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 am developing a panel in Photoshop with Flex and Extendscript. I am pretty close to getting this to work, but with my Flex skills I am having a little issue with the Array I am pulling in from the jsx file. The array is displayed fine in the alert box, but somewhere between my split and creating new collection something is wrong.
Here is my Flex
protected function loadData():void {
var grabFolderNames:SyncRequestResult = CSXSInterface.instance.evalScript("labNames");
var list:String = grabFolderNames.data;

I have a Flex tree with an ArrayCollection as data provider. The ArrayCollection is composed by objects linked eachother by the "children" field (that is an Array containing other children objects)

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>
I want to load data from a external XML file, using a HTTPService, and on the ResultEvent of the same HTTPService i want him to populate a ArrayCollection with the data from the XML.
I think a ArrayCollection is the ideal for this XML.

I use this arrayCollection to populate a Flex 3 Datagrid. I'd also like to use this arrayCollection to populate a comboBox with the Name node.
In the arrayCollection, I've got the Name listed twice. I've got two rows in the Datagrid.
If I set the ComboBox's labelfield to Name, then the Name will be listed twice in the ComboBox menu. Is there a way to use this arrayCollection and have each Name listed only once in the comboBox?
I can always make another loop and array collection for the Name, but I was wondering if there were a better way.
var i:uint;
for (i=0; i<myArray.length; i++){

Is there a way display the display list in the Tree component. I could parse the display list into xml but then I would not be able to create a reference to the display object.

Given there is no tree component in Flash CS3, I used the following tutorial [URL] and managed to populate the tree from an xml file. However I am now finding it difficult to perform certain actions such as:
- adding/deleting items from the tree
- save tree back to xml format
- copy child nodes from one tree to another
here is the xml data :
<root>
<recommendedMaterials>
<value label="Aluminium" data="0" />

The problem is that the whole xml gets populated. I just want the labels. :(

I'm working on a flash cards application and am using an ArrayCollection of Objects to store each cards individual data. When the user click the 'save' button, the text from the two textAreas and the 'title' textinput are stored in the AC as one object with .title, .side1 and .side2 properties that contain the text from the flash card. I have made a List in a separate class I want to have display the title of each card the user has created, but after days of researching and looking around, I still cannot get the display to list the titles.

I have flat data in my app which I will need to group, summarize, and count as I normally would with a sql query. For this project though, it must be done in the flex app. I need to figure out how to group my data by day or month using a datatime field in my Arraycollection, then appropriately count or summarize data in other fields. I've used Groupingcollections before, but only when binding to hierarchical controls (like AdvancedDataGrid and Tree), but I need a resulting ArrayCollection with the grouped and summarized data. Basically, I'm trying to access my AC like a sql table (GROUP BY MONTH(datetime), COUNT, COUNT(DISTINCT(), etc.) and I'm unsure how to do it.

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 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:

I have an ArrayCollection bound to an editable DataGrid, another component needs to know when the ArrayCollection changes (as a result of changes in the DataGrid) so it can also update itself, so is listening to the COLLECTION_CHANGE event of the ArrayCollection.
The problem is that the DataGrid only updates the ArrayCollection when the row being edited losses focus. This is not good for my app as a user could edit a column on a row and not click elsewhere on the table for a long time (causing the row to lose fucus), therefore the changes won't have propagated to the other parts of the application.
How can I make the data grid inform the ArrayCollection of a change every time there is a keyup event on a text input instead of every time a row looses focus?
I have an ArrayCollection of Objects. Each Object with three attributes:CustomerID, Income and DateMy goal is to chart this data for each customer (or a couple together) in a Income by Date LineChart display. Selection of customers is done with ArrayCollection filters.Data is fetched from an SQL database, however, each customer has some data points missing.f there was zero income on August 8, 2010 there will be no entry for that.Charting the ArrayCollection as is, is misleading because there is no indication of the missing data points.One way to solve this is to artificially add zero points for the missing dates for each customer. However, this would explode the data set (and impact performance).

The problem lies in the fact, that when the ArrayCollection _data is filtered (because the Checkbox "Even" is set), then the 2nd loop in the test case (for adding new items) adds items (the "35") again and again - because it's filtered and thus not visible.
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?
View 2 RepliesI'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?

I have a component where I expose the property 'questions' with the following code:
private var _questions:ArrayCollection;
private var questionsChanged:Boolean;
[Bindable("questionsChanged")]
[Code]....
In this component, I use commitProperties() to implement my logic.
I use Cairngorm and the 'questions' is in the model and hence it's defined as a source for data binding.
When the 'questions' ArrayCollection's size changes elsewhere in the application, it is not invoking the setter method in the component that is destination for the data binding.
Does anybody tried Dynamic column grouping using Hirarchical/tree data structure in Flex advanced datagrid ? is it possible to create a column header dynamically and so the datagrid column with using certain datafield using dataprovider dat.
