Re: [flexcoders] Re: How to refresh a tree

Wed, 23 Aug 2006 16:22:31 -0700

Hi,

There is some issues with the Tree and XML dtat provider collections.

One thing I can suggest is;

Add an event listener to the divider bar release, I can't remeber what it is, in that handler call

myTree.invalidateList();

Give it a try and let me know.

I have the same issues with using itemRenderers and changing some internal data specific things. After I am done with my process, I called invalidateList() and it did a nice redraw quickly.

There probably is just an update isse and measure() is not being called correctly.

Peace, Mike

I too have had problems with XML nodes in tree. One thing that eliminated a lot of the issues was reassigning the dataProvider of the tree explictly (right after you update the node.

so...
[Bindable]
private var xmlN : XML ....
private function updateTreeDataProvider : void {
 //code that updates xmlN
   treeNav.dataProvider= xmlN;
}

<mx:Tree id="treeNav"

This is flaky, might be a bug.

-c
--ca
--cb
--cc

say the last server retrieval got ca, cb and cc. but the tree did not
show a scrollbar. this tree is in a vDivided box, so when i move the
divider upto b, i see a scrollbar, but when i move divider to cb or
cc, ca-cb and cc disappear and no scrollbar.

bug? or am i doing something wrong? i think that the tree should be
refreshing when i do such operations.

thanks.
