I think i found the problem. When i set the vertFocusAnimationStyle = "fixedFoucse" sections does not show up. But when i set the vertFocusAnimationStyle = "fixedFocusWrap" Sections show up.
Can any one at Roku confirm if this is platform issue or something i am not doing right or Sections are only supported with "fixedFocusWrap"?
I hacked (as with most things on Roku) around the issue of item retrieval by also creating and populating a flat version of my content and using that for accessing the data. For example:
section = createObject("roSGNode", "ContentNode")
section.contentType = "SECTION"
for each item in items
m.markupList.content = section end sub ... sub onItemFocused() selectedNode = m.flatContent.getChild(m.markupList.itemFocused) ... end sub
