Pete, Mark,<br><br>So I get there is no single injection point, however it should be the case that every injection point is declared the same way, no? E.g. they're the "same" in the sense that the line of code is the same, but different in that they exist in different areas.<br>

For a request scoped bean there is not a single injection point, like there is for dependent beans. Say I have a request scoped bean, Bean A.<br>
<br>
I have two other beans, of any scope, Bean B and Bean C.<br>
<br>
If both beans B and C inject A in the same request, then the injection point for A is both Bean B and Bean C.<br>
<br>
Furthermore, client proxies mean that bean A is instantiated lazily, to solve the circular injection problem, and so has no knowledge of it's injection point when actually created.<br>

However, CDI disallows this since the producer methods used to create them would not have access to the injection point. If a second injection point is found, CDI should return the same instance.<br>
