[flexcoders] Charting: Drilling down into a legend label

[Brad Bueche]

I was just going through an old Flex 2 charting app I did.  And one of the
things I, and my prospective users, wanted to do was to drill down into a
legend label.  (I got drill-down in the charts workingthanks to
quietlyscheming   --- that stuff was not documented anywhere then!)

I'm thinking of resurrecting that... Even though it was my first flex
application it still looks and operates better than anything I have done in
php, html, javscript, or C# asp.net since!!  Now, seeing it again,  I don't
know why I every let it die.  It was a skunk works project. You know,
outside the work your supposed to be doing!  (Then you have to take the time
to sell it around on the quietbut I got busy)

So, anyway,  CAN you drill down into a legend item in FB3 or FB4?

Re: [flexcoders] subversion ? where do i start

[Brad Bueche]

Just go to your software updates and install Subversive.

I've never checked out from a public server but I would guess that its not
much different than a private server.

If you want to use SVN locally, on windows, the easiest solution BY FAR is
to install VisualSVN and get the TortoiseSVN client.  Create your
repository.  Use tortoiseSVN to check them in.  Use subversive to check them
out into FB.   Takes about 10 minutes to hook FB up to a local SVN server,
check out your code,  and do a build.  IOW, you can go from nothing to a
working SVN setup with FB in about 10 minutes (ok 30 if you have never
touched any of this sort of thing before!)

Re: [flexcoders] AIR sql parameters - can I use an array ?

[Brad Bueche]

We just had to solve this very problem this week in asp.net c#.

[with the ack that there are multiple ways to solve most problems]

The way we solved it is to understand that what the db needs is this:

IN (:parameter1, :parameter2, :paramater3, [..])

So you take your input string, split it, put it in a list/array, create some
dynamic variable names  "fieldname + counter".

Do a for each word in list type loop:

fieldname + counter = "'" + word + "'"  //put the single quotes around your
string
sql_string = sql_string +  ":" + fieldname1

Then build the actual sql statement as seen above.  Your single quotes need
to be in the parameter.

You'll need to do slightly different processing for numbers in that they
will not need the single quotes around them.

Sorry, thinking in C# at the moment,

If you need to see how to do dynamic variable names in flex, look here:

[flexcoders] So might as well move everything to FB4 now?

[Brad Bueche]

I'm just developing personal hobby type stuff at this point.   No paying
customers or production work (at least until what I'm working on is far
enough along to demo).

So, I'm thinking, let me know if any of y'all disagree, that there is no
reason that I should not make the jump to FB 4 and just leave Flex 3 behind
for good.

I'm just feeling a little dismayed in that there are still a bunch of Flex 3
books that I was planning to read and now it looks like there are some
fundamental shifts in the flex/flash builder approach to things.  But such
is the price of progress I guess.  For the transition comfort zone, can I
develop in FB4 as if it were Flex Builder 3 and then add specific FB4 things
as I learn them?  I guess that would have to work, right?  (Otherwise, it
would break Flex Builder 3 projects).

Can I run 2 versions of eclipse on the same machine (full Flex 3, and full
FB 4) both with their own java and subversive plugins?

And, its also my understanding that I lose NOTHING by using the plugin (into
an existing eclipse) vs the full install, correct?

Will the FB4 plugin work just fine with a Ganymede 3.4 JEE Birt package?
How about 3.4.1?

[flexcoders] (SOT) Opportunity for FB ? (Hey! Adobe !)

[Brad Bueche]

I've been reading up on Bugzilla and it is frequently mentioned that its UI
is not the most intuitive or easy to use in the world.

Well if one needs an improved UI experience,  is not FB the answer!?  Well
really, the SDK in this case.  Although, I guess, anything you do in FB,
outside of the data visualization, can be updated in the SDK, right?

Is this a good opportunity for Adobe to greatly improve an open source tool
with their open source solution?  To me,  it seems like there is significant
opportunity to show off many of the features of 4.x. in a highly targeted
market.

Anyway, just a thought, maybe I'm way off base.  (Then again, I'm always
late to the party with the flexcoders group,  so maybe somebody is already
working on it).   However, if you do decide to do it, Adobe, see if you can
add some built in integration with Subversion (in keeping with being a major
contributor to the open source community).

Re: [flexcoders] Subversive Client install on full FB3

Sam,

Thanks. Good call, I had forgotten about that method. I got the proxy but
,alas, I think its my laptop firewall config that is killing it here and I
cant change that (well I probably good after lots of digging but then they
could just push out a a new config). Security is pretty tight here.

So my big issue with the subversive client is that I cant get the SVN
connectors installed.  I can get the main package installed but when I
download the connectors package it keeps giving me some sort of error to the
effect that it cant find the archive in the directory that I'm pointing
too.  Even when the exact same series of steps works correctly for the main
package.

sorry for the OT thread,

Re: [flexcoders] Re: Dynamically Naming Objects

[Brad Bueche]

Ok, thanks for the underscore there, Tracy.  Sounds like exactly what I
need.  Basically, at a simple level I'm extending that searchcoders search
interface to a full adhoc query front end.  So the plus minus buttons will
add a row that will have combo-boxes with the data providers --both static
and from a db -- and text entry boxes.  So each row will actually be a
series of sub-  components.   So I guess I could turn the row into a master
component and stick it in the Repeater.  I'll have to look into all these
goodies that the Repeater provides.

thanks again!

Re: [flexcoders] Dynamically Naming Objects

Thanks! Gordon, that worked.  Also thanks for giving the two different
approaches.  I can probably get away with just using the arraybut I was
obsessing about that naming thing so you're giving me both approaches
allowed me to stop obsessing sooner! ;)

[flexcoders] Subversive Client install on full FB3

[Brad Bueche]

Sorry to ask this here but I have searched everywhere over a period of
months and I cant find an answer.

If I install flex builder 3 (full install) at home, and bring it up, I can
connect to the cfeclipse updater and subversive updater in a hearbeat.

However, I need to really use subversive and fb at work not at home.  And I
can not figure out how to get the fb3 eclipse to connect to ANY update
site.  I have to keep installing everything manually.  Well the manual
install for subversive does not seem to work because they wont -- for
license reasons -- put the SVN connectors in the main build and I cant get
the manual install of those to work.

I'm getting to the point where I really, really, need version control and
this is really beginning to slow me down.

Every time I try to do a software update eclipse either gives me the this:

Error Parsing Stream [Premature end of file]

We do use a proxy at work.  I have put the the proxy server config into the
Eclipse->General-Network preferences but this does not seem to work.  I
notice that Eclipse has a setting for port but we dont specifically use port
in our proxy setting.  Additionally, in IE the proxy says "Use AUTOMATIC
Configuration script" whereas Eclipse's set up just says "Manual Proxy
Configuration".

What am I missing here?

[flexcoders] Dynamically Naming Objects

[Brad Bueche]

I have a button that creates new combo boxes with dataproviders.   I can
hard code things and create combo-boxes as much as I want but thats a little
silly.  I need to dynamically create new combo boxes and then reference them
for hooking up the data providers and getting results etc.

I have figured out how to create dynamic variable names.  For instance:

this["cbx" + counter].x = xValue;
this["cbx" +
counter].addEventListener(FlexEvent.CREATION_COMPLETE,createRemoteObject);
this["cbx" + counter].labelField = "Label";
addChild(this["cbx" + counter]);

The problem is that I cant figure out how to dynamically create a new
ComboBox.  This is as far as I can get (and its wrong)

this["cbx" + counter]:ComboBox = new ComboBox();

Re: [flexcoders] Application Idea

[Brad Bueche]

Create a Family Tree.

I mean the visual for the tree.

Branches Nodes Leaves would be either text (Mother/Father, or Family Name)
OR
Branches Nodes Leaves would be thumb nail images.

Mouse/over or hover over a branch, node, tree would bring up a little window
with more info about that particular family (couple).  Hover window could
have children names as links at the bottom of it. Clicking them would take
you to the children.

Clicking in the main part of the hover window would take you to a page of
info about that family.

===
Create a calculator that keeps a running tab on a visual, realistic roll of
paper.  Allow user to grab components on the paper and re-arrange them.  Be
able to still calculate what they have re-arranged on the paper.  Allow them
to save the work on a piece of paper. Figure out what the most atomic
components (building blocks) are.  You'll need to be able to do this in
order to recognize the new statements that are created on the paper.

=
Create an sql interface similar to search coders but enable this to also
create real sql in a text space. Allow them to drag elements around and
re-arrange them.  Then paramertize what they have submitted and submit it to
the database.  The trick is dont let them build in the text area.  Let them
build through a menu'ing system that prohibits nefarious sql.  Why both?
Its very hard to do complex sql with a menu'ing system only.

go full screen and you wont have to scroll around.   I always just click
full screen as a matter of habit so I was not aware of  the issue and didnt
think to point it out. sorry!

Re: [flexcoders] CakePHP+CakeAMFPHP vs WebORB dialema

[Brad Bueche]

If you have SLA's in terms of maintenance and production response with your
customers you may want to partner with the party that can also offer that
contractural level of service to you. (My experience with the webOrb team is
that they are very responsive).  With that said you may also want to look at
Zend before you make a final decision.

[flexcoders] StageAlign and StageScaleMode

[Brad Bueche]

Why do I have to use this (below)  to ensure that my web browser layout is
perfectly synced with my stage?  I would think that my browser window IS the
"stage".   Why is this not true?  What am I failing to understand and where
can I read more to understand whats going on here.

stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;

thanks for your time!

[flexcoders] Solution: Port of (VERY Simple) Flash Animation Example to Flex ActionScript Project

[Brad Bueche]

Yahooo! (Yes, I might be a redneck).  With the help flex coders (i.e.
"y'all").  I was able to port a Flash ActionScript Project to a Flex
ActionScript project.  (Well, Joey Lott's ActionScript video class on
Lynda.com helped a lot too.  I highly recomend lynda.com for beginners -
like me).  The video mentioned that ENTER_FRAME does operate in Flex at a
default of 12fps.  (Where do you change that?).  So I did not have to resort
to Timer.

All of this is an effort to work through the book "Object Oriented
ActionScript 3.0" in Flex instead of Flash.  This is one of the first
examples in the book.   (Only the first few examples deal with animation,
but it was bothering me that I had to download and work with the Flash ide
simply because I wanted to learn advanced actionscript).  I *highly*
recomend the book. I actualy understand 4 patterns now! Now, I just have to
implement them in flex.

The book uses symbol's as MovieClip but I'm using my BasicShapes (extending
Sprite).  Yes, its probably stupidly simple but it has taken me a long time
to figure it out.  So I'm posting it in case somebody else needs something
like this.

Here is the main actionscript class:

-
package{
import flash.display.MovieClip;
import flash.display.Sprite;
import com.bueche.flex.graphics.BasicShapes;
import com.bueche.flex.graphics.Mover;

public class MoveShapes extends Sprite{

public function MoveShapes (){
   var testItem:BasicShapes = new BasicShapes();
   var testItemMover:Mover = new Mover(testItem, 2, 3);
   addChild(testItem);
   testItemMover.startMoving();
}

}//end of Class
}// end of Package

-end of main class

Here is the BasicShapes class:
-
package com.bueche.flex.graphics
{
import flash.display.DisplayObject;
import flash.display.Graphics;
import flash.display.JointStyle;
import flash.display.LineScaleMode;
import flash.display.Shape;
import flash.display.Sprite;

public class BasicShapes extends Sprite {
private var size:uint   = 80;
private var bgColor:uint   = 0xFFCC00;
private var borderColor:uint  = 0x66;
private var borderSize:uint   = 0;
private var cornerRadius:uint = 9;
private var gutter:uint   = 5;

public function BasicShapes() {
doDrawCircle();
doDrawRoundRect();
doDrawRect();
refreshLayout();
}

private function refreshLayout():void {
var ln:uint = numChildren;
var child:DisplayObject;
var lastChild:DisplayObject = getChildAt(0);
lastChild.x = gutter;
lastChild.y = gutter;
for (var i:uint = 1; i < ln; i++) {
child = getChildAt(i);
child.x = gutter + lastChild.x + lastChild.width;
child.y = gutter;
lastChild = child;
}
}

private function doDrawCircle():void {
var child:Shape = new Shape();
var halfSize:uint = Math.round(size/2);
child.graphics.beginFill(bgColor);
child.graphics.lineStyle(borderSize, borderColor);
child.graphics.drawCircle(halfSize, halfSize, halfSize);
child.graphics.endFill();
addChild(child);
}

private function doDrawRoundRect():void {
var child:Shape = new Shape();
child.graphics.beginFill(bgColor);
child.graphics.lineStyle(borderSize, borderColor);
child.graphics.drawRoundRect(0, 0, size, size, cornerRadius);
child.graphics.endFill();
addChild(child);
}

private function doDrawRect():void {
var child:Shape = new Shape();
child.graphics.beginFill(bgColor);
child.graphics.lineStyle(borderSize, borderColor);
child.graphics.drawRect(0, 0, size, size);
child.graphics.endFill();
addChild(child);
}
}//end class
}//end of package

-end of BasicShapes class

Here is the mover class:

package com.bueche.flex.graphics
{
import flash.display.MovieClip;
import flash.events.Event;
import com.bueche.flex.graphics.BasicShapes;

public class Mover extends MovieClip {

public var targetShape:BasicShapes;
public var xVel:Number;
public var yVel:Number;

public function Mover(targetShape:BasicShapes, xVel:Number,
yVel:Number) {
this.targetShape = targetShape;
this.xVel = xVel;
this.yVel = yVel;
}

public function updatePosition(evtObj:Event):void {
this.targetShape.x += this.xVel;
this.targetShape.y += this.yVel;
}

public function startMoving():void{
this.targetShape.addEve

Re: [flexcoders] ActionScript package/class wont produce output (or error)

[Brad Bueche]

Thanks! You made my saturday night! (Yea, I'm THAT boring).

If the class had not had all those addChilds in it I would have normally
thought to do this.  What are all those  addChild's in the class adding TO
then?  Its the same stage, same display list  ???

Re: [flexcoders] What's your favorite Tip/Trick ?

[Brad Bueche]

You might be interested in following the development of this:

http://www.sapphiresteel.com/Download-Amethyst-Adobe-Flex-IDE

They are enabling the ability to develop flex within the visual studio IDE.

Also, a good adobe tv show to wach on thiswell I cant find it
now it was some guy from max doing a presentation on tips and tricks for the
ide.where I learned that the Flex ide keeps many many (dont know
what the limit is) versions of each file for you (just right click the
file and, choose Team, and then Local History).  Didnt get to wach the rest
of it and now I cant find it (after searching through all 18 pages).

But there is a ton of good stuff on there.

[flexcoders] ActionScript package/class wont produce output (or error)

[Brad Bueche]

I'll probably get this working by just changing things until it runs,
however, I'd like to really understand what is going wrong. ;)

My packaged class is below (at the bottom).  IF I  run it as the only file
in an actionscript project (in the Flex 3 ide). It works and draws 3 shapes
onto the screen.

However, if I try to call it from the default application class like this
(immediately below) I get nothing on the screen and I dont get any errors (I
didnt know wether I was supposed to use MovieClip or Sprite either).

Not sure how tied you are to mapquest but yahoo has an AS3 API to their

[flexcoders] Suggestion to enable adobe TV to be more effective

[Brad Bueche]

I may just be showing my ignorance here (and, if so, please point that out
to me).

1)  Enable the video's to be downloaded.

2) Enable them to be downloaded as podcasts.

I would imagine that a great many people do not have the
ability/infrastructure/funds to be connected all the time.

[Yes, this is not a code question but its the only place I know for sure
that high level adobe peeps hang out]

And the video's are great!

Re: [flexcoders] Vidoe Tutorials Needed

[Brad Bueche]

You can also try lynda.com.  They have excellent video's.  They even have
Joey Lott teaching ActionScript 3.0 (and not framework specific at that!).
 They have about 50 hours of flex traning alone. They also have Flash CS4
(CS3 and older) training. Dreamweaver training.  ColdFusion 8 training. etc.
 Very good and high quality video.
$25 a month though.   However, I was  watching the free ones last night
(approx first 5 lessons of each course are free) and they are  very good.
lynda.com covers  all the Adobe CS software (even older versions)

designprovideo's also has some adobe cs4 training but not nearly as  much as
 lynda.com does.

Re: [flexcoders] Re: Flex Component Kit still needed for CS4?

[Brad Bueche]

Nate,

Exactly.  This is my question.  The  adobe website seems to
be inadvertently linking a  CS4 website to a CS3 page because they never
specifically state "Yes, we are sending you from a  CS4 page to a CS3 page,
but you are still required to install this on CS4 as well if you want to use
this particular package as it does not ship as part of CS4".

[flexcoders] question for flex coders

[brad]

Why does my dateformater NOT work in my grid (below) if 
I specify the resultformat as E4X?  Thats the only difference 
I can see in the grids below. 

Grids 1 and 2 are not e4X and yet they display the date as processed by
the dateformatter.
 
Grids 3 and 4 are e4x and the field is just blank for them.
 
Hopefully I'm not being bone-headed!
 
thanks in advance,
brad
 
Relevant Code Snippets follows
 

 
**

In case anybody ever stumbles on something similar, I figured out the 
problem.  I needed to match the overridden function more closely.  
Here was my final code that worked correctly:

override protected function drawHighlightIndicator(indicator:Sprite, 
x:Number, y:Number, width:Number, height:Number, color:uint, 
itemRenderer:IListItemRenderer):void
{   
var g:Graphics = Sprite(indicator).graphics;
g.clear();
g.beginFill(color);
g.drawRoundRect(0,0,width-10,height-16,20,20);
g.endFill();

indicator.x = x;
indicator.y = y+8;
}

[flexcoders] Locale Resource Problem Compiling Automation with Maven

[Brad Keck]

 I am trying to compile my code with automation libraries so that it
can be tested with silk.  Currently, I am able to do this without 
trouble in Flex Builder using this command line argument: 
-include-libraries "...\automation.swc" "...\automation_agent.swc" 
"...\FlexTechDomain.swc"  (... represents the full path on my local
machine)   However, we have continuous integration using a maven build
so I am  trying to get it to build that way.  When I do so, however, I
am  getting these error messages:  [ERROR] Unable to resolve resource

[flexcoders] Manually Downloading Flex Updates

[Brad Bueche]

I cant seem to get the right search string to find the answer to this in
the archives.
 
My Help->Software Updates always just goes out to lunch.  This probably
because of local firewall settings (which I cant change) and/or network
firewall settings.  Is there web page that describes how to get the
update manually?  I had to get CFEclipse manually. 
 
Right now my feature details says I have:
 
Flex Builder Core3.0.205647
Flex Builder Standalone:3.0.205647
 
I'm assuming this is not the most current rev.

[flexcoders] Need a Flex 3, using local cfc server, tutorial

[Brad Bueche]

Ok, finally getting back into flex (TO STAY) after almost a year.  I
even purchased Flex 3 professional with my own money!  And I'm going to
make another attempt to get flex apps into my area of the company.
 
I tried the wizard but wizards are a Catch-22:
 
If you need the wizard to create your code, you'll get something that is
essentially nothing more than a demo and you wont understand how it did
what it did or where to go from there.  If you understand what the
wizard does and it could actually use a wizard to speed things up, you
dont need it because you'd rather do it your own way.  (They really seem
to only be useful for impressing people who dont actually code).
 
The tutorials that I have found so far assume you are using a J2EE
implementation..or they are for Flex 2.  So I need one for Flex 3
that walks through using the local cf server.  I have cf hooked up to
the db's (data sources work).  And the wizard demo app works.  However,
I dont need what the wizard does and I dont understand how its laying
out all the files.  I need an explanation of that so that.  If anybody
knows of some good walk throughs or tutorials on this pleas let me know.

[flexcoders] indexing of Flex web site in Google

Re: [flexcoders] Re: Do you use a Mac?

[Brad O'Hearne]

As I recall, the "PC" term was originally associated with early IBM  
model computers, was it not? I believe as Windows embraced the IBM PC  
architecture, while the Mac OS did not, the PC generally became  
synonymous with Windows (the dominant OS on the IBM PC platform).


It is a fairly pedantic argument anyway, because if anyone wants to  
get purist about terms, "personal computer" is actually an improper  
reference as well, as there is nothing inherently "personal" about a  
computer anymore, given that computers not only host multiple  
simultaneous logins, both local and remote; but also that a computer  
is commonly shared by numerous different people in homes, in  
businesses, as point of sale units, Internet cafes, etc.


I'm going to go try to retrieve the lost minutes of my life now... :-D

Re: [flexcoders] Setting the font weight / thickness of a LinkBar

[Brad O'Hearne]

Perhaps I asked this question wrong -- does anyone know how to make  
the font weight / thickness of a Link Bar change? Within Flex Builder,  
I have the font of the Linkbar set exactly the same as other text  
objects, but the text is noticeably different -- the LinkBar text  
looks shorter and thicker, and I cannot seem to alter this via CSS.  
Does anyone know how to affect this?


Thanks,

[flexcoders] Override drawHighlightIndicator

[Brad Keck]

I am having a weird problem.  I have created a custom list class in 
order to customize the highlight behavior of the list.  Everything 
seems to be working great EXCEPT when I use the *mouse wheel* to 
scroll, my highlighting gets off.  (The wrong item in the list is 
highlighted as I roll over items.)

Any ideas of what might be going on here?




Here is my code:

override protected function drawHighlightIndicator(indicator:Sprite, 
x:Number, y:Number, width:Number, height:Number, color:uint, 
itemRenderer:IListItemRenderer):void
{
var g:Graphics = Sprite(indicator).graphics;
g.clear();
g.beginFill(color);
g.drawRoundRect(x,y+8,width-10,height-16,20,20);
g.endFill();
}


And for comparison, here is the code in listBase.as:

protected function drawHighlightIndicator(indicator:Sprite, x:Number, 
y:Number, width:Number, height:Number, 
color:uint, itemRenderer:IListItemRenderer):void
{
var g:Graphics = Sprite(indicator).graphics;
g.clear();
g.beginFill(color);
g.drawRect(0, 0, width, height);
g.endFill();

indicator.x = x;  (I have tried adding these lines in,
indicator.y = y;   but they just screw things up bad.)

[flexcoders] Httpstatus from httpservice?

[Brad Keck]

I am using an httpservice to retrieve an XML document.  I want to find 
out the httpstatus I am receiving on the call to handle errors. 
(Specifically, I'm looking for a 30x code to handle a redirect if the 
session has timed out.)  

It does not seem that the either the fault or result events from 
httpservice.send() contain this information.  I also see that there is 
an HTTPStatusEvent in flex, but it does not appear that httpservices 
trigger this event.  

Can anyone help?  Thank you.

[flexcoders] Deep Linking Problems

[Brad Keck]

Hello,

I am just having a slew of problems with Deep Linking in Flex 3.0.  
The documentation makes it seem so simple, but nothing seems to work 
as expected.  I've experienced:

-The example code from the documentation not working
-Vastly different behavior between browsers
-URLs failing to update with setFragment()
-The back button not changing the URL after a setFragment()
-The forward button not being enabled after a successful back button
-A myriad of other inconsistencies

So, basically, I'm just wondering if anybody else has had good 
success with deep linking.  Is it simply a buggy feature of Flex at 
this point, or am I really an inept as I seem?  :)  Are there any 
particular "gotchas" about making this whole thing work that I may be 
missing?  (I have read already that things tend to work better when 
actually deployed on a server, as opposed to run from the IDE.  All 
of my problems are on a deployed app.)

Thank you very much.

Since the filtering and sorting affects the iterator over the
ArrayCollection, I believe you could create a new ArrayCollection,
then do a "for each" over your current ArrayCollection, adding those
items to your new AC. The result will be a new AC with references to
the currently filtered and sorted items in ordered. Then you can apply
your sorting/filtering to the new AC so it will affect any future
iterations after adding items.

[flexcoders] Tree in Combo Box example code (using HTTPService and XML)

This is really from one struggling newbie to other struggling newbies. 
 
This code is really just code from here:
http://kmossman.blogspot.com/2007/03/blog-post.html
 
that I adjusted to read from a xml file via HTTPService, using the xml
file that was used in this code:
 
http://blog.flexexamples.com/2007/11/29/opening-nodes-in-a-flex-tree-con
trol-using-the-expanditem-method/
 
All the code and xml required to do a simple tree in a combo box example
(pulling in external xml for the tree) is below.  Just take the xml and
pasted it  into a file named mlb.xml.  Past the main code into your main
mxml file and past the component code into a component named
TreeComboBox.mxml and you're done.

Thanks for the feedback Peter and Alex!
 
I have also found these two possible solutions:
 
http://cyberdust.wordpress.com/2007/02/23/introducing-selecttree-the-dro
p-down-tree-control/#comment-4946
 
However, this guy did part of it with cf and I'm getting an 1180 Error
"Call to possibly undefined method SubjectGateway".  I've asked if he
can give a flex only example.  As I'm a newbie, I'm much more into
re-use at this stage than writing the specifics myself (I"m learning as
fast as I can!). 
 
There is also this solution:
 
http://kmossman.blogspot.com/2007/03/blog-post.html
 
I'm still taking a look at this one.
 
Its a good sign though that you can think of something you might like in
flex, google it, and get multiple samples.  This is what enabled me to
learn php so fast.  I found them both by just typing "dropDownFactory =
Tree" into Google.

Is there anyway to get the tree view INTO the combo box?



I really like the idea of having a hierarchical menu that looks exactly
like the tree in this example.  I just want it to drop down and be a
menu like the combo box.  I detest the windows file manager interface
(because of its inefficient use of screen real-estate) and I dont like
cascading menu's because I get really annoyed having to slow down and
use my mouse in slow motion just so I can get to the sub-menu I want.



I think the drop down tree hiearchy within a combobox solves both of
these problems. 1).  Its a great use of screen real-estate  --- if you
are not using it it takes up practically no room and 2) the hierarchy is
persistent and I dont have to be a jedi master with my mouseand I
dont have to move %80 down and to the right to get the menu I want.



So would it be possible to do a tree in a combo box?  Or, if thats
impossible, I guess I can just put the tree on a application bar and use
it like a menu?

I think you should be able to use a .string function and just (one way
of doing it) match the positions (in the string) of the time (since it
will always be the same -- give your formatting).
 
I pull data from an oracle database.  I do it via php though so I have
php do the string parsing before it puts it into an xml file. You also
have the option of changing the formatting on your database query so
that it only returns the time (and not the date) (i.e. hh:mm:ss)

Subject: [flexcoders] Flex Charting with MySQL datetime field



Hello Everyone,

I have been digging into the flex charting components with nice
success. Currently I have extracted a large dataset from a mysql
database and would like to plot a line graph with the y-axis being a
value and the x-axis being a time. 

Can anyone point me in the right direction to accomplish this, the
time field is returned as an mysql datetime field (ie MM-DD-
hh:mm:ss) and I would like to have the data displayed only as the time
since all of the dates are the same

Thanks in advance for any direction on this

Don

There's a good little book called "Flash Hacks" published by O'Reilly
that has some maths intros in it for motion, effects and perspective
etc.

If you really want the maths then try "Numerical Recipes for C" - it's
not too hard to make the mental translation to AS3, after all the
maths is universal.

Failing that, grab a latte and a maths text book from off your shelf
and go and sit in the park for an afternoon.

[flexcoders] OO Patterns and Design Analysis Books based on Flex/AS3?

[Brad Bueche]

Do any exist (based on flex2+ and AS3)?
 
I have the O'reilly head start stuff but its based on Java.  I'd much
rather have these books based on Flex/ActionScript.  Also, Adobe, having
books like this of course ushers in new converts to your market place.
So I get the knowledge I want in the language I want and you get more
money for your stock holders. Sounds like a win-win situation.  Oreilly
already knows how to do these books, so go with them.   In fact, to make
it easy, just take the existing books and convert them to
Flex/ActionScript.
 
So let it be written, so let it be done.
 
Let me know when they're on amazon and I'll pre-order!
 

Ok, maybe throw in CF there because large scale OO design is going to
require backend.  Incidentally, wouldnt it be better if Flex/Flash/CF
were all one language and 1 IDE.  Flex is saving me from having to learn
javascript, advanced html, DOM, and ajax.  Now I'm going to have to
learn CF syntax though. I think, adobe, that you are pretty darn close
to critical mass here (with flex as the spearhead -- to mix metaphors) I
think you have the chance to grab major market share from MS and
Sun.but it comes down to the mix and your timing. At any rate, I
think your front door welcome mat should say "FLEX" and that an open
sourced AS3/MXML engine should permeate your product lines. (One Land!
One King!) Yea, and name this project "Excalibur"
.

For the XMLList collection, do this:

public var dpCollection:XMLListCollection;



dpList = event.result.month; 

dpCollection = new XMLListCollection(dpList);



One suggestion for flexibility: Keep a reference to the root of the XML.
My advised code below:

private var _xmlResult:XML;

public var _dpCollection:XMLListCollection;  //the leading underscore
just indicates that this is an instance scoped var



public function resultHandler(event:ResultEvent):void 
{ 
_xmlResult = XML(event.result);  //you can
also use the "as" operator

trace(_xmlResult.toXMLString()); //so you
can see exactly what you have

var xlMonths:XMLList = _xmlResult.month;  //this interim var
not required, just for clarity and debugging

_dpCollection = new XMLListCollection(xlMonths); 

linechart.dataProvider = _dpCollection;//this is
find, alternatively mark var [Bindable] and bind linechart dataProvider
to var

}// resultHandler



The "strong typing" is really a separate issue.  The above is fine
unless you have MANY renderers on screen at once.  I'd say do it like
above first, and go to the ArrayCollection of strongly typed objects if
necessary.  



The creation of the ArrayCollection is a manual process.  You will
for-loop over each xml node in the XMLList, create a value object, and
assign the object property values from the xml atribute values (often
the VO takes an xml node and does this itself).  Then you addItem() the
item object to the ArrayCollection.  All this happens in the result
handler.

If you are not going to programatically update an individual data 
provider item, them XMLList will be fine.

However, if you ever want to have a user update a property of an 
item, in some editable cell for example, then you need to wrap the 
XMLList in an XMLListCollection.

This is because when you use the collection API to modify the data, 
events are dispatched to ensure the UI updates to match the data 
update. This is similar to the relationship between Array and 
ArrayCollection.

There is no performance reason not to use a collection. If you do 
not, then Flex wraps your XMLList or Array in a collection itself.

So, there are no reasons not to use a collection, except for one more 
line of code, and several reasons you should.

Performance caveat: It has become clear that accessing data an xml 
node is significantly slower than accessing data in a strongly typed 
object. This can be noticable if you have, say, a large datagrid 
that displays hundreds of cells.

If this is the case with your app, then best practice is to pre-
process the e4x xml into strongly typed objects in an ArrayCollection.

RE: [flexcoders] do you need CS Degree to get a job?

[Brad Bueche]

If its your first job in the field a degree will certainly help.  After
that you had better have some good references and be able to code on the
spot. You also need to be personable in the interview (no small point).
 
I was a political philosophy major.  It was the only degree I could find
that didnt have a math requirement at my school!  (Still had to take 6
hours of statistics .twice).  My first job was as a bill collector!
Didnt like that so I quit, worked construction, and took some night
school classes in programming (cobol, pascal, c)(1988!). Somebody in my
class got me a job at a bank and I've just gone from there.   I've been
through several banks and two startups. One very successful, one not.
I've been through several managerial positions.  I personally dont care
if you have a degree or not.  I care about what you know and (VERY
important) how motivated you are/how much passion you have for what you
do, and how much of a team player you can be. Its absoluteley no fun
working with people who are not doing what they love (this job just
requires too much dedication).  Its also a colossal waste of time and a
huge vulnerability to hire people who can not communicate with others
and/or are elitist (therefore, the team player requirement).  If you
give short answers at an interview and talk to your feet, you wont get
the good jobs.  With all this in mind, a degree is, therefore,
irrelevant to me.  Most of the people I would hire will come through
mutual friends (linkedin is a great source for this).
 
NEVER burn a bridge (5 years down the road, you have no idea who is
going to be the decision maker in something you want/need very, very
badly).  And ALWAYS keep in touch with people you know are good,
motivated and love what they do.  Build your short list of contacts as
you advance through your career.  It WILL be a life saver sooner or
later. (The coolest idea in the world and VC money are useless unless
you can build a good team).
 
Somebody mentioned putting a blog up and posting like hell.  I think
thats is a great idea!  Its much better than a resume.  It shows that
you are motivated, it displays your talent level (code wise), your
organizational ability, your ability to explain difficult concepts, your
ability to communicate in writing, and, it can, show your ability to
deal with annoying people! (And, at deadline, after a 60, 70 hour week,
everybody gets annoying!) A very good idea.

RE: [flexcoders] Prohibiting Old Chart from Displaying while new Chart renders

[Brad Bueche]

Actually,  there was another component in my program doing essentially
the same thing (i.e. allowing users to go up and down from year to
month) and not having the problem.  I realized that for that component I
was only loading the xml once.  In this one that I was recently having
problems with, was grabbing the entire years xml every time they changed
month. I rewrote it to only load at startup and the problem disappeared.
 
Do you know of any tutorials or code samples for usint the progress bar?
I was using show busy but the show busy clock was showing longer than
just waiting for the xml to load.  Is there a way to shut the busy
cursor off or put a timer on it?

Put a progress bar in a model popup window when you call the data

provider routine, and take the model popup down when you finish
processing the result from your data provider.

[flexcoders] Editor commands in code

[Brad Bueche]

In Visual Developer, one can insert markings that allow one to collapse
sections of code (expand, collapse).   Does the Flex 2 IDE have
something like that? I'm getting tired of paging through long sections
of code.  Also does the Flex 2 IDE have the ability to do split screen
views of the same file (like Komodo allows)? This would also help avoid
paging back and forth as I could compare two sections of the same file
to see what is different.

You are not understanding "deferred instantiation" I'd wager the
component that works is the "0" index child of the ViewStack.



The child componets of a ViewStack, or TabNavigator, are not rendererd
(do not exist) until a user navigates to that view.  This is to improve
startup response by not requiring that the entire application be
rendered before the user can interact with it.  So you can't
programatically reference the a child of a ViewStack until it is viewed.



Best practice is to use an event, like show, or creationComplete to
fetch the data into the component, instead of trying to set it from the
"outside".  So have your resultHandler set a Bindable instance variable
with the data, then bind to that in the components.



Search the Archive or google for "deferred instantiation" and
"creationPolicy" for more info.



Tracy

Subject: [flexcoders] Component Visbility in ViewStack



I am trying to assign a value to a component property in my
actionscript.



If the component is NOT in a viewstack, everything works fine.



If the component IS in the viewstack, all I get are null object
reference errors. I also get the warning "unable to bind to property
'month' on class 'XML' (class is not an IEventDispatcher).  The line it
blows up on is "bucketComponent.month_number = "9";



I have another component in the same program IN the viewstack that does
not have this problem. And I'm doing essentially the same thing in the
component that works.  



In the component that does not work I do the following:



[Bindable]

public var month_number:String = '6';   // this is just a default
setting

private var xmlService:HTTPService new HTTPService ();



private function loadXML():void

{ 

   xmlSerivce.url = "http//longurl/generateXM.php"

   xmlService.resultFormat = "e4X"

   xmlService.addEventListener(ResultEvent.RESULT, resultHandler);

   xmlService.send();



}



private function resultHandler(event:ResultEvent):void

{

linechart.dataProvider = event.result.month[month_number].day;

[flexcoders] Thanks Sherif!

[Brad Bueche]

I couldnt find the original message but I was asking a question about
how to move around from component to component.
 
You mentioned viewstack. I had to drastically re-think my approach to
the application ( I'm new to OO).  However, I've re-done things around
view stack and its working a lot better.  Essentially, I wanted to
conceptually do the bread-crumb trail that Ely does on his drill down
chart example at quietlyscheming.com.  I have not gone back to look at
his code to see how he does it but have figured out how to do it with
viewstack.
 
thanks!

RE: [flexcoders] Convert LineSeries to ColumnSeries

[Brad Bueche]

I was mis-interpreting the error message on this.  
 
The problem was that for a line chart click event, the event handler
tries to figure out datapoint was clicked by doing -- among other things
-- 
 
props = ColumnSeries(hitData.element).displayName;
 
Well obviously I need to be using LineSeries(hitData.element).
 
So my question is this:  How do I tell if the object that kicked it off
is a Line chart or a column chart?
 
The other way I was approaching this is to say  "if this event came from
the object with this id"  but I dont know how to do that either.
 
???

[flexcoders] Moving Screen Control back and forth between components

[Brad Bueche]

I'm doing a charting application that allows the user multiple ways to
look at the data (both from a time hierarchy perspective as well as a
line of business organizational perspective).
 
My current problem is that when I drill down from the main (i.e. year
level view) component, say to a month component,  how do I get back the
main component.  I can move around within 1 component (applying
different chart types to the same set of data) using includeinlayout and
visible.
 
In fact, to get to a sublevel component I just turn off the other
components and make that one (includeinlayout and visible).  But now
control has passed to the sub-component and I dont know how to get back.
You cant turn off the component that you are currently in can you?  I
tried states but I find the includelayout and visible a lot more
straightforward to work with.  But I guess I can go back to states if
that is what is required here.
 
thanks

lastResult doesnt work in Actionscript only MXML, you get null if you
use it in actionScript it should be just 
private function initApp():void{

chartXML.send();

chartXML.addEventListener(ResultEvent.RESULT,onResult);

}

Hi,

I have a Tree with the dataProvider being an XMLListCollection. When
looking at the dataProvider with the debugger, all I see is a single
XMLList that contains the complete XML structure - that is all the
nodes and sub-nodes all in one element. I have a routine that will
traverse the tree and find nodes based on parameters I set - and it
will open those nodes. However, I want to be able to jump from found
item to found item, but I can't find a way to set the index to
highlight the item. Is there a way to do this that someone could
explain?

Thanks,

RE: [flexcoders] Re: Currency Validation

[Brad Bueche]

What if you take control of the error yourself and use the
 
invalid tag (or atribute or whatever its called) of the
CurrencyValidator?
 
something like
 
invalid="txtresult.text = 'Enter only currency in this format $##.##' "
 
And use the trigger and triggevent attributes of CurrencyValidator too
so that you control when it gets validated.
 
Default, I think, is that it triggers on valueCommit for a textinput
field.

Var xlcResult:XMLListCollection = new XMLListCollection(xlResult)
 
I dont understand how this is better. I'm not disputing it. I just dont
understand. 
What will this enable me to do that I'm not doing now? (Again, I'm
asking to understand, not to dispute)
 
If you just want to give me a reading list thats fine too.


thanks for your time.

Yes, binding to lastResult is, as you are seeing, hard to debug.  Use a
result handler.

For the immediate problem, add some code to the function that checks
the first parameter for null, and returns a null value of the
appropriate type in that case.

But for a more robust application, you should stop using lastResult.
Direct use of lastResult is really only appropriate for prototyping.
You are much better off using a result handler to process the result,
handling the special cases, and putting the appropriate values into
variables that you then use for the binding.

RE: [flexcoders] Adding Event to Object that doesnt have one

[Brad Bueche]

Ha!  I figured out the xml thing. i.e. why when referencing
01, I had to use a 1.

chartXML.lastResult.month[1].day

Month[1] is an array reference! I figured it out when I wasn't getting
any data for December! :)

You probably knew that but I didn't.  I thought I was directly
referencing/compariing on  the "02" string for month_name. However, I
was referencing the array position for month_name.

Thanks!

My first thought was why the remote end sends back the month, so I guess
you 
have all 12 months on screen at once ?

If, as you say further down, it's an '02'/'2' thing, just change either
the 
Flex or the remote end so it does what you want.

Scott,
 
Thanks that works great!!!  Man what  load off my shoulders now that I

I was doing it in actionscript and in there it needs to be

RE: [flexcoders] Adding Event to Object that doesnt have one

[Brad Bueche]

I can have all 12 months on the screen at once, that will be my year
view.  Or I can do the month[number] thing to refence one month. I'm
tyring to put as much data into a single xml file as I can, and the just
hook the dataprovider up to sub sections of it. E4x's xpath like sytnax
allows me to do this (very nice).

Here is the code for moving through months.  The component simply throws
up an additional menu that lets the user choose from different chart
types (using the same data set).  I have to use the menu until I can
figure out how to enable horizontal access labels to be clicked upon
(allowing me to catch the event and the go to the charts for that
month). After I get v 1 out the door I can probably make the component
even more generic so that it will work for any time period from year
down to hour.

Yes, my first little Flexlet ;)

RE: [flexcoders] Adding Event to Object that doesnt have one

[Brad Bueche]

Unless I am missing something (entirely possible) it looks like Darron
is just pulling the y value for the event while clicking on a datapoint.
I had already figured out how to do this (thanks to a post here).  
 
What I need to do is to be able to click on the actual labels in the
horziontal access and generate an event that allows me too pull up a
detail chart for that time period.  I have some books that have info
about adding events to something that doesnt have it. So I'll research
that and let y'all know. [The newbie problems that I'm bound to run
into!]

RE: [flexcoders] Adding Event to Object that doesnt have one

[Brad Bueche]

Ok, I have, thanks to this group made a LOT of progess here.  This is my
first flex project and I'm trying to get a cool charting site up while
everybody is interested in a cool charting site.  

I think I have figured out the problem.  But, just to give some
background

This is what my HTTPService call looks like:

http://path/createXML.php";
resultFormat="e4x">

Program views month data for 6 groups, provides year views, with month
drilldowns.

A single MONTH component offers line, clustered, stacked, and 100%
charts for the given month.

Data provider for the chart looks like this"

dataProvider="{chartXML.lastResult.month[02].day}"

That would the feb component.  There are 4 charts in here.  I change
charts by changing state. Charts are changed by using a combo box and a
case statement. For each state I use activate to call "chartXML.send()".
Although I'm not sure why I have to do that.  I thought the flash client
cached its data.  (Yes, this is called programming by throwing mud at
the wall and seeing what sticks).

In the component I declare at the top:

[Bindable]
 public var month_number:String = "02";

I use the component like this:



And it turns out that I had everything right but I was putting "02" in
the month.  HOWEVER, this IS what is in the xml. The xml is like this:

02

However, "02" doesn't work.  "2" works.  Does XML ignore zero?

you can use a method to get around that

private function getDp(lastResult:Object, month:String):String
{ return lastResult[month].day;
}

The method will be called when ever one of it parameters is changed

RE: [flexcoders] Re: Adding Event to Object that doesnt have one

[Brad Bueche]

Would it be possible for you to give me a short example of adding the
event in this manner?
 
The only syntax I am familiar with is as follows:
 
columnChart.addEventListner (ChartItemEvent.ITEM_CLICK,myListener);
 
but this, I think, is only for adding events to object that already have
event types defined.
 
thanks for your time!

Well to answer your first question: "How do I add events to an item
that does not have any?" - your object can implement the
IEventDispatcher interface or you can extend EventDispatcher. Either
way is the only way that you are going to get your object to be able
to make use of the Flash Player's event system.

I really can't answer your second question with any authority since I
haven't done much with Flex Charts. I think from what code I did have
to work on, it was pretty much a situation where you retrieve the x,y
coords of the mouse relative to the whole chart. I could be wrong at
various points but I think that is the only way I have seen it done.

[flexcoders] Adding Event to Object that doesnt have one

[Brad Bueche]

I'm new to flex so there may be an obvious way to do this that I am
missing.
 
In my charts, my users want to drill down from the month view to the
days of month view by clicking on the month name (categoryAxis,
categoryfield) for the horizontal axis.
 
However, from what I can see CategoryAxis has no mouse events (or any
other events) associated with it.  So my question is specific but may
have broad application.
 
1.  How do I add events to an item that does not have any?
2.  How do I associate this event with a layout on the screen where the
object seemingly keeps no reference to position?
 
The only thing I can think of is pursuing looking at the fully rendered
chart, figuring out x and y coordinates of the items (from an eyes on
view),  and then making areas of the screen clickable (and able to
generate events).   This does not seem very generic though and seems
heavily dependent up on eyes on the screen (which seems fraught with
peril to me).
 
Suggestions? 
 
Since I'm new to flex, it would really help me if the answer could be
tied specifically to the categoryAxis issue thats stumping me.

RE: [flexcoders] Re: Need IF Logic for Chart Data Provider

[Brad Bueche]

Thanks your reply/time.
 
The issue with the @attribute=="blah"  syntax was that I have month_name
as an element instead of an attribute.
 
Just learned about attributes.  I'm creating the xml myself in php
(which is querying oracle).  So I can put the attribute in there.  It
looks like it gives you much more powerful search capabilities (as well
as more readable code).

I think you just need to change the "" to '' like so:

dataProvider="{chartXML.lastResult.month.(@month_name=='01').day}"

However, you might be better off doing:

dataProvider="{chartXML.lastResult..month.(@month_name=='01').day}"

Here's a good quick reference too: 
http://www.sephirot
<http://www.sephiroth.it/tutorials/flashPHP/E4X/page002.php>

As a disclaimer, I have very little e4x experience but I presume that
it will get you where you need to go.

[Brad Bueche]

Ok, I have Sas Jacobs' book,  "Foundation Flex for Developers: Data
Driven Applications with PHP, ASP.NET, ColdFusion, and LCDS".  She has a
chapter on working with XML using E4X.
 
What works, for me in this case, is this:
 
dataProvider="{chartXML.lastResult.month[0].day}"
 
In fact just to see if it would work I declared 
 
public const JANUARY:int = 0;
 
and then did 
 
dataProvider="{chartXML.lastResult.month[JANUARY].day}"
 
This worked too.
 
  HOWEVER, I have been told that using brackets is too hard to debug.
and that I should use a result handler to wrap the xmllist in an
XMLListCollection instance variable and bind to that. Sas also covers
that.  I'll read up on that and let you know.  OK, read it. I'm using
the  and, as far as I can tell from Sas' book, the
HTTPService tag apparently takes care of creating an XMLListCollection
for you.or maybe it just creats an XMLList.  Can anybody shed some
light on this?
 
I also learned (from the book) that the following should work:
 
dataProvider="{chartXML.lastResult.month.(@month_name=="01").day}"
 
However, it doesnt as I get the following error:
 
Element Type "mx:LineChart" must be followed by either attribute

If you use the square brackets then you don't use the dot so it should
be:

RE: [flexcoders] Re: Need IF Logic for Chart Data Provider

[Brad Bueche]

Abyss,
 
I forgot to mention, that I am using e4x. 
 
I see ted's mention of that "@" syntax not sure what that is. I'll have
play around with it. 
 
Do you know where there is a good practical (cheat sheet) approach (as
opposed to a comp sci approach) to using E4X?
 
I've looked at amfphp but I dont understand any of the examples.  
 
Right now, I think xml via e4x is kind of cool. This is an internal app
on 100Mb connections, and I'm creating all the xml before hand so
performance is not bad.  
 
thanks for your time!
 
brad

[flexcoders] Need IF Logic for Chart Data Provider

[Brad Bueche]

The problem (in short):
I need to be able to hook up my charts to dataproviders where
 equals "January". And only pull that.  I dont need it to
read every month in the hierarchy. Or month_name is January and day_name
is '14'. In order to do this I need to do IF logic with the dataprovider
it seems to me.   My other post occurred because in leiu of being able
to do  "IF month_name='January'.  I have just gone in and changed the
xml so that instead of   [...]  it now says 
 etc. That sort of defeats the data
description aspect of XML (it seems to me).  
 
 
The background (if you are interested):
This problem has to do with me NOT wanting to write 100+ reports to
generate 100+ separate xml files to access.
 
I need to track the metrics of several internal groups over the year via
charting.  I want to drill down into individual months (by day) and --
maybe, days by hour.   I also want to track into the sub groups per
month and per day-in-month for each of these groups as well.
 
The data is network event traffic and doing the queries live will just
not work. Users wont use the slicing and dicing visualization affords if
they have to wait every time the click an item.
 
So, I know I can save myself a lot of reports by putting all the data
into about 10 - 20 reports or so by using the XML as its supposed to be
used (i.e. describing the data).  I need to be able to hook the data
provider to only a sub-node in the xml hierarchy and not have it read
everything at that level. I need it to read only has long as
month_name=January or month_name=January AND day_name='15'.

RE: [flexcoders] Embedding String Variable in dataprovider name

[Brad Bueche]

Maciek,
 
Thanks for the quick reply.
 
That generates the following errors:
 
Syntax error: expecting rightparen before rightbrace. [Generated code
(use -keep to save):
1084: Syntax error: expecting identifier before leftbracket
1084: Syntax error: expecting rightparen before destination
 
I put a right paren before it just to see what would happen.  It got rid
of the errors! but it still didnt work :(
 
I was able to get categoryfield and title to accept the  ="{StringName}"
syntax though.   I even tried to replace the entire  dataprovider entry
with a stringname, like so:
 
dataprovider="{stringName]"
 
but that did not work either. 
 
There is a larger problem that led me down this path.  But I'll open
that in another thread as it would still be really cool to figure if I
could do what we are talking about in this thread.

Date: Fri, 01 Feb 2008 15:40:25 -

Really what I need to be able to do is insert the variable name in this:

dataProvider="{chartXML2.lastResult.month.day}"

I need to replace the "month" with a string variable name (i.e public
var monthName = "January";)

I also need to do the same for the categoryfield as it will not let me
do categoryfield=$String.

In PHP this is incredibly easy to do. You just say blah=$string . In
fact, in PHP you can embed variable names everywhere. Its very
powerful. For instance, in php, for the dataprovider issue above, i'd
just do

dataProvider="{chartXML2.lastResult.$StringName.day}"

and it'd work just fine. Whats the syntax for doing this in Flex?
