Root Cause: As mentioned this seems to be a multithreading issue with declarative services. Exact cause unknown, it seems like the DS version we are currently using (1.4.100.v20130515) cannot handle nested components threadsafely if they are all set to immediate instantiation. This causes DS to skip calling the bind method in one component.
Setting component instantiation to "on-demand" (immediate=false) seems to bypass this issue.
Update the Automation Engine to version 12.1.1 or later.
Fix Status: Released
Component(s): Automation Engine - REST API
Automation Engine 12.1.1 - Available
