[jboss-user] [JBoss Seam] - Re: Question regarding performance and multiple JavaBean bij

Each time that you call a method on your Seam component, Seam will biject as required. When the method is complete Seam disinjects the any injections. So, each time you call #{testBean.testValue}, you get an injection. As for why each #{testBean.testValue} causes two injections, that's probably down to JSF/Facelets evaluating the binding twice. By the time you access #{testValue} on your page it has been outjected by testBean and so exists as a contextual variable and hence doesn't access the bean at all. anonymous wrote : | Now I wonder: | * Is this behavior a bug?

No. anonymous wrote : Also: | * To get the @Out outjection to work, I must first access the bean (with #{testBean.testValue} for instance). Is there another way to "wake up" the bean so that @Out works? Look at using @Factory or @Create (there are examples of both in examples directory. In general we (Gavin) have done a very good job of making Seam fast - there are discussions about this on the forum, take a look through. The normal candidate for slowness is in your use of the ORM.
