>          Components: iOS
>         Environment: Reproducible on iPad/iPhone 5.0 and 6.0 simulator
>            Reporter: Mike Kwan
>            Assignee: Andrew Grieve

> Steps taken to reproduce:
> 1. Create custom container view controller
> 2. In viewDidLoad add two CDVViewControllers as childViewControllers and hook up view
hierarchy appropriately
> 3. deviceready will fire for startPage on the first CDVViewController but not for the
second
> Workaround:
> Add the second CDVViewController after some delay (e.g. 1 second)

> More info:
> After some investigation, the problem seems to be a manifestation of a race condition
where the address of the CDVViewController passes in the user-agent is clobbered. This means
sometimes one CDVViewController will get deviceready and at other times the other one will
(but never both).
