Thanks very much for making that but it throws the same exception when
I click on any tabs. I used your code verbatim, here's my mxml file
that loads it:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*"
creationComplete="initApplication()">
	 <mx:Script>
		 <![CDATA[
			 import NestedTabs.NestedTabs;

			 public function initApplication():void {
				 var ntn:NestedTabs = new NestedTabs();
				 this.addChild(ntn);
			 }
		 ]]>
	 </mx:Script>
</mx:Application>

Does the error happen to you when you try it?

Alright, well that didnt go so well :) I've figured out a real basic
way to mess with how BarSeries is rendered but I'm stuck...

I decided today would be a learning day and I'm tinkering with the
idea of making a Gantt Chart. So I thought I'd start with a BarChart
and have a custom GanttSeries which extends BarChart. I know exactly
what I want to do, but stumped on how to fit it into the Flex
framework....I've only messed with custom components and renderers to
this point so this is a big leap it seems to make a custom Chart. Good
time to learn right? :)

-Should I make a custom chart that extends BarChart or a custom series
that extends BarSeries? What about extending CartesianChart?
-Whats the implications and restrictions I'll get into to choosing one of those?
-How would I get access to other varibales and how should I deal with
those (I need more than just one value) - should the "data" be an
Object with values?
-If I'm extending a series, how do I get access to the values in the
extended parent? An example would be in BarSeries where it sets the
_instanceCache - if I do a super(); to run that, is there anyway I can
access that data? I found a messy way of changing how
updateDisplayList runs but I'm not sure I'm doing it correctly because
I had to redo all what the BarSeries was doing.....maybe just do a
graphics.clear and do your own thing? I'm guessing that's wrong.

Rescue me Ely the Chart Guru! :) There needs to be an example of
extending a chart or customizing a chart/series....looking through the
docs, there's a lot out there for components and renderers, but little
for chart/series. Maybe it's too rough a realm for documentation? :)

try using the arguments property. This is what my code looks like.

dmws = new WebService();
dmws.loadWSDL(MyWSDLURL);
dmws.useProxy = false;
dmws.addEventListener("result", onDmwsResult);
dmws.addEventListener("fault", doFault);

var op:AbstractOperation;
op = dmws['GetDocument'];

var args:Object = new Object();

args.EnterpriseId = event.target.selectedItem.EnterpriseId;
args.DocumentType = "EBD";

args.ContainersToRetrieve = new Array();
args.ContainersToRetrieve.push("Client");
args.ContainersToRetrieve.push("IndustryTrends");
args.ContainersToRetrieve.push("OptionalSections");
args.ContainersToRetrieve.push("RPRSelections");

args.MetadataToRetrieve = new Array("RPRDocumentHistory");

op.arguments = args;
op.send();

Let's see....

-Should I make a custom chart that extends BarChart or a custom series
that extends BarSeries? What about extending CartesianChart?

Probably you want a custom series, that either extends BarSeries or
starts from scratch.  The Chart classes generally act as a coordinating
container, but doesn't know much about what data is rendered or how it's
rendererd. That's the series' job.

-Whats the implications and restrictions I'll get into to choosing one
of those?

See above.

-How would I get access to other varibales and how should I deal with
those (I need more than just one value) - should the "data" be an Object
with values?

The way the charts generally deal with this is by assuming that the
items in the dataprovider are objects, and allowing the developer to
assign 'xxxField' properties to tell the series what property to find a
given value in. i.e., BarSeries defines xField, minField, and maxField.
BubbleSeries defines xField, yField, and seriesField. If you need
additional information, I'd suggest adding new properties like this.


-If I'm extending a series, how do I get access to the values in the
extended parent? An example would be in BarSeries where it sets the
_instanceCache - if I do a super(); to run that, is there anyway I can
access that data? I found a messy way of changing how updateDisplayList
runs but I'm not sure I'm doing it correctly because I had to redo all
what the BarSeries was doing.....maybe just do a graphics.clear and do
your own thing? I'm guessing that's wrong.

If the variable is private, it can't be accessed.


Again, if you can give me specifics on what you're trying to do, I can
help you figure out how to do it.

Hi I'm wondering if anyone has done an extended dataGrid component or
can shed some light on the direction to take on building a dataGrid
that autosizes it's columns to the size of the data contained,
similar to how a normal grid component filled with text fields would
work, but of course I need it to me sortable and scrollable, so the
dataGrid is really what I want. I'm considering trying to handle an
event when data is loaded to each cell to increase a width var if the
new value us larger, then set the column widths to that var, but I'm
getting a little bogged down with what events to attach eventHandlers
to. Any advice is appreciated, thanks!

Chris

BTW, Flex 2 Beta 2...

I have a panel that contains a viewStack with two children.  One of
the children is a tabNavigator and the other is a panel.  The goal is
to have the tabNavigator show if the screen resolution is 800X600 and
the panel to show for resolutions above 800X600.  I've tried several
different ways to do this, but none have been successful.  I was
wondering if anyone else had tried to do this dynamically.

Thanks,
Tim Hoff

If you are using cellRenderers (like a text control), I beleive that
you can not set the width of the text field and the column should
adjust.  As an alternative, you can set the variableRowHeight
property of the grid to true.  This will produce multi-line rows if
the cell contents are larger than the set width of the column.

I already tried that. Including trying to assign the property in AS
code instead of MXML. In either case, I get a flex compiler error
saying "Unrecognized combobox property - dropdownFactory". I am
using Flex 2.0. Beta 2.

Hello, i rember a while ago i was at a seminar  and Simon of(Flexcf.com)
had a cool workspace where he had the flex sdk running in eclipse and
compiling using ANT. I want to know if anyone knows how to do that and
it will be really cool  if simon himself explains how he did that if he
has time and reads this email.

All you really need to have to do this is a basic understanding of how ant
works.

For that I recommend the book Java Development with Ant


Or just find some basic ant tutorials on the web

I need to change the selectedIndex of a combox based of a string value.

Example:

Combobox has
"not selected --"
"Arial"
"Georgia"
"Impact"
"Tahoma"
"Times New Roman"
"Verdana"
"Webdings"
"Windings"

I want to be able to change the selectedIndex by that value say if I
have "Impact" it would changed it to Impact.


Thanks
Bill

I've been working on a web application that is free to subscribe to
and use, that would allow people to post and comment on Flex Components.

The site is loosely modelled off SourceForge in functionality, and
will allow the following features:

Create a project
Add files (mark releases)
Add news / messages
Have many developers for one Project/ Component
Searchable listing
and more...

There are some basic details on my little blog:
http://graham.weldon.ath.cx/blog/?p=8
There will also be a Wiki for this appearing this week.

Is anyone interested in seeing this up? With support and suggestions,
I can put more effort in and get the basic site running sooner, rather
than later.

I know personally I would love a central database of flex
components that allows people to freely post components for download.
I am interested to see who would use this.

Let me know

Graham Weldon

Hi Rick,

Thanks for your response, a lot of that I knew already, but its great
to post that information for the other readers too!

Here is the PHP file that I use for the Flex Weather application. I
felt that this may be of use to someone:

--------------------------------------------------------------------
<?
$url = trim($_REQUEST['url']);
$urlString = $url . '?';
$paramCount = 0;

foreach ($_REQUEST as $key => $value)
{
     if (strlen($key) > 6 && substr($key, 0, 6) == 'param_')
     {
         if ($paramCount != 0)
             $urlString .= '&';
         $urlString .= substr($key, 6, strlen($key)) . '=' . $value;
         ++$paramCount;
     }
}

header('Content-type: text/xml');

$handle = fopen($urlString, 'r');
if (!$handle)
     die('<error>Could not open specified URL</error>');

while (!feof($handle))
     $result .= fread($handle, 8192);

die($result);

?>
--------------------------------------------------------------------

Basically, in your HTTPService, you now specify the address to go to
as the <url> parameter, and all parameters for that url are prepended
with the "param_" string:

<mx:HTTPService
     id="myProxiedService"
     url="proxy.php">
     <mx:request>
         <url>{myDataGrid.selectedItem.Address}</url>
         <param_name>{nameInput.text}</param_name>
         <param_age>{ageInput.text}</param_age>
         <param_secret>{mySecretVar}1234</param_secret>
     </mx:request>
</mx:HTTPService>

This allows you to proxy any URL, with any set of parameters.

I have JSP and ASP(VB) versions of this also if people want. Let me know.

I would use it and would be willing to help implement it or host it if
necessary.

I could definitely contribute to it.

Can ya point out where in the Framework that xField and yField get
used by the BarSeries? Not seeing it in BarSeries, Series or
ChartItem....

Here's what I've got so far:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute" xmlns:custom="*">
	 <mx:Script>
		 <![CDATA[
			 [Bindable]
			 private var Jobs:Array = [{Task:"Number 1",Time:35,Depends:-1},
										 {Task:"Number 2",Time:30,Depends:0},
										 {Task:"Number 3",Time:35,Depends:1}];
		 ]]>
	 </mx:Script>

	 <mx:BarChart id="bar" height="100%" width="100%" dataProvider="{Jobs}">
		 <mx:verticalAxis>
			 <mx:CategoryAxis dataProvider="{Jobs}" categoryField="Task"/>
		 </mx:verticalAxis>
		 <mx:series>
			 <mx:Array>
				 <custom:GanttSeries yField="Task" displayName="Task"
durationValue="Time" dependentItem="Depends"/>
			 </mx:Array>
		 </mx:series>
	 </mx:BarChart>
</mx:Application>

Custom series:
package
{
	 import mx.charts.series.BarSeries;
	 public class GanttSeries extends BarSeries
	 {
		 private var _durationValue:String = null;
		 private var _dependentItem:String = null;

		 public function get durationValue():String {
			 return _durationValue;
		 }

		 public function set durationValue(value:String):void {
			 _durationValue = value;
		 }
		 public function get dependentItem():String {
			 return _dependentItem;
		 }

		 public function set dependentItem(value:String):void {
			 _dependentItem = value;
		 }

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


		 }
	 }
}

You'll need to loop over the dataProvider and do a comparison.

Has anyone done a tree grid with columns. What I am really looking for
is a datagrid where the first column had a tree structure that would
allow the showing and hiding of rows.

 have sort of hit a brick wall with Flex I am trying to self teach myself with a book which is fine except I think I could learn a lot more. I believe Flex to be very useful I just want to make sure I can get everything out of it so I can help others. I live in Atlanta Georgia if there are any Seminars on the subject of Flex near me let me know, also I do not mind flying out to go to one if there are any. Also if there are any near Hartford Connecticut let me know

Yes, please use the wishlist to suggest this as a feature for a future
release. I'm afraid that we're too far along on Flex 2.0 to be able to
consider it for this release.

It was interesting to hear your perspective on this issue. My own
experience coding in AS2 and AS3 has been quite different; using AS3 in
a non-dynamic way has significantly increased the productivity of
developers on the Flex framework team as well as the performance of the
framework classes.

To give an example, the project I am currently working on is using a
Ruby on Rails backend and a Flex frontend.  The backend code is by far
the easier of the two to work on, refactoring is straight forward and
the code is simpler to read.  This is due mainly to Ruby's dynamic
nature.

This is an argument that I've heard before but it doesn't match my
experience.  In my five years of programming with dynamic languages,
type mismatch errors rarely occur.  Perhaps they do occur frequently
with novice programmers, and for them a hand holding language may be
more appropriate.

AS3 seems to be in an awkward position of having javascript (dynamic)
roots, while adding compile time checking to function calls and property
accesses.  The result is satisfactory for neither the dynamic or static
typing camps.

Dynamic programmers have to add type qualifiers everywhere, while static
programmers don't always have the compile time type checking safety net.
Using Objects as hashtables and e4x are both dynamic without any static
type checking, and have the "fail silently" error you mentioned above.

The way dynamic languages generally handle the typo problem is to log a
warning in debug mode when an undefined property is read.  Flash 8.5
doesn't do this, and it might be a nice feature to have.

We've drifted a little from the original question - which was how to
dynamically define getters and setters.  I notice that Mozilla's
implementation of javascript allows this.  Would a feature request for
this be worthwhile for me to make?  The reasoning for this request is
for fuller support for dynamic programming in an already dynamic
language.  It's a wishlist, not required.

Dion.
