The issues WFLY-3425 and WFLY-3698 have been marked as resolved but I don't see that this behavior has been fixed.

Please see this problem: http://stackoverflow.com/questions/28149056/jbas016069-error-injecting-persistence-unit-into-cdi-managed-bean-when-deplo?noredirect=1#comment44670857_28149056

The problem is that if you deploy a module (EJB-JAR, EAR, ...) with a JPA persistence setup and maybe DAOs in it and you include a beans.xml with bean-discovery-mode set to 'all' or 'annotated' then at a first glance everything works fine, f.i. if you work with the DAOs inside this module. But as soon as you deploy another module where you want to inject these DAOs, you need to set a dependency to the first module in order to be able to use @Inject. But at deployment time CDI tries to inject the persistence unit into the DAO and fails with the following error:

java.lang.IllegalArgumentException: JBAS016069: Error injecting persistence unit into CDI managed bean. Can't find a persistence unit named indra in deployment test-ui.war
	at org.jboss.as.weld.services.bootstrap.WeldJpaInjectionServices.getScopedPUName(WeldJpaInjectionServices.java:110)
	at org.jboss.as.weld.services.bootstrap.WeldJpaInjectionServices.registerPersistenceContextInjectionPoint(WeldJpaInjectionServices.java:73)
...

Is this a bug or intended behavior? I think the injection of the DAOs into other modules is a valid usecase and thus disabling CDI for the DAO-module is not an option.
