I'm a Flex noob and I've been struggling with this problem for a last week, and I'm at my wits end.
I have opened the following XML file
<root>
<person>
<city-of-death>asdf</city-of-death>
<place-of-death>qwert</place-of-death>
</person>
[Code]...
I would be so incredibly grateful if someone could help. I am pulling out my hair!
I have a List, that is not showing any items until you scroll, then the items show up. Does anyone know how to fix this? I tried calling list.invalidateDisplayList(); and list.invalidateList();
EDIT: Here is some code:

I found that if I add creationComplete="{list.dataProvider = _xmlList }" It solves the problem.
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.
Part of my NewCard.mxml:
<?xml version="1.0" encoding="utf-8"?>
<fx:Script><![CDATA[
import flash.events.EventDispatcher;
import mx.collections.ArrayCollection;
import spark.effects.SlideViewTransition;

I want to create a list of progress bars and update the list accordingly.I have group data in an Array as
<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....
The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as
<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>
Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").
I seem to have is that the Autocomplete component that seems to be part of flex extras is not displaying the list of items in the dropdown list. Basically, I get a list of blank items. I know they are there and they are the right items because as soon as I click on one, I get the right text in the combobox.
my Code in the mxml looks something like this
<mx:FormItem label="Company:" width="750" fontSize="20" horizontalAlign="right" color="#000000" required="true">
<ns1:AutoComplete enabled="true" labelField="CompanyName" textAlign="left" dropdownWidth="450" id="txtCompany" width="450" />
[Code]....
Again, when I type "T" in the text box I see a dropdown list with 3 empty items. Clicking on the third item puts "Test3" in the textbox. But the items themselves are not visible.
It almost as if its a font/foreground color thing, but I've played around with some of those settings too with no success.
Im currently creating a list in Adobe Flex/Actionscript for a person search app. At the moment, the list shows 1 line of text:

I have an issue with Spark Lists whereby I am trying to ensure that an item is always selected and ensure that the GUI displays this to the user.
The application (full code below) creates a List, a Label and a Button. The Label states what is selected in the List. The button removes the selected item. Changing the selection, updates the text in the Label. Important: The List has "requireSelection" set to true to ensure that an item is always selected.
If I select the first item in the List, the selection is correctly reflected in the label. Clicking "Remove" removes the item and the next item is selected. This is all working correctly.[code]...

What is the role of source for an ArrayCollection or XMLListCollection? Is it used just once - when constructing a new ArrayCollection or XMLListCollection object and is it copied to some internal data structure of that object?
Because nothing is updated when the source Array (or XMLList) is being modified and the documentation confirms it too: The underlying XMLList for this collection. The XMLListCollection object does not represent any changes that you make directly to the source XMLList object. Always use the XMLListCollection methods to modify the collection.
This property can be used as the source for data binding. When this property is modified, it dispatches the listChanged event.
I'm asking because Flex examples related to dataProviders always use some Array or XMLList as source of data for a data-driven component. And I wonder, if using Array or XMLList is necessary at all - when for example loading data from external PHP-script.
When the XMLListCollection is updated in the DataGrid, I want it to add the XML (bind it) into the Model. How would I do this? Or if not possible, how would I manually add XML into the Model?
This is a rough example of what I'm trying to do. Adding data to the DataGrid works fine; it just doesn't go into the Model when sending to the HTTPService.
<mx:Model id="model">
<root><colors>{collection}</colors></root>
</mx:Model>
<mx:XMLListCollection id="collection" />

I am trying to display content of xmllistcollection in different fields in my datagrid however unless I use an itemrenderer the value is not displaying in the grid. The xmllistcollection is populated from a webservice call. Inside my item renderer i use a custom namesspace to retrieve contents from the xmllistcollection
value.ns::firstName
However if I try something like
dataField = "ns::firstName"
In the datagrid without using an item renderer I get no data output.
I have a requirement of sorting the <ename> in the XML with in the branch. The XML goes like this:

Is there anyway of type casting an ArrayCollection to xmllistcollection or to xmllist or can we covert ArrayCollection to xmllistcollection or to xmllist?

Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?
(I'm using Cairngorm)I have a combobox that displays items form an XMLListCollection that's in my model.I want to only view the items (XML) whose "sent" properties is false.. like item.sent == 'false'.This filter must apply only to this specific combobox, not everything that's bound to the XMLListCollection source.And of course it must update and refresh the filter if the source changes..I'm trying to use filterFunction but don't understand how it works...

Since my original post got moved to Components thread, but no one is responding and the majority of the people on the Forum are here, I'm gonna repost it here. I have an AS created List Component that is dynamically populated using a dataProvider populated from an XML document. When I addChild to the main timeline, everything works. When I addChild it into a MovieClip, the list shows up with the appropriate number of rows, but no text.[url]...
View 0 RepliesI would like to have a List displayed that displays data collected from the user into an ArrayCollection. I have a main DataHandling.as class that "adds" the data to the AC as an Object, but when I use trace() on the AC from another class, it does not show any values being present in the AC.
I also added some test data to make sure I was populating the AC correctly and that works just fine. I just can't seem to figure out how to add data (text specifically) to the array from another class. (The other file is .mxml)Here is my mxml code (MyCards.mxml):

protected function myCardsList_creationCompleteHandler(event:FlexEvent):void

I have a Flash page that goes out and reads an XML file, then displays the information in it. Most of the time, it works great. However, when it comes to nested lists, it doesn't work. I am using CDATA so that I can use HTML code to display the information as intended. But Flash absolutely refuses to display a nested list correctly. For example, if I put in there <ul><li>item 1 <ul><li>subbullet 1</li><li>subbullet 2</li></ul></li></ul>, it displays everything as if I had made each of them individual list items under one master <ul></ul>.
There's got to be a way to get Flash to understand and display a nested list. It's a simple thing to do, I know it.
I have a screen which is essentially an address screen. Amongst other fields. there are two fields on the screen which are used to enter the region of the user. One is a combo box, the other is a plain text field.
After the user selects their country from a drop down list, if that country has a list of regions associated with it, a Combobox is populated and displayed, with the text field being hidden. If there are no regions associated with the country then the combobox is hidden and the text field is displayed:

I am trying to create a thumbnail viewer using a list component. I used list.cellRenderer to display a test image and it displays that image about 50 times vertically down the list component. how to use this component with images?
View 1 RepliesI am an inexperienced user of Flash CS4 Pro (v10.0.2). I am attempting to use the List component with ActionScript 3.0 to make a different image display when a user clicks each item in a list. I did find a tutorial that showed me how to make different text display using a dynamic text box and the following ActionScript:
[code]...
...where My List is the instance of the List component and ListText is the dynamix text box. In this case, the user clicks an item in the list, defined by the label value in the dataProvider parameter of the List component, and text displays as defined in the data value in the dataProvider parameter.
However, as I mentioned to start, what I really want to do is make images display instead of text. Can anyone provide me the steps to do this?
the embed fonts stuff in flash, it sometimes works and then again it does not. my problem I need to embed a greek font to be used with the List Component. what I did so far:
1. library-> new Font ( Named it myFont, exported it as:MyFont )
2. put a list comp on stage called it myList
3. got a xml file called index.xml encoded in UTF-8 (so it displays greek chars) that gets loaded (makes no diff if you use component inspector to insert the labels)
4. set system.codepage to false;
Code: Select allmyList.setStyle("embedFonts", true);
myList.setStyle("fontSize", 13);
myList.setStyle("fontFamily" , "MyFont");
what it does not work. I am at a loss as to how to get this to work. I am attaching the file and the font used. (verdana arial should work too, but even they don't embed)
Mabe it has something to do with the xml encoding, but if you try to just copy the greek characters into the component inspectors lable field they are still not displayed. So I guess xml encoding is not the problem.
In a kind of image browser where navigation is done through keyboard's arrow keys, I get the case where the user keeps the finger pressed on the arrow key. There, the list scroll faster and the screenshot doesn't have time to draw that the next item is already called.
I can see that in that case the CPU goes from an usual 1% when browsing "gently"..to about 20% when leaving the arrow key pressed and raging through the list of images.
I was thinking to:
1) Force the scroll rate to max out at 10 items per second
or
2) Only show pictures if key downs are > 10fps
or
3) Find a function that would wait for the last image to be drawn before continuing in the list.
So, to summarize:
- how to skip drawing pictures if the list is browsed to fast...or
- how to force the script to wait for the current image to be drawn before passing to the next item...or
Here is the script part containing the PNG loader, I've the feeling that this is the place where such a "limiter" should take place:

The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.
