I have a viewstack, which contains 3 (at this moment just 1) customcomponents:
<s:Application xmlns:components="components.*">

I have a component mxml file in which i have a view stack, on click of a button i navigate to the first child, now i need to navigate to the second child during onclick of a button present in the second child. All the childs are component files included within the view stack. How could this be done, Sample code is present below,
[code]...
Now in my offering.mxml file if i try to access navigationViewStack i am getting an error stating 'Access of undefined property navigationViewStack.
I am unable to bind the selectedIndex public property of a spark DropDownList to it's original source in the view's presentation model.
For the purposes of replicating this issue with as few lines as possible I have two views, and one presentation model. The code follows.
Main.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
[code]...
Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?
I am having a real problem with one of my components. I have a list object and I need to set the selectedIndex. Now I would think this would be easy, but it appears that for just this instance the selectedIndex property is read only. I have set the property for other instances, and I can read the property for this instance, but I cannot change it.

I have a tabbar whose dataprovider is a viewstack and the viewstack contains a group of vbox containers. I am trying to hide one of the vboxes based on a certain condition but the tabbar still shows the corressponding tab for the hidden vbox. I set the visibilty and includeinlayout of the vbox to false but the tab still exists.
View 1 RepliesI have a viewstack with two tabs.In one of them there is a data grid shows a list of notes. The other one is includes a form that can edit notes or crates new note. I want the user to be able to add new note or edit existing note when clicks an item in data grid. I mean when user clicks an item the viewstack must become editor.
View 1 RepliesIn my example below, when I click "Add Content", new stack content is loaded into the ViewStack as expected. But when I then click "Close Content", I'm expecting it to close the newly created content inside the ViewStack and switch to the "defaultContent" content.

I have as good as finished a new project I'm working on now for a while, and I have this small problem coming up at the fine tuning.The area of concern is so I believe the ViewStack I'm using, but I'm not sure so here the details.I have several check boxes (4), and only one at all times can be selected to show off associated Radio Buttons as a Group of (6). No RBtn pre selected.With the selection of a check box I also make visible a new Radio Button Group of (4). No RBtn pre selected here either.Now if I select one of the RBtn (6 - each has a different Paper size measurement showing) then I can view through a external Xml data file details as Size, basePrice and the totalPrice which is in this case the same as the basePrice!
This totalPrice is located on the first Canvas/Label in the VStack!Selecting any of the first three (3) of the second RBtn Group (4) No RBtn pre selected either! - it will show me a Paper type description, and by selecting the fourth RBtn it will show me as well a field with the extra costs for a Canvas type, and it should select the second Canvas of the VStack with the totalPrice which is basePrice plus the extrasCost Canvas Price.Now the problem is that my second VStack Canvas/Label = totalPrice (basePrice +extraCost) is not showing up immediately! (It just shows blank canceling the basePrice out), and only if I select another of the six (6) RBtn! then it is showing the second vStack with the totalPrice (basePrice +extraCost). From here on everything works perfectly!I think that I have to mention that my RBtn Group are working in a function If / Else / If /Else configuration where both the Labels on both VStack Canvases are called up at the same time. So therefore both Labels should have data available which than should be viewed when the VStack changes?
I have a piece of software I'm working on that is using a viewstack with 3 canvases. With the change event I need to look for index 2 which is the last canvas when it changes to this canvas I need it to grab data from inputs from the previous two canvases.Within the viewstack events I've assigned the function change() to the event childIndexChange.
Here is the method:

In my application I have a viewstack which I am changing via actionscript using the selectedChild attribute. The problem I run into is that I want to call a method in the component that is now the selected child in the viewstack, right after I assign it to be the child it gives me a "Cannot access a property or method of a null object reference." Is there some way that I can make this work without changing the creationPolicy to all?
Actionscript:
public function displayTaskDashboard(evt:Event):void
{
pm_viewstack.selectedChild = nc_taskDashboard;
taskDashboard.populateTasks(Globals.currentProject.Project_ID);

I have created a custom component (named customtitlewindow) the code of which is as follows:
<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
[Code]....
The main purpose of mine is that for all the popup windows shown to end user all of them be closed when the escape key is pressed and all of them be closed upon click of the closebutton displayed at the titlebar.
But on the "escape key" press nothing is happening.
I have an Array Collection as follows
var myArr:ArrayCollection = new ArrayCollection([
{label: "label1", data: "data1"},
{label: "label2", data: "data2"}]);
[Code]....
How to set the selected item for myDDL based on an item id(myID)? I tried something like:
selectedIndex = {myArr.getItemIndex(myID)}
In the code below, the presentedAlbumIndex is used to control the selectedIndex of the TileList. Item "five" is initially selected. Whenever the button is pressed the first item in the array is deleted, and the presentedAlbumIndex is decremented.
In theory, the selected index should stay with "five" every time the button is clicked (until "five" is itself deleted). It works this way for the first button press. However, on the 2nd button press the highlighting changes to "six" for some reason. Also, the TileList selectedIndex is always one behind.
I tried looking into ListBase and monitoring selectedIndex. It looks like the selectedIndex is updated initially to the correct index, but then it reverts back at some point to the correct index+1. I do not know why it's setting back.
It seems it's due to the fact that I am doing a data provider delete and index change in the same operation.
Is there some function in TileList I could override to keep selectedIndex up to date?

View 2 RepliesI have a simple button function that changes the selectedIndex on a view stack without using the menu bar component. I call the function from the click property on the button and pass an int as the index I want to jump to. When I had the code on the application MXML file everything worked fine. After moving my actionscript to a separate file, I get access of undefined property errors:
protected function changeView(index:int):void

In lee's xml tutorial he uses the list component and the text area component but when he tested the swf he had to select the item befour the text field was populated.
i have set the selectedIndex to 0 but the data still does not load untill an item is selected.
Ok I can't find any doco on this and it's driving me crazy. Anyone know how you specify the default value for the V2 ComboBox component based on the selectedItem when you don't know the selectedIndex? Here's my scenario:
I have a hardcoded combobox called "dd_names" with 50 names in it. I'm returning a dataset into Flash via a SQL query, and onload I need the dd_names dropdown to default to the value of the name returned in the dataset. So if the query returns "Tom" I need the dropdown to default to "Tom."
I tried setting dd_names.selectedItem = "Tom" and dd_names.value = "Tom" and these don't work. The ComboBox just defaults to the first item in the list.However, if I use the selectedIndex property and set dd_names.selectedIndex = 3, the ComboxBox doesn't default to the first item in the list but shows the appropriate item. This doesn't help because I don't know the selectedIndex being returned from the query - I only know the selectedItem. Anyone know how to do this??
I have a custom component in a repeater. This component has a child component which can be of two types depending on some conditions. [coed]...
When I place breakpoints in the functions called at creationComplete, I can see that the component assigned to placeHolder is correct but it does not show on my display. I tried refreshing by calling invalidateDisplayList in every place I can think of but it does not seem to work.
I have a DataGrid bound to an XMLConnector and XMLDataSet. The XML data loads fine into the components. However, I cannot get the value of the selected index using: my_datagrid.selectedIndex
The call works fine if you use addItem to populate the grid.
Is there an issue being that the datagrid.selectedIndex parameter is bound to the XML components?
Isn't there a better way to accomplish this?[code]...
All I want to do is make sure that when I update the item that the comboBox is pointing to internally, that it's selectedIndex also update so that the label within the ComboBox reflects the new value.

The problem is that the news_selector.selectedIndex bit is showing as undefined in the debug window, and thusly the if/else statements are ignored completely.

I have a parent file that loads and unloads swfs depending on which page of the website you are on. In the parent swf, I need to update a dynamic text field to indicate which page you are on. My assumption was that I could simply set a string variable within each child that would provide that title, but I'm having no luck accessing a variable contained within a child.
