Launch "Invisible HTML5 Panel" on host app launch?

Hi There,

I would like to force launch an invisible CEP panel when After Effects launches, and I think this is accomplished via the <StartOn> XML element in the manifest which is a child of the <Lifecycle> element.   I thought that maybe at least one of the following Photoshop events might also be dispatched by AE, but for whatever reason, my panel does not initialize when I begin the debugging process. 

• "com.adobe.csxs.events.AppOnline"
• "applicationActivate"

The invisible CEP panel runs initialization code that attaches a helper class to the globally accessible $ object that other ExtendScripts can access.  I test by launching AE, then inspecting the $ object.  If I make the CEP panel visible and spawn from AE's "Window > Extensions" menu, I do see that the initialization code runs.

Does AE dispatch any events related to its application lifecycle?  I have attached the manifest below for clarity sake.  I've tried both "com.adobe.csxs.events.AppOnline" and "applicationActivate" with AE and it appears that the invisible CEP panel does not initialize.  Any further information regarding AE specifically is appreciated.

The documentation on invisible panels leaves AE off the list in the table.  Does that mean invisible panels do not function in AE?

Thanks,

Arie
