Flex :: Getting Unique Elements From An ArrayCollection?

Mar 19, 2010

I have an ArrayCollection as mentioned below.

private var initDG:ArrayCollection = new ArrayCollection([
{fact: "Order #2314", appName: "AA"},
{fact: "Order #2315", appName: "BB"}[code].....

I want to populate a ComboBox with UNIQUE VALUES of "appName" field from the ArrayCollection initDG.

<mx:ComboBox id="appCombo" dataProvider="{initDG}" labelField="appName"/>

One method I could think is to loop through the Array objects and for each object check and push unique appName entries into another Array. Is there any better solution available?

Flex :: Converting Nested ArrayCollection Elements To Another Class?

Feb 1, 2011

I have an ArrayCollection and each element is an instance of the TreeNode class (a custom class made by me) that has a "children" property which is an ArrayCollection of more TreeNode elements. That way, I have a tree of elements in an ArrayCollection structure:

tree = new ArrayCollection([
[new TreeNode(param1, param2, new ArrayCollection([
[new TreeNode(param1, param2, null)],

[Code]....

But my problem is: I need to have the same "tree" structure (it doens't need to be the same variable) filled with instances of another class. How can I achieve that?

ActionScript 3.0 :: Adding Elements To An ArrayCollection?

May 29, 2009

I am having issues with this method. It's supposed to loop through stage elements (news feed) and check if the item is checked/enabled. If they are, it should add them into an array ratingAC, which will keep track of the number of elements that are rated, and the rating total. The problem I am having is that only one item is added to the total even if multiple are selected.

Actionscript 3 :: Remove Filtered Out Elements From ArrayCollection?

Sep 4, 2011

I have a big ArrayCollection variable. I want to filter it serveral times and each time assign the filtered result to a different ArrayCollection variable.

So if it has let's say people, fruits and cars. (for illustration purposes) I want to first filter it to only show people, assign the result to a people ArrayCollection, then filter it to show fruits and assign it to a fruits ArrayCollection and so on.

How can I do that? Not the filtering, but the assignment after filtering. Or is it faster to instead run a for-loop through the big ArrayCollection and just add each item into the corresponding smaller ArrayCollection?

Flex :: Mxml - Components Bound To Empty ArrayCollection At Load Time Don't Render As Expected When The ArrayCollection Is Updated?

Oct 27, 2009

I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:

<?xml version="1.0" encoding="utf-8"?>

Actionscript 3 :: Flex CategoryAxis With Non-unique Values

Jul 27, 2009

I have a BarChart that compares different user interactions with a program we have. Obviously some users will have multiple sessions and depending on what the filtering is, a single user may have multiple entries displayed at once.

The problem comes in with the Category Axis, which uses the username as the categoryField. This is fine and displays nicely when there are no repeats of the username in the dataset. If there are repeats, though, it will put a new entry in the Y axis for each instance of the username, but all of the data is rendered on the first label in the Y axis.

Is there any way to keep the username as the category axis, but have the BarChart display the corresponding data in the correct spots?

Flex :: Strategy For Making LocalConnection Ids Unique

Aug 8, 2009

I'm using a localconnection to allow communication between an actionscript 2 swf and an actionscript 3 swf.Localconnection objects share a global namespace across a user's pc.So, this means, a user can fire up my flash app in one browser, and submit commands, back and forth, which is what i want. But the user can also fire up another browser, and all commands sent to my application will be handled by the first application if its still loaded in the first browser.When I make the LocalConnection, I specify an id, but the id must be known to the actionscript 2 swfs, and therein I find a problem. I don't know how to let the actionscript 2 swfs know what the unique id is.

Flex :: PureMVC: Unique Mediator For Each Tab In An Interface?

Oct 12, 2009

I am building a tabbed interface for switching between various similar layers. Each layer will have a number of graphs. By dragging with the mouse the graphs can be rearranged or even moved between layers. My question is, is it best practice to register a unique mediator for each layer that keeps track of the layers content / organization, or should i keep track of it all with one central mediator.some considerations:

the layer contents and organization will be saved(in a db) so that it can be restored when a user comes back to the app.the layers themselves are functionally identical.the user can add and remove layers at will.

Flex :: Datagrid - ItemRenderer Flex Values Getting Not Rendered According To ArrayCollection Provider?

Php :: Zend_AMF: Get A ArrayCollection From Flex?

Sep 22, 2009

I currently have an arrayCollection in Flex and I want to sent it to PHP (Zend_AMF). According to the Zend_AMF wiki, sending an arrayCollection over directly will force Zend_AMF to cast the arrayCollection as an object which is no good. I'd rather have an array of my models. I assume the best way would be to convert the arrayCollection to an array in flex and then send it over. Is this true, and if so how would I do that in Flex 3? If you have a better recommendation,

I have built an image cache which is an ArrayCollection containing images. I have built functionality so that the cache can hold a max of 250 images. However, the images can be of a different size, so it's better to limit the total memory size of all images in the ArrayCollection. How I can get the total memory size of an ArrayCollection without looping through all the items in the ArrayCollection?

Flex :: AdvancedDataGridRendererProvider ChildrenField ArrayCollection?

Feb 5, 2010

I have a main class ClassA that has a bunch of "normal" properties that are simple datatype like ints, strings, etc. It also has one property ("childItems") that is an ArrayCollection of ClassB.I am using an ArrayCollection of ClassA as the source for an hierarchical data provider for an AdvancedDataGrid. I set the childrenField to "childItems".

I want to display some information about the list of ClassB objects in a nested table and pie chart, an AdvancedDataGridItemRendererProvider (columnIndex = 0, columnSpan = 0, depth = 2) and point it to my custom renderer which is an HBox with the table and the pie chart in it.

In order to see what is being set, I override the "set data" function in my custom renderer and what I see is that each instance of ClassB in the ArrayCollection is passed to the renderer separately.

Here is my question: I expected the whole ArrayCollection of ClassB instances to be passed to the custom renderprovider once and not each item in the child list individually. How do I make the ADG understand that the whole property is supposed to be passed as the data to the renderer and not each entry separately? Btw, when I change the data type of "childItems" from ArrayCollection to ArrayList, the whole list gets passed and I can easily do what I want to do. But based on my understanding, ArrayList is not really supposed to be used and ArrayCollection is better or at least more common.
