Requestfactory Validation on Multi-Project Setup - gwt

Question

I tried changing to the release version of gwt2.4 and run into a problem. I use multiple projects in my setup. I have a project with serverside code, one project with shared code, that can be used in different gwt projects and a gwt project binding everything together. I build everything with maven. i followed the instructions for annotationprocessing found here:
http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation
when I compile my shared project, where the proxies and services are, the folder "generated-sources\apt\" with the DeobfuscatorBuilder.java is created. I have the sources of this project as dependency of my mainproject and try to run the validator as well, but the DeobfuscatorBuilder.java is not created here. Everything compiles but when I invoke a call to the requestfactory I get the error:
com.google.web.bindery.requestfactory.server.UnexpectedException: No RequestContext for operation ZwI9iqZS626uTt_TFwRtUwPYSOE=
I guess there is an mistake in my setup, but I could't find where ..
Does anybody know how to solve this problem?

UPDATE:
I added this to my pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>unpack</id>
<phase>initialize</phase>
<goals>
<goal>unpack</goal>
<!-- <goal>build-classpath</goal> -->
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>com.myproject.core</groupId>
<artifactId>shared</artifactId>
<version>${shared.version}</version>
<classifier>sources</classifier>
<overWrite>true</overWrite>
<outputDirectory>${project.build.directory}/com.myproject.shared</outputDirectory>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
This unpacks the sources of my dependencies and puts them into my target folder.
Then I added:
<configuration>
<sourceDirectory>target/com.fileee.shared</sourceDirectory>
</configuration>
to my processor-plugin.
This way it is not necessary to have all the projects in the workspace and it should work with a continous integration system. Wouldn't have figured that out without Andys reply though :)

Answer 1

I had the same issue and spent hours scouring the web for an answer without any luck. If I add the processor plugin to the shared project, it generates the DeobfuscatorBuilder class, but I get the same No RequestContext exception as you. If I just have the processsor plugin on the GWT war project, the builder isn't generated at all.
With a fair amount of trial and error I found adding the source directory from the shared project into the processor plugin configuration on the war project worked...

It's a bit dirty, but it does the trick. If there's an official method that doesn't require cross project hackery I'd be more than welcome to switch, but I haven't seen anything suggested yet.
