[jboss-user] [JBoss Seam] - @Factory and @Out: why required=false?

Ok, I'm not understanding something here. I have a SFSB that with a snippet that looks like this: | @Out private Foo foo; | | @Factory("foo") private void makeFoo() { .... } | and that causes a "foo did not exist but was required" exception when a page is first accessed. This is within a conversation, and this is the first page to be accessed in that conversation. If I put @Out(required=false) then it works as expected. I don't get this. Foo is required, but shouldn't the factory always create it when it is needed? How can an @Out fail if there is a factory for that component? I'm still not totally understanding the interplay between @Out and @Factory, and I'm also sometimes getting concurrent access exceptions if I try to do things in both @Begin and @Factory. I know these things all have logic behind them but it hasn't sunk in to me yet. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3998862#...
