Roku Smart TV - LabelList not showing

Archived
1

I am submitting a Roku channel, and it is continually rejected because the “Play” button doesn’t show up on the Springboard.
I used one of the templates for the base code. It puts the “Play” button on screen using a LabelList. It works perfectly fine on the device I test on, which is a Roku stick. They seem to be testing these on a Roku Smart TV though, and something about that device is preventing the LabelList from showing.

Below is the code the adds the content to the LabelList.

Sub OnContentChange()
    content = m.top.content
    m.description.content = content
    m.description.Description.width = "770"
    m.poster.uri = content.hdBackgroundImageUrl
    m.background.uri = content.hdBackgroundImageUrl

    m.buttonArray = []

    moviePlaysSection = CreateObject("roRegistrySection", "MoviePlays")
    if moviePlaysSection.Exists(content.guid)
        m.currentPosition = StrToI(moviePlaysSection.Read(content.guid))
    end if

    if content.url <> ""
        m.buttonArray.push({ title : "Play" })
    end if

    if content.trailerUrl <> invalid
        m.buttonArray.push({ title : "Play Trailer" })    
    end if

    m.buttons.content = ContentList2SimpleNode(m.buttonArray)
End Sub

Function ContentList2SimpleNode(contentList as Object, nodeType = "ContentNode" as String) as Object
    result = createObject("roSGNode",nodeType)
    if result <> invalid
        for each itemAA in contentList
            item = createObject("roSGNode", nodeType)
            item.setFields(itemAA)
            result.appendChild(item)
        end for
    end if
    return result
End Function

Is there something weird about the Roku Smart TV that prevents LabelLists from displaying or am I doing something wrong?

It turns out that on older Roku firmware, you can’t create instances of the roRegistrySection in the main thread. Therefore, you have to wrap interactions with it in a Task. I was using a newer firmware version where accessing it in the main thread isn’t an issue. However, the Roku tester was using the previous version, where this was an issue. I hope this helps someone.
