RE: [flexcoders] Re: Flex woes, wo-iz-o, i hate it (sometimes)
You can tell the compiler to include classes that follow the [Mixin] pattern, but that's too much overhead for a general class loader thing. The pattern is very simple. It is: import mx.containers.VBox; VBox; import mx.controls.TextArea; TextArea; etc. You could probably write a script that generates it, but really that just bloats your SWF. The framework RSL is 600K, charts and ADG are a whole bunch more, RPC is more and LCDS is even more. Using the shared RSL will cause more classes to be around just-in-case, but if you need your custom classes loaded on-demand, you'll just have to build out that modules-as-class-loader idea Start with what you need and get everything else later when you need it, -Alex From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Josh McDonald Sent: Wednesday, July 30, 2008 4:45 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Flex woes, wo-iz-o, i hate it (sometimes) You can tell the compiler to include any class you want, as well as whatever it thinks you want, right?

RE: [flexcoders] Can we subclass Application yet?
There is one pattern where you declare a new default property for the MXMLComponent, new children get stuffed in there, and when you get instantiated you add those children. It works, but feels rough around the edges. Changing the compiler to add any children won't really work if you are trying to insert the children between a menubar and status bar.

[flexcoders] Any future plans to support ODBC Connections for AIR applications?
I know this has come up before but there is a significant need to access data in desktop databases (Read Only would be OK). (e.g. I am working with the Google App Engine and there is no easy way to populate their datastore). A GUI upload app written in AIR could be great for this. I've thought about doing a small GUI in Python since the libraries are available - however I'd prefer to use AIR for GUI development. While support for this may not be available out of the box I wondered if some 3rd party libraries might be available for this - e.g. Python has extensive libraries than can be used to access Excel, Access etc. Any chance that similar Flex/AIR/Actionscript libs might be developed? Anyone else out there thought about doing this? TIA, Patrick

RE: [flexcoders] permission based ui
Actually, I do this all the time with a viewstack. The way I do it is I have
the main application check the security and setup a security level
parameter. Then, I pass this secLevel to the component that contains the
viewstack. In the viewstack component, each view in the viewstack is its own
component, so you can use the includeInLayout and visible properties of the
component to show it or not show it based on the value of secLevel. Works
like a charm.
Main.mxml
mx:states
mx:State name=checkSecurity
mx:AddChild
...show only a progress bar to the user while checking the security in
ActionScript
...you setup the secLevel
/mx:AddChild
/mx:State
mx:State name=mainApplication
mx:AddChild
comps:MainApp id=mainApp secLevel={this.secLevel}/
/mx:AddChild
/mx:State
/mx:states
MainApp.mxml
mx:ToggleButtonBar id=mainButtonBar dataProvider={vs}/
mx:ViewStack id=vs
comps:FirstButton id=first/
comps:SecondButton id=second/
comps:ThirdButton id=third/
comps:Setup id=setup includeInLayout={(secLevel == 0)?true:false}
visible={(secLevel == 0)?true:false}/
/mx:ViewStack
And, voila, you only see the Setup button if you're secLevel is 0.

I don't think there's a way to directly get a reference to the My

but the code will be different on XP and Vista:
var directory:File = File.documentsDirectory;
if (Capabilities.os == Windows XP) {
directory = directory.resolvePath(My Music); // On XP
} else {
directory = directory.resolvePath(Music); // On Vista (and Mac?)

[flexcoders] Re: Integrate flex and Java
Venkat, You need to be looking at the middleware which sits between backend like Java and Flex Front End. Here are the few popular ones: http://opensource.adobe.com/wiki/display/blazeds/BlazeDS http://www.themidnightcoders.com/weborb/java/ Once you get an understanding of these, you will know better. Java understands Java Objects, and Flex understand ActionScript Objects (and other things). This middleware does the magic of converting Java POJOs - AS Objects and vice versa. You can integrate these middleware solutions with an existing Java webapplication. I wrote this small how-to some time back, http://meriyatra-blog.blogspot.com/2008/07/flex-how-do-i-integrate- blazeflash-with.html but you will also find loads of material on the web, if you look.

[flexcoders] Re: Creating advanced components
Well you don't *have* to override these methods as Panel already
implement them (and so does UIComponent).
It depends on what you are trying to do. If you need to create new
objects within the extended panel, then you'll want to override
createChildren(), if you want to update these children, then override
updateDisplayList(), etc.
In all cases, always make sure you call the method of the parent class
using super.methodName() in order not to break the default behavior of
the component.

[flexcoders] NaN and Infinity showing in output - How to modify?
I seem to have trouble explaining myself here, hard when you are just
learning. Perhaps this will be better.
Is it possible to remove, change or hide any label or text output that
displays NaN or Infinity?
I'm performing a very simply calculation where the user enters a
number in a form and it is calculated and displayed. Simple and does
what I need. In some instances, there are more variables required and
until they are provided, the output display NaN or Infinity.
How could I easily adjust these? It could be a default display of
zero, it could be to display nothing, whatever is the easiest and most
straight forward method.
Below is only an example of how I'm taking the user input from the
form and passing the variable on to the Label text output.
mx:Number id=myNumber{Number(userInput.text) * (1 +
Number(otherUserInput.text)) * 1 /
Number(otherOtherUserInput.text)}/mx:Number
The answer is output to:
mx:Label text={PrepForDisplay.format(myNumber)}/

[flexcoders] Keyboard navigating through List's item renderers
Hi, I have a list that renders meta data about images (title tags). This list uses a Form with 2 TextInput controls as an item renderer. The user should be able to navigate through the input fields using either the mouse or the tab key. The List default behavior when editable=true is to set the focus to the renderers themselves, but not to their sub components, so the Form itself will have a focus rectangle but not the TextInput controls. What I tried to do is to override the setFocus() on the Form subcomponent and move the focus to the first TextInput and on that TextInput focusOut set its focus to the 2nd TextInput. That didn't work as expected, and even if it did, I'm sure the is a better way to achieve this behavior. Thank you, Almog Kurtser http://www.mostlyflex.com
Re: [flexcoders] NaN and Infinity showing in output - How to modify?
If the format function is a custom function you have written, you could just
have it check whether you like the result it is about to return, and if not,
return something else. If that is not the case, I believe that you should be
able to put tests into your binding statement.
You could test for NaN with something like this:
mx:Label text={(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber) }/
I'm not sure about infinity, but I assume that you can test for this by looking
for the greatest possible value of the number. Assuming that you have set up
the variable maxValue to contain that value, you should be able to do something
like this:
mx:Label text={(myNumber maxValue) ? 0 : PrepForDispl ay.format( myNumber)
}/
If you put the two together, it would look something like this:
mx:Label text={(myNumber is NaN) ? 0 : (myNumber maxValue) ? 0 :
PrepForDispl ay.format( myNumber) }/

Hi Alex, yes in MXML - since we have a debug toolbar that appears on every view based on a flag, I wanted to put this visual component on the base Application class along with common public vars etc. Public vars etc work fine, but it seems as though you cannot put any visual mxml components on the base class.

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Hi Sid, thanks for the reply. I tried your first solution since I did not
create a custom function and it returns;
1067: Implicit coercion of value of type Number to an unrelated type Class
I have a vague understanding of what is occurring here. Any way around it?
How difficult would it be to modify or create a custom function?
What I have now is simply:
mx:NumberFormatter id=PrepForDisplayprecision=2
rounding=updecimalSeparatorTo=.thousandsSeparatorTo=,
useThousandsSeparator=trueuseNegativeSign=true/

If the format function is a custom function you have written, you could just
have it check whether you like the result it is about to return, and if not,
return something else. If that is not the case, I believe that you should be
able to put tests into your binding statement.
You could test for NaN with something like this:
mx:Label text={(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber)
}/
I'm not sure about infinity, but I assume that you can test for this by
looking for the greatest possible value of the number. Assuming that you
have set up the variable maxValue to contain that value, you should be able
to do something like this:
mx:Label text={(myNumber maxValue) ? 0 : PrepForDispl ay.format(
myNumber) }/
If you put the two together, it would look something like this:
mx:Label text={(myNumber is NaN) ? 0 : (myNumber maxValue) ? 0 :
PrepForDispl ay.format( myNumber) }/

[flexcoders] Chart: pass info about series1 to series2 lineSegmentRenderer callback?
First question is whether I can pass actual parameters to a callback in the first place? This is what I need to do: mx:ColumnSeries id=salesSeries yField=sales /mx:ColumnSeries mx:LineSeries id=percSeries yField=percent lineSegmentRenderer=PercentLineRenderer(orig callback params, new callback params) /mx:LineSeries Conventionally of course the lineSegmentRenderer gets no params as a callback. But in this instance I need to manipulate the position of the percent line series lines through the renderer based on sales series data so that the lines are positioned exactly over the columns of the sales series. I have code in the renderer that positions the lines, but different underlying data for the column series (2 side by side cols for each data point), changes the width and horizontal position of the columns and then the percent line fragments above no longer line up. If I could get the sales series info to the percent series renderer I think I stand a chance of coding interacting series A big thank you in advance, Mic.

[flexcoders] Re: Chart: pass info about series1 to series2 lineSegmentRenderer callback?
I don't believe you can pass params. An alternative would be to have
your lineRenderer query upwards for the data. I do something similar
and added the following code in my updateDisplayList();
(I don't know how important the initial LineSeries check is)
override protected function updateDisplayList(wd:Number,ht:Number) {
var lc:LineChart;
if (parent is UIComponent) {
var myParent:String = String(UIComponent(parent).className);
if (myParent !=LineSeries)
return;
var ls:LineSeries = parent as LineSeries;
lc = ls.owner as LineChart;
var salesInfo:Number = lc.getSalesInfo(); // talk to lineChart here

Subject: [flexcoders] NaN and Infinity showing in output - How to modify?
I seem to have trouble explaining myself here, hard when you are just
learning. Perhaps this will be better.
Is it possible to remove, change or hide any label or text output that
displays NaN or Infinity?
I'm performing a very simply calculation where the user enters a
number in a form and it is calculated and displayed. Simple and does
what I need. In some instances, there are more variables required and
until they are provided, the output display NaN or Infinity.
How could I easily adjust these? It could be a default display of
zero, it could be to display nothing, whatever is the easiest and most
straight forward method.
Below is only an example of how I'm taking the user input from the
form and passing the variable on to the Label text output.
mx:Number id=myNumber {Number( userInput. text) * (1 +
Number(otherUserInp ut.text)) * 1 /
Number(otherOtherUs erInput.text) }/mx:Number
The answer is output to:
mx:Label text={PrepForDispl ay.format( myNumber) }/

[flexcoders] Re: Chart: pass info about series1 to series2 lineSegmentRenderer callback?
Unfortunately, the data property in a chart itemRenderer, only contains
the xField and the yField; because it is a ChartItem. However, assuming
that both series relate to each other by a common xValue, you could use
that to iterate over the first series dataProvider to get the related
item; assuming that the dataProvider is public and hopefully in a model.
private var _chartItem:ChartItem;
public function get data():Object {
return _chartItem;
}
public function set data(value:Object):void {
if (_chartItem == value) return;
_chartItem = ChartItem(value);
if(_chartItem != null)
if (ColumnSeriesItem(_chartItem).xValue != null)
var myCommonXValue : String =
ColumnSeriesItem(_chartItem).xValue.toString();
// then loop through the first series
dataProvider, comparing the xValue, to get the associated sales value
}

If the format function is a custom function you have written, you could just
have it check whether you like the result it is about to return, and if not,
return something else. If that is not the case, I believe that you should be
able to put tests into your binding statement.
You could test for NaN with something like this:
mx:Label text={(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber)
}/
I'm not sure about infinity, but I assume that you can test for this by
looking for the greatest possible value of the number. Assuming that you
have set up the variable maxValue to contain that value, you should be able
to do something like this:
mx:Label text={(myNumber maxValue) ? 0 : PrepForDispl ay.format(
myNumber) }/
If you put the two together, it would look something like this:
mx:Label text={(myNumber is NaN) ? 0 : (myNumber maxValue) ? 0 :
PrepForDispl ay.format( myNumber) }/

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Actually, if you are just going to hide the label field, you can just have it
display the result of the formatting, and put the checking for NaN and infinity
into the setting for visibility. Since you are going to hide the label and it
has a value you don't like, you don't really care what it is displaying when it
is invisible.

Re: [flexcoders] NaN to return a string?
Sure, just replace the 0 with whatever text you want, putting it inside single
quotes since the entire statement is inside of double quotes. Since you are
setting the value of a label, what ever you put in is going to be cast to a
string anyway.

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Hmm, sorry the last post left a part out, it was shown lower down:
mx:Label ... text={isNaN(mynumber) ? 0 : PrepForDisplay.format(mynumber)}
... /
Adding the ³² as you stated, returns an error for mx:Label, ³² or ³/².
The zero is what is display in the application, if I could provide a short
string instead, it would be ideal. Even if the initial default text of the
label was ³whatever² until a calculated value was entered. But there are
many, many of these calculations to perform and I would like to find the
simplest answer. Close though, thanks for the help.

[flexcoders] Types in Web Services
I have a method in java that returns an object of type T which has a SetString When I import the Web Service in Flex Builder 3, it creates a class T with an atribute of type Array When I call the method the Array always has size 0. Is there anyway to fix this without having to change the type in the Java code. Thanks.
[flexcoders] Re: NaN and Infinity showing in output - How to modify?
to possibly help in the vague understanding, the ()?: stuff is an
inline if statement. (mynum maxval) ? is like saying If mynum is
greater than maxval. : is the else.
re your errors: from eyeballing everything, numberformatter.format
returns a string (control click into .format in flexbuilder to see
the framework code). I could be making this up, but NaN might be a
class too, so it is probably the cause of your coercion error. I
would break out everything into a function that returns a string (for
the text property of your label), so the last part would be return
PrepForDisplay.format(mynum).toString() (or as String).
Good Luck

[flexcoders] SQL crashing program
I have this weird deal going on right now. I'm running through a for loop creating a bunch of sql statements (within an exclusive transaction) with eventlisteners for the results and errors. The result eventlistener is relaying the status of the progress through the sql statements (record x of y inserted). The program crashes when I run the program, but when I put code in the result eventlistener to write sql.text to a file (trying to see if there is a bad sql statement crashing the program) it stopped the program from crashing and everything works well. I don't understand why that would be. The only thing I can think of is that there is some timing issue that I'm skirting around with writing to a file in between each sql statement. Does anybody have any idea why putting the code to write to a dblog file would make the program work? I'm sure it's is just that piece of code as well.

An event is probably the easiest way.

RE: [flexcoders] Re: Sorting an XMLList on an attribute
Yes, you really should not use XMLList as a dataProvider. *It is not
bindable* and does not dispatch the necessary events to update the UI.
By the way, this is clearly stated in the docs, and I repeat it on this
list very often. (Do not use Array, for the same reason)
You need to make the change now, it will not get any better. Also, I
suggest you use XML for the tree dataProvider. It is inherently
hierarchical, instead of the nested lists you get with
XMLListCollection. You can still break out a node into an XMLList or
XMLListCollection as needed in the code. Just a matter of taste, though.

Hi Tracy,
Thanks a lot for replying. That cleared a lot of my confusion between
XMLList and XMLListCollection. Based on your example I am able to sort
the XMLList. But there is one issue I observed. I have to reset my tree
dataProvider after sorting the XMLList (tree.dataProvider = booksList).
If I do not do that certain duplicate values start appearing in the tree
on multiple invocations of sort. I am not sure whats causing this as the
actual tree dataProvider (bookList) always remains in a consistent state
even after multiple invocations of the sort. My dataProvider is Bindable
so should not tree always represent the current state of the
dataProvider (bookList) without my resetting the dataProvider. Please
let me know if I am missing something.

That's it for now :) Haykel --- In flexcoders@yahoogroups.com, Gordon Smith [EMAIL PROTECTED] wrote: Hi, Haykel. In current builds of Gumbo, you can set all FXG text attributes (plus verticalAlign) on what we consider the Gumbo text primitives: TextBox, TextGraphic, and TextView. You have to currently set them as properties, not CSS styles; support for CSS will come later, probably within a month or two. Higher-level components like the Gumbo Button, TextInput, TextArea, etc. do not yet support setting text attributes. You have to work on the primitive in their skin. This will be fixed in the same time frame. Astro's text engine is known as FTE (Flash Text Engine). It does not support a markup language. TCAL, the Text Component ActionScript Library, which implemented in the three text_xxx SWCs, adds support for a markup language which is a superset of FXG. I'm not sure whether we have published the spec for FXG or not yet. (Do you know?) I don't think we have a spec for the superset that TCAL supports, but you can see TCAL's API by looking at the ASDoc for the text.* packages in the Gumbo ASDoc at http://livedocs.adobe.com/flex/gumbo/langref/. I'm happy to hear that you're interested in Gumbo's text features. I'm the engineer who is integrating FTE and TCAL into the Flex framework. Gordon Smith Adobe Flex SDK Team
Re: [flexcoders] Re: NaN and Infinity showing in output - How to modify?
I think I see your point here, and I guess that I have not made mine clearly
enough, so here is a little more on this.
When we say text={myNumber}, we are really setting up whatever is within the
braces as an event handler for the event dispatched whenever myNumber changes.
If we think of binding as setting up that relationship, then yes, everything in
this thread is using binding. However, I think it is common for beginners to
think of that statement as binding the text attribute to the latest value of
myNumber, and to think of binding as doing no more than such assignments.
I think it is important part of learning flex to realize that one can do much
more than that. In the largest sense, one can do almost anything that is
possible with a single ActionScript statement, so long as it returns a valid
value for the attribute to which it is assigned, in this case the text
attribute. For example, one could do something rather complicated, like this:
text={(myNumber != 0) ? myFunction() : myOtherFunction()}
So long as both functions returned a value that could be validly assigned to
the text attribute, this approach is valid, and we can obviously do any valid
ActionScript within either function. I'm not sure that this approach would be a
best practice, but the point is that we are doing a lot more than simply taking
the value of myNumber and assigning it to text.
Finally, although I do not think you meant to imply this, I think it is worth
saying that one cannot use ActionScript within an assignment to an MXML
attribute without using braces. Well, one can, but it will be treated as a
string, not as code to be run.

But in this instance I need to manipulate the position of the percent line series lines through the renderer based on sales series data so that the lines are positioned exactly over the columns of the sales series. I have code in the renderer that positions the lines, but different underlying data for the column series (2 side by side cols for each data point), changes the width and horizontal position of the columns and then the percent line fragments above no longer line up. If I could get the sales series info to the percent series renderer I think I stand a chance of coding interacting series A big thank you in advance, Mic. -- j:pn \\no comment

[flexcoders] LCDS - Tomcat - JOTM Integration
After a couple days of fussing around, I was able to successfully
integrate JOTM into our webapp, and thought that I'd share what I did.
Hopefully it will be useful to someone else.
Environment:
Eclipse 3.3.1.1
Tomcat 6.0.16
LCDS 2.5.1
JOTM 2.0.10
Installation:
1) Download JOTM 2.0.10 from http://forge.objectweb.org/projects/jotm/
if you don't already have it.
2) Unzip to c:\
3) Link those jars to Tomcat
a. Double-click Tomcat definition in the Servers tab of Eclipse.
b. Click Open launch configuration.
c. Select the Classpath tab.
d. Select User Entries, and then Add External JARs.
e. Navigate to C:\jotm-2.0.10\lib.
f. Select all classes except commons-logging.jar and log4j.jar.
g. Apply the changes and exit Tomcat properties.
h. (optional) test JOTM installation by starting the server and
accessing the below JSP file*. Success will be obvious.
4) Edit your META-INF\context.xml to include the following line:
Transaction name=UserTransaction auth=Container
factory=org.objectweb.jotm.UserTransactionFactory jotm.timeout=60/
You should now be able to perform create, delete, and update
operations on a managed collection of a DataService.
* Optional JSP file(I got this from someone in this forum, but can't
remember who)
%@ page import=javax.transaction.UserTransaction %
%@ page import=javax.naming.InitialContext %
%@ page import=javax.naming.Context %
[EMAIL PROTECTED] import=javax.naming.NamingException%

UserTransaction userTransaction = (UserTransaction)
ctx.lookup(userTransactionJndi);

[flexcoders] Can see series[0].seriesRenderData in debug - cannot code to it?
Hi all,
Thanks very much for all your help so far ... I am now accessing the
chart object from within the line renderer with:
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
var lc:ColumnChart;
var ls:LineSeries = parent as LineSeries;
lc = ls.owner as ColumnChart;
In examining debug, I found
lc.series[0].seriesRenderData of type ColumnSeriesRenderData which
Represents all the information needed by the ColumnSeries to render
and within that
seriesRenderData.renderedXOffset, The offset of each column from its x
value, in pixels;
seriesRenderData.renderedhalfWidth,Half the width of a column, in pixels;
Thinking that I was now cooking with gas/petroleum/ethanol/mazola I coded
var renderedXOffset:Number = lc.series[0].seriesRenderData.renderedXOffset
to find that any reference to .seriesRenderData creates an error. If I
can see this dot notation in the debug variable pane, shouldn't I be
able to code it? Again TIA,
Mic.

Hello Group
I would like to select an Editor for each cell in my DataGrid

I believe I can use the itemEditBegin event to assign and create my

I know the following doesn't work - I just posted it to show that I am

Any assistance greatly appreciated!

When we say text={myNumber}, we are really setting up whatever is

whenever myNumber changes. If we think of binding as setting up that

However, I think it is common for beginners to think of that
statement as binding the text attribute to the latest value of
myNumber, and to think of binding as doing no more than such
assignments.
I think it is important part of learning flex to realize that one
can do much more than that. In the largest sense, one can do almost
anything that is possible with a single ActionScript statement, so
long as it returns a valid value for the attribute to which it is
assigned, in this case the text attribute. For example, one could do
something rather complicated, like this:
text={(myNumber != 0) ? myFunction() : myOtherFunction()}
So long as both functions returned a value that could be validly
assigned to the text attribute, this approach is valid, and we can
obviously do any valid ActionScript within either function. I'm not
sure that this approach would be a best practice, but the point is
that we are doing a lot more than simply taking the value of myNumber
and assigning it to text.
Finally, although I do not think you meant to imply this, I think
it is worth saying that one cannot use ActionScript within an
assignment to an MXML attribute without using braces. Well, one can,
but it will be treated as a string, not as code to be run.
In at least some instances, MXML will run code that is not within
braces, for instance
mx:LinkBar id=chartSwitcher borderStyle=solid
itemClick=invalidateDisplayList() /
It's not treating the text within the itemClick property as a string,
but as code to be run. I'm not certain exactly where the line is,
but you don't ALWAYS have to enclose your as expressions in brackets
to get them to run.

[flexcoders] problem adding images to UIComponents using AS3
I don't get why this code is failing, it's reproducible if you put an image in
the path shown below. (This isn't the actual code in my app, I just isolated a
problem and made the problem reproducible it here. In my real app, it's
failing to embed an image into a class that is added to a UI component. The
class extends Sprite).
The first Image class instance declared with MXML embeds the image just fine.
The second, using a UIComponent and adding an instance of the image class to it
fails. Why? See comments in the code below:
?xml version=1.0?

Re: [flexcoders] Re: NaN and Infinity showing in output - How to modify?
True. Good point. Event handler attributes are assumed to contain code. Most
attributes are of a type like string or number, and will need braces to get a
value treated as code. I'm not sure if there are other attributes beside event
handlers which are also assumed to contain code, but it wouldn't surprise me if
there are some others.

[flexcoders] Multi-line repeated graphics
I have a requirement for a data visualization that involves a graphic repeated n times as follows, over multiple lines/rows. x x xx However, it should also never scroll, and fill whatever space is available, with the cell size varying as necessary, with aspect ratio preserved. I've experimented with two approaches: 1) using Degrafa as an item renderer for a TileList 2) Tile with Repeater, with Degrafa object inside Repeater 2) is promising, and as someone on the Degrafa list suggested, I could render at a fixed reference size, and apply a scale to the container. The overhead of the repeater approach is obviously a concern, but the challenge with 1) is dynamically determining the cell size so that the component doesn't scroll. I can't turn off clipContent, since TileList is not a container. I feel the need for a Degrafa extension or yet another custom tiling component, but my other one hasn't exactly been a walk in the park, so ideas are welcome.
Re: [flexcoders] problem adding images to UIComponents using AS3
There is probably more to it than this, but note that the action script
language reference listing for UIComponent says, The UIComponent class is not
used as an MXML tag, but is used as a base class for other classes.
My suspicion is that it does not contain the logic needed to properly display
children that are added to it, and that its descendents provide this logic.
