It took many years for the Flash Player to gain acceptance, and it's still not a total success (read any posting on slashdot that is related to Flash to see what I mean). Throw on top of that Microsofts reputation in Internet Security and you have a user base that will be uneasy with the install. I see this going one of two ways. Silverlight takes more than 2 years to reach saturation, partially fueled by the reluctance of the population to upgrade to Vista. This causes developers to choose other options which in turn drive the next big web trend beyond RIA. Or Sliverlight is a moderate success and everyone is happy. Or (sorry, I just thought of this so it's actually 3 ways) Silverlight is a big success and clever developers like myself (I do totally rock ;) blend Flash, Flex, Silverlight and some other new emerging technologies that in turn drive innovation away from all the current RIA platforms to something far more advanced.

RE: [flexcoders] Re: Module GC question
When you call unload on a ModuleInfo, you are just releasing one reference to it. There's no practical way for us to keep track of all references to things in a module and go clean them up. However, while I suppose it is the safe approach to clean everything, you might be better served knowing what things to clean. It makes it clearer what the connections are between modules and forces you to have a cleaner architecture in order to minimize the number of connection points. Note also that event listeners are backwards. someObj.addEventListener(event, myEvent) doesn't make an additional reference to someObj, it makes a reference from someObj to the owner of myEvent. -Alex From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of kyle.vanvranken Sent: Thursday, April 19, 2007 8:26 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Module GC question So it would be best to remove all listeners that you can and set every var the module is using to null before unloading it to get that memory back. That's definitely doable I'm just surprised that unloading the module doesn't wipe out all those references. Thanks for the quick reply Alex!

Re: [flexcoders] Prana: IoC container for AS3
I think avoiding repeated code would a great advance if we use an IoC container that allows us only create the different code and inyect the shared functionality. Another great thing is AOP that would be a great thing since many different objects must face equal behaviour and we could do this as as aspect and inyect it by configuration. Maybe the problem is to think about how we must to adapt this kind of functionality to AS3 and Flex and not simply copy from the java/spring world to Flex. But for me is clear that many improvements in the upcoming months could be done with frameworks like Pranaq 2007/4/20, Brian Lesser [EMAIL PROTECTED]: Hi Carlos, et al, I have a question regarding the need for an ioc container for Flex as opposed to a pure AS3 or Flash project. Flex already provides a hierarchy of containers that contain controls and service proxies. The containers are usually responsible for setting the dependencies between controls and proxies. Setting dependencies can be done with databinding, simple assignment, or by setting up listeners. This is a very different situation from what a Java developer faces without an IOC container when writing servlets or JSP pages. In fact in Flex the built in visual state mechanism means we can set up dependencies and tear them down when states are entered and left. So, here's my question: what would an IOC container add that Flex doesn't provide and how would it improve our work or what we could do? Are you primarily thinking about aspects? Yours truly, -Brian Carlos Rovira wrote: Looks very promising :) Great! C.

Re: [flexcoders] Problem with loading module -- mx.core::LayoutContainer could not be found.
Hi Alex,
I don't think I'm doing something special when loading -- just using the
ModuleManager:
var manager:ModuleManager = new ModuleManager();
this.myModule = ModuleManager.getModule( url );
this.myModule.addEventListener(ModuleEvent.READY, moduleReady );
this.myModule.addEventListener(ModuleEvent.ERROR, moduleError );
this.myModule.load();
.. it does work if I publish the application to the same domain I'm loading
the module from. So I'm thinking the problem has to do with the local
filesystem not being in the same domain as localhost, as you mentioned.
I don't know why the LayoutContainer error is thrown when I run the app
locally, but as I said - the same code works if I publish both application
and module on the same host, so it does seem a bit strange to me.

Re: [flexcoders] Can someone explain this?

The problem I have is that I have several data grids that interact

visible).
When I programmatically set the width of the columns, if the columns
have not been shown (are not in the 'visibleColumns' array) I get a
null pointer error. See the stack trace below.
Since I can't get to the 'visibleColumns' collection, how can I set
the 'desired' widths of my columns without running into this error?
Also, looking at the actual code, they tried to check for some
timing
on whether they had calc'd columns. But they don't check if the
column
you're setting the width on is in the 'visibleColumns' list. This
seems like a relatively simple defect to fix... It should fall into
that upper if block, and set the width on the column itself, right?

I was thinking of the configuration from a CF8 + LCDS 2.5 integrated installation that is in Beta 2 right now that makes this much simpler (and avoids the need for configuring RMI to get this to work). http://labs.adobe.com/wiki/index.php/Scorpio Pete From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of João Fernandes Sent: Thursday, April 19, 2007 2:40 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] FDS / CF Endpoints Darren, when you request a fill, it will contact with rtmp or polling FDS server. Then FDS looks into the configuration and try to locate CFserver (not the client itself). Tries to connect to it (if no hostname is defined in the destination configuration) with RMI. ColdFusion accepts the connection if the IP is in the allowed IP list that you can find inside the CF administrator in the flex related window. Then if allowed, if checks for the CFC assembler, calls the fill method, returns to FDS and FDS returns to the client. The EndPoint must target always FDS and never CF. João Fernandes

[flexcoders] Communicating between Flex and Embeded Swf loaded with loadBytes
Hi
I have made a custom pre-loader for my Flex app that displays an
embedded swf:
[ Embed(source=/assets/ui/loader_panels.swf,
mimeType=application/octet-stream) ]
public var WelcomeScreenGraphic:Class;
public function WelcomeScreen()
{
this.loadBytes( new WelcomeScreenGraphic() as ByteArray );
}
This works fine but the swf needs to laod different xml files
depending on the localeCode set in the flash vars of the main Flex App.
How can I pass this variable into the swf so that it loads the correct
xml file?
Also is there a way for the flash file to dispatch an event or call a
function in the flex app when the animation has finished?
Thanks.

Adobe constructed a great product. The conception and architecture are excelent, but the comercial strategy is not so good. Macromedia had something like 4 years ahead of Microsoft, since Flex 1.5, that was a very good product too. Macromedia insisted to to seel it for US$18 k, nobody bought it Microsoft at that time did not exist in RIA Market. Then Adobe came and Flex became more accessible. But Adobe charges FDS in US$ 20K and does not pay attention to .NET developers.

Re: [flexcoders] FDS Scalability

Regarding scalability, it should work fine since they scale each one on their own side. I never heard of scalability problems for any of those 2.

[flexcoders] Getting progress events on Socket *write* (not read)
Is there a way to get a progress event on a socket write (flush)? Right now, the way I understand it, if you write data to a socket you have no way of knowing when the data has completely been flushed. This is a problem if you're writing a lot of data, because you could blow that buffer .. guessing the bandwidth (eg: by testing it) isn't a great solution either, for example, if you're on a wireless laptop that bandwidth may fluctuate and your original guess might be wrong. I guess you could continue to test the bandwidth connection, but that seems a bit unfortunate. Might be my only resolution here, though. Cheers, Tim.

constructor that take a non-empty string and convert it to true.
aww.
very weird.
anyway thank you and the others to help understand what is going on
here.
now i will try to minimize the damages :)

Hi,
Its not a bug. Note: the Constructor for Boolean in the docs.
Think about it as if you have the following:
var moo:String = Moo;
if (moo) {
// have a cow.
}else{
//no cow.
}
So, Boolean(false) is true!
var y;
var x:Object;
var b:Boolean = Boolean(false);
trace(b1 false is +b.valueOf());
b = 0;
trace(b2 (0) is +b.valueOf());
b = 1;
trace(b3 (1) is +b.valueOf());
b = 2;
trace(b4 (2) is +b.valueOf());
b = -1;
trace(b5 (-1) is +b.valueOf());
b = null;
trace(b6 (explicit null) is +b.valueOf());
b = x;
trace(b7 (unassigned null, undef) is +b.valueOf());
b = y;
trace(b8 (undef) is +b.valueOf());
b = (new Object() as Boolean);
trace(b9 (as not a boolean ie, null) is +b.valueOf());
-
b1 false is true
b2 (0) is false
b3 (1) is true
b4 (2) is true
b5 (-1) is true
b6 (explicit null) is false
b7 (unassigned null, undef) is false
b8 (undef) is false
b9 (as not a boolean ie, null) is false

[flexcoders] custom drag events for List -- how NOT to have scrollbar drag an item?
I have a list showing a variety of items. I use a custom ItemRederer to
diplay the list items, which I want to be able to drag from the list as
well.
When the user drags an item, I want the DragProxy to be a different look
than the ItemRenderer.
I couldn't figure out how to override the built in drag functionality,
so I went with the roll your own technique shows in the Docs.
Problem is, when there are enough items in the list to make a scrollbar
visible (policy is set to automatic), when I drag the scrollbar, I also
end up starting a drag of the item that is under (?) the scrollbar where
I clicked.
Below is the code I'm using to initiate the drag. All the handlers are
for the List. The renderer class is SongRenderer, and the proxy class
is SongProxy (there's also a Song class, which is what the items in the
List are).
Anybody suggest a way to do this, either by overriding the built in drag
events, or by somehow saying Yeah, unluess you're cliciking on the
List's scrollbar(s)?
Thanks!

[flexcoders] rowCount bug in DataGrid?
I have a datagrid held within a vDividedBox. I need to know the number of visible rows as the dividedBox size changes. I tried using the divider events (dividerPress, dividerDrag, dividerRelease) and checking the rowCount of the DataGrid, however it appears that the rowCount is not updated at the time of the divider events. Sometimes rowCound is not updated with the event at all or lags considerably behind the event. I tried watching in the debugger and it appears that rowcount is not updated with the resize all the time. Any ideas? Should I be using something other than rowCount? Thanks, Steven

[flexcoders] Fade Effect and StartDelay Issue/Bug?
Seems like I'm having an issue with the Fade effect and using startDelay.
I have the following Fade effect defined:
mx:Fade id=fadeIn duration=200 alphaFrom=0.0 alphaTo=1.0
startDelay=1000/
This is used by a canvas component:
mx:Canvas id=myCanvas
width=400 height=400
visible={cb1.selected}
showEffect={fadeIn}
hideEffect={fadeOut}
mx:Button label=test/
/mx:Canvas
cb1 is a checkbox to play around with the fading in and out of the
canvas. I'm starting out with the Canvas supposed to be invisible
(checkbox unchecked).
Here is the problem:
When the visible property for the canvas is turned to true, Flex makes
the canvas visible instantaneously and then after 1 second does the fade
in effect. What should be happening is that the canvas is staying
invisible and then doing the fade in.
Anyone run into this problem? Seems like a bug in Flex to me, but then
again, I could be overlooking something.
Thanks,
Jurgen

[flexcoders] Application design question: opinions welcomed
I am about to undertake the task of expanding a recently completed Flex app that utilizes Cairngorm. Its basically a workflow application to allow users to create large batches of PPT and PDF documents that are generated on the server. The existing application is for a specific type of document, and we're about to expand it to allow the generation of different kinds of documents, and I'm not yet sure how to best architect it. As it stands now, the application consists of the following screens, which for the most part are encountered in a chronological fashion. Dashboard - Create Worklist - Configure Documents - Preliminary Generation and Approval - Full Batch Generation - Document Delivery The app will eventually need to support the configuration and batch generation of several different types of documents. They will all require slightly different steps and levels of control. For instance, the first doc type we are adding will not utilize the Configure Documents and Preliminary Generation and Approval steps in the sequence described above. Document Delivery will be used for all doc types, and the layout of the screen should remain fairly consistent, but the logic behind the controls and specific data held in the components will vary from doc type to doc type. I realize this is very general, so I am really looking for overarching approaches. Do I need to do some sort of reverse code-behind, where I have a base MXML file for the screens that I can then extend/alter via script files? Should the whole deck of screens for each doc type be a module or should each screen be a module? Whats the best way to structure my Command and Event classes since I will have some generic and some that are doc type specific? Pointers anyone can give are appreciated, even if they're as general as suggestions on analysis patterns I can follow to better diagnose the situation myself. At this point I am just kind of stuck on where to even start on breaking things apart. Thanks, Ben

Re: [flexcoders] Prana: IoC container for AS3
Thanks Carlos,
I'll be interested to see what you come up with. Right now I'm
experimenting with the best way to use static methods to handle
cross-cutting security concerns within custom components. For example a
combo box may only be able to show certain options to a user based on
the user's role. The combo starts off with all the options available but
must filter them before displaying them. To do that it calls a static
method of a RoleFilter class. I'm not sure if that's the best way to go
about it though. Here's the script from within a custom combo box as an
example:
mx:Script
![CDATA[
import com.somecompany.security.RoleFilter;
private function init():void{
filterData();
}
public function filterData():void{
dataProvider =
RoleFilter.filterArrayCollection(unfilteredCollection);
}
]]
/mx:Script
Note: unfilteredCollection is just an ArrayCollection of objects.
Now, that's not a lot of code, but what bothers me is that I'd rather my
custom combo box not know anything about my RoleFilter class. In fact
I'd prefer it not know anything about filters at all. So, even though
this works fine, I'm trying to come up with something more elegant. So
far having the combo box's container set this up hasn't looked right
either. So again, I'm interested to see what you end up with.
Yours truly,
-Brian

2007/4/20, Brian Lesser [EMAIL PROTECTED]:
Hi Carlos, et al,
I have a question regarding the need for an ioc container for Flex as
opposed to a pure AS3 or Flash project. Flex already provides a
hierarchy of containers that contain controls and service proxies. The
containers are usually responsible for setting the dependencies between
controls and proxies. Setting dependencies can be done with databinding,
simple assignment, or by setting up listeners. This is a very different
situation from what a Java developer faces without an IOC container when
writing servlets or JSP pages. In fact in Flex the built in visual state
mechanism means we can set up dependencies and tear them down when
states are entered and left. So, here's my question: what would an IOC
container add that Flex doesn't provide and how would it improve our
work or what we could do? Are you primarily thinking about aspects?
Yours truly,
-Brian

[flexcoders] LiveCycle Data Services PDF
I have been looking at the LCDS PDF creation capabilities and I have found that the PDF's created, 1) Cannot be previewed in the flex app, which means that the user has to deal with annoying popups etc... 2) Cannot be viewed in OSX Preview. Unfortunately, in my case, over 50% of my end users are running OS X and thus do not have Reader installed AND furthermore expect to be able to open PDF's in Preview. Does anyone know of a server-side conversion to make the PDF's compatible with Preview. Is this something that we would have to purchase LiveCycle Forms to accomplish?

RE: [flexcoders] rowCount bug in DataGrid?
You might check rowCount on updateComplete on the DataGrid From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Steven Lira Sent: Friday, April 20, 2007 8:25 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] rowCount bug in DataGrid? I have a datagrid held within a vDividedBox. I need to know the number of visible rows as the dividedBox size changes. I tried using the divider events (dividerPress, dividerDrag, dividerRelease) and checking the rowCount of the DataGrid, however it appears that the rowCount is not updated at the time of the divider events. Sometimes rowCound is not updated with the event at all or lags considerably behind the event. I tried watching in the debugger and it appears that rowcount is not updated with the resize all the time. Any ideas? Should I be using something other than rowCount? Thanks, Steven
RE: [flexcoders] Communicating between Flex and Embeded Swf loaded with loadBytes
If the swf is player 8, the code will be stripped so there won't be code

If the swf is player 9/cs3, then you should actually create a swc and

Subject: [flexcoders] Communicating between Flex and Embeded Swf loaded
with loadBytes
Hi
I have made a custom pre-loader for my Flex app that displays an
embedded swf:
[ Embed(source=/assets/ui/loader_panels.swf,
mimeType=application/octet-stream) ]
public var WelcomeScreenGraphic:Class;
public function WelcomeScreen()
{
this.loadBytes( new WelcomeScreenGraphic() as ByteArray );
}
This works fine but the swf needs to laod different xml files
depending on the localeCode set in the flash vars of the main Flex App.
How can I pass this variable into the swf so that it loads the correct
xml file?
Also is there a way for the flash file to dispatch an event or call a
function in the flex app when the animation has finished?
Thanks.

Re: [flexcoders] Prana: IoC container for AS3
Hi Brian,
I think you are referrin to Christophe and his project Prana, although I'd
want to contribute if I can :)
2007/4/20, Brian Lesser [EMAIL PROTECTED]:
Thanks Carlos,
I'll be interested to see what you come up with. Right now I'm
experimenting with the best way to use static methods to handle
cross-cutting security concerns within custom components. For example a
combo box may only be able to show certain options to a user based on
the user's role. The combo starts off with all the options available but
must filter them before displaying them. To do that it calls a static
method of a RoleFilter class. I'm not sure if that's the best way to go
about it though. Here's the script from within a custom combo box as an
example:
mx:Script
![CDATA[
import com.somecompany.security.RoleFilter;
private function init():void{
filterData();
}
public function filterData():void{
dataProvider =
RoleFilter.filterArrayCollection(unfilteredCollection);
}
]]
/mx:Script
Note: unfilteredCollection is just an ArrayCollection of objects.
Now, that's not a lot of code, but what bothers me is that I'd rather my
custom combo box not know anything about my RoleFilter class. In fact
I'd prefer it not know anything about filters at all. So, even though
this works fine, I'm trying to come up with something more elegant. So
far having the combo box's container set this up hasn't looked right
either. So again, I'm interested to see what you end up with.
Yours truly,
-Brian

2007/4/20, Brian Lesser [EMAIL PROTECTED] blesser%40ryerson.ca:
Hi Carlos, et al,
I have a question regarding the need for an ioc container for Flex as
opposed to a pure AS3 or Flash project. Flex already provides a
hierarchy of containers that contain controls and service proxies. The
containers are usually responsible for setting the dependencies between
controls and proxies. Setting dependencies can be done with
databinding,
simple assignment, or by setting up listeners. This is a very different
situation from what a Java developer faces without an IOC container
when
writing servlets or JSP pages. In fact in Flex the built in visual
state
mechanism means we can set up dependencies and tear them down when
states are entered and left. So, here's my question: what would an IOC
container add that Flex doesn't provide and how would it improve our
work or what we could do? Are you primarily thinking about aspects?
Yours truly,
-Brian

The easiest solution if you want to guarantee that your root sprite catches everything is to simply fill its graphics with a rectangle with zero alpha. You won't see anything, but all the pixels of the hit area will be set. Troy.

If you click anywhere on the background of the application you should get mouseDown events. I do in my tests, and the target is the application because it totally covers the SystemManager. Are you in a different topology or seeing something else?

After some research and googling, the conclusion that I can draw is that for mouse event, it is abit unusual. Apparently, the main application class (which by default extends from a Sprite class), will not receive mouse events directly. Mouse events seemed to be the only exception, all other events like the keyboard events, enterframe work fine. In order for the main application class to receive mouse event, it must be through a child (capable of dispatching a mouse event) in the its display list via bubbling or capture phase. According to Colin Moock, Mouse interactions with vector content drawn via the graphics property of a .swf file's main class do not trigger mouse events. However, mouse interactions with vector content drawn via the graphics property of any other instance of InteractiveObject or its subclasses do trigger mouse events. So I guess, using the bitmap object probably fall under mouse interactions with vector content drawn via the graphics property?

How come it doesn't trace out? Did you forget to add your Sprite to the Stage? e
[flexcoders] How to prevent Flex Apps from always loading from server. They never get cached
Hi All, How can one direct Flex to load from Cache and not from the server if both files are the same. Seems like Flex Apps always load from server even if both local cached swf and server swf are the same. As always, Thank you for all the help and support.

[flexcoders] Flash 9 Stage size - 2880 x 2880 limitation

Re: [flexcoders] Flash 9 Stage size - 2880 x 2880 limitation
I have a friend creating a huge wall-display project with a screen resolution of around 3600 x 3600 pixels. So, he should be able to create an app that's 1800x1800, and then simply go fullscreen which will scale Flash to the needed res (what you were saying).

Re: [flexcoders] Issues with Flash Gateway
The gateway url requires an ending forward slash http://myserver/flex2gateway/ As for projects that need CF, I deploy them to the test server (which is on another machine as well). I have a mapped drive (P:\) that maps to the CF Root on the other machine. So when setting up a new project I point to a folder on the mapped drive as output folder and specify the output url Output folder: P:\MyProject\ Output folder URL: http:\\mysever:8300\MyProject\ Whenever I Run or Debug an application, it gets deployed to P:\MyProject and opens the browser with http://myserver:8300/MyProject/name_of_app_mxml.html regards, Muzak - Original Message - From: b_clingan [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Friday, April 20, 2007 1:09 PM Subject: [flexcoders] Issues with Flash Gateway I'm developing and building on my local machine, but the ColdFusion server is on another machine in the network.

[flexcoders] Reload (reinitialize) application
What is best way to reload / reinitialize the whole flex application from code? I want to be able to reset state of my application on timeout event, it seems that the easiest way is to somehow recreate the whole app or at least main view. Something like: Application.application = new MyApplication() but obviously Application.application is read only property. How else it can be done? Thanks, rd
Re: [flexcoders] Re: Will Microsoft's new Silverlight Player Kill our beloved Flex ?
For the record, I was very vocal about Flash's potential all those years ago as well (In 2004, I made this post http://www.mossyblog.com/archives/276.cfm). I'm not trying to stir the politics, but i even look at the CS3 sku's and ponder what the hell is going on? (keep it simple). Flash has always been one of these pieces that I thought had so much more potential than what it has today, I mean you're right FLEX 1.0 was not only ahead of the game - but - pre-AJAX movement, so there was enormous potential here and it's why since i'm in an openly honest mood I hate the very though LiveCycle + FLEX are living side by side another as I get that feeling again Here we go, different name, numbers stay about the same. (Yes I know I'm now being negative and being a Microsoft employee it's now sounding like FUD, but in 2004 I had these feelings and I was right, 2007 they are back, difference is i have MS Logo on my back). I love FLEX, just hate the distractions around it. On 4/20/07, mvbaffa [EMAIL PROTECTED] wrote: Adobe constructed a great product. The conception and architecture are excelent, but the comercial strategy is not so good. Macromedia had something like 4 years ahead of Microsoft, since Flex 1.5, that was a very good product too. Macromedia insisted to to seel it for US$18 k, nobody bought it Microsoft at that time did not exist in RIA Market. Then Adobe came and Flex became more accessible. But Adobe charges FDS in US$ 20K and does not pay attention to .NET developers. Well it seems to me that this is another big mistake. if Adobe continues with this kind of comercial strategy, i am afraid that our beloved Flex will loose the race. --- In flexcoders@yahoogroups.com flexcoders%40yahoogroups.com, Scott Barnes [EMAIL PROTECTED] wrote: On 4/20/07, Michael Schmalle [EMAIL PROTECTED] wrote: I have to put my 2 cents down for prosperity sake. 4 which is important :) All you people that live in cities and constantly sicken yourselves by your own pollution, need to live on a mountain for a couple years, look back at what you say and see how hilarious it all is.

[flexcoders] Is there any event fired after sorting the datagrid ?
Hi All, Is there any event fired after sorting the datagrid. I mean if I click the datagrid header then DataGridEvent.HEADER_RELEASE event is fired and rows get sorted, now i want an event to be fired when the sorting is done. I tried CollectionEvent.COLLECTION_CHANGE but didn't worked. Thanks Arpan __ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
