I'm working with an existing code base, so I assumed all the classes I had were part of the original SparkTree code. Apologies for the confusion. My tree implementation will probably max out at around 30 items, so it's not a big issue for now. Thanks for taking the time to answer all my queries though :) Kim That explains a lot..

The closes event I can imagine is <code>CHANGE</code>, but it does not arrive twice if you scroll selected item out and in. I strongly discourage the use of <code>useVirtualLayout=false</code> because it will cause performance problems when list data size increase. If you can reproduce this bug on an empty project I will be glad to help you. Cheers! Spark List does not have ITEM_SELECTED event.

If a selected item is scrolled out of view, when it is scrolled back into view it re-dispatches the <code>ITEM_SELECTED</code> event. I've fixed this by using <code>useVirtualLayout=false</code> when adding the component to my project, but maybe there's a better way.

Then place breakpoint in <code>Tree.preinitializeHandler()</code>, you'll see how styles are handled in your module's tree.

I used code to open the branches and then i could see all the leafs.. so it's just the + sign not showing up. I did not have the mx tree component in my project, but the problem is that i'm using modules that are loaded on runtime. The component works perfectly when i use it in my main application, but not in the modules. But i cannot reproduce it in an empty project so far. I'm using altered modules and load them via a class that handles everything (loading/displaying/removing/..) for my modules. I will keep trying to reproduce it! Hello,

I recently updated the library with some style improvements, you may just not see the open/close icon. 1. Do you have MX Tree in the project? In this case Spark Tree will use it's icons 2. Can you reproduce it on an empty project? Thanks. Hi Ramses! I recently updated the library with some style improvements, you may just not see the open/close icon.

The only way you can do this is get the library source and modify it. P.S: You may have problems with memory leaks in this case if you will store links to open branches. You will need some hash-function or node ID. Hi Kim! The only way you can do this is get the library source and modify it.

I only see the top levels and no branches in the tree. I thought i was as simple as giving the objects in the ArrayCollection a property "children" but nothing is showing except for the top levels. The objects i use are generated objects from Flash Builder and are retrieved from our backend. This is the same for the objects in the children property. This is a ArrayCollection of generated objects. Any idea what the problem might be? Thanks in advance! Hello Maxim,

Is it possible to prevent this? Many thanks - Kim Hey there – at the moment, the tree automatically closes all child branches when closing a branch. Is it possible to prevent this?
