We're currently seeing a caching corruption problem with LiveDocs in
which random files display instead of the correct pages. You'll see a
variety of symptoms:
* The wrong page displays
* Infinite loops in the TOC (this happens when LD loads a .js file
instead of an HTML file)
* Bad formatting (when a CSS file doesn't load properly)

The good news is that our web team has identified the bug that causes
this. The bad news is that they're still testing the fix and it won't
get rolled out until April 17.

I've had fairly random results over the last few days. Sometimes
changing browsers helps, sometimes it doesn't; sometimes clearing
browser cache fixes it, sometimes it doesn't. One suggestion is to
download the complete Flex doc zip file, which contains usage docs in
PDF and the Language Reference in HTML and access the docs locally.
This is available at
http://livedocs.adobe.com/flex/3/flex3_documentation.zip. Individual
PDFs are available from the Flex Help Resource Center page:
http://www.adobe.com/support/documentation/en/flex/

I sincerely apologize for the inconvenience this is causing.

You can call tabNavigator.removeChild( childOfTN ), but you will have
to add some extra logic to make sure it gets added back at the same
position.  (Calling addChild( childOfTN ) will place the tab at the
far right side of the list)  Plus there is some overhead in adding and
removing the contents of your tab...  It might be easier to swap your
TabNavigator out for a TabBar and ViewStack.

Sorry for changing the subject here. I am actively searching for a
Flex guru for an elite Investment Bank in NY, if you know of anyone
who might be a good fit, please feel free to pass my information and
job description along. If job postings are prohibited on this board
please let me know and I will remove the message.

One of the world's leading investment banks is searching for strong
front-end developer for their front office Equity Trading Systems
team. This person needs to have at least a years worth of FLEX
experience. You will develop Front End / Middle tier Application
using a combination of Flex / Java. Application is used to display
and modify algorithmic trades that have yet to take place. Position
requires good communication skills and ability to learn advanced
business functions. Flex is the most important skill set. Java his
desired as well.

Required Skills: Adobe Flex and solid understanding of web
architecture and scripting languages Actionscript/Javascript - Adobe
Flex - Sybase - SOAP/XML

Pluses: Java, financial experience.

I got fed up with Adobe taking away this ability in final AIR beta and
not putting it back in for AIR 1.0.  It's perfectly logical that you'd
want to use the Flex DragManager inside your app to have control over
the drag proxy alphas and such, but not lose the ability to do Native
drag operations in the same AIR app if you so choose.  I've detailed a
MonkeyPatch solution to this problem in an example on my blog.
View-source is enabled on the code.

Do you know any other way to get the height of the element in the row?

Since variableRowHeight is true, if i could do some kind of getChildren() or
something, I
could get the height of each child .. :x

I have a canvas (as a PopUp Window) which gets a swf applied as a
backgroundImage source. This canvas subsequently may get decorated
with new display object children which are editable by the user.
Objects are placed on the canvas at specific locations manually or
programmatically based on content in the canvas backgroundImage.

The problem I am having is that the display is consistent on my PC
running XP, FireFox, Flash Player 9.0.045 with the canvas popping up
displaying the swf as background scaled at 100% filling the canvas
proper.

The issue reported by others on staff using new MacOSX Leopard, Safari
and Flash Player 9.0.115 is that the backgroundImage is much larger
than 100% and not fully visible and is cropped off by the canvas. This
canvas is adjustable in scale but changing scale makes no difference,
background is still bleeding over.

The canvas and backgroundImage size / scale are all set using an
Override....Is this a bug or is there some better method to achieve
the same results more consistently.

I have a menubar setup and working perfectly with XML.

I would like to recreate this menubar using objects retrieved via
AMFPHP. I have setup my service in AMFPHP and it is returning the
objects properly. The problem is that when I set the menubar
dataprovider property to the arraycollection returned from AMFPHP, my
menubar is empty.

Is there any example code anywhere that uses objects instead of XML?

Has anyone tried this before?

Also the XML is an XMLList, not an XMLListCollection..
Is there a work around?

Thanks for helping. I still can't get it.. Nothing displays in the tree now.
I thought maybe it was due to the isvisible being a 1 or 0 (but I'm
sure Flex/AS knows that it's boolean value).
Anyways I tried 'true' and tried '1'. I even reversed them thinking
that perhaps there was something wrong with the value.

I even tried adding an Alert
Alert.show(col.toString());
and I got about 4 empty Alerts.
So I wonder if it has to do with the time it's loading?

The xml coming in looks like this..
<node activity="LOA_Sick" label="LOA_Sick" isvisible="0">
	 <node activity="LOA_Sick" label="Sick" isvisible="0"></node>
	 <node activity="LOA_Sick" label="LOA" isvisible="0"></node>
</node>

and it's loaded in the model (using Cairngorm)

Yes, that appears to work. Thanks!

What's the difference between dataProvider="[]" and
<mx:dataProvider/>?

Does anyone know where to find an updated and working version of
dhtmlnirvanas audioManager.as?

Question, I know that by default <mx:List> is scrollable, and if the list has
content with
height that adds up to a height greater then its own height, it adds scrollbars.

My question, and I have had this question many times in similar situations, is
this:

Code (Simplified Overview):

<mx:Canvas width="100%">

<mx:List width="100%"
dataProvider="{dataProviderHere}"
itemRenderer="{itemRendererHere}"
/>

</mx:Canvas>

Problem:

When data is pushed into the list, I want it to resize the entire list, and by
doing so, resize
the height of the canvas that is it's parent.  I do not want it to add
scrollbars, which
verticalScrollPolicy can turn off.

Halp! :(

Hi All,

   I am using the Derived class of DataGrid which is given in one of
the posts in this Forum ( which i copied at the end of the post) and
when i try to run my sample i am getting the following Error:

[ERROR]
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

In my Panel i have the following code to display the Grid..

[CODE]

<mx:script>

  var contextNode:Node = null;

private function setRowColor(data:Object, color:uint):uint{
				 var tmpNode:Node = null;

				 if(contextNode!=null){
					 tmpNode = Node(data);
					 if(tmpNode.nodeId==contextNode.nodeId){
						 return 0xFFFF00;
					 }
				 }
            	 return color;
         	 }

         	 override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void{
				 super.updateDisplayList(unscaledWidth,unscaledHeight);

				 var m:Matrix = new Matrix();
				 m.createGradientBox(unscaledWidth,unscaledHeight);

				 var g:Graphics = graphics;
				 var colors:Array = [0x0000CC];

				 g.clear();
				 g.beginGradientFill(GradientType.LINEAR, colors, [0.2,0.6],
[0,255], m);

				 // the rectangle is drawn a little high and a little tall to
compensate for the gap
				 // the DataGrid introduces between rows.
				 g.drawRect(0, -2, unscaledWidth, unscaledHeight+4 );
				 g.endFill();
			 }
</mx:script>

and the RowColorDataGrid Code:

[CODE]
public class RowColorDataGrid extends DataGrid
	 {
		 public function RowColorDataGrid()

			 super();
		 }
		 private var _rowColorFunction:Function;

		 public function set rowColorFunction(f:Function):void
		 {
			 this._rowColorFunction = f;
		 }

		 public function get rowColorFunction():Function
		 {
			 return this._rowColorFunction;
		 }

		 private var displayWidth:Number;

		 override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
	    	 {
	    		 super.updateDisplayList(unscaledWidth, unscaledHeight);
			 if (displayWidth != unscaledWidth - viewMetrics.right -
viewMetrics.left)
			 {
				 displayWidth = unscaledWidth - viewMetrics.right - viewMetrics.left;
			 }
	    	 }
	     override protected function drawRowBackground(s:Sprite, rowIndex:int,
												 y:Number, height:Number, color:uint, dataIndex:int):void
	     {
	    	 if( this._rowColorFunction != null )
	    	 {
	    		 if( dataIndex < (this.dataProvider as ArrayCollection).length )
	    		 {
		    		 var item:Object = (this.dataProvider as
ArrayCollection).getItemAt(dataIndex);
		    		 color = this._rowColorFunction.call(this, item, color);
	    		 }
	    	 }

	    	 super.drawRowBackground(s, rowIndex, y, height, color, dataIndex);
	     }

	 }
[/CODE]


Initially i had the updateDisplayList() function in RowColorDataGrid
and even then i had the same Error.!!

I am not sure why i am getting the Error:

Thanks
Mars

Is it working?
