Re: [flexcoders] XML, does it have to be RSS?

[Paul J DeCoursey]

What does the rest of your xml look like? The example you provided was 
the root element and it had namespace declarations. removing those and 
keeping the same xml following that would be the problem.

Re: [flexcoders] Advanced Flex Authentication - limiting a user to a sinlge logon of a gieven app

[Paul J DeCoursey]

Might be able to accomplish that using Remoting, I don't think you'll be 
able to accomplish that on the web without some way of knowing for sure 
that the user has lost it's connection.  Perhaps if you expire sessions 
after a very short time, like 30 seconds, and constantly ping the server 
from the app.

Re: [flexcoders] Flex cookbook article: Flex2 XML Reader Can Create UIComponents

[Paul J DeCoursey]

You can easily integrate a compile on demand system using the Flex SDK 
and Tomcat.  The problem is the compilers are not very fast.  I'm 
guessing that the Apache/IIS module does some caching so that compiles 
run faster because they don't have to reload large libraries each time.  
Once the compiler is opened up a little more you should be able to 
implement this kind of thing.

Re: [flexcoders] Re: Flex cookbook article: Flex2 XML Reader Can Create UIComponents

[Paul J DeCoursey]

The Apache/IIS module is a Flex compiler that compiles the MXML just 
before serving.  Similar to JSP, ASP, PHP. and so on.  It is not 
MXML at runtime.

I'm sorry, I misunderstood.  I thought you were refering to the ability 
to use multiple monitors on a Mac. To tell you the truth what you are 
describing is completely new to me. I've never even heard of doing that 
on windows.  When I get in the office I will try it on my workstation

String is not a primitive, it is a class.  It is declared(public final

Re: [flexcoders] File Upload I/O error only on Mac

[Paul J DeCoursey]

I've seen this as well.  But it has not been a priority yet to 
investigate it, so I don't really know what is going on there.  I was 
thinking it may be sandbox issues.  Or perhaps a bug in the player.  Let 
me know if you discover anything.  Unfortunately it will be weeks before 
I get around to looking at it more.

I agree.  For the most part Flash/Flex is a user interface. 

I also think that it's a great idea to do processing in Flash, but we 
have to think differently.  People might think I'm crazy but I think 
that the way we need to think here is similar to how developers need to 
start thinking to take advantage of multi-core/multi-processor 
machines.  We need to break large tasks up into independent chunks that 
can be run from a queue.  In the Flash world that queue will run 
sequentially, but in other applications they could be run in parallel.  
I may be getting off-topic with that. Bottom line is we can't really 
compare Flash to Java or C#.

Although you declare test as a function it is not used as one.  When you

Re: [flexcoders] Re: Programatic Icon

[Paul J DeCoursey]

Ok, because I'm a big loser and I don't like using mx_internal... sorry 
that I'm so lame Mike...  but here is a modified version that doesn't 
use mx_internal.

Basically three things change from Mikes example.

private function changeIcon(event:MouseEvent):void {
myPanel.setStyle("arrowColor", 0xff);
}

I set a style rather than a property on an object we can't safely access.

on the Icon class I add this metadata
[Style(name="arrowColor",type="uint",format="Color",inherit="yes")]

and updateDisplayList becomes this

override protected function 
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
   super.updateDisplayList(unscaledWidth, unscaledHeight);
   if(this.parent!= null && this.parent is UIComponent) {
   if((this.parent as UIComponent).getStyle("arrowColor")) {
   _color = (this.parent as 
UIComponent).getStyle("arrowColor");
}
   }
   graphics.clear();
   graphics.beginFill(_color, 1);
   graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
   graphics.endFill();
   }

Might be possible to improve the logic in the part where it gets the style.

None at the moment, but I've heard that they are working on a way to

Re: [flexcoders] wmode=transparent : any limitations to expect ?

[Paul J DeCoursey]

Where is this not supported?  I have tested most and found it to work as 
expected.  Mostly that html elements can appear over the flash component.

Re: [flexcoders] wmode=transparent : any limitations to expect ?

[Paul J DeCoursey]

All mouse related events do not detect modifier keys. This was a painful 
issue because our app depended on being able to select multiple items 
from a list and that's not possible when control and shift are not 
registered on a mouse click.  MSIE did not appear to have this 
limitation, but sometimes didn't register mouse events at all in some 
places in the app.  I think that was because "invisible" html layers 
were obscuring them from the mouse event.  In time we cleared those up 
by cleaning up the CSS for IE.  No workarounds yet available for the 
mouse issues in other browsers.  Other than that I didn't see any other 
issues.

Re: [flexcoders] Programatic Icon

I've been able to get it to work for buttons and the like by extending 
ProgrammaticSkin and passing in the class.  I've never even used the 
icon on a TitleWindow to even know how it's supposed to work.  It should 
work, because everything is a class, but it might not know what to do 
with it.

Re: [flexcoders] Re: Will Microsoft's new Silverlight Player Kill our beloved Flex ?

Ummm no IE does not work on the Mac, the last few versions were

Re: [flexcoders] Will Microsoft's new Silverlight Player Kill our beloved Flex ?

[Paul J DeCoursey]

All I have to say is it's Microsoft, if they kill anything it's not on 
the merits of their product... it's brute force.  This is not a threat 
to Flash/Flex by any means.  Microsoft will never be able to create a 
truly cross platform product.  All of their past efforts have been 
clumsy at best, even on their own platform.

Re: [flexcoders] Re: Versioning swf files for bug reporting

[Paul J DeCoursey]

I have a java class that generates a build.as file that is included in

I put in a build id, gotten from subversion.  I also include the date 
for the version and who did the build.

If I ever get around to it I will blog about this.

Re: [flexcoders] How do I read Response after FileReference uploads a file?

[Paul J DeCoursey]

I did something similar.  Before the upload I get a token, I pass that 
token on the querystring of the upload.  Once complete I use that token 
to get info about the upload.  I also use this token for authentication 
purposes.  We have had a lot of trouble with file uploads not sharing 
sessions with all of the other requests in the app.  Another advantage 
to the token is we have a queue of files that the user is uploading from 
in the app.  With the token we don't have to retrieve the response data 
right away, or it can be ignored altogether.  We also expire the tokens 
after a certain period of time because we do use them for auth as well.  
Anyway, it's probably overkill for your project, but I thought I'd share.

Several ways. 
1)  Fail gracefully
2)  If a service changes and is incompatible with old clients then do 
not reuse the url.  For example all of our front ends have version 
numbers in the url so we can quickly determine if the user is on an old 
version.  Our services are the same way, except that for the most part 
they don't change.  We spend a lot of time making sure it's what we need 
before.
...  This is not a difficult problem, there are a lot of ways to get 
around cache servers and cached browser issues.

Re: [flexcoders] Re: Passing an object reference as a property

[Paul J DeCoursey]

Those are valid use cases, and your suggestion isn't a bad one. (Note: 
the following is my mind wandering and isn't really related)  I 
speculate that there is a better way. Within those use cases there are 
still some issues, what if the object in question is a member of a 
collection?  I think what we need is XPath on the object model.  I 
better stop thinking about this or I'll end up porting JXPath to AS3 and 
my clients will wonder why their projects aren't getting done.

[flexcoders] Problems with EventDispatching

[Paul J DeCoursey]

I have some classes that are EventDispatcher but not DisplayObjects.  I 
have maybe 10 or 15 of these classes and a few of them will not bubble 
events to the SystemManager.  I have created the Events to bubble but 
they will not.  If I listen on the object I receive them.  My problem is 
the Objects I want to receive the events on don't know about the Objects 
that dispatch them and I don't want them to know about them.  Has anyone 
had a problem like this?

Re: [flexcoders] Re: Creating Thumbnails from large images on the fly. Possible?

[Paul J DeCoursey]

Best way to do it is to have some sort of server process that scales the 
image and store that scaled version for future requests.  I had built a 
system quite a while ago for doing Image Management and it would scale 
multiple sizes of each image on upload and then you can download the 
appropriate size as needed.  Much like how flickr works.  We built it in 
java.  If you can run java I can try and dig up some of the code.

In this case it is since the source for URLRequest is not available, 
URLRequest is a flash class not a mx class.  To make it work we would 
need to implement the entire HTTP client stack using sockets.  Not a 
small undertaking.

I think what you need to look at is the dragComplete event.  This will 
fire everytime a drag has completed.  So you will have to do some

Re: [flexcoders] compc - degrees of specification

[Paul J DeCoursey]

I've been doing this same thing.  Are you using the ANT Tasks from the 
Labs?  I've found that it works better to break it up into separate 
libraries.  Then I use the depends and uptodate options so I don't 
compile unless something has changed.  If you are using the ANT tasks 
from the labs you should be able to use filesets with wildcards (**/*.as 
and **/*.mxml) to catch all the files you need.  We are not using the 
ANT Tasks ourseleves but we plan on migrating soon.  For now we use java 
tasks and pass in the jars for the specific compiler, and then we need 
to explicitly set each file we want included in the swc.

Uncheck the "Coy non-embedded files to output directory" option in the

I'm not sure what you mean by memory leak. But in your source you do 
keep a reference to the HttpService and that will keep the XML hanging 
around in memory for a while. That may be the issue. Also I looked at 
your xml files, and pbentries.xml is full of some bizarre characters. 
They display as Ő (which is not UTF-8 encoded by the way) in notepad on 
winXP and they crash jedit and firefox if I try to view the file. I am 
guessing they have something to do with the problem.

I can't comment on what others are doing, I can only comment on the fact 
that it does not out of the box support PUT and DELETE.  Those are the 
operations we needed and the original poster needed. It's silly to argue 
the semantics of this, if you think it's so easy to implement PUT and 
DELETE then be my guest.  Perhaps one day I will port Commons HTTPClient 
and it will solve our problems.

Indeed, and since we had heavy use of DELETE and PUT we had to make the 
determination of what was easier and more cost effective.  We choose 
SOAP because Flex has good SOAP support.  We avoided implementing DELETE 
and PUT because we don't have any protocol developers on staff.  So 
until Flex has out of the box support for all the HTTP verbs then it 
does not support REST.
