Subject Re: SCR: Issues with static reference mixed with multiple dynamic ref
Date Mon, 28 Nov 2016 11:26:56 GMT
Hi Neil,

Thanks for the quick reply.

okay I see, I misinterpreted the specs then.

In my specific case, I need to make sure the static reference is there
*before* the dynamic ones. What is the best patterns to ensure that ? Do I
need to write synchonization code inside my component for that, or do you
know a cleaner way with declarative services ?

Thanks!

Nicolas
