I’m in the process of implementing Roku Voice support. For the most part, I have it working except for one issue. The ObserveField events do not fire on my Video screen. It’s somehow related to the way I start the video content.
During normal processing, the video content is started from a Details screen, and the events fire as expected. My (new) Voice code starts the Video screen from within main.brs in the message loop. I detect the “transport” event and show my Video screen. The video starts and responds to voice commands.
If I use the remote to stop the video and return to the top scene (Grid screen), the events do not fire because when the Video screen was started, I get:
BRIGHTSCRIPT: ERROR: roSGNode.ObserveField: no active host node
on some field values I track to know when the Video state has changed.
Can anyone shed some light on how to resolve this?
