I meant if I were using the current injections (via setters, not getters), and didn't inject anything for B, but just called doStuff(), I would get an NPE.
Just rewrite the code I suggested to return null instead of throwing UOE, and the failure will be the same for both patterns - NPE in face of missing injection. Note that I didn't talk about subclassing my component class, Seam could just intercept the call to getB, lookup the value of B and return the value - JIT injection, not sooner when needed. This JIT nature of injection via getters is their added value compared to injection via setters or fields. The same effect could be achieved by using Contexts.lookupInStatefulContexts and a type cast inside getB, but then why using annotations and interceptors at all? :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3947304#3947304 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3947304 ------------------------------------------------------- All the advantages of Linux Managed Hosting--Without the Cost and Risk!
