Re: Lookup bean using beanManager returning null

[Thomas Andraschko]

Have a look at the bean manager java doc ->

*getBeans
<http://docs.oracle.com/javaee/6/api/javax/enterprise/inject/spi/BeanManager.html#getBeans%28java.lang.reflect.Type,%20java.lang.annotation.Annotation...%29>*(java.lang.reflect.Type
beanType,
java.lang.annotation.Annotation... qualifiers)

RequestScoped isn't a CDI qualifier! ;)
