Migrating patch panel with SWF from CS4 to CC2014

Hi,

I'm trying to migrate some legacy code for a patch panel written in Flex / Flash for InDesign to work in CC2014.

Currently, it is falling over as there is a var "InDesign" that was previously set but is no longer set.

EG: In order to get a reference to the app object, the code was using;

app = InDesign.app; //this variable is already present if this is run by indesign.

But "InDesign" has not been set.

So...

Two questions;

1. Has the object name changed, if so, what to?

2. Is there any additional step I need to do to get InDesign / Flash integration working for Patch Panel?

And a further one...

3. Assuming that this is still possible and still supported, how can I debug using Flash Builder with InDesign?

Thanks,
G
