It doesn't sound like a MOVE should be fired, but its hard to tell without a sample application. Any chance you can provide a small sample application that demonstrates this so we can investigate further?
It is not moving "into view" it is simply changing its position in the
current view. If you have a filter applied and the set of items that pass
the filter can be affected by changing the expanded state, you can get a
MOVE, because the item in question might have a different index.
Thanks Flex harUI! Sorting was the caused. To solve the issue, I simply add another sortfield (in my case, a Date object).
Shongrunden, thanks for posting a link to a bug in one of your previous posts on this forum. I came across bug SDK-25412 in development, searched this forum for solutions and came to your post. I used the first workaround method in the description for this bug, "After setting the data provider, reset the itemRendererFunction to the same function."
Thanks again guys.
