[flexcoders] Just getting started with flex builder 3

[richbull99]

Hi all.

I've been working on a site that has some rather large text files.
I think it can be better served in flash.
I kind of like the idea of having an expanding tree doing most of the
work. Where the left side of the page would show basic information,
then the right would show more detailed stuff.

What I need though is a working example of one. To help give me a
start in this area of technology. At least one that shows the basics
of getting it started. As most of the data will be repeated a few times.

I would have loved to tried out the example sent in the welcome
letter, however, I was met with an error right off. Seems somebody
didn't bother to validate the code.

For a reference, my site is http://oldies.1littleworld.com/

Thanks

Re: [flexcoders] Re: DataGridColumn trouble...

[Sefi Ninio]

Exactly what I was thinking...

So, to make sure I get this straight - There is no way to get to the other
DataGridColumns from the DataGridColumn passed to it's labelFunction.

There is no getting around to making the same calculation for multiple
column except for keeping an external map (at least the size of the grid -
which chould be quite big) for the calculations results. This, of course, is
a mess. More so when you need to update the map when the dataProvider
changes...

Ugh... Coding in Flex is a real joy, but every now and then I find myself
banging my head against the wall...

In the code for this article:

Is logic that parses xml and instantiates various UI classes based on
the xml.

[flexcoders] [ANN] Flex-mojos 2.0-alpha4

[Marvin Froeder]

A new version is out.

2.0-alpha4 is much more stable then 1.0. So why I'm calling this alpha?? I
have no idea

Major updates on alpha4:

   - Flex-mojos was build using install mojo dependencies. Yes, we are
   buying what we are selling.
   - Released install mojo (easy way to get flex-sdk at maven repo).
   - New resource bundle system. Will blog about details latter, but keep in
   mind now dependency type is rb.swc and classifier is no longer used (so
   should be removed). See issue 49
   - Fixed commas support on asdoc. See issue 80.
   - Default SDK version was updated to 3.1.0.2710, the new milestone.


You can read more at blog:
http://blog.flex-mojos.info/2008/08/23/flex-mojos-20-alpha4/

Have a nice weekend.

  It shouldn't matter either way because when you create an instance of
  such a class you may have instance vars as well.

  However, switching from myModel.message to MyModel.message now
  generates the following errors:-

  1046: Type was not found or was not a compile-time constant: ElementFormat.
  1046: Type was not found or was not a compile-time constant: TextBlock.

  and it doesn't say which file is the cause of the error.

[flexcoders] Re: DataGridColumn trouble...

[mknuttall]

LOL. Then you don't know what a VO is.

I've done plenty of applications that function like a Flex app - and
VO's are not needed, at least not how people normally define them. If
you are talking about "projections" or "report objects" then I do use
those (see hibernate documentation). But they don't contain anything
more than convenience code.  

Of course I do multi-tiered applications so there is no "middle tier"
anymore. Business logic is needed to be performed in ALL layers.  

I do agree with your recommendation though - mostly. I have not used
Flex enough, but UI specific code (formating/etc) in Java clients
(SWT/Swing) is [correctly] handled with Renders/Providers. WinForms
sadly doesn't have this.  

If you need keep your domain objects clean then use the decorator
pattern.  

The VO/DTO pattern is majorly misused. Thankfully not so much in Java
anymore as EJB3/ORM have taken hold.

Consider using mx:Repeater for this kind of thing.  It will save you

Absolutely not true.  Perhaps it wouldn't be a pure dto, but vo's often
contain properties that are only useful to the UI.  Since you've chosen
to perform these calculations in the client, as opposed to the middle
tier; where business logic typically resides, each row of the collection
will have to be looped through anyway; either for precalculating
additional vo properties, or by using labelFunctions.  Either way, those

[flexcoders] Re: Free Flex Gauge Component

[twgonzalez]

Hi All,

Sorry I have not been tracking Flex Coders as much as I should have.

To answer some questions.

1) Yes this is the "Degrafa" gauge component.
2) I put it as v0.4 component because it is my forth release, but I have never 
personally 
regression tested it.  Usually if I put a 1.0 label on something it means I 
have run it through 
regression testing and consider it "commercial" quality.  Obviously I have 
tested it, but not 
with the rigor I would if I was shipping it commercially.

[flexcoders] Binding XML elements containing hyphens to DataGridColumns

[seanwinship]

I am trying to bind XML that has hyphens in the element names to a DataGrid.  
If I declare 
something like this:



and use the Service/Model Proxy pattern, I can load the data from an 
HTTPService.

However, I can't seem to bind other elements to the asset ID of the selected 
item in the 
DataGrid.  I've looked through the postings here and it seems that some variant 
of 
selectedItem.(@["asset-id"]) should work, but I haven't figured out the proper 
incantation 
yet.

I've also tried creating a variable in the parent document to hold the value 
and bind to that 
in other child components like this:

  public function changeHandler(event:Event):void
{
parentDocument.currentAssetID_ = 
event.target.selectedItem.(@["asset-id"]);
}

but I got some unhelpful runtime errors.

Has anyone done this successfully?

Thanks,

Sean

PS:  Yes, I am new to Flex.

[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] PieSeries label question- need more formatting control of the label.

[icodeflex]

Hello-

I have a requirement to style the text in a PieSeries label to display
with mixed sized text, colors, and fonts. I am thinking the solution
lies in a  labelRenderer for the PieSeries- which as far as I can tell
isn't supported in the "out of the box" PieSeries.

Has anyone done this before or can point me in the right direction
before I start coding this up myself?

Many thanks!

[flexcoders] Re: Vote or loose! MXML diff sucks, let's change it!

[mknuttall]

I guess i need to use tortoise more often. I use Eclipse and SVN daily
and have for years. I don't see the problem (maybe i am lucky).  

In Eclipse Ganymede, there is now a built in SVN client. It used to be
a separate product - http://www.eclipse.org/subversive/

I also noticed that people have issues with large files. I suggest
that for large files you do some refactoring and come up with smaller
files. The smaller the better especially if you have large development
teams and/or are supporting multiple releases.

RE: [flexcoders] Re: question about AMF

[Alex Harui]

It is essentailly the same problem.  Each module has a definition but
only one can be translated via AMF and if it is the wrong one you have
trouble.  So you have to use the same techniques to only have one
definition of any class used by AMF

Alex, after looking through the ppt, I do not know if this is the same
issue.

It seems to me the issue you pointed me to is when the two modules
want to share a portion of code. I.E. a singleton enforced class.

My problem seems to be different, I am actually trying to instantiate
code that has no relation between the separate modules. I am not sure
if that would cause the problem or not...

I don't understand why it would give me this error, when I am
basically saying the same thing as if I were to say

for each( var s:String in event.result )

after all DataVO is just an abstract data type.. right?

Hi,

The button bar is just a normal container that reacts to a dataProvider
collection event system.

If you know the index of the dataProvider item, just use;

var button:Button = myBar.getItemAt(index) as Button
button.enabled = false;

I can't remember if NavBar has a method that actually returns a button.

Re: [flexcoders] Preloader in a big shared library, bad idea?

[Doug McCune]

aha, I see. I think you should be good to go. As far as I know, the
preloader will get loader first and that will get added to the stage and run
while the rest of the SWF loads. Just make sure you don't use any huge
classes within your Preloader (ie don't use UIComponent or any Flex controls
in the preloader).

Re: [flexcoders] Choosing Components Dynamically

[Richard Rodseth]

You can certainly build a view dynamically, because any component can be
instantiated in ActionScript. Depending how you structure things, the code
may become quite a bit more verbose than you are accustomed to.

I believe there are some restrictions on "creation by name" in ActionScript,
but if the types of the components are known at compile time, a simple
switch statement will do the trick.

Only what you use in your app will be linked into the SWF, so if the

Re: [flexcoders] Template architecture

[Richard Rodseth]

This is working out quite nicely, but I'd like some validation. Rather than
using an init event as described here:

http://livedocs.adobe.com/flex/3/html/help.html?content=templating_3.html

I have a property setter for the template contents (or a definition object
in my more complex cases). The setter calls invalidateProperties() (and sets
_contentsChanged) and an override of commitProperties() does the actual
child manipulation. An override of commitProperties doesn't feel too out of
place in an MXML file.

By including a "contentHolder" child (or several), I can do a
contentHolder.removeAllChildren(), otherwise I would have to save off
_oldContent in addition to _newContent.

At first I hadn't related my XML-driven template to these simple ones as
described in the livedocs, but it makes sense I think. Would you agree that
the docs above should suggest the commitProperties approach ?

[flexcoders] Preloader in a big shared library, bad idea?

[Baz]

Hi,

I have a "Flex Library Project" that is the foundation for all other flex
projects in our department. It includes complex mxml components, themes,
fonts, images, assets, etc. - heavy stuff. I am now working on a custom
preloader that I would like all the applications to share and use. The
question is, should I create separate "Flex Library Project" just for the
preloader to keep the size at an absolute minimum, or is flex capable of
loading only the preloader bits during preloading if I include it in my big
fat library?

Thanks,
Baz

RE: [flexcoders] Re: DataGridColumn trouble...

Also, you can use a single labelFunction for all columns if you want.

I hear you Sefi,

However, looking at the DataGrid is like the "tail wagging the dog". 
The DataGrid is nothing more than a representation of the data,
calculated or not. Not only might it be a bit backwards, but you may
run into a race condition, by looking at what is displayed in the
DataGrid, as opposed to calculating the required column values again in
the diff column. Also, not all rows that are in the DataProvider exist
in the DataGrid; because of itemRenderer recycling.

Regardless, what I'm saying is similar to Tracy's suggestion; either
reuse the needed column calculation methods in the diff label function
(I can't imagine that this would add much overhead), pre-calculate the
column fields in your VO's, or derive a seperate collection from the raw
data; to be used for the dataProvider of the DataGrid.

Just a few suggestions,

No-one ever likes hearing that as a response to a feature request or
comment especially when its pretty basic feature that is really
shocking by its absence. 

If I had asked for the ability to embed Flash video in a cell as a
background then that is one thing but when I point out that basic
styling features are missing from the datagrid its a bit odd for you
to bring up this hoary old chestnut of a comment.

 

[flexcoders] Re: question about AMF

[tchredeemed]

Alex, after looking through the ppt, I do not know if this is the same
issue.

It seems to me the issue you pointed me to is when the two modules
want to share a portion of code. I.E. a singleton enforced class.

My problem seems to be different, I am actually trying to instantiate
code that has no relation between the separate modules.  I am not sure
if that would cause the problem or not...

I don't understand why it would give me this error, when I am
basically saying the same thing as if I were to say

for each( var s:String in event.result )

after all DataVO is just an abstract data type.. right?

RE: [flexcoders] Tabbing into Combobox in Datagrid

[Alex Harui]

If you wrap CB in a VBox, your renderer is going to be very heavy and
slow as VBox measures it and tries to layout a stack of things but the
stack has only one thing in it.  Also, the VBox is not an
iFocusManagerComponent so it won't be assigned focus.  You'd be better
off just subclassing CB, but you can wire up the VBox to be an
IFocusManagerComponent if you really need to

I want to be able to tab into the combobox.  Code for the datagrid is

RE: [flexcoders] htmlText: LI element, replace bullet w/ image?

[Gordon Smith]

In the Language Reference for the htmlText property, it says:

 

The  tag places a bullet in front of the text that it encloses.
Note: Because Flash Player does not recognize ordered and unordered list
tags ( and , they do not modify how your list is rendered. All
lists are unordered and all list items use bullets.

 

So I don't think the Flash Player supports displaying anything except a
bullet if you're using . Maybe you can use an  to display your
custom image before a .

[flexcoders] Re: DataGridColumn trouble...

[Tim Hoff]

I hear you Sefi,

However, looking at the DataGrid is like the "tail wagging the dog". 
The DataGrid is nothing more than a representation of the data,
calculated or not.  Not only might it be a bit backwards, but you may
run into a race condition, by looking at what is displayed in the
DataGrid, as opposed to calculating the required column values again in
the diff column.  Also, not all rows that are in the DataProvider exist
in the DataGrid; because of itemRenderer recycling.

Regardless, what I'm saying is similar to Tracy's suggestion; either
reuse the needed column calculation methods in the diff label function
(I can't imagine that this would add much overhead), pre-calculate the
column fields in your VO's, or derive a seperate collection from the raw
data; to be used for the dataProvider of the DataGrid.

Just a few suggestions,

RE: [flexcoders] Binding problem - not refreshing after Array.push

[Gordon Smith]

It's all about architectural layering:

 

   Flex classes (mx.*)

   --

   Flash class (flash.*)

   --

   Core AS3 classes (int, String, Array, Date, etc.)

 

Databinding is triggered by an event getting dispatched. Events are a
Flash Player concept. ArrayCollection is a Flex class that knows how to
dispatch events. Array is a class of the core AS3 language, which
doesn't know how to dispatch events.

I make an array

So I need to take care of it manualy.

Is this normal or have I forgot about something ?

Which SVN tools have you tried on the Mac? The only one I have any time with
is svnx. For the amount to time I've used it, it wasn't too bad. The only
problem I've had was when the repository was using a self-signed SSL
certificate, then I had to connect via command line and import the cert
before the GUI would work.

Have you tried any of the commercial products? I dimly remember a tool that
was doing the same sort of integration that Tortoise does but I also didn't
like it for some now forgotten reason.

[ahmad_eldardiry]

Thank you actionscript_czar for detailed answer.

I don't currently intend to sell the source code, but I just want to
make a swc which does not accidently (or intentionly) show its source
code to Flex Builder users .

I know ASV does reveal swf source code, but at least I want the
minimum level of security for swc, the one which doesn't allow regular
users to see the source code right in front of them just by debugging
their applications!

I already sold swc component (as2) knowing that it could be decompiled
by tools like ASV.

For the current swc, I just used the documented component compiler
samples (No RSL). Something like eg.:

compc -source-path . -include-classes [Class 1] [Class 2] [...] [Class
n] -output com/mywebsite/mycomponent.swc

Does that link the classes to the swc? How to prevent that?

Please advise.

Thank you.

Hi Kelly

>Why don't you just use Tortoise Diff?

I use Tortoise SVN most of the time. Instead of Subclipse which sucks
and instead of internal diff which also sucks. Tortoise SVN is a
really great tool. But we also have guys on Macs and they don't have
it. All stuff I tried for OS X is very undeveloped. And the command
line option is too hard for for them. 


>And what the hell are you doing so many Diff's for?
>Do you constantly forget what code you just wrote?

Because it is a fairly large project, several developers are making
changes to the same files. Also, we have to maintain branches to keep
the released version for quick bugfixes, feature branches and trunk.
This stuff requires a lot of merging (damn Subclipse!) and a lot of
diffing which is a killer.

Cheers,
Dmitri.

Hi Tim.

I'm not worried about duplicating code, the calculations are already
implemented in a different function, since the first two label function
use them. I want to save the computing time of doing the calculations
again...

And I do want to look at the datagrid and not the data (unless I'm

The data is raw - meaning it is the data prior to the calculations.
I want to have the data after the computations, and use it in the third
labelFunction...

I'll try and explain a bit more the situation (a bit simplified):

The raw data in the DataGrid dataprovider is VOs with various members,
Dates among them.
The second column displays the startDate after calculations (made in the
second column's labelFunction).
The third column displays the endDate after calculations (made in the
third column's labelFunction).
The forth column should display a value based on the data of the second
and third columns, but I need the values AFTER the calculations and not
the raw data. That is why I need the data in the datagrid columns
themselves (since they are the computed data) and not the raw data in

[flexcoders] Tabbing into Combobox in Datagrid

[Chilcoat, Dee]

I have a combobox in a cell in a datagrid.  Surrounding the cell with the 
combobox in it, are cells with text fields.  I can tab from cell to cell, but 
when I try to tab to the combobox, the cursor skips over it.  I want to be able 
to tab into the combobox.  Code for the datagrid is below.  The 
OtherCodeRenderer creates the combobox. I tried setting editable to true for 
that cell; the combobox gets changed to a text field when I tab into it.I 
have included the code for the OtherCodeRenderer below, also.  Any help will be 
appreciated.  Thank you.

RE: [flexcoders] Dynamic menu that reconfigures in realtime - ideas for approch?

[Tracy Spratt]

I suggest using XML for the Menu dataProvider, since both are inherently
hierarchical, plus XML gives you the e4x expression syntax for locating
nodes.  

 

The general way to modify a menu is to change the dataProvider.  You can
replace it completely, or use an e4x expression to find the node you
want, then set its attributes as needed.

 

This is pretty standard stuff, there should be some examples out there.

Hi all,

For example: The user ticks checkboxes for the year 2006 and 2007 and
the vertical menu then shows the links for projects for that year.
Tick off one, and the menu reconfigures with the appropriate content.

Some thoughts I have is to read all project info from an xml-file into
an ArrayCollection to populate the menu.

The logic of displaying only part of the ArrayCollection in the menu
according to user selection is what I have problems figuring out.

RE: [flexcoders] [video included] Datagrid recycle issue? How can I 'force' it to re-render

[Alex Harui]

The renderers have a data property which gets refreshed under certain
situations.  They then follow the component lifecycle in updating their
display.   In theory the setter for the data property must be hit when
you see things go bad.  The DG has a makeRowsAndColumns method that
typically does the refresh.  It might be interesting to find out if and
why it gets called when things go bad.

I understand that the datagrid is recycling cells, makes sense. I've

Oddly enough, you can see that the datagrid refreshes correctly when I 
interact with display objects other than the grid itself.

[flexcoders] Accessing button properties from the ToggleButtonBar

[fumeng5]

Hi.

I want to set properties for each element in my ToggleButtonBar's
dataprovider, i.e. enabled, visible, etc...

Something like this:

(myToggleButtonBar.dataProvider.getItemAt(0) as Button).enabled = false;

But that doesn't work. 

I know the dataprovider of a ToggleButtonBar has to be a String,
Array, or IList. I already tried setting the dataprovider to be a
collection of buttons. 

So, is it possible to set button properties on my ToggleButtonBar?

Thanks for any tips,

fumeng. 

Re: [flexcoders] Re: DataGridColumn trouble...

[Sefi Ninio]

Hi Tim.

I'm not worried about duplicating code, the calculations are already
implemented in a different function, since the first two label function use
them. I want to save the computing time of doing the calculations again...

And I do want to look at the datagrid and not the data (unless I'm missing
something).
The data is raw - meaning it is the data prior to the calculations.
I want to have the data after the computations, and use it in the third
labelFunction...

I'll try and explain a bit more the situation (a bit simplified):

The raw data in the DataGrid dataprovider is VOs with various members, Dates
among them.
The second column displays the startDate after calculations (made in the
second column's labelFunction).
The third column displays the endDate after calculations (made in the third
column's labelFunction).
The forth column should display a value based on the data of the second and
third columns, but I need the values AFTER the calculations and not the raw
data. That is why I need the data in the datagrid columns themselves (since
they are the computed data) and not the raw data in the dataprovider...

Hope that makes the situation clearer, hopefully will help you guys help me
:)

Thanks,
Sefi

No-one ever likes hearing that as a response to a feature request or

shocking by its absence. 

If I had asked for the ability to embed Flash video in a cell as a

Odd that this never came up when I was searching. None of the coders

I'll have a look at that to see if it helps simplify my code.

Nope, That's how Eclipse and Beyond Compare have always interacted, through
a plugin. It's not a workaround, it's using the builtin capabilities of the
platform to add functionality. The same way it's able to work with mxml and
actionscript. Do you think that Eclipse comes with code-hinting for MXML?
No, it's there because some bright Java programmers used the innate
functionality of Eclipse to allow it to do more than the stock distribution.

No, but that's irrelevant as we're not talking about my Passat, we're
talking about Flex Builder and Eclipse.

Never said it was just the two things mashed together. I'm sure there are
issues with the code from Adobe. But those are the things that deserve to be
logged in the Adobe bugs db, not stuff about code they didn't write.

To turn your analogy around, if I use Flex Builder to write Java code and I
have an issue there, should I harangue Adobe about it? No. I should send the
issue to the Java EE team at the Eclipse Foundation.

I understand that the datagrid is recycling cells, makes sense. I've
checked out Alex's blog, but can't find a solution to this situation.

Oddly enough, you can see that the datagrid refreshes correctly when I
interact with display objects other than the grid itself.

What events are being fired by the other display objects that are
causing the grid to 'refresh'.

First of all, if you don't distribute the source code with your SWC 
file most people won't see it.  You probably saw it because you have 
the library linked ( even if it was closed ) or the source files 
linked to the SWC build path.

Secondly, SWC and SWF files can be easily decompiled using a tool 
like Buraks Actionscript Viewer.  This however does not limit your 
rights as the creator of the code, it just means people can get to 
it.  Most people won't though as they have better things to do and 
projects to get done.  Some will though and it may or may not be 
worth the extra effort( think ROI ) to attempt to stop them.

I think this is the reason that some companies offer to send the 
source as well ( but limit your priveleges with the source in the 
license ) for a premium over the price of just the component alone.  
This might be smarter. It gives people a legal way to get the source 
for your components so they can push your components past their 
initial design constraints while giving you more cash for your work.

Ultimately the decision is up to you.

[flexcoders] Re: Error styling datagrids

[pixelgeek]

> That already exists in AdvancedDataGrid.

Odd that this never came up when I was searching. None of the coders
here locally seem to have much experience and the solution that was
sent to me involved itemRenderers which I am currently using.

I'll have a look at that to see if it helps simplify my code.

Why is there an AdvancedDataGrid? Did someone at Macromedia/Adobe
attempt to fix issue with the basic DataGrid?

I just like when everything works. It worked before, now it is broken.
And surprisingly, I am not happy with this fact, as instead of doing
what I used to do I have to find some workarounds.

I am pushed anyway to use Tortoise SVN directly without Subclipse, but
I can't stand seeing Mac guys suffering from this bug.

So, when your car breaks, do you call directly Bosch AG and ask why
this bloody alternator stopped working? I think you would simply send
your car to the dealer you've bought the car from. :)

FB is not a just an Eclipse & Flex SDK tied up together. Look at the
Adobe bugs db - there are hundreds and hundreds of bugs just for the
Builder itself.

That already exists in AdvancedDataGrid.  Where it falls down is that 
most of the default itemRenderers don't support background styling.  If 
it doesn't exist in DataGrid, it's pretty easy to add like this 
http://flexdiary.blogspot.com/2008/08/tilelist-with-
stylefunction.html.  For more about the problem with the itemRenderers 
not supporting background color and alpha, check out the Musings on 
AdvancedDataGrid series.

RE: [flexcoders] [video included] Datagrid recycle issue? How can I 'force' it to re-render

[Alex Harui]

You will have to debug your situation.  There's no way to tell from a
video what events are firing.  If the dataProvider or any of a number of
properties change, the DG will update all the rows.  The real question
is whether you've handled recycling correctly or if there is some other
problem.

Oddly enough, you can see that the datagrid refreshes correctly when I

Eventually, it would.  If we added every feature requested by our
customers, datagrid alone would be over 1MB of SWF and not run very
fast.

 

The ADG has some styling capabilities.  DG has methods you can override
to do some things.  My blog has some example renderers that do some
styling.

All I'm saying is that you should lay the blame where it really belongs.
It's not like Adobe wrote the Compare functionality in FB3, they're using
what's already in Eclipse (font changes notwithstanding). If you want to
point out to the Eclipse community that you think their diff functionality
sucks, then you are probably going to get more traction over at
eclipse.org(but not if it's phrased that way :-) ).

[flexcoders] SWCs become invisible in Design View

Did anyone hit the problem with getting SWC contents shown in the

At some of point of time (I presume with project growth), SWC contents
are disappeared from Design View. And there is no Red Cross mark like

point a mouse to it or move it.

[flexcoders] Re: DataGridColumn trouble...

You don't want to look at the grid, you want to look at the data.  My
suggestion would be to pull the complex calculations out of the label
functions and put them in seperate functions; that are called by the
label functions.  That way ou can re-use the calculations where needed,
and not worry about duplicating code.

[flexcoders] Column Chart Label Renderer

[mburtless]

Hi guys,
I've read the posts on this board for a long time, but I've never had
the need to post until now.  As some of you may know Flex doesn't like
to show data labels on column charts which are placed inside cartesian
charts.  Doesn't like to, as in won't.  To get around this I wrote my
own item renderer which extends boxitemrenderer (I was lazy and didn't
feel like writing my own renderer from scratch).  The data labels post
now and it works great, until I resize.  On resize the columns will
scale, but the labels stay in one place.  My updatDisplayList method
is below.  If anyone can help I would greatly appreciate it!!

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

super.updateDisplayList(unscaledWidth, unscaledHeight);

//If the item is really a chart item
if (parent is UIComponent) {

var parentID:String = String(parentSeries.id);
var yField:String = String(parentSeries.yField);
   
   
//If the textfield hasn't been initialized AND the item is NOT a
legend item 
if( !textField && ! isLD){
textField = new TextField();

var tf:TextFormat = new TextFormat();

//Get color of text from CSS
tf.color = getStyle("color");
//Set the rest of the text field properties
tf.font = "Verdana";
tf.align = "center";
tf.bold = true;

textField.x =  (unscaledWidth / 2) + this.x - (textField.width / 2);
textField.y = (unscaledHeight / 2) + this.y;


textField.defaultTextFormat = tf;

//Set the text itself
if(item.item.hasOwnProperty(yField)){
textField.text = String(textField.x);

}
parent.addChild(textField);
}
}
}

Maybe we don't think it's Adobe's responsibility to change something that
they didn't write. The Compare tool is a base Eclipse function. If you don't
like the font choice, why not change it in the Preferences? I haven't
noticed that it was so terrible.

And if you really don't like it that much use the External Tools Plugin and
BeyondCompare.

C'mon, guys! I don't believe that I am the only one who uses Compare
tool in Flex Builder. 
There was even an article in Cosmo that it's becoming popular among
AIR developers to use Compare tool before checking their cool stuff
into SVN :)

Re: [flexcoders] Template architecture

[Richard Rodseth]

I'm a big fan of the Eclipse plug-in model, though it's been a while since I
looked at how they do Perspectives, for example.

I take Alex's point (I think), but I'm not sure we're on the same page
regarding what is "the model". The end goal is that a configuration file
(XML, say) could describe a layout by specifying a template and a bunch of
things to place at various named locations in that template. By definition,
the config file has to know the names of the locations, so I don't see how
that is a violation of encapsulation. To validate the description, one needs
that knowledge. I suppose if one had a layout editor (something I'm not
planning at this time), once you'd filled in a template, it could persist
the description, but then the layout editor would need that knowledge. The
list of places you can put stuff *is* part (all) of the interface of the
template.

However, I am persuaded to make a template base that consumes a "description
model". That's basically what I was doing in the DynamicLayout that contains
(and creates) the template instance.

Thanks for the input.

You may want to consider an approach similar to this:
http://blog.tsclausing.com/post/19

I actually use filters and data functions on my axes/series to change 
the way the data appears, instead of changing out the separate data 
source.  If you contact me off list (amy at magnoliamultimedia dot 
com), I can send you some code that shows this.  But I don't have 
time to strip it of the client-specific stuff to make it a public 
example, so I'm not going to post it.

Just go back to page 1 of the article you reference and the link to the flex
