Thanks.

Can you please explain your code or provide me a project file ofcorse alongwith the whole working code?

I have been trying the same trick for FileSystemTree in AIR but it does not work.

When I click on the row, I see the triangle looking down. I click again, it goes back to its initial position. I trace if the branch is open and get false/true so no problem there. However, the tree structure does not update itself. Moreover, if I happen to click on the triangle first, then everything works smoothly. There must be something about disclosure events, right?

Nice example. Can you explain how to display only the nodes we want ?

For example, in your XML, you have “folder” nodes and “item” nodes, and I would like to only show “folder” nodes.

Is it possible ?

Thanks,

Sam
