Quickly scrolling through categories in roPosterScreen?

I have an roPosterScreen with 5 filter categories: 'A' 'B' 'C' 'D' and 'E'.

If I start at category 'A', and then (as fast as I can) scroll through categories 'B', 'C', and 'D' until I finally rest on category 'E', I see the following behavior:

retrieving...display contents for category 'A'
retrieving...quickly display contents for category 'B'
retrieving...quickly display contents for category 'C'
retrieving...quickly display contents for category 'D'
retrieving...display contents for category 'E'

In most other channels with a similar setup, I see the following behavior:


retrieving...display contents for category 'A'
retrieving...display contents for category 'E'

Does this problem sound familiar to anybody? I feel like there's a rule of thumb that I must not be following.

Thanks!

My first guess would be that it is simple lag with the channel site.? I'd prefer the second option too.

I know in the Justin.TV channel TheEndless has about a one second delay before he retrieves the contents for a category.

It sounds like you're populating your content list in the isListFocused event. You may want to consider setting a flag in that event instead and populating the flagged list a second later.

Yup, your assumption was correct and your suggestion works great. Thanks again!
