[flexcoders] Re: Flex2 Tree Bug crashes browser

2006-02-27 Thread sufibaba 
Hi Matt,

The node has not been added anywhere else.  I've modified the Tree
example from the Flex Sample Explorer to duplicate the problem I am
having in my App and it is exhibiting the same behavior.

- tree.mxml 

?xml version=1.0 encoding=utf-8?

mx:Application xmlns:mx=http://www.macromedia.com/2005/mxml;
creationComplete=srv.send()

mx:Script
![CDATA[

[Bindable]
public var selectedNode:Object;

[Bindable]
public var XLC:XML;

public function initList(event:Event)
{
XLC = event.target.result;
}

public function treeChanged(event:Event) {
selectedNode=Tree(event.target).selectedNode;
}

public function  addNewNode() // 
{
//var myXML:XML = model.templateLayout.treeData;


var newItem:XML = node label=new node/

var newNodeAdded:XML = selectedNode.appendChild(newItem);
//Alert.show (Tree changeEvt :  + newNodeAdded.toXMLString());
selectedNode = newNodeAdded;

myTree.selectedNode = selectedNode;
}



 ]]
/mx:Script

I tried both IE and Firefox on winXP and this bug crashes both
browsers when a new node is appended to a leaf node.

Is there a possible work around for this bug do you think?

Cheers,

There's certainly a bug in here, but you can try replacing the
appendChild call:

  var newNodeAdded:XML = selectedNode.appendChild(newItem);

with:

 selectedNode.insertChildBefore(null, newItem);

Also, I changed selectedNode to type XML from Object.

This works for me, the Tree see's the update and converts the leaf to a
closed branch with the new node.

Let me know if you'll still have problems.

Michael,

Your Antibug spray did the trick.

Thanks for the tip.

What you're doing is correct, so this is probably a bug.  If we find a
workaround I'll post it. 

Thanks,

 Hello,
 
 I am writting this more as a comment then question.
 
 I have spent 2 days experimenting with the mx.collections classes
and it has
 been fun. Now, I have a project where I need the tree's root to be;
 
 ClassPaths
-  c:/classes
  -  dir structure
-  c:/mm/classes ...
  -  dir structure..
 
 I am loading all the xml tree structure form php fine. What is the
method
 for creating the root now ClassPaths ONCE, then on each new
'loadCLassPath()
 call, add the new xml to the CLassPaths root node.
 
 I have almost got it but, the tree gives me node opne errors after I
get 2
 nodes inserted.
 
 Am I doing something wrong?
 
 
 protected function loadDir(evt:ResultEvent):void
 {
 
 var newList:XMLList = new XMLList(evt.result);
 
 if (dataProvider == null) {
 
 dataProvider = classpaths label=Class
 Paths/classpaths;
 }
 
 dataProvider.source[0].appendChild(newList);
   }
 
 Peace, Mike
 
 PS the error when click to open the root node is...
 
 TypeError: Error #1010: undefined has no properties.
 at mx.controls::Tree/setIsOpen()
 at mx.controls.treeclasses::TreeCellRenderer/disclosurePress()
