I've modified the SimpleRowList.zip example found here: https://sdkdocs.roku.com/display/sdkdoc/rowlist

My version utilizes the failedBitmapUri and loadingBitmapUri field, but neither seem to work for me. I've tried with the following modifications:

1. Load a high res image into the poster thumbnail, which should result in a visible loading period for the image.
2. Load a non-existent image, which should cause the poster to fail.

Here's modified project: https://www.dropbox.com/s/bbptomq2cx90k ... i.zip?dl=0

Here's the updated SimpleRowList.xml file, with two modifications:

<?xml version="1.0" encoding="utf-8" ?> 
<component name="SimpleRowList" extends="RowList" >

<script type="text/brightscript" >
<![CDATA[

    function init()
        print "in SimpleRowListPanel init()"
	    m.top.itemComponentName = "SimpleRowListItem"

        '' ----- MODIFIED CODE ----- ''
        m.top.failedBitmapUri="pkg:/images/MainMenu_Icon_Side_SD43.png"
        m.top.loadingBitmapUri="pkg:/images/MainMenu_Icon_Side_SD43.png"
        '' ----- @END MODIFIED CODE ----- ''

	    m.top.numRows = 1
	    m.top.itemSize = [196 * 3 + 20 * 2, 213]
	    m.top.rowHeights = [213]
	    m.top.rowItemSize = [ [196, 213] ]
	    m.top.rowItemSpacing = [ [20, 0] ]		
	    m.top.rowFocusAnimationStyle = "floatingfocus"
            m.top.content = GetRowListContent()
	    m.top.visible = true
	    m.top.SetFocus(true)
	    m.top.ObserveField("rowItemFocused", "onRowItemFocused")
    end function

	function GetRowListContent() as object
	    'Populate the RowList content here
	    data = CreateObject("roSGNode", "ContentNode")
	    row = data.CreateChild("ContentNode")
	    for i = 1 to 3
	        item = row.CreateChild("SimpleRowListItemData")

            '' ----- MODIFIED CODE ----- ''

            '' This image should fail, but we don't see failedLoadingBitmapUri
            item.posterUrl = "http://www.fake.com/this_picture_does_not_exist.jpg"

            ' This is high-res image should take time to load, but we don't see loadingBitmap Uri
            'item.posterUrl = "http://www.hd-wallpapersdownload.com/upload/bulk-upload/high-resolution-lion-pictures.jpg"

            '' ----- @END MODIFIED CODE ----- ''

	        item.labelText = "This is item" + stri(i)
	    end for
            return data
	    print "Leaving GetRowListContent"
	end function

    function onRowItemFocused() as void
        row = m.top.rowItemFocused[0]
        col = m.top.rowItemFocused[1]
        print "Row Focused: " + stri(row)
        print "Col Focused: " + stri(col)
    end function
]]>
</script>
</component>

Also, if I add the attributes directly to the xml, I'll get an error.

Just following up on my own post. This is fixed in firmware 7.1.
