Is there an official contact/email I can use?

I am using one of Roku sample demos: https://github.com/rokudev/hero-grid-channel

This is an important project for the company I am building, however, I need to be able to add video element dynamically to the Poster element within the Grid on the fly that requires me to target the Poster.

However, in my other forum post, assigning an ID to the poster element did nothing. Using m.top.findNode does not seem to find it.

Is this a bug within the SDK? Is there a support email.

Thanks!

The best way to get help would be to post the complete code you're using for both your scene's .xml and .brs files.

If there is clearly a bug, you can try reporting at the samlpe https://github.com/rokudev/hero-grid-channel/issues

In theory you could email developer @roku.com but in practice, this year 9 out of 10 emails remain unanswered (from couple of feelers, RokuCo management are blissfully unaware of the fact). Even if they were answering all email though (which they could and should!), do realize that specific code customization help is provided only to a few, key "partners" - in Co's boutique parlance.

From previous thread, it does not sound you have run into a bug proper - so like @belltown suggests, best to show code in the forum, so it can be collectively dissected and triaged. That is known to work. Plus the rubber ducking effect which i can vouch for Smiley Happy

The question might not be why my method doesn't work. But how can it be done.
How would you dynamically add "video" element into rowlist item? Is there an alternative to RowList? Or like how would you change an image onFocus event... has anyone done that?
