wondering if I am missing a jar, and what version of gin you ended up using.

I didn't try Gwt 2.2 yet, I'll have a look when I get back home.

Gwt 2.2 isn't compatible with Gwtp 0.5, yet.

I don't know why but they seem to have changed things with Gwt.Create() that mess the creation of our proxy classes.

We will have to investigate. For an older version of GWT:

Good day, Christian

I upgraded my application to GWT 2.2.0, and upgrade gin to trunk revision. My problem is to occure when I start GWT compile.

GWTP version 0.5

I just read something interesting on another library where the only thing they had to do to remove that error is to rebuild the library with Gwt 2.2 as a dependency.

Here's a more complete explanation from @Tomas Boyer:

GWT 2.2 introduces a binary incompatibility in generators (some classes have been replaced with interfaces), hence the error with GIN (though honestly, it should have been another error thatn the one you pasted here)
It is still source compatible with the previous versions though, so recompiling the generators (GIN in this case) is enough.
Technically, you don't have to upgrade GIN to a 1.1-SNAPSHOT version if you don't want to, but you then have to recompile it against the GWT 2.2 SDK.
I'm not aware of any "GIN 1.0 recompiled for GWT 2.2" available for download though, so given that GIN 1.1 is compatible with GIN 1.0 (unless you're doing "hardcore" things with it), you can safely use a GIN 1.1-SNAPSHOT if you don't want to recompile GIN by yourself.

Except that I was wrong: GIN uses GWT internals (including those modified classes), so it's not source compatible with "any version" of GWT.

I have upgraded the libraries to GWT 2.2, GWTP 0.6 SNAPSHOT, gin-1.0-
r170 and guice 3.0 rc2 to resolve to problem described in this
thread.
Most of the problems have gone but still there is little one lest. It
looks like the generated *MyGinjectorImpl.java is missing methods
returning PresenterWidget providers.

in MyGininjector I have

and in MyModule

bindSingletonPresenterWidget(SessionPresenterWidget.class,
SessionPresenterWidget.MyView.class, SessionView.class);
bindPresenterWidget(VerticalMenuPresenterWidget.class,
VerticalMenuPresenterWidget.MyView.class, VerticalMenuView.class);
bindPresenterWidget(HorizontalMenuPresenterWidget.class,
HorizontalMenuPresenterWidget.MyView.class, HorizontalMenuView.class);

Any thoughts on that?

Thanks in advance

Ok, I have solved it.

I have forget to change reference to the new gwtp-all in Java Compiler -> Annotation Processing -> Factory Path. As result of that the path was pointing to the old file which has been removed.

Strangely the compiler didn't complain about any other generated types. Usually when I was changing versions the IDE was first to complain about Action and Result classes generated by @GenDispatch

Well... here we go.

Hello

I having problems with updating to gwt 2.2.

I have downloaded and referenced:
gin-1.0-r170.jar
guice-3.0-rc2.jar
guice-servlet-3.0-rc2.jar
gwtp-all-0.6-20110217.132630-1.jar

also dereferenced the old libraries, for guice, gin and gwpt.

When i try to compile my project i get the following:

You also need:

guice-assistedinject-3.0-rc2.jar

javax.inject.jar

aopalliance.jar

See http://code.google.com/p/gwt-platform/wiki/PortingV1#Dependencies for the whole list.
