Hi Christan, thanks, I didn't have these dependencies. Added them, but am still getting the same error. I just upgraded the project from 2.4 to 3.0, primarily so that I can use the BatchCaller. Am sure than I'm missing another dependency. What else could it be?

Errai inherits in the GWT module:

<inherits name="org.jboss.errai.bus.ErraiBus"/>
<inherits name="org.jboss.errai.ioc.Container"/>
<inherits name="org.jboss.errai.ioc.support.bus.BusSupport" />
<inherits name="org.jboss.errai.marshalling.ErraiMarshalling" />

Errai components in the pom:

- errai-bus

- errai-ioc

- errai-ioc-bus-support

- errai-uibinder

- errai-tools

(I'm not using CDI, mainly because it was/is conflicting with GWTP. Maybe the new GWTP 1.0.1 will help, but have to sort out some upgrade problems there first.)

Many thanks!

Cheers,

V.

Hello Erik Jan, will try. The actual project is quite large, will have to reproduce the configuration and carve out the relevant bits. Will take some time.

I still believe that I'm most probably missing a dependency or a configuration in the 2.4 to 3.0 migration.

Interestingly, the problem I run into with the GWTP upgrade from 0.7 to 1.0.1 is very similar. There the generated code in the Bootstrapper calls a default constructor that no longer exists. It's like I'm missing a provider there somehow.

Cheers,

V.

As a workaround I added the provider binding in my gin module like this:

bind(BatchCaller.class).toProvider(BatchCallerProvider.class);

Now I can inject the BatchCaller. Is this the intended usage?

Cool, thanks. I'm not using CDI currently.
