I have a large XML data set to display in an a Flex ADG. My strategy so far has been to first load just the top most hierarchy of data. As the data is expanded, I have a custom item renderer that creates an HTTPService to fetch more data. I was so happy to see that this worked... until I reached 20 fetches. Things just stop working. Am I using the right strategy? At this point I've loaded less than 4 mb of data so I don't think memory is the problem. (sdk 3.2 Mac 10.5 intel/WinXP Pro both have same behavior).
