Subject: [flexcoders] Popups and accessibility (JAWS)

 






Dear All,

I've been assigned the task of testing and fixing accessibility tasks in a Flex 
3 application. One of the problems we're having is JAWS not reading popup 
windows. The Alert control works (when the alert pops up, title, message are 
read, focus is on the default button, and the default button's label is also 
read, all without any user intervention, e.g. moving focus with TAB). However, 
popup windows created in other ways (e.g. the sample at 
http://livedocs.adobe.com/flex/3/langref/mx/containers/TitleWindow.html 
 ) do 
not: the popup is shown, but JAWS does not read anything.

Are we doing something wrong, is there some special setting that we need (or 
perhaps JAWS treats Alert in a special way)? We have a popup window component 
that handles user confirmations, having a configurable number of buttons, a 
title and a text message. I've tried setting focus (setFocus() and 
drawFocus(true)) on the window or the Label component used to display the 
message, and it's OK on the screen but JAWS does not read anything.

Thanks in advance,
István

RE: [flexcoders] module loading and progress load slow?

[Gregor Kiddie]

Do you have a lot of RSLs for each module? Our experience was that it
wasn't the loading of the module that took the time it was loading all
it's RSLs.

loading modules 

I've been rearranging my application to use modules to reduce load time
and prepare it to handle later larger development etc...
All is well I've got it loading modules and such and learned a lot over
the past few days. 

I have several modules that have large images it uses with source= and
some other swf's it loadsI prefer not to allow caching since these
items change a lot.

On a localhost connection (dev) It can take 10 seconds to load the
module etc.
At first I thought it was needing a preloading technique that adobe
offers so i tried that to load while the app loaded etc.. no go

then i tried to see if i could add a progress bar on top of the module
loading so the user is at least informed but to my dismay it loads too
fast for the progress bar to show up

heres the size of the swif being loaded
364K 2009-04-23 13:54 nutrition.swf

the images and other swfs that load into this module are about 1-2 megs
total. 

If i avoid using modules it loads on localhost almost instantly :(

I have a feeling the source = for images and swf loading is whats
dragging it to load fast.

What options do i have for either preloading quicker for this module?
Is it possible that my custom component is causing this performance
issue?

[flexcoders] Using some frameworks for PHP serverside

[raja_s_patil]

Hi,

With lot of help from Steve on this list I could get a Flex test
application running with webORB and PHP-Firebird as serverside
many thanks to him. We also trying run it with other AMF alternatives
just for evaluation otherwise webORB is very satisfactory.
Performance is acceptable, Easy to develop and deploy.

Now we have been advised by many ppl on Firebird-PHP and On this
list also to have some PHP frameworks like Symphony, CakePHP, Zend
etc. etc.as wrappers to server side PHP.

We would like to know why we should wrap serverside with these
framework and what will be the benefits in that. According to
discussion we had it is going to add another layer in application
then we fear about performance. But since these frameworks
are there and being used extensively inspite of this issue
there must be some advantage out weighing the performance
penalty but since this is our first web application so we are
not in position to judge that. Please help us in this matter.

Similarly also suggest some good framework which is high performing,
easy to code and deploy, if at all it is beneficial to use 
such framework on server side PHP.  

Thanks and Best Regards

RE: [flexcoders] Question about ASDocs

[Gregor Kiddie]

The ASDoc compiler usually takes one pass through the code rather than
the multiple passes like the regular compiler, so if your app won't
compile in a single pass, the ASDoc can't be made.

 

Usual culprits are classes that use dispatchEvent(...) without extending
EventDispatcher but DO have Bindable tags.

What happens?  How are you sure the dates are not being set?  What happens
if you do this after setting a date:

[flexcoders] Re: Dynamic Flex Stacked Column Chart

[Tim Hoff]

And if you wanted to make it truly dynamic:

private function createChartSeries(event:Event):void
{
   var chartSeries:Array = new Array();
   var i:int;

   for (i = 0; i < chartData.length; i++)
   {
 var series:ColumnSeries = new ColumnSeries();
 series.xField = "category";
 series.yField = "val" + (i+1).toString();
 series.displayName = "Series "+ (i+1).toString();

 chartSeries.push( series );
   }

columnChart.series = chartSeries;
}

Maybe its your itemRenderer. This code works:

[flexcoders] Setting dateField.SelectedDate when component is disabled?

[Mic]

In a modal View state the dateFields are disabled but I need to populate them 
for the current record. I can stick my proc values in when they are enabled, 
but not when disabled. I tried

dtCmplxStartDate.enabled = true;
dtCmplxStartDate.selectedDate = tempStrtDt; 
dtCmplxStartDate.enabled = false;
dtCmplxEndDate.enabled = true;
dtCmplxEndDate.selectedDate = tempEndDt;
dtCmplxEndDate.enabled = false;

but no go. TIA,

[flexcoders] VIEWSTACK question.

[sailorsea21]

Hi everyone, I have a question on viewstacks.

I have my viewstack created on MXML with the main canvas also created in MXML.

something like:




At initialize I call 'getOtherCanvases' function, which adds additional 
canvases to 'myViewstack' depending on the result I receive from my DB.

My question: When I switch viewstack Index, the content of the canvas wasn't 
previously created and all the children jitter in place the first time I load 
each index. Shouldn't the "creationPolicy='all'" create all the children of the 
viewstack? 

How can I achieve this?

If I create the viewstack and main canvas in actionscript, will it solve my 
problem?

Thanks everyone. :)

[flexcoders] Re: Dynamic Flex Stacked Column Chart

[Tim Hoff]

Hey Richard,

I've found that charts don't like mxml as well as AS, when trying to
update them dynmically.  This works in AS:

private function onTwoSeries(event:Event):void
{
  var seriesA:ColumnSeries = new ColumnSeries();
  var seriesB:ColumnSeries = new ColumnSeries();
  seriesA.xField = "category";
  seriesA.yField = "val1";
  seriesA.displayName = "Series a";
  seriesB.xField = "category";
  seriesB.yField = "val2";
  seriesB.displayName = "Series b";
  columnChart.series = [seriesA,seriesB];
}

RE: [flexcoders] Working With Dynamic Datagrid

[Tracy Spratt]

Generate your columns as you are, you said that was working.  But you still
have to give the datagrid the data.  How/are you doing that?  Note, do not
use XMLList if you are binding.

Hi Tracy, 

Thanks for writing back. I did assign the XMLList to a variable and I could
assign that variable to the datagrid. 

However, since I have to create datadrigcolumns dynamically, wouldn't that
not work right? In assigning the variable to the datagrid without any other
work I would have to specify the number of columns that it fills no?

[flexcoders] Popups and accessibility (JAWS)

[KOVÁCS István]

Dear All,

I've been assigned the task of testing and fixing accessibility tasks in a Flex 
3 application. One of the problems we're having is JAWS not reading popup 
windows. The Alert control works (when the alert pops up, title, message are 
read, focus is on the default button, and the default button's label is also 
read, all without any user intervention, e.g. moving focus with TAB). However, 
popup windows created in other ways (e.g. the sample at 
http://livedocs.adobe.com/flex/3/langref/mx/containers/TitleWindow.html) do 
not: the popup is shown, but JAWS does not read anything.

Are we doing something wrong, is there some special setting that we need (or 
perhaps JAWS treats Alert in a special way)? We have a popup window component 
that handles user confirmations, having a configurable number of buttons, a 
title and a text message. I've tried setting focus (setFocus() and 
drawFocus(true)) on the window or the Label component used to display the 
message, and it's OK on the screen but JAWS does not read anything.

Thanks in advance,
István

[flexcoders] module loading and progress load slow?

[Jason B]

loading modules 

I've been rearranging my application to use modules to reduce load time and 
prepare it to handle later larger development etc...
All is well I've got it loading modules and such and learned a lot over the 
past few days. 

I have several modules that have large images it uses with source= and some 
other swf's it loadsI prefer not to allow caching since these items change 
a lot.

On a localhost connection (dev) It can take 10 seconds to load the module etc.
At first I thought it was needing a preloading technique that adobe offers so i 
tried that to load while the app loaded etc.. no go

then i tried to see if i could add a progress bar on top of the module loading 
so the user is at least informed but to my dismay it loads too fast for the 
progress bar to show up

heres the size of the swif being loaded
364K 2009-04-23 13:54 nutrition.swf

the images and other swfs that load into this module are about 1-2 megs total. 

If i avoid using modules it loads on localhost almost instantly :(

I have a feeling the source = for images and swf loading is whats dragging it 
to load fast.


What options do i have for either preloading quicker for this module?
Is it possible that my custom component is causing this performance issue?

Use the profiler to see if you have a memory leak somewhere. Sounds

[flexcoders] Re: DataGrid combobox erasing items from it's list

[Tim Hoff]

Hi,

Your code looks fine.  But, I believe that you need to handle the
itemEditEnd event, for the DataGrid:



  Something like this:

private function onItemEditEnd(event:DataGridEvent):void
{
  // Check the reason for the event.
  if (event.reason == DataGridEventReason.CANCELLED)
  {
   // Do not update cell.
   return;
  }

  // Get the new data value from the editor.
  var newData:String =
ComboBox(event.currentTarget.itemEditorInstance).selectedLabel;

  // Determine if the new value is an empty String.
  if(newData == "")
  {
   // Prevent the user from removing focus,   and leave the cell
editor open.
   event.preventDefault();
   return;
  }
}

[flexcoders] Re: Flash/FLex gravity

[flexaustin]

I have the book now. I am trying to make it work and I am almost there, but the 
sprite is only glides correctly when thrown if I drag from top right to lower 
left or lower left to top right.

If I throw it directly to the right it moves up and if I throw it to directly 
to the left it goes down. If I throw it up it goes to the right. And if I throw 
it down it moves to the left.

Here is the code (_object is the sprite being throw):

if(_drag == true){

var diffx:Number = initX - mx;
var diffy:Number = initY - my; 

var speed:Number = 12;
var angle:Number = Math.atan2( diffx, diffy );
//var radians:Number = deg2rad(angle);
var xVel:Number = Math.cos(angle) * speed;
var yVel:Number = Math.sin(angle) * speed;

function deg2rad(deg:Number):Number {
return deg * (Math.PI/180);
}

function onLoop(evt:Event):void {
_object.x += xVel;
_object.y += yVel;
 
xVel *= 0.9;
yVel *= 0.9;

if (xVel < 0.05 && yVel < 0.05) {
_drag = false;
 
_stage.removeEventListener(Event.ENTER_FRAME, onLoop, false);
}
 
}


_stage.addEventListener(Event.ENTER_FRAME, onLoop, 
false, 0, true);
//get the velocity and direction and make it go 
another 100 pixels or more
}

So the scenario is:

 1.  user clicks cell, CB editor appears
 2.  user clicks away somewhere, without selecting anything
 3.  ComboBox closes
 4.  an empty string is stored in the dataProvider

Yes?  Is the change event and handler firing in this case?

If so, then I think you need to make the renderer set the ComboBox's 
selectedIndex to display the current value.  Thus however the change event was 
caused, the correct value would be put back in the property.

I think you would want this behavior anyway.  Note you can't directly set 
selectedItem, but must loop over the dataProvider comparing property values, 
then using the loop index to set the selectedIndex.

I have a DataGrid that is linked to an array of custom data objects which I 
call a seriesList. You are supposed to be able to choose the name of each 
series via a combobox in the datagrid. It works fine except when the user 
selects the combobox and then clicks somewhere else in the interface, which 
closes the combobox and erases whichever item is previously selected!

[flexcoders] Imported SWC files don't display correctly

[fumeng5]

Hi,

I am importing 4 swc files; a left arrow, right arrow, up arrow, and down 
arrow. 

The problem is that the right arrow displays as the left, and the down as the 
up arrow. 

When I preview the SWC files in their corresponding SWF files they look right. 

Has anyone else experienced problems displaying SWC files correctly? 

Thanks for any helpful tips!

It does sound like you are describing the bug
where the focus manager holds onto the reference of the combo box and
stops the module unloading...

If you lose the combobox focus, does the module
unload?

Thanks Pedro,

 

I've seen what your describing in the docs - I'm
looking at this via the profiler which is giving me feedback as to
number of live instances, etc. 

 

Here's what I'm basing my statements on:.

 

1) I start up my app, which loads modules at
runtime based upon user choice from a menu.

 

2) Module exectues Cairngorm
Event/Command/Delegate to get array to populate a combo box. I'm passing
a reference to the module's model in my Cairngorm event and the model is
updated upon completion of the Command.

 

3) Combobox is bound (via MXML) to the model.

 

4) If I don't interact with the combobox, I can
then logout and unload the module successfully. The profiler tells me
there was previously 1 instance of the module and now there are zero
instances.

 

5) If I make the combobox active (by interacting
with it in any way), and then logout, the module remains in memory, with
the profiler reporting one instance instead of zero.

 

6) If I then login again, the Profiler reports 2
active instances of the module.  Note that any model objects are
duplicated as well. Fo

RE: [flexcoders] DataGrid combobox erasing items from it's list

[Tracy Spratt]

So the scenario is:

1.  user clicks cell, CB editor appears
2.  user clicks away somewhere, without selecting anything
3.  ComboBox closes
4.  an empty string is stored in the dataProvider

 

Yes?  Is the change event and handler firing in this case?

 

If so, then I think you need to make the renderer set the ComboBox's
selectedIndex to display the current value.  Thus however the change event
was caused, the correct value would be put back in the property.

 

I think you would want this behavior anyway.  Note you can't directly set
selectedItem, but must loop over the dataProvider comparing property values,
then using the loop index to set the selectedIndex.

selects the combobox and then clicks somewhere else in the interface, which

[flexcoders] 360|Whisperings online Technical articles, looking for authors.

[John Wilker]

For those that don't know me, I'm John Wilker, co-founder of 360|Conferences
(360|Flex, and 360|iDev). Tom Ortega and I have created a new venture to go
along with our community oriented conferences. 360|Whisperings (
http://www.360whisperings.com). For those of you who own Amazon Kindles you
know that Whispernet is the delivery medium for purchased content.

We've created a site where people can come and browse the available content
and instead of subscribing for all you can eat, simply purchase the articles
that they want. Subscriptions are great, but you have to get your money's
worth. We're looking to go more the iTunes route, for a buck or two, get the
same quality article you would from a pay site or journal, knowing it's
quality content, and not have to pay for the content you don't want or need.

We're not just going to be limited to the Kindle (and the iPhone/iTouch
technically) but that's a good turn key place to start. Our goal is to offer
content in as many formats as we can (PDF, ePub, Mobi, PRC, etc) so that
everyone can get access. We'll take care of editing and marketing the
content and reporting on sales. The split is 60/40 us, in exchange for the
stuff I just mentioned. Our conference sites will link to and highlight
content as well as the primary site itself. I know it seems like small
change, and it is to start, but the more articles we get, the more momentum
this offering builds.

We've got a few folks signed on right now, coming up with article ideas.
We're hoping to get a few more folks for the "official" launch so that we've
got a good library set up and ready for folks. Why subscribe to sites and
journals, and have no idea how much value you'll get from the content? Just
pay for what you want. We're looking for technical content on any topic; CF,
FLex, Flash, AIR, Java, etc.

When this XML gets returned to Flex I need to throw it into a Datagrid for

[flexcoders] Working With Dynamic Datagrid

[blkmajk111]

Hey All,

I'm having an issue that I was hoping someone can help me out with.

I need to populate a datagrid based on XML being returned to Flex. The 
structure of the XML is as follows: 

"
 
  
  
  
 
 
  
  
 
"

When this XML gets returned to Flex I need to throw it into a Datagrid for 
diaplay. The catch is there can be any number of columns in the datagrid 
becasue the assignments can be of different quantities.

Here is the code that I am using to make the grid:

 "private function getGradebookSectionDb(event:ResultEvent):void{
  var gradebookBySection:XMLList = event.result.lab;

  var cols:Array=new Array;

  for (var i:int=0;i

Thanks Mark, I see my version of Flexbuilder is 3.0.1, not 3.0.2!  I'll try 
upgrading!

Everyone else, thanks for responding - a lot of you have been recommending I 
understand there are two different versions of the Flash player - the regular 
release and the debug version.  I'm not sure how I gave the impression I didn't 
understand that, even from the beginning, I clearly do - especially if you read 
my original post.  Funny, because I titled this thread, "Flash player 10 
Debug...".  Maybe when Alex called them "binaries" instead of players and I was 
confused by that and asked a question about what he meant, that threw some of 
you off. Sorry! ;)  It was just because never heard of the Flash players being 
called a "binaries" before - so I didn't know if he was talking about something 
else entirely. Also, as I stated, I have run the uinstaller and then the 
installer for the DEBUG version of the player without luck, as I mentioned.  

So sorry for any confusion, didn't mean to waste your time responding to the 
wrong question.  My problem is that after uninstalling FP10 and re-installing 
FP10 DEBUG version, FB3 still does not recognize it.  

I'm going to take Mark's advice and upgrade FB3 and see if that works.  Thanks 
everyone for your help!

RE: [flexcoders] Re: HTTPService mistery

[Tracy Spratt]

What is the result format of the HTTPService call?  The default "object"
causes the flex client to process the incoming data into a tree of dynamic
objects.  The speed of this process would be subject to the local cpu.  You
could set resultFormat to e4x, and re-run the benchmarks.

While it seems to me I am missing something obvious I am pretty sertant it
is somewhere in the send command. I have traced an execution to the point
that for a low end box it takes about 5 sec. between a send command and an
HTTPService callback function call. I have timed my server and it does not
take time at all. I timed the server for both my development computer and a
low level box. Server time is exactly the same. (what else whould one
expect?) But time it tales for an execution to get into a callback function
is very different. So, I am assuming that it takes some time for a low end
box to send a data request to the server.

RE: [flexcoders] Unloading Modules - Binding is the Enemy?

[Battershall, Jeff]

Gregor,
 
Very interesting indeed.  If I login, load the module, interact with the
combobox, logout, the instance remains in the profiler.  However if I do
all that and THEN load another module and logout, the number of
instances of the first module goes to zero.  These modules are being
loaded into a ViewStack, BTW.  
 
Is this the FocusManager bug you described?  Is there a workaround?
 
I'd be thrilled to discover that Binding was not the culprit here.
 
Jeff

It does sound like you are describing the bug where the focus
manager holds onto the reference of the combo box and stops the module
unloading...

If you lose the combobox focus, does the module unload?

Thanks Pedro,

 

I've seen what your describing in the docs - I'm looking at this
via the profiler which is giving me feedback as to number of live
instances, etc. 

 

Here's what I'm basing my statements on:.

 

1) I start up my app, which loads modules at runtime based upon
user choice from a menu.

 

2) Module exectues Cairngorm Event/Command/Delegate to get array
to populate a combo box. I'm passing a reference to the module's model
in my Cairngorm event and the model is updated upon completion of the
Command.

 

3) Combobox is bound (via MXML) to the model.

 

4) If I don't interact with the combobox, I can then logout and
unload the module successfully. The profiler tells me there was
previously 1 instance of the module and now there are zero instances.

 

5) If I make the combobox active (by interacting with it in any
way), and then logout, the module remains in memory, with the profiler
reporting one instance instead of zero.

 

6) If I then login again, the Profiler reports 2 active
instances of the module.  Note that any model objects are duplicated as
well. For example, if my list of suppliers (used to popuate my combobox)
(a strongly typed AS class) was previously 64, the profiler now reports
there are 128 instances.  

 

There's my behavior.  When my UI object (in this case ComboBox),
becomes active, the binding becomes active and then the module will not
unload, even if I set the modules model to null before attempting to
unload.  It would appear that I need to invalidate all outstanding
bindings to any data object before the module will fully unload.  This
would seem to indicate that MXML binding (via curly braces) isn't going
to allow this.

Re: [flexcoders] e4x challenge

[Daniel Freiman]

If you want to select them, then:

XMLList list = xml.descendants().(@type = "file)

otherwise, i'd still get that list and then loop through it and delete each
by doing (exact code might need some cleaning):

for (each item:XML in list) {
   delete item.parent()[item.childIndex()];
}

[flexcoders] DataGrid combobox erasing items from it's list

[netdeep]

I have a DataGrid that is linked to an array of custom data objects which I 
call a seriesList.  You are supposed to be able to choose the name of each 
series via a combobox in the datagrid.  It works fine except when the user 
selects the combobox and then clicks somewhere else in the interface, which 
closes the combobox and erases whichever item is previously selected!

RE: [flexcoders] Unloading Modules - Binding is the Enemy?

[Gregor Kiddie]

It does sound like you are describing the bug where the focus manager
holds onto the reference of the combo box and stops the module
unloading...

If you lose the combobox focus, does the module unload?

Thanks Pedro,

 

I've seen what your describing in the docs - I'm looking at this via the
profiler which is giving me feedback as to number of live instances,
etc. 

 

Here's what I'm basing my statements on:.

 

1) I start up my app, which loads modules at runtime based upon user
choice from a menu.

 

2) Module exectues Cairngorm Event/Command/Delegate to get array to
populate a combo box. I'm passing a reference to the module's model in
my Cairngorm event and the model is updated upon completion of the
Command.

 

3) Combobox is bound (via MXML) to the model.

 

4) If I don't interact with the combobox, I can then logout and unload
the module successfully. The profiler tells me there was previously 1
instance of the module and now there are zero instances.

 

5) If I make the combobox active (by interacting with it in any way),
and then logout, the module remains in memory, with the profiler
reporting one instance instead of zero.

 

6) If I then login again, the Profiler reports 2 active instances of the
module.  Note that any model objects are duplicated as well. For
example, if my list of suppliers (used to popuate my combobox) (a
strongly typed AS class) was previously 64, the profiler now reports
there are 128 instances.  

 

There's my behavior.  When my UI object (in this case ComboBox), becomes
active, the binding becomes active and then the module will not unload,
even if I set the modules model to null before attempting to unload.  It
would appear that I need to invalidate all outstanding bindings to any
data object before the module will fully unload.  This would seem to
indicate that MXML binding (via curly braces) isn't going to allow this.

Jeff,

Calling GC programmatically does not mean that it will be
executed.

Like java, the GC in flex is not under programmer's control. You
may call it, but it won't be executed if it is not necessary.

"Clicking the Run Garbage Collector button does not guarantee
that all objects that are eligible for garbage collection will be
garbage collected. Garbage collection is typically triggered by the
allocation of memory for new resources."

Hi Jeff,

The fact that you unload a module does not mean
that it will be garbage collected(the memory won't be released as soon
as you unload your module). Unload the module makes it available for
garbage collection.

As far as I know, the module 'garbage' will be
collected by the GC when necessary, so don't think that unload a module
means free memory in the exactly same moment.

I'm supposing that you are testing in your
development machine(probably a good machine) so I suggest you to test it
in a limited machine to see if this memory is released when it is
necessary , that is the point.

Re: [flexcoders] chart axis renderers inside data area

[Sam Lai]

Thinking up the top of my head here -

Maybe you could inherit and trick the axis renderer into thinking it
is rendering the axis on top of the chart, and therefore the labels
are above the stroke and ticks (instead of below)?

That's what you want right?

[flexcoders] Unloading Modules - Binding is the Enemy?

[Battershall, Jeff]

In testing via the Profiler, binding UI objects in a module to a model
(even if local to the module) appears to be causing a module's failure
to unload. This happens as soon as the UI component becomes active. In
fact, even if the source object (data provider) is set to null, the
binding persists and will prevent a module from unloading. Does this
issue have to be such a PITA? It appears that using curly braces for
binding in MXML can create Modules that won't unload. 

In FP 10, the Loader class has the new unloadAndStop() method. Would be
extremely handy to have something similar for Modules. Basically you
want to remove all listeners to a model and then unload the module.

Maciek, pushing axisrenderer to annotationElements array doesnt seem to

Sam, setting negative gutters works (any negative gutter does the same) but

Make sure your server code keeps track of the overall list of rooms, and 
provides a method you can all via RemoteObject to provide that list.

Again, just make a RemoteObject call when a user logs on.

[flexcoders] Two way binding in Flex 4

[Gregor Kiddie]

Morning all (well it is here ;) ),

One for the Adobe guys I think, though anyone who's dug around in the
Flex 4 SDK can chip in!

 

Flex 4's two way binding... does it create an breakable reference in the
same way as MXML binding does just now? I'm trying to judge its
usefulness, and Ted Patrick's comments on his blog have totally confused
me!

http://www.onflex.org/ted/2008/09/useweakreferencesboolean-false.php#com
ment-6262590827069335129

Basically, will we be making the already bad memory leak problem worse
by using the two way binding?

[flexcoders] "Blank Screen" issue with application preloaders

[b_alen]

I get a blank screen for more than 10 seconds for the app that's about 700k in 
size. Only then the preloader appears and starts from somewhere around 70%. 

In the Flash days, this was easily solved by having one small SWF with 
preloader that would load the main SWF in empty movie clip. Is something like 
this possible in Flex? 

I did a small experiment with loading the Flex app into Flash SWF, but then the 
sizing and alignments were lost. I also tried loading a Flex app into a smaller 
Flex app, but still there was a blank screen for quite a while.

It's a huge usability issue knowing that users leave after 8 seconds, which is 
actualy true looking at google analytics reports.

I've checked numerous blogs about custom preloaders but only found that all of 
them have the same issue. 

These are all the apps and samples with the same issue:

Does it exist?

Thanks for your reply. OK. Then. 
I may write a new small interface
program to extract and display data 
from server rather than a full 
application program with edit 

May I ask ... Any suggestion on 
development tools on mobile ? Flash 
CS4 Flash Lite or Flex Builder ?

Re: [flexcoders] Migrate Flex to Flash Lite

[Rick Winscot]

What you are asking is a huge task... even the prospect of using classes in
Flash Lite will cause huge performance issues not to mention the fact that
you will have to translate/port any Flex framework bits you use in your Flex
app to Flash Lite. This would not be a trivial task.

I wouldn¹t recommend trying to create a Flash Lite product that maintains
parity with a Flex app without serious contemplation on what your users
Œactually¹ need and not what they Œthink¹ they need.

Subject: [flexcoders] List sizing - height="100%"





I am trying, in MXML, to size a list to 100% of its container, but when I do, 
it only shows 2 rows. It is using a custom item renderer. I tried setting a 
rowHeight as well but still doesn't size right. I also set an explicitHeight in 
the item renderer itself. Nothing.

In a fixed size layout, i can set the rowcount but I want it to be fluid in 
case the user resizes the window.

Anyone know why a list wouldn't size by percent to fill a parent container?
