Re: [flexcoders] Re: Soap XML doc passed to SoapDecoder.as
decoder would be a SOAPDecoder, yeah. I think decode() is defined in IXMLDecoder or some such, and implemented in XMLDecoder. SOAPDecoder just provides the SOAP-specific decoding stuff, on top of a generic XSD-based xml - object decoder provided by XMLDecoder. I haven't poked around inside these much, but I've been up to my neck in the encoding side of the same activity recently fixing a bug in the way our Arrays were getting encoded by Flex - and I imagine it's very similar, just the reverse. -J On Thu, May 8, 2008 at 3:50 PM, securenetfreedom [EMAIL PROTECTED] wrote: In your example, would 'decoder' be of type SOAPDecoder?

Re: [flexcoders] Re: need help deciphering error message
This would imply that courseCat is null, or perhaps if the exception is
actually being thrown inside the SDK code, it could have a null
dataProvider? I'm not sure about that second possibility though.

Subject: [flexcoders] need help deciphering error message
Hello,
I get the error message below when I am running my application,
however it runs fine when I click continue. There isn't an error when
I compile in Flex builder. I checked the function that references the
object and they are all defined and the objects exist.
The only thing I can think of is that the object that is referenced in
the function isn't displayed on the application startup (its on the
second canvas of a view stack) so it throws this error, however when I
move the call to the function to execute only when the second canvas
is displayed I still get the error.
I'm sure its a common error that many newbies must hit. I appreciate
any clues to look for in the code.
Thanks,

I checked and the combobox with id courseCat is there, does it make a
difference that it is on the second canvas of a viewstack container?
I can see it throwing an error if it's not drawn till needed, but I
thought that viewstack container just control visibility and that all
it's children are actually created just not visible.
Is this assumption wrong?

I have a flex application the uses binary sockets. It does not work with the new security update. To fix this I have implemented a server that listens on port 843. This works. I have just one problem. I am currently using the wildcard * in the allow-access-from domain attribute. Like this: allow-access-from domain=* to-ports=123,456-458 / I do not want to have to do this. I just want to specify that if the swf was served from the server itself, then it can have access. Is there a way to do this with out actually hard coding that domain? I tried localhost, but that does not work. Is there some key word that will specify this behavior? Thanks, Chris

[flexcoders] reading serial port with AIR / or pipe in linux with AIR application

From internet searchs, people suggest to write a C code to read data and export to a file from which Flex will read, but considering 5ms precision will not be possible in this way. I can do this with pipes of linux, but is there a way to pipe an AIR application with an executable in linux ? Any help/suggestion is welcome, thanks yigit

[flexcoders] Flex Base Singleton class based on introspection
Currently, ActionScript doesn't have support for private class
constructors, thus any class's constructor can be accessed. But
there are times when you'll want your class to be instantiated just
one time, meaning its constructor called just one time.
Some authors have proposed to solve this problem by defining a
file-local accessible class in the singleton definition file required as
argument of the singleton class constructor:
package
{
public class ASingletonClass
{
private static var instance:ASingletonClass;
public static function getInstance():ASingletonClass
{
if( instance == null )
{
instance = new ASingletonClass( new SingletonEnforcer()
);
}
return instance;
}
public function ASingletonClass( enforcer:SingletonEnforcer ){}
}
}
class SingletonEnforcer {}
There are two problems with this implementation:
1. it is still possible to pass null as constructor argument, so the
ASingletonClass constructor should at least throw an exception if the
argument is null2. every specific singleton class must define this
code snipplet over and over again
Ideally all singleton functionlity should be put into a base Singleton
class which should be derived as:
public class TestManager extends Singleton
{
// private member instance and getInstance method are defined in base
class
public function test():void {
}
}
The test function can be accessed as:
Singleton.getInstance(TestManager).test();
Or:
var testManager:TestManager = Singleton.getInstance(TestManager) as
TestManager;
testManager.test();
The following code shows a way to implement this base Singleton class.
It used introspection to create and store all singleton instances
(except an instance of the base class itself) into a dictionnary using
objects of type Class as key.
package common.util.singleton
{
import flash.utils.Dictionary;
import flash.utils.getDefinitionByName;
import flash.utils.getQualifiedClassName;
public class Singleton
{
private static var instanceDict:Dictionary = new Dictionary();
/**
* Conceptually private constructor
*
*/
public function Singleton()
{
var className:String = getQualifiedClassName(this);
var clazz:Class = getDefinitionByName(className) as Class;
if(clazz==Singleton) {
throw(Singleton is a base class that cannot be
instantiated);
}
var instance:Object = instanceDict[clazz];
if(instance!=null) {
throw(Classes extending Singleton can only be instantiated
once by the getInstance method);
} else {
instanceDict[clazz]=this;
}
}
/**
* Get the single instance
* @return the single instance
*
*/
public static function getInstance(clazz:Class):Object
{
var instance:Object = instanceDict[clazz];
if(instance==null) {
//create a new instance of class clazz
instance = Object(new clazz());
//check that the newly created instance is a Singleton
var singleton:Singleton = instance as Singleton;
if(singleton==null) {
throw(getInstance can only be called for Classes
extending Singleton);
}
}
return instance;
}
}
}
Of course throwing an exception at runtime is less nice than making the
constructor completely inacessible. But as said earlier, the
SingetonEnforcer class doesn't prevent null being passed to the
singleton constructor and thus also needs runtime checking.
The most important thing, if you need to implement several singleton
classes, is to have a consistent and coherent protection code written on
a single place.

It turns out Firefox 3pre nightly is to blame. It broke Flash (I think). I have been using Minefield versions, and I guess the particular nightly build I was using broke Flash.

Re: [flexcoders] How to build Modular Application
Hi Indra, If your working with Flex builder, right click your project-properties-Flex Modules and add the path you your module mxml file. Once completed your module will be compiled to a .swf file when built. The project I am working on has build the app as a set of modules, each module is loaded by a core framework (ModuleShell). I modeled the puremvc multicore modularity demo application, making changes to load modules instead adding UIComponents to a container. Check it out and you should be able to use it as a base to extend/modify for your needs http://trac.puremvc.org/Demo_AS3_MultiCore_Flex_Modularity. Even if you don't use the puremvc framework you can still use the code as an example impl.

[flexcoders] Re: need help deciphering error message
This is a wrong assumption. Only the first viewStack child will be
instantiated initially; unless you use the evil creationPolicy=all
setting. If you run your program in debug mode, it should break on the
exact line that is causing the error; to help you pinpoint the problem.
Since your second viewStack contains the comboBox, you might be trying
to explicitly set the selectedIndex of a control that doesn't exist yet:
courseCat.selectedIndex = 0;
The comboBox will not be instantialted until you change the viewStack's
selectedIndex. You can get around this by using a bound variable for
the comboBox's selectedIndex.
mx:ComboBox selectedIndex={ myComboBoxSelectedIndex }/
In the script:
[Bindable]
private var myComboBoxSelectedIndex : int = -1;
// use public if necessary - can also set the default index to 0 here;
if desired.
in the resultHandler:
//courseCat.selectedIndex = 0;
myComboBoxSelectedIndex = 0;

Hello,
I get the error message below when I am running my application,
however it runs fine when I click continue. There isn't an error
when
I compile in Flex builder. I checked the function that
references the
object and they are all defined and the objects exist.
The only thing I can think of is that the object that is
referenced in
the function isn't displayed on the application startup (its on
the
second canvas of a view stack) so it throws this error, however
when I
move the call to the function to execute only when the second
canvas
is displayed I still get the error.
I'm sure its a common error that many newbies must hit. I
appreciate
any clues to look for in the code.
Thanks,
Hoyt

Re: [flexcoders] What happens to objects when you change state?
Cepends on what your states are defined to do, but sounds like you're adding and removing children on the state change, which is pretty common.

[flexcoders] Re: Flex Item Renderer using popup to edit datagrid - How to refresh datagrid?
Hi Mary, Typically, when you make an update to a DB, you will want to refresh the dataGrid's dataProvider with the updated data from the DB. This usually means either returning an updated object in the result of an update service call, or making an additional call to get the data from the DB; after the DB object has been successfully updated. If you use binding for the dataGrid's dataProvider, you won't have to communicate with the dataGrid at all. Just refresh the dataProvider collection and Flex will handle the rest for you. -TH --- In flexcoders@yahoogroups.com, web2mmac [EMAIL PROTECTED] wrote: Hi, I have a Flex app that has a datagrid with an Item Renderer.

[flexcoders] Re: FlexPrintJob: print image AND text [SOLVED]
Thanks for your response! I made some breakthroughs this morning...we'll see if it is a fluke, or if my changes really fix the problem for me. ;) Essentially, we have been using our own FlexPrintJob class so that we can better control portrait/landscape settings for our needs. The problems that I have been having hav existed in an older version of the FlexPrintJob code that we had essentially copied because it did not expose enough properties and methods to make it possible to extend it properly. I think that the new version of FlexPrintJob has the code that really fixed the previously mentioned bug, not the Flash Player. The differences are the addition of calls to prepareForPrinting and finishPrinting methods, which call the prepare and finish methods on the object that is being printed and it's parent chain. This code seems to cause the objects on my page to be the correct sizes and assure that they are ready for printing when they are added to the print job. --- In flexcoders@yahoogroups.com, Frederico Garcia [EMAIL PROTECTED] wrote: Hi, I forgot posting that I'd found the reason to my problems.

movieclip instance within the swf file.
mapa_ins.addEventListener(MouseEvent.CLICK,
function
(e:MouseEvent):void{gFlexProvincia = mapa_ins.gProvincia});
}

I have access to the swf methods and variables from flex, but as I've
said, not the other way round.
I've tryed mapa_ins.parent and the like, but no way

I'm also not sure why this happens, but if you change the code in

works.

[flexcoders] Container ScrollBar Click vs Container Click
Is there an effective way to determine a click on a scroll bar versus a click on the container? mx:Canvas height=200 width=200 verticalScrollPolicy=auto click=containerClick()/ I only want the click event to fire for the container if the click was NOT on the scrollBar, if the scrollBar exists. I know that I can check the container mouseX value and generally tell whether or not the scrollBar was clicked (assuming the contents of the container require a scrollBar), but that isn't fool proof, depending on whether or not there is a scrollBar. The FlashPlayer certainly can tell the difference, since it knows when to scroll and when not to scroll, based on where the user clicks. Seems the container class controls should have a couple more event triggers: verticalScrollClick and horizontalScrollClick

I made some breakthroughs this morning...we'll see if it is a fluke, or if my changes really fix the problem for me. ;) Essentially, we have been using our own FlexPrintJob class so that we can better control portrait/landscape settings for our needs. The problems that I have been having hav existed in an older version of the FlexPrintJob code that we had essentially copied because it did not expose enough properties and methods to make it possible to extend it properly. I think that the new version of FlexPrintJob has the code that really fixed the previously mentioned bug, not the Flash Player. The differences are the addition of calls to prepareForPrinting and finishPrinting methods, which call the prepare and finish methods on the object that is being printed and it's parent chain.

Subject: [flexcoders] flash - flex communication
Hi all,
my first posting here, glad to meet you.
I'd appreciate any hint on the following problem I've got. I have an
embedded swf into a flex app. From the embedded swf, I want to make
calls to the flex container, but until now, any atempt has been useless.
my swf is instantiated this way
mx:SWFLoader source=assets/flash/mapa_galicia.swf id=mapaSWF
complete=onMapaSWFCompleted(event); /
mx:Script
![CDATA[
private var loadedSWFMainTimeline:*;
private var mapa_ins:MovieClip;
private function onMapaSWFCompleted(event:Event):void
{
loadedSWFMainTimeline = mapaSWF.content;
mapa_ins = loadedSWFMainTimeline.mapa_ins;
// mapa_ins is a
movieclip instance within the swf file.
mapa_ins.addEventListener(MouseEvent.CLICK,
function
(e:MouseEvent):void{gFlexProvincia = mapa_ins.gProvincia});
}
]]
/mx:Script
I have access to the swf methods and variables from flex, but as I've
said, not the other way round.
I've tryed mapa_ins.parent and the like, but no way
any help?

RES: [flexcoders] value object binding problem
You MUST import the classes used into the ArrayCollection.
Or, you may use the ArrayElementType, for the auto-import at the
compiler time.
public class LookupData {
[ArrayElementType(package.ClassA)]
public var attributeA:ArrayCollection;
[ArrayElementType(package.ClassB)]
public var attributeB:ArrayCollection;

Re: [flexcoders] Printing flex datagrid to PDF.
If you're not dependent on Coldfusion to build the PDF, check out AlivePDF, which lets you build a PDF client-side. In a browser-based app it requires you to install a server-side script to bounce the bytes back to the browser. Here's an example using it: http://www.sinergy-networks.com/images/stories/portadas-klitekture/klk012/cover_generator/ On Thu, May 8, 2008 at 11:49 AM, shaf ram [EMAIL PROTECTED] wrote: Have a look at ImageSnapshot new to Flex 3.

RES: RES: [flexcoders] value object binding problem
Hey ibo,
A map can not be converted to an ArrayCollection (
http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.

A map will be converted to an Generic Object, and the key will be a

public class LookupData {

public var attributeA:ArrayCollection;
[ArrayElementType(package.ClassB)]
public var attributeB:ArrayCollection;
public var attribute1:Object;
public var attribute2:Object;
public var attribute3:Object;
}
You may access those properties with attribute1.key1,
attribute1.key2, attribute1.anotherKey, ...
And in that case, remember to import the value classes.

[flexcoders] Vector printing and transparency - consistency problem
OK, I've got most of my vector printing working and looking really nice except for transparency. I sure wish that I could print images with transparency while still doing Vector printing, but understand that there is currently no way to do this right now. Will this be offered in the future? The problem that I am still having is consistency. Pretend that I have a page with 5 images on it, each one has some transparency in it. If I print this same page over and over I will get different results each time. Sometimes the page will only print images #1, #3, and #4. The next time it might only print images #2, #3, and #5. The next time it might print all 5 images. The results seem to be random. The images have all been pre-loaded before printing and it doesn't seem to be a loading problem. The problem ONLY exists for images with transparency in them. Any picture that doesn't have transparency in it will print correctly every time without fail. Does anyone have any ideas what is happening? I sure would like some consistency so that I will know what customers can expect. Thanks!
RE: [flexcoders] Re: Wierd behaviour with selectedItem on Datagrid
When you apply a sort to a collection we use the collection to find
selectedItems, hoping that is faster than scanning the collection
ourselves. In your case you do not have unique values in the sort
column so selectedItem finds an arbitrary match and things go downhill
from there. That's probably worth filing a bug for.
I was able to get your example to work by using selectedIndex like this:
private function cc() : void{
array = new ArrayCollection([
{count : 1207662300, wp : A},
{count : 1207662300, wp : B},
{count : 1207662300, wp : C},
{count : 1207662300, wp : D},
{count : 1207662300, wp : E}
]);
var sorting : Sort = new Sort();
var sortByCount : SortField = new
SortField(count,false,true,true);
sorting.fields = [sortByCount];
this.array.sort = sorting;
this.array.refresh();
dg.selectedIndex = 3;

Re: [flexcoders] Vector printing and transparency - consistency problem
Using transparency causes some sort of mode switch inside Flash. It used to be one of the tricks you could do in order to get around a bug that was in the player for years where movement over the top of a bitmap would cause parts of it to shift around by a few pixels. So my long-winded point is that it's probably a fundamental thing. BTW does that bug still exist?

[flexcoders] Changes in dot releases of Flash Player 9
I'm running into issues with an AS3 project on versions of Flash Player 9 prior to 9.0.115. Does anyone know were I can find a change log or a bug list of Flash Player 9 dot releases?
[flexcoders] Re: Modules the way to go?
The crashing of the explorer is due to the amount of load in memory.
It's not a Flex Error in the white box at the top left form.
We load the modules this way:
public function createModule ( url : String ) : void
{
var panel : Panel = new Panel();
var module : IModuleInfo = ModuleManager.getModule( url
);
module.addEventListener( ModuleEvent.READY,
function moduleReadyHandler ( event :
ModuleEvent ) : void
{
var view : UIComponent =
module.factory.create() as UIComponent;
view.x = 0;
view.y = 0;
view.percentHeight = 100;
view.percentWidth = 100;
panel.addChild( view );
module.removeEventListener(
ModuleEvent.READY, moduleReadyHandler );
}
);
module.load ( );
}
and the unload is done this way:
public function closeModule ( url : String ) : void
{
var module : IModuleInfo = ModuleManager.getModule( url
);
module.unload();
}
It's simple... basic... Am I missing something?

No they shouldn't. We run an application with similar amounts of
modules
(though bigger in size) without too many problems. There is
anecdotal

[flexcoders] Help with Module strategy
I'd appreciate some input on my module strategy. I'm working on a charting application with a requirement that individual charts be embeddable as widgets on arbitrary pages. I already have the bulk of the code in libraries, so have some freedom to explore different packaging. I had originally thought that it would make sense to create a module for each chart, and two separate hosts, one main application and one widget host. I understand that I would have to use RSLs and framework caching to keep the module size down. Frankly, I'm a little wary of that given the time constraints, and also because it depends on the later player. Another approach was to just build a different application SWF for each widget and modularize only when the main app becomes too large. Now I am considering the following: - the host is a single SWF with two states (widget and full). It loads either one, or several modules based on runtime config - the charts are in modules, optimized for the single host - the single app and multiple modules are in one project, so I can optimize for that app in Flexbuilder (though we do have continuous integration set up too) The only downside I can think of is that if the full state of the app has a lot of code besides the module code, the size of the widget download will be larger than it needs to be. On the other hand, it would allow the full app to be embedded as a widget, since the UX would be determined at runtime. And I suppose the full host state could itself be modularized. Comments? Thanks in advance.

unloading the module does not guarantee it will cleaned up by Garbage
Collection.
You can use the Profiler to assist you see what has be collected by GC
and what hasn't.

This is a wrong assumption. Only the first viewStack child will be

Since your second viewStack contains the comboBox, you might be trying
to explicitly set the selectedIndex of a control that doesn't exist yet:
courseCat.selectedIndex = 0;
The comboBox will not be instantialted until you change the viewStack's
selectedIndex. You can get around this by using a bound variable for
the comboBox's selectedIndex.
mx:ComboBox selectedIndex={ myComboBoxSelectedIndex }/
In the script:
[Bindable]
private var myComboBoxSelectedIndex : int = -1;
// use public if necessary - can also set the default index to 0 here;

Hello,
I get the error message below when I am running my application,
however it runs fine when I click continue. There isn't an error
when
I compile in Flex builder. I checked the function that
references the
object and they are all defined and the objects exist.
The only thing I can think of is that the object that is
referenced in
the function isn't displayed on the application startup (its on
the
second canvas of a view stack) so it throws this error, however
when I
move the call to the function to execute only when the second
canvas
is displayed I still get the error.
I'm sure its a common error that many newbies must hit. I
appreciate
any clues to look for in the code.
Thanks,
Hoyt

[flexcoders] ComboBox and ViewStack inside a Repeater
Hi all, I have a combobox and a viewstack inside a repeater. How can I get to change the the viewstack child containers by the changing values of the combobox, during runtime. are they any reference examples that I cud take a look at. Thank you, Kal.
Re: [flexcoders] ComboBox and ViewStack inside a Repeater
viewstack selectedIndex={ combobox.selectedItem.magicNumber }/ ?
On another note, an entire viewstack inside a repeater seems like a recipe
for memory usage to me. Are you sure you couldn't at least use a list? It
instantiates less components and scrolls by changing renderer.data

If you are creating widgets or gizmos with Flex/Flash. I don't think you will ever hit the 'pain threshold.'

Additionally – becoming proficient in primitive drawing could be much more valuable that using 'canned controls.' Take a look http://www.degrafa.com/ add a dash of creative thinking and you could dump charts… come up with a framework for reporting that is boot-licking delicious.

I'm working on a charting application with a requirement that individual charts be embeddable as widgets on arbitrary pages. I already have the bulk of the code in libraries, so have some freedom to explore different packaging. I had originally thought that it would make sense to create a module for each chart, and two separate hosts, one main application and one widget host. I understand that I would have to use RSLs and framework caching to keep the module size down. Frankly, I'm a little wary of that given the time constraints, and also because it depends on the later player. Another approach was to just build a different application SWF for each widget and modularize only when the main app becomes too large. Now I am considering the following: - the host is a single SWF with two states (widget and full). It loads either one, or several modules based on runtime config - the charts are in modules, optimized for the single host - the single app and multiple modules are in one project, so I can optimize for that app in Flexbuilder (though we do have continuous integration set up too) The only downside I can think of is that if the full state of the app has a lot of code besides the module code, the size of the widget download will be larger than it needs to be. On the other hand, it would allow the full app to be embedded as a widget, since the UX would be determined at runtime. And I suppose the full host state could itself be modularized. Comments?

RE: [flexcoders] How big does a SWF get before IE starts to worry?
You can profile a Flex 2 app in the Flex 3 profiler. You can profile any debug swf really. IE never worries, it just keels over and dies. Here's my top-five: 1. SWF size is not going to be your issue as much as run-time memory. I've heard of folks with multi-MB swfs and they aren't complaining that IE can't handle it. All complaints I've seen is about how much process memory (on Windows, the memory number you'll see next to your iexplorer.exe instance in the Task Manager) the application uses up and that, when it gets too big, IE dies. The number I keep hearing is in the hundreds of MBs. OK, so folks on slow networks wish the SWF was smaller so it would download faster, but once you get past that, it is all about run-time memory. 2. The Flex 3 Profiler can definitely help you tune your application, but it does not report the same numbers as the Task Manager because it only reports actionscript objects and not all of the other resources the player uses from the OS such as, on Windows, DIBs, HWNDs, DCs, etc. If you suck in lots of huge images, the Profiler will not show that but the Task Manager will, and that's the fastest way to get IE to choke. 3. Modularity is always a good thing. Pay as you go is usually a good thing. Only loading what you need and getting rid of it when you don't need it is usually a good thing. 4. Modules is a feature designed to assist the development of large applications by not requiring that you compile and link every byte of the SWF on every change, and to assist startup time by allowing you to load the SWF bytes you don't need at startup after startup. A single SWF will use less run-time memory than the same SWF broken into modules unless some of those modules are never loaded or get punted when no longer needed. 5. Application run-time memory usage can be code-bound, display-object bound or data-bound. A medium-sized app (500K SWF) I just looked at used up 35MB of process memory at startup. Roughly 10MB is just IE, another 10MB is the Player and of the remaining 15MB, 80% was attributed to the code. SWFs are zipped and expand at about 3:1, then are JIT-ed to machine code and other structures are setup to support classes, methods, etc. A SWF does not run from its binary as much as an .EXE file does. That app is considered code-bound, at least at startup. Now, every UIComponent is at least 6K, controls and containers are proportionally larger, so somewhere short of 1000 display objects, you've sucked up 6MB or more. 1000 seems like a lot, but it is 10 tabs in a tabNav with a 10x10 datagrid on it. Charts may have lots of display objects too. So if you have lots of grids and charts and not a lot of code, then you are display-object bound. Start bringing in bitmaps or requiring bitmap caches, and you'll definitely be display-object bound. Finally, some apps bring in 1 data records, some which are deeply nested. A simple bindable object is at least 50 bytes so with complex data objects, you can really eat up tons of memory and be data-bound. How you optimize for each scenario is pretty straightforward, but you have to know which scenario you are in, and the Profiler is not going to fully measure the memory that goes to code and display objects. Hope that helps, Rick's responses were definitely more fun to read. -Alex From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Josh McDonald Sent: Thursday, May 08, 2008 9:12 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] How big does a SWF get before IE starts to worry?
