I am trying to understand why @Factory is much less well represented in Seam examples than @Out (7 vs. 21 in CR2). On the first glance, factories seem to play the same role as outjections, just lazy (or call it demand-drivden, pull-like, data flow, etc.). This mode of operation looks safer than outjections (supply-driven, push-like, etc.), as it automatically ensures synchronization of provider of a value and a consumer of this value; while using outjections, one must be carefull to synchronize components "manually" (probably using Seam events).
On the second glance, factories lack one feature supported by outjections - namely scoping. Using @Out it is possible to have multiple bindings for the same name in different scopes, while I don't see how this is possible for factories (in the current implementation). So one question is - why are factories not used more often (and recommended to be used more often), and the another - why scoping is supported for eager value producers (@Out) but not for lazy ones (@Factory)?
