Multi module project: code server launched for the "wrong" project

I have a multi module project which contains:

1) server module [packaging WAR]
2) shared module [packaging JAR]]
3) client app module [packaging gwt-app]
4) client library module [packaging gwt-lib]

After Tomcat is started successfully, Eclipse starts the CodeServer run configuration of the client library module (which has not a GWT EntryPoint). Instead, it should start the CodeServer run configuration of the client app module.
If I starts manually the CodeServer for the clien app module then it works fine.
It seems that the plugin takes the wrong GWT module.
Thanks in advance and Merry Christmas!
