-------------------------------

Hi Shazron,

Looks like this one didn't make it for 3.1.0 - are there plans to look into it for 3.2.0?

> Minimal example reproducing the problem is attached and set up as follows:
>  # Custom container view controller split into two halves each containing a _CDVViewController_
>  # Top half loads and after a delay (3000ms) fires a _NSNotification_
>  # In response to the _NSNotification_ the top half loads a green page and the bottom half loads a red page
> Both red pages and green pages have an event listener for *deviceready*:
> {code}
> function onDeviceReady() {
>     alert('deviceready from XXXXX'); // colour here
>     cordova.exec(null, null, 'Echo', 'echo', ['hello']);
> };
> {code}
> {panel:title=Observed Behaviour|borderStyle=dashed|borderColor=#ccc|titleBGColor=#F7D6C1|bgColor=#FFFFCE}
>  - _deviceready_ is fired only for the red page (bottom)
>  - The _cordova.exec_ succeeds for the red page (bottom)
>  - _deviceready_ is not fired for the green page (top)
> {panel}
> {panel:title=Expected Behaviour|borderStyle=dashed|borderColor=#ccc|titleBGColor=#F7D6C1|bgColor=#FFFFCE}
> _deviceready_ should be fired for both the green and red page simultaneously and the _cordova.exec_ events should go through immediately.
> {panel}
> {panel:title=Extra Details|borderStyle=dashed|borderColor=#ccc|titleBGColor=#F7D6C1|bgColor=#FFFFCE}
> This bug reproduces the first time the app is launched (reset the simulator to reproduce). On subsequent launches the app behaves as expected.
> The _deviceready_ can be triggered by certain events for the top page:
>  - Pulling down the notification bar
>  - Backgrounding
> If _deviceready_ is triggered by pulling down the notification bar, the _cordova.exec_ is still not fired for the green page. The _cordova.exec_ message is queued up and finally does go through when the app is backgrounded.
> {panel}
> This bug is remarkably similar to the following:
> https://issues.apache.org/jira/browse/CB-2094
> Perhaps it is an edge case which was overlooked? This bug reproduces on 2.3.0 and 2.7.0 - I have not tried other versions yet.
