How is the new root node being applied to the Tree? Are you reassigning the dataProvider on the tree or adding the root into the existing “people” ArrayCollection?

thanks for the example, very useful, I’m trying though to get the root node to disappear with no luck , i tried to change the following

private function refreshData():void{

people[0].children = new ArrayCollection(people[0].children.source);

var root:Person = new Persion();
root.children = new ArrayCollection();
root.children.addItem(people[0]);

refreshRecursiveChildren(root);

personsTree.invalidateList();

}

I can see that Grandma Susan is passed now to filterData and return ‘false’ still it shows in the tree !

Prudvi,

I need more information to help. Is this an AIR project? Where is your data coming from and in what format? If you could post it here that would help.

Pappu,
It’s hard to say what the problem is without more information. I’m guessing that the problem is the format of your data. Make sure that each level of your hierarchy is an ArrayCollection so that you can filter it; arrays or anything else won’t work.

Jeff,
I haven’t figured out a solution to the bug mentioned, although I haven’t tested this code with any of the recent SDK updates. There is a comment above by Icemaker that provides a work-around for this issue. Until a better solution is found, that should do the trick.

Did you ever figure out that bug from the 2nd response?
