Yeah, well... Method injection didn't work either, the method just
never got called (as expected...)
I finally was able to make it work using the technique you proposed by
initializing the generated classes after the injector is created.
Just to give a bit more details to anybody else interested in this...
Here is how you define a configuration property in your
project.gwt.xml:
<define-configuration-property name="gin.injector" is-multi-
valued="false" />
<set-configuration-property name="gin.injector"
value="com.project.client.gin.MyGinjector" />
Here is how you access this property in your generator:
String ginjectorClassName =
ctx.getPropertyOracle().getConfigurationProperty("gin.injector").getValues().get(0);
Now if you want an injector in the source code you generate you do:
writer.println( ginjectorClassName + " injector = GWT.create(" +
ginjectorClassName + ".class);" );
Thanks again Gal. This is a neat trick!
