I'm having the same problem so if you've found a way to resolve this since your post, would you please let me know?
Thanks in advance
Same problem here:
[testng] Caused by: javax.ejb.EJBException: org.jboss.seam.RequiredException: @In attribute requires non-null value: myTest.renderer
In another thread on that forum, someone suggested to add the jboss-seam-ui or facelet jars. When I try that, it's worse, it doesn't even start my app:
[testng] Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/seam/mock/SeamTest
[testng] at java.lang.ClassLoader.defineClass1(Native Method)
[testng] at java.lang.ClassLoader.defineClass(ClassLoader.java:675)
[testng] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124)
I added both dependencies and it works just fine now... I even removed the jboss-seam-ui dependency and it still works... I don't know why you got this error when adding those jars... it may be a classpath error or something like that.
Thanks for helping me out... I'm kinda sorry it doesn't work for you though :/
