[Flow] Constructor injection and IDE

[Mathis Hoffmann]

Hello Christian,

thanks for your quick reply!

But what you suggest is, as I understand everything right, not 
constructor injection but only dependency injection in general. This 
works in most cases but not if you have a constructor that uses the 
injected properties. The problem is that this "standard dependency 
injection" happens after my constructor is called. So if I for example 
need a repository in my own constructor and call $respository->findAll() 
I get an error that tells me that I must not call findAll() on a non 
object. That's why I specifically need constructor injection in this case.

I'm not really shure weather what I just wrote ist absolutely right. But 
looking into the generated proxy class I found that the proxy first 
calls my original constructor and only afterwards injects the 
properties: http://pastebin.com/GG5KAy4v

Cheers
Mathis
