[flexcoders] Re: Deleting row datagrid | Itemrenderer shows incorrect data

[turbo_vb]

Your CheckBox itemRenderer is getting recycled after the delete.  Use a
custom itemRenderer for the CheckBox.

Re: [flexcoders] Application requiring streaming data

[Evan Klein]

You are looking for messaging services. Messaging services come out of the
box with BlazeDS and Livecycle Data services.

Both products have a Java API for creating the producer components to push
messages down to clients.

Livecycle , however is about $40K / CPU and has advanced functionality such
as RMTP channels, guaranteed message delivery, throttling, etc.

Give this an example a try

[flexcoders] ImageSnapshots, embedded binary, and local-with-networking

[kazoobrewer]

I'm having issues taking ImageSnapshots in my local-with-networking SWF.

The content it doesn't like is images (Loader instances) loaded from an 
embedded blob:
 [Embed(source="payload.zip", mimeType="application/octet-stream")]
   
The blob is zipped, so there's some byte manipulation on the source data before 
going into Loader.loadBytes:
 sourceImageLoader.loadBytes(data, 
 new LoaderContext(false, ApplicationDomain.currentDomain, null));

I've tried with a null LoaderContext to no avail as well.

Is there any setting I can use to bless the data sufficiently to make this 
scenario work?

Thanks much,
michael

Re: [flexcoders] How do i install the debug player?

[Oleg Sivokon]

Sorry, this may upset you, but FB and Flash player aren't really related...
also there's no need to install standalone player, it's just not a program
that requires installation, after you run any copy of it it will create a
file association to SWF files (will make itself a default program to open
files with SWF extension). You may also do that from "folder options"
dialog. It is true they may try to change that to whatever version of player
they came bundled with right when you install them, but later they never try
to change that.
Silly thing about FB though is you cannot configure it to use the copy of
the flash player that you want... it has no such setting... Regarding your
other issue with unistaller, I personally never had it, but, this page seem
to have some good info (although dated)
http://kb.mozillazine.org/Flash#Windows_and_Mac . Some other adobe products
may sometimes try to install their own versions of player. This issue was
discussed several times and Adobe promised to do something about it in the
future releases...
Since I need multiple different versions of Flash player for testing, I
first was switching the SDKs (every SDK comes with the set of debug players
- find them in the runtimes folder), but that's not comfortable, so, I move
them to the Program Files/Flash Player/version/{debug|release}. Could sound
a little messy, but once I made it a habit any time I need to get a new
standalone version I just put it there, it never gave me troubles.

Best.

[flexcoders] How do i install the debug player?

[Clark Stevenson]

Hey guys.

I installed FB4 tonight for the 60 day trial and also Flash.

Everything was great but obviously i need a debug player as some .dll was
not found.

I downloaded the latest debug from here:

http://www.adobe.com/support/flashplayer/downloads.html


Firstly:

Active x wont install because it complains that i have a new version of the
flash player and i should goto the standard download of the player in order
to update.

The firefox plugin installed ok, but thats really slow from launching

I also downloaded a 5mb projector debugger... flashplayer_10_sa_debug   <---
this is what i want! So i dont need to wait for a browser to kick in.



So I headed over to the uninstaller page:

http://kb2.adobe.com/cps/141/tn_14157.html

Ran it, restarted Windows.


I tried to install the Active X plugin again and got the same deal It
informs me i have a newer version already installed.


I got rid of Flash and FB4, restarted, reinstalled both, then when i opened
FB4 i got "You must install the flash player" on the welcome tab.


I did an other hour of trying but then FB4 started giving me "Java point
exception" or something like that when i tried to hit Debug.


I then spent a while going through the preferences trying to find some
option to launch the debugger directly with flashplayer_10_sa_debug,exe but
i couldnt find an option.


So thats pretty much sapped my evening. Does everyone have a clue how i can
simply install FB4 and a Debug player? Is there some order i should install
CS5 FB4 Debug Players? Can i copy flashplayer_10_sa_debug to a folder where
FB4 will recognise it and if so where?

Trace() What a dear friend.

Thanks for your time on this.

Clark.

[flexcoders] how do i make a function call to a class bindable?

[luvfotography]

how do I make a function call to a package bindable?

when I call the public function clear(), the bindable class doesn't get 
updated??  ie student.fname or student.lname

ex:

package {
  [Bindable]
  public class student{
 private var _fname:String;
 private var _lname:String;
  
  public function student( fname:String, lname:String):void {
 _fname = fname;
 _lname = lname;
  }
 
  public function clear():void {
 _lname = '';
_fname = '';
}

public function set fname(value:String):void {
   _fname = value;
}
public function get fname():String {
return _fname;
}
public function set lname(value:String):void {
_lname = value;
}
public function get lname():String {
return _lname
}
}
}

Re: [flexcoders] Re: Strange Behavior When Loading Sub Application

[Alex Harui]

Thinking about this a bit more, every child of the sub-swf except its 
systemmanager should get an ADD_TO_STAGE around the time of applicationComplete 
in the sub-swf.  Flex builds the SWF’s ui off-stage.  So maybe there’s 
something else going on.

Re: [flexcoders] Flex 4 - Datagrid column header and data problem

[Alex Harui]

That is expected.  A "." in the dataField means that the column should
display sub-properties of complex objects.  You can set the headerText
separately from the dataField.

Flex SWFs must be on-stage in order to load.  Are you worried about missing an

Re: [flexcoders] how to style a ComboBox - Dropdown ?

[Alex Harui]

It depends on the dropdown.  The default is List.

[flexcoders] Application requiring streaming data

[sasuke]

Hi all,

I'm currently working on an use case/application which is something along
the following lines:
When the user successfully logs in the application, he would be shown a
graph/some statistical data. This data would be real time in the sense that
it would be updated with a granularity of around 100ms at the server which
needs to be pushed ASAP to the client.

Now, using services like WebServices, HttpService etc. would be a
performance killer in my case given the time/resources taken during
connection creation/tear down. Using long lived connections for HTTP might
end up failing if the proxy server decides to "cache" the response till the
stream is closed. Also, given that HTTP is a request oriented protocol, the
client would have to "beg" for changes before the server sends them to the
client.

So my question is: Which would be the most performant and viable solution
when it comes to retrieving streaming data or the server continuously
pushing data to the client once the client registers itself? It would be
much appreciated if you could share your similar experiences with such
requirements.

TIA,
sasuke

[flexcoders] Flex 4 - Datagrid column header and data problem

[Kovács Richárd]

Dear List,

I am new to flex, and to the list as well.

I have a very strange behaviour which I cannot really understand.

There is a Datagrid in my app, and there is an arraycollection
connecting to it. The column's headers of the Datagrid come from another
arraycollection. The header sometimes contains dots ("."). When it does,
the column header appears correctly but the data in the column does not
appear at all! There are rows, but no values!

I have tested it, and when the column header should contain a dot, the
values disappear.

First of all please let me know if this is a "normal" behaviour or I am
doing something terribly wrong.

I didn't want to include a whole bunch of source code in the first
email, so let me know if you need any.



Thanks in advance,
Richard

[flexcoders] Re: Strange Behavior When Loading Sub Application

[jmbo...@bellsouth.net]

Alex,

Your suggestion will work and in fact, that is the way we were doing it. 
Unfortunately, we needed to create a Robotlegs context so that we can listen 
for ADD_TO_STAGE events and allow it to automatically mediator our view 
components (see below).  That is why I added the sub-app as a child later.  Any 
other ideas how to make the current code work?


// Inject dependencies into the module and 
initiate the context since autoload is set
var subApp:IModule = event.moduleApp;
injector.injectInto(subApp);

// Make sure the content fills the page
var subAppComponent:SubAppBase = 
SubAppBase(subApp);
subAppComponent.percentHeight = 100;
subAppComponent.percentWidth = 100;

/* Add to contentViewStack here based upon 
position
   Simply add as a child to the stub canvas 
that already
   exists for the module
 */
var index:int = _moduleArray.getItemIndex(swf);
var canvas:Canvas = 
Canvas(contentViewStack.getChildAt(index));

canvas.addChild(subAppComponent);

Hi, Richard;

I am not guaranteeing this will be the case for what you are trying to do, but 
I have found when trying to customize ListBase components that often the large 
methods will have smaller, protected, methods that you can find and hook into 
if you're willing to dig through the class structure to find them.

Yep, this is a typical bug-free Flex behaviour

Try to delete all project from the workspace, restart FB and recreate projects

[flexcoders] Need your help to do my mini project.

[Sathya]

Hello,
  I have to do my mini project. My guide advices me to do in cairngorm 
framework. And i have the required soft-wares (Flex Builder 3, Flex Builder 3 
Plugin, Eclipse 3.4, 3.5 and 3.6 , Cairngorm plugin (bin files) and Zend studio 
for eclipse etc..). But i do not know how to merge merge all these things.
  I noticed the steps in 
"http://www.technyforum.com/forum/yaf_postsm19_Cairngorm-Plugin-with-Flex-Builder-3-Eclipse-plugin-and-Make-it-working-with-Cairngorm-221.aspx";.
 But i can not move on the 5th step and can not merge the softwares.
  So Need steps to merge all these things (installation steps) to do my 
cairngorm project in "Caingorm framework" (Cairngorm plugin with flex in 
eclipse)..
  Help me..

[flexcoders] Re: Issue:Authentication issue on edge server + LCDS 3.1 java based loadtesting tool

[Mete Atamel]

Hi Sanjit,

First off, ChannelSet#login and ChannelSet#logout are the preferred ways of 
authenticating with BlazeDS/LCDS. Producer/Consumer/RemoteObject#setCredentials 
would work but the problem with setCredentials method is that it doesn't return 
an AsyncToken and hence you can't listen for success/failure. Also, 
setCredentials method does not send the credentials to the server until the 
Channel is connected, it simply caches them and sends them along with the 
connect request. The problem is if there's a failure as the Channel connects 
(eg. RemoteObject method doesn't exist) and an authentication failure too (eg. 
wrong credentials), then distinguishing between the RemoteObject failure with 
the authentication failure becomes difficult. So, that's why you should use 
ChannelSet#login/logout before doing anything else, and once the authentication 
is successful, go ahead with what you need to do. BlazeDS source tree has an 
example of this here:

http://tinyurl.com/27y2zd5

Second, the load-testing-tool in LCDS 3.1 does not support authentication or 
SSL (RTMPS, HTTPS) yet. By default, the LCDS Edge Server requires that clients 
are authenticated at the edge tier before the request is forwarded to the 
backing LCDS app. This is for security purposes but the good news is that for 
testing purposes, there's a switch called "require-authentication" which is set 
to true by default and you can set that to false under GatewayService 
configuration:


   
  
 false
   ...

That basically disables the requirement that clients are authenticated at the 
edge tier. 

This should enable you to test your Edge+LCDS app without needing to add 
authentication stuff in the load-testing-tool.
