Sounds like there might be an issue with the renderer. What does your index handling code look like?

(idx 0-35 are numbers, 36 is null, 37-39 are numbers.) The values are equal to the index+1, so index 1=2, and index 35=36. As soon as I hit the null value at idx 36, all values afterward are shown as blank. Then if I scroll back up the list, all the previous values are null too! So as soon as the null value is loaded into the tree renderers, all previous and future data is nullified. I have tried hiding the null data by implementing a custom data descriptor, as well as extending the tree class itself to override the isVisible and isEnabled methods, but nothing is having any effect. How can I hide these null values, or at least protect the data around the null values? -- Alex Harui Flex SDK Team Adobe System, Inc. http://blogs.adobe.com/aharui
