ActionScript 3.0 :: Flex Missing Tree Data
Dec 2, 2011
I have component with Trees and I'm moving elements from one to another. I store data in dataProvider as XMLList with labelFiled="name" and itemRenderer as class, which expends one (thanks to that nodes and elements have checkboxes). I enabled moving mechanism between Trees just by enabling Tree's properties (dragEnabled="true" dragMoveEnabled="true" dropEnabled="true"). Problem occurs when I try to get data from dataProvider, which has only elements. To get data I use command:

Let's say I had an ArrayCollection like this:
public var ac:ArrayCollection= new ArrayCollection([
{item:"dog", group:"Animals"},
{item:"orange", group:"Fruits"},
[Code]....
How would I create a Tree component in Flex 3 that uses the groups as nodes, with the appropriate items listed under each node?

I have a requirement to filter the tree similar to that of flex builder-->preferences wizard tree.
My tree dataprovider is arraycollection of industries. Each industry has a list of sub industries and further, say upto depth 5.
So when we type in a string to filter, only the node having this string along with their parent hierarchy should be returned.
How can we implement this using flex?

I have an actionscript-instantiated component in a containment hierarchy; it extends ComboBox, but it's instantiated dynamically--you never know when you're going to need it. Somewhere up in its containment hierarchy, there's a thing which extends NavigatorContent which logically is the right place to put the valid values for said combo box. What's the canonical way for that child component to get a reference to that set of valid values?

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

I have a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?

This is my XML data in a file named nodesAndStuff.xml.
<?xml version="1.0" encoding="utf-8"?>
<root>
<node label="One" />[code].........
Now I have added my tree just below the list and I have saved counting from 10 to 19 in one.xml, 20 to 29 in two.xml and so on in different XML file. I have no clue how to connect the XML containing counting from 10 to 19 as the single node in tree at the selection of label one in list

I have been using Uploadify in my PHP application for the last couple months, and I've been trying to track down an elusive bug. I receive emails when fatal errors occur, and they provide me a good amount of details. I've received dozens of them. I have not, however, been able to reproduce the problem myself. Some users (like myself) experience no problem, while others do. Before I give details of the problem, here is the flow.

having a really frustrating problem. I have a file, originally penned by anoother developer in CS3 and resaved as CS4. It uses datagrids extensively. When clicking on a cell in a data grid it now fails to render the font (or a blinking carat for that matter). When you click off and finish the edit the text you enter is there, of course that isn't much use because you can't see what you're typing.I haven't changed how these grids work in anyway, and it was working in CS4 before *mysteriously* stopping.Have tried setting the font to one that is embedded in the setStyle of the custom renderer the cell is using but it makes no difference - everything renders fine when not editing but disappears when editing.

I have been trying to populate a tree control via an httpservice that uses php to talk to a database. The queries work fine and the data comes back in the following format from php:
echo "<root>";
echo "<topic>";
echo "<sectioncode>$sectioncode</sectioncode>";
echo "<children>";
echo "<labtitle>$title</labtitle>";
echo "</children>";
echo "</lab>";
echo "</root>";
Flex can see this and interprets the heirarchy fine unless i try to format the resultformat in the httpservce (if i do that it goes a little nuts). The results from the php query to the db come back as an ArrayCollection with each containing a "root->topic->sectioncode->title" type of structure (which is what I want). When I go and try to use this Arraycollection as a dataprovider for a tree control, it doesn't work at all. When I use the arraycollection as the dataprovider I get [object,object] for every row in the tree and there is no parent/child structure.
Ideally I would like the title to be a child of the numbercode, but when i try and format the return from xml like that the number becomes and object without a value and the title becomes a child. I have a feeling that I am missing something in the php return to show the structure to flex more clearly and also something in the tree to implement it as the data provider better. Here is the code that I am using in the tree:
<mx:Tree x="25" y="48" height="451" id="ilabtree" dataProvider="{labarray}" labelField="@title" width="152" textAlign="center"></mx:Tree>

The problem is that a cannot acces the nodes in the tree using AS3 syntax. My guess is that the problem is nhe namespacing that is making it impossible. I have been sitting for hours trying to set namespaces or removing them, but i just cant get this to work. I can load the XML, but as soon as i try to walk down the tree i get no data output. Here is my actionscript so far:
var myNamespace:Namespace = new Namespace( "http://www.w3.org/2001/XMLSchema-instance" );
default xml namespace = myNamespace;
var xmlLoaderAvdelningar:URLLoader = new URLLoader();
[code].....
there is no way for me to acces one of the nodes in the tree and trace the data. To me the namespacing in the XML is very confusing, and i have no experience working with this kind of XML

I have been given the task at work to create a interactive tree. A little like a family tree, but instead of people it will be branches (think of them as buildings). I've spent a day or so looking and finding out how to get the data from my SQL database in a format that flash can read it etc. Anyhow the problem is I don't really know where to start with the graphical aspect of it...
Each branch can have more than one child and i want the user to be able to scroll through the history of that branch, seeing it's parent branch and also it's child branches, each branch will have a certain amount of information to show. So it's almost as if i need to create a branch class and then use this and load all the data into it etc.
Should i create a new layer for each branch? Then when the user clicks a down button i just take them to a new layer? Do i create the whole thing on one layer and have navigation buttons so the user can scroll around the window and see all the other branches?
It would be nice if i could draw the damn thing at run time, and the user almost walks along lines from one branch to another, and has the option which path to take if one branch has more than one child etc.

Goal: load XML data (it parses automatically), parse through the XML tree and assign the values to an array of my choosing for access later in the movie. Problem: I can load the XML data, but the only time I can access the XML functions, i.e. XML.firstChild, or XML.getChildNodes(), is when I am within an XML.onLoad function.

I have a intro to a picture of a tree which has buttons on it. The intro is an embedded flv video (not using the FLV component). The video starts on frame one and runs to frame 2. The tree is on frame 3.When I click a button on the tree, it runs the respective frames then returns to the tree. When the tree appears, the sound of the video is playing in the background.How can I make this stop?
Code:
stop();
MovieClip(lion_mov).stop();
//video Mouse Click[code].....
Frame 3 just includes all the mouse clicks for the tree.

I just set up my environment (Flex 4.6 SDK, Blaze DS 4.01) and I'm wondering where the needed mx.* packages might be found, since I want to import classes, such as mx.messages.Producer / Consumer, in my non-MXML-Project and instanciate them programmatically. Blaze DS API ref says, they are part of the Blaze-WAR but I just can't find them.

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.

I had Flex Builder 3 installed and working properly.
I then downloaded Zend Studio 7 (Eclipse) and installed the flex 3 plugin for it. Since doing that I now have a problem with Flex Builder.
I right click on the Flex project and select "properties->build path" there are now missing options. I should be able to add project references and SWC's. These options are simply missing. I basically get a blank window instead of the options.
I have tried completely removing both Zend and Flex Builder. I re-install Flex Builder and it's still the same.
This is on a Vista Ultimate system. I have tried running the installer as Administrator.
I've been trying to find if there is a way to do a clean uninstall of Flex Builder, can't find how to anywhere.

I'd like to add copy and paste functionality to context menu in my Flex application. After creating a separate dummy project for testing, I realize that such options (cut, copy, paste, and delete) are already available in this dummy project without any coding. Both projects are compiled using Flex 4 SDK, run in the same brower (IE) and have the same version of Flash Player (10.2.153.1). However, different context menu are displayed. Here are the difference:
Orig Project: Print, Show Redraw Regions, Debugger, Settings, Global Settings, About Flash Player...
Dummy Porject: Cut, Copy, Paste, Delete, Select All, Settings, Global Settings, About Flash Player...
