I am trying to get the drop down list of combobox by using a php file. That php file returns an xml string which has been used as data provider for combobox.I followed this thread too but in vain.DetailsI have set the creationComplete attribute of mx:Application to init(). In the init() function i have sent the following HTTPService
<mx:HTTPService id="interfaces" url="interfaces.php" resultFormat="e4x" method="POST">
</mx:HTTPService>

It might be something simple I'm doing wrong.I have an array populated by XML in a function by doing the following inside the function:
first_special.addItem({label: xmlMenuFile.item.headers[i],data:
xmlMenuFile.item.descriptions[i],data2: xmlMenuFile.item.hints[i]});
The problem I'm having is trying to figure out a way so that the "data2" will fill the text field "hint_txt" on ROLL_OVER of that items name in the list.I've tried to placing an event listener into the function that populates the combo box .this populates the combo box label and data with the Loaded XML File. This works
function changeHandler(ev:Event):void
{
menuText_mc.heading1_txt.text = ev.currentTarget.selectedItem.label;[code]......

I have two combo boxes. The first combo box's data is added through an XMLConnector object, the second combo box, I would like to populate through an on (change) event in the first combo box. The items in the second combo box would relate to the selection made in the first combo box.
I have attempted the following within the Actions for the first combo box:
on(change) {
switch(this.value) {
case "value1":
comboBox2.addItem({Label:"Label",Data:"Data"});
break;
} // end switch
} // end event
which is not working.
should an event be dispatched by comboBox1 and a listener be attached to comboBox2? I can't find any examples of this on the internet.. but i might be using the wrong search terms.

The flex DataGrid colums are arranged alphabetically by default. I need to order the DataGrid colums as per the order in its dataProvider. The dataprovider is the result of the HTTPService . And the number of columns is not known to us . The number of columns depends on the HTTPService result.

I am creating the standard "Click to add row" control but I really don't want to dirty the dataProvider with a "placeholder" since it is bound to the model and could end up in the database. Is there a way to add a row that isn't represented in the dataProvider? I started down the road of adding an item directly to listItems but then that needed an item in rowInfo and then that need a reference in rowMap.

I'm using a HorizontalList control with an XML file as a data provider. This is how the XML looks:
[Code]...
I tried using an array of objects as a dataprovider. The item renderer works and the horizontallist behaves as I expect it to. However, when I use an xml file, it's empty.... I don't know why it's not working.

I have a project that was compiled with the Flex 3.2 SDK. One of my components is a combobox, which is bound to a property (called products) in the Cairngorm model. If I insert a new value into model.products, then the combobox immediately shows the new value. Works perfectly.
I then moved to the 3.5 SDK, and running the identical operation causes a problem. Even though the model has been updated (I have verified that this is definately the case), the combobox does not show the new value correctly - it seems to be aware that there is a new item because there is a new row in the combo, but the new row is blank and unselectable. The existing items in the combo are there and selectable (as they should be). If I re-initialising the form (i.e. close and re-open the TitleWindow on which the combo is located), then all the correct values (including the new one) are shown in the combo.
I have swapped back and forth a few times between 3.2 and 3.5 to verify that this is indeed the root cause.

What I would like to do is simply add to a dataProvider, but when I do, I get an error. Here's the code I'm trying to run...
dg.dataProvider.addItem(obj.ResultSet.Result[i]);
It's inside a for loop, using i as the integer. It works great doing...dg.dataProvider = obj.ResultSet.Result But that won't work for me, because I need to add to the dataprovider more than once. I'm getting results in batches of 10, and I need to add each batch to the dataProvider when it's received. I also tried to to do...
var dgDP:dataProvider = new dataProvider(); But for some reason Flex doesn't recognize it...

I'm implementing some kind of combobox control (by extending spark.components.supportClasses.DropDownListBase)
Now, inside this control; I need to know:
If the dataprovider is changed/assigned. (which I can do... the first approach below works); if any item in the dataprovider collection has changed.
I tried 2 methods that did not do the trick...
1ST APPROACH:
2ND APPROACH:
UPDATE: Edited above.. The first approach lets me know if the dataprovider is changed but not if any item is updated in the dataprovider collection. The second approach does not work at all..

I've got a model class with a bunch of Number variables that change frequently. They all dispatch their custom events, thus are bindable. In my UI, a couple of those class instances are bundled into an ArrayList that serves as the dataprovider for a Spark DataGrid. The class variables change perfectly fine, so problem there.
What I'd like to do now is to change the color formatting of those numbers (the corresponding labels in the gridcoloums to be exact) depending on the data that comes in, so to say change in green when the new value is bigger, change to red when the new value is smaller than the old one.

I have a list object and I'm adding items to it with addItem through the dataProvider.Before adding an item to the list I want to make sure it's not a duplicate. I've tried using indexOf on the dataProvider and it returns null. I've tried casting it to an array and it works, but always returns -1 even if the element exists in the dataProvider.The only method I've been able to use seems a little hacky and I'd like to know if there is a better way to find an element in a dataProvider.

the dataProvider 'data' updated itself every 3 seconds, so every 3 seconds that is a flicker of some sort, i see for a really short time an empty area and then it gets redrawn again. is there a way to make the update somewhat faster ?

I've got a couple trees that I allow a user to drag and drop from one to another, works great except one apparent limitation. I'm picking up where they drop it in the list and adding it to the dataProvider manually. The user can drop it everywhere except after the last child of any particular node it seems, since it reads that position as being between the node and it's next sibling.
It seems the best way to deal with this is to add something like a dummy leaf so the user has something to drop the item in front of. I don't want this leaf in the dataProvider, so is it possible to add a leaf (or a folder) to the tree without adding it to the dataProvider?

I'm using a List which I need to be empty at the start. I'm adding items to it as needed by clicking a button. Since it's empty, I haven't added a dataProvider property
<s:List id="thelist" itemRenderer="listIR" />
To add an item, I'm adding it to the dataProvider directly
thelist.dataProvider.addItem()
but when I do that, it gives me this error
#1009: Cannot access a property or method of a null object reference.
Also I have a debugging Alert in the listIR itemRenderer itself and I see that when the list is created, I get that alert twice as if 2 itemRenderers were created, even though the list is supposed to be empty at the start.
How do I start with an empty dataProvider and add items smoothly to it?

I have an SQL Statement which I want to read the name fields from an SQL database. the code:
public function getAllGiberish():void {
var stmt:SQLStatement = new SQLStatement();
stmt.sqlConnection = sqlConnection;
stmt.text = "SELECT name FROM test3";
[code]....
This will pull the data from the db. However, in the list item it shows everything up as [object Object]. Upon debugging I can see that the data provider shows:
data[0] > name
data[1] > name
data[2] > name
Where the info that I want is the name within each data object. How do I easily access this? It is a problem I keep coming across and would like to work it out once and for all!

Let me start off by saying this is my first Flex project, so I've been reading a lot, learning a lot, but am still struggling to make this work. I am trying to display records from an SQLite database within my Flex mobile application. I have the input form saving data correctly to the database, and I have a datagrid that is outputting the records (so I can confirm everything looks good). However, my problem is making the data readable.
I want the user to be able to select an identifier from either a drop down or a list (even if it's just a 1 column datagrid), and have the labels to the right update to reflect that information.
