Populating GridScreen with setContentList from XML

I am using a combination of GridScreen and VideoScreen examples from the SDK. My goal is to make a GridScreen populated from XML which is hosted on my server. I am populating the List Names properly, but cannot figure out for the life of me how to populate the list of content in the rowIndex (setContentList function). Here are all the relevant code snippets I am using:

XML - EDIT: READ BELOW POST TO SEE SOLUTION!!!
(for now just using a very slightly modified sample feed XML from the SDK. Once I have this working I will make custom XML with my own content)

Relevant part of my appGridScreen.brs. Once again, I am getting the List Names, but cannot populate the contents.

Function showGridScreen(screen As Object, gridstyle as string) As string

print "enter showGridScreen"

conn = InitCategoryFeedConnection()

m.Categories = conn.LoadCategoryFeed(conn)
m.CategoryNames = conn.GetCategoryNames(m.Categories)

categoryList = conn.GetCategoryNames(m.Categories)

screen.setupLists(categoryList.count())
screen.SetListNames(categoryList)

initCategoryList()

for i = 0 to categoryList.count()-1
screen.SetContentList(i, getShowsForCategoryItem(m.CategoryNames))
end for
screen.Show()


The problem part is the last for loop. I am just not sure what the heck to pass to the getShowsForCategoryItem function, which currently looks like this:

Function getShowsForCategoryItem(category As Object) As Object

print "getting shows for category "; category

conn = InitShowFeedConnection(category.kids)
showList = conn.LoadShowFeed(conn)

return showList

End Function


So if you have a suggestion of how to populate the ListNames with the appropriate content, please let me know!
Thanks.

Re: Populating GridScreen with setContentList from XML

So this took me almost a day to figure out but I finally got it. Here's the solution just in case someone sees this thread in the future!

The issue was that I needed to remove categoryLeafs from the example videoplayer. There is quite a bit of code you have to change to do this properly, so I followed the step-by-step tutorial here:

viewtopic.php?f=34&t=57936

The for loop in showGridScreen ends up looking like this:

for i = 0 to categoryList.count()-1
m.curCategory = i
screen.SetContentList(i, getShowsForCategoryItem(m.Categories.kids[i]))
end for
screen.Show()

...


and here is getShowsForCategoryItem:

Function getShowsForCategoryItem(category As Object) As Object

print "getting shows for category "; category

conn = InitShowFeedConnection(category)
showList = conn.LoadShowFeed(conn)

return showList

End Function
