Re: [flexcoders] Which AIR SDK to use with Flex?

[Mark Jonkman mark.jonk...@comcast.net [flexcoders]]

If you can also add the command line option -useLegacyAOT yes to make sure. The 
issues with new compiler 'fast compiler' seem to be with overridden methods not 
having same number of parameters and using swcs compiled with older versions of 
the compiler. So your mileage may vary from mine or others depending on your 
project.

My project is huge so it would take hours to unwind issues caused by the fast 
compiler. Though my iOS builds which average 30min went down to 15 min with new 
compiler.

RE: [flexcoders] Which AIR SDK to use with Flex?

['Mark R. Jonkman' mark.jonk...@comcast.net [flexcoders]]

I’m guessing it mostly has to do with mxml compiling. The old compiler would 
have to handle both types of input – ActionScript and MXML and generate 
ActionScript code based on the MXML and then generate the final product. If 
your Adobe and you no longer support MXML yourself then there is no reason to 
keep it around in future generations of the compiler – especially where speed 
becomes an issue. 

 

I hit a lot of problems this week with the new fast compiler. AIR SDK 15 
switched from using the legacy compiler to the new fast compiler as its default 
compiler. My project uses just a small portion of the FLEX framework – just 
enough stuff to connect with the backend server running BlazeDS and sending 
stuff over AMF. As a matter of fact we actually put the classes we used into 
our own project and as far as we knew, no longer linked against any of the Flex 
framework SWCs. However after the switch to the new AIR SDK 15 the project 
started blowing chunks. It would not find about 8 interfaces and classes from 
the Flex framework.  Eventually I traced it down to possible being the swc 
cache that Flash Builder stores in the workspace .metadata folder (I think). I 
deleted all the files in the swc  cache and the errors finally went away. It 
took hours to track that down. Then I finally got the project compile into an 
iOS IPA file and installed it on my iPad – crash after a few seconds of 
running. AIR simulator no problem, iOS Simulator no problem. But a debug or 
release runtime and crash.. Then I realized that they had changed the default 
compiler to the fast, switched back to the legacy AOT compiler and everything 
worked perfectly. 

 

Unfortunately if iOS is your target you have almost no choice but to upgrade to 
AIR SDK 15. Apple changed the requirements for uploading and all the old SDKs 
will not produce an IPA that will be accepted (unless you experiment with 
changing the linker and that sounded more like Voodoo then a long term 
solution). And the AIR SDK must be the one from at least Oct 14, 2014. 

 

If you did not already know – The AIR SDK is located in two places one is the 
Flash Builder 4.7/eclipse/plugin folder (Used by ActionScript projects) and the 
other is in the Flash Builder 4.7/sdks folder. The plugin folder is for 
ActionScript only projects and the other in the sdk folder is for Flex 
projects. At least as near as I can determine.

 

I would download the default AIR SDK to use with any ActionScript projects – 
it’s the SDK that gets put into the eclipse/plugin/actionscript compiler…. 
Location.

 

For Flex projects, download the alternative and drop it into the sdks/4.6.0 
folder in Flash Builder. 

 

This way you have both compilers setup and useable based on the type of project 
your working on.

 

If you hit the same situation I did with iOS output, then on the project 
settings, iOS settings – click customize launch button, click add parameter, 
enter –useLegacyAOT for name and for value enter yes. Then click the before.. 
radio button and choose –provisioning_profile (or something like that). I don’t 
have my work computer open so I might be off on a couple of name of the before 
radio button and the entery in the drop down list – but it’s the only entry 
with provision profile or similar in the name.

RE: [flexcoders] Compiling and debugging against a remote Coldfusion server

[Mark Fuqua]

Thanks for the reply Brendan.  However, I think I did a bad job communicating 
what I was looking for.  I can set up the environment locally, but the guy I 
hired has never used coldfusion or remote objects.  I hired him to help with an 
existing Flex application I did myself (very green).  It is running locally, on 
my dev machine and remotely on two different websites (slightly different 
code…logos/images/colors etc.). 

 

I wanted some help doing some stuff with filtering and sorting 
listCollectionViews and ArrayCollections…he has never worked with Coldfusion 
before and setting up Coldfusion is pretty easy, but he has a mac, which I know 
nothing about…the database is MS ACCESS (I know…) and  I was just hoping to 
avoid getting him to do that and get all the Coldfusion code over to him and 
get the database working….

 

Is it possible to just set up the compiler/debugger in Flex builder to use the 
remote Coldfusion setup I have already?  It would seem like that would be a 
better alternative, especially with more than one person…always compiling and 
debugging against the same cfc’s and data.

 

I have no real basis for this thought, however, having said that, it would seem 
I should be able to set this all up for my remote server… do the ColdFusion 
root (which is the same as my local set up) and WebRoot (which is the same as 
my local set up) and just somehow change the rootUrl to point to my remote 
server…and maybe also have to put a cross domain file (can’t remember the right 
name) on my remote server. 

 

However, it seems whatever combination I try, fails…

 

This might not be possible…but it seems it should be.

 

Thanks for your time,

 

Mark

The thing to remember with ColdFusion is that when defining channels and

ColdFusion installation location for web roots, etc... not the IIS locations 
even if you're serving the web content from your inetpub directory.

 

To get the CF debugging setup, you need to define a server instance inside 
ColdFusion builder and then define your CF project to use that server... you 
then "Run" your CF project in Debug mode to kick off the debugging breakpoints 
you put into the CF code will get caught as the CF content is called and run

Re: [flexcoders] Debug Woes - Redux

[mark . jonkman]

Not sure if this is already covered, but you could set your web server to 
include no cache headers so all your files are automatically reloaded every 
time. This prevents the issue of getting an old file. Tomcat might be a bit 
difficult to add the headers as it only has rudimentary page serving 
capabilities as it is meant to be run behind either a standard Apache webserver 
or other webserver such as IIS that is serving up actual static pages/elements. 
I tend to use IE as my debug environment for the simple purpose that it 
launches a new window each time and when you terminate debugging it 
automatically closes that window. No effort to close window manually (unless 
you want to set location and size of window - IE remembers last position and 
size when launching). I use firefox for my general browser. Besides the active 
X version of the debug player tends to be much easier to work with then the 
plugin version which has a tendency to crash on occassion resulting in force 
closing.

[flexcoders] Re: Flex alternatives

[Mark]

I work on a very large flex application that runs within a web page.  Most of 
the functionality is built within the flex application, but it does  
communicate to the server to get data and post results.

I'm in the process of moving all this to a combination of restful web services 
written in C# and Javascript on the client.  For the client my plan is to use 
Dojo.  Moving a lot of code to javascript scares me since it's not as 
structured as actionscript or other compiled languages, but I really see no 
other choice.

The main point I want to make is that I love Flex.  I love how you can write an 
application to embed in a web page, then take that same code, put an air 
wrapper around it and have it run on mulitple OSes as a stand alone application 
with very little work, and believe it or not, it actually works everywhere.

The unfortunate thing is that for web based applications, if you want to 
support the IPAD, and your application needs to be embeded in a webpage, you're 
screwed.  I work for a major publisher that supplies colleges and high schools 
web based course management systems and we are getting a lot of pressure to 
have our stuff work on IPADs.

For this reason alone, we need to convert to HTML5 and javascript.  The main 
reason I'm not considering the ZKoss is that my group is a windows group.  We 
have windows servers and are heavily invested in .Net.  I admit the ZKoss stuff 
looks nice, but for us, it's really not an option.

IMO, the bottom line is that the IPAD is killing Flex, and unless you're just 
writing stand alone applications, you should stop using Flex.  It's a shame 
it's come to this though.

Re: [flexcoders] AIR Application with multiple views

Subject: [flexcoders] AIR Application with multiple views 

We have a pretty heavyweight AIR application. Now we are expanding our product 
and I need to deliver a lightweight version of our application depending on 
which user logs in. So depending on the user's permissions they could get the 
heavyweight application (current application) or a lightweight application (new 
application). The new lightweight application doesn't have any UI in common 
with the heavyweight one. It can use the same data model but the view is 
totally different. One is a fullscreen application and the other is going to be 
a small widget. 

I'm contemplating the best way to handle this. Currently my main application 
MXML file is hosting the entire application. I am thinking about refactoring 
this so the primary MXML file is just a splash screen and login screen, and the 
actual "meat" of the application is moved to a separate window. That way I can 
open the appropriate window once I get the user's credentials. This will take 
some refactoring (for example, I can not longer rely on Application.application 
to get the root window, I will have to add some basic window management) but I 
think it's doable. 

I just wanted to get some other opinions from people who have have had 
experience with something like this, to see if there is a better way to do it. 

So, is there a better way to do it? :) 

Thanks

Why not create a simple ANT build script that simply copies your XML files into 
the appropriate directory for you. Then uncheck the copy non-embedded files 
checkbox. Then execute that script when you need to (assuming your XML doesn't 
change every time) or add the script as another builder on the project.

Unfortunately, we can't uncheck this, or our XML files don't get copied. You

That's not really an option for our project. Besides, I doubt it will stop the 
files that get compiled into the swf from also being copied to the debug 
folder. 

I'm really just looking for a way to get it to stop the delete embedded 
files/copy embedded files cycle every time it compiles. This would save a HUGE 
amount of time.

code you host in there allocates a byte array for 5.6GB, that could explain the 
problem..

Re: [flexcoders] Flex Training

[Mark Lapasa]

Why not just google Flex 4 in a Week? It's like free-ninety-nine. I believe
that covers a good breathe of the concepts out there. I don't think there is
much value learning from advanced Flex 3 tactics (with the exception of
those mx components that haven't made it's way into spark).

[flexcoders] looping ArrayCollection

[Mark]

I must be having some crazy brain cramp right now, I'm having a devil of a time 
with getting a loop to work properly.  I have an ArrayCollection that I need to 
get to data a level or two down (root>item>associated>fKey).  When I loop thru 
it it's fine unless there's only one item in there.. then I get an error.  My 
brain is fried.. can anyone tell me what the heck I'm doing here?

Thanks

Original XML:

  
1
23
2



Loop:
for (var i:int = 0; i < stories.length; i++) {
for (var j:int = 0; j < stories[i].associated.fKey.length; j++) 
{
trace(i + "  " + stories[i].associated.fKey[j]);
}
}

Everybody is talking about "learning"  another language.  That's the

RE: [flexcoders] Transfer development from PC to Mac??

[Mark R. Jonkman]

If you haven’t found an easy way to transfer yet, you could try a slightly more 
complex route. If you have access to an SVN repository, just check in the 
project from the PC (share project) and checkout on the Mac -> Import -> 
Project from SVN -> …… Or vice versa.

 

We co-develop on mac and pc and use SVN as our repository and we share projects 
with no issues (ok. Once in a while we hit a small issue if we include any hard 
paths).

 

Even if you don’t normally use SVN its not normally that difficult to setup a 
temporary repository on one of the computers provided they are networked..

If stuffit doesn't work, you can try RAR, it's not entirely a freeware, but you 
can run the evaluation version for as long as you want.

 

Also, I think that 

 

unzip file.zip -d ~/another/folder

 

(You run this in terminal - the CMD in PC terms)

 

will work just fine on any mac OS you may have...

[flexcoders] Re: open source server side push

[Mark]

Yes, WebORB definitely supports data push. We have support for RTMP, short and 
long polling. A licensed version of WebORB does not have any limitations for 
the number of concurrent users. Your limits will arrive from the hardware 
configuration of the architecture of your application.

Also, I'd like to correct the following, as it is incorrect:

>>>>
"I noticed right off the bat that the weborb java version is limited to 5 ip
addresses (unless, of course, you pay). "
<<<<

The 5 IP limitation is only in the "Development mode" of WebORB. That is the 
mode when you do not need any license keys and can use all the features of the 
product for the development purposes. If you need a license, you can get a 
completely free one for the Community Edition, or buy one for the Enterprise 
Edition.

This is where you can apply for a free license for the Community Edition:
http://www.themidnightcoders.com/communityeditionapplication.html

To see a comparison between Community and Enterprise editions, visit this page:

Re: [flexcoders] Compare two datagrids

[Mark Lapasa]

Don't compare two datagrids.
Compare two datasets.

If you need thew view to display what's in common, then you can create your
own Filter function and apply it to the underlying data sets.

Any changes made to the data will be reflected in the view.

I'm assuming you've cleaned all the projects. I tend to do more AS projects

[flexcoders] Re: What's up Adobe?

[Mark A. DeMichele]

I think the new name makes perfect sense.  The current FlexBuilder
doesn't only "build" "flex".  It builds "flash" as well.  When you think
of it, it is truly a "Flash" "Builder".  In fact, before they decided to
change them name, I wondered why they were associating the name with
"Flex" in the first place.  When I started, it was not obvious I could
use it to build a simple flash animations without the flex framework,
which I actually needed to do for a few projects.  I think of it as a
"programmers" tool for making flash "apps" as opposed to an artist's
tool for making pretty animations.

[flexcoders] Re: Adobe pulls Single CPU and 100-user licenses

[Mark]

Jeff,

Back in the days (about 2 years ago) we (Midnight Coders) approached Adobe with 
an idea to create a data management implementation similar to the one in LCDS 
in our .NET product. What we heard back was a big storm of very loud NO-NOs - 
"you guys cannot do that, it will be against our license agreement. There's NO 
way your customers can use fds.swc in conjuction with WebORB for .NET". We had 
no choice but to create an alternative Data Management implementation and in 
result fragment the market. 

I do not think it it just Adobe's lawyers, this goes all the way to the product 
management team and there's very good reason (from their perspective) why that 
licensing term is there

Really wishing Adobe would be more open minded..

Cheers,
Mark

[flexcoders] Loading videos/sound in Flex (web) out of a ByteArray

[Mark]

Hello, 

I am working on a flex project for my job, and we have seem to of hit a road 
block.

we have two parts to our project, one part which is written in AIR that is used 
to create case files, which is really just a zip with a XML file and 'assets', 
as in pictures, text, audio, video, hyperlinks, and whatever else we may want 
to use in the future

The way the zip library we are using works is that we get the individual file 
information out of the zip  by calling a function which returns a ByteArray 
representation of the data

However, our problem is using the limitations of the Flash/Flex Web-browser 
plugin (not air) which does not have any of the file functions, so we cannot 
save the files we extract from the zip to the hard drive, (which we do with the 
AIR portion of the project),  we are forced to keep them as ByteArrays. 

But, we are having problems with a part of our program which previews these 
assets, namely Audio and Video files in the browser, it appears that the 
VideoDisplay and Sound classes do not accept ByteArrays, but only streams or a 
URLbut we cannot give it a URL because we just don't have one, the files 
are in memory as a ByteArray object.

Is there any cool way to convert a ByteArray into a Sound /VideoDisplay that 
anyone knows of? If not, we are going to have to resort to using an external 
php script to do the work of unzipping files on the server, which defeats the 
purpose of having it all in one file anyway.

[Mark Lapasa]

For you svgViewer, have it set to visible = false at the beginning. When 
the svgViewer has finished 100% of what it's doing, have a listener 
already defined waiting for this event. When it fires off, the handler 
will turn visible = true. -mL

You can try

flash.events.Event.DEACTIVATE

which comes out of Application

a new problem arises if the user really shut down the flash player or

Re: [flexcoders] Beginner Questions

[Mark Lapasa]

Most would use ActionScript 3. The Flex Framework add a lot of overhead 
to a highly animated game. The controls weren't made for that type of 
genre of application.

You could use OS Flex but Flex Builder's built-in's will save you clicks 
in the long run and you just get things done out faster, which means 
gratification faster.

It all depends on the type of game you are developing whether vector or 
bitmap. Vectors can give you an advantage in portable file size and 
smooth scaling. Bitmaps can give you control as a static canvas but you 
pay the price in large file sizes. Code-wise, your graphics is wrapped 
by a container, you move the container. Code doesn't really care so much 
what's in the container.

You should also consider the growing libraries out there for 
actionscript like Papervision 3d and AS3 Data Structures For Game 
Developers.

You could also recycle your C/C++ expertise via Alchemy

Re: [flexcoders] Re: Need help Combobox label property

[Mark Lapasa]

You got a questionable data model if the country names are not bundled 
with the same SOAP msg that has your country codes.

1) Is your Flex binary supposed to have hardcoded all the country names?
2) What happens if you have the server-side return you a country code 
that the client does not expect?

It seems to me that it is half dynamic.

Wouldn't your life be easier if the java WS just told you both the combo 
box label and the underlying country code, instead of just the country code?


Anyways, if you can't do anything about it and you have to work with 
what you got, another approach (in line with Tracy's idea) is to have a 
Dictionary whose keys are your country code and values are country 
names. The next fancy step would be the cache the dictionary into a 
SharedObject so that the next time the user uses the combo box control, 
previously known country code and country name pairs will be available 
to the user. Just some thoughts

Re: [flexcoders] Need help Combobox label property

look at combo boxes labelfunction
the function will then inspect the countrycode and you'll have a nasty 
switch statement that will output the correct country name

Re: [flexcoders] Re: create class on the fly

[mark . jonkman]

Hi 

Somewhere you will need to write an .as file and compile it into a swf in order 
to use it at runtime. Flash can't compile an .as file or a string at runtime. 

You can however, compile any number of .as files into a Flex Library project, 
load that library at runtime then using getDefinitionByName retrieve the class 
reference then instantiate it. 

One way I do this in a semi automated way is as follows: 

Create a series of Flex Library projects in Flex Builder or Flash Builder. 
Create the appropriate classes in each of the library projects. 
Create one Flex project and name it something like Library_Builder. 
Link all the Flex Library projects against it as RSLs 
Set each RSL to auto-extract and give it a directory and filename to 
autoextract into. 
Then I compile that one project to recompile all my libraries and when I need 
the runtime (vs. debug versions) I just do a release build. 

I never post the Library_Builder project to my site, it has no code in it, it 
simply serves to build the debug and release versions of my libraries en-masse 
without having to do a lot of jumping through hoops. I actually configure the 
Library_Builder to build itself into the debug folder of my real project and 
the release into the release folder of my real project. I just skip posting it 
and even if it gets posted by accident, its totally useless. One could link a 
folder in Flex Builder from one project to another, but I like to check my 
folders into SVN and it gets checked out to the server so its easier to do it 
into my main project. 

You can have as many library projects as you want to break things into 
"modular" libraries to load on demand at runtime into your main project. To 
have a lot of one class library projects would be rather a nightmare to deal 
with, but grouping classes that are used together into the same library project 
is often wiser and less prone to dependency errors. Dependeny errors result if 
your library project needs access to classes in another library and that 
library is linked to as an external library during compile. Then you need to 
make sure the dependencies are resolved by having all necesary libraries 
loaded. I tend to use only a handful of very distinct libraries like this where 
all the dependencies are pretty much resolved internally or can be resolved by 
loading a single common library upfront first. 

I don't have access to the full thread right now so I'm not sure exactly what 
you are doing. But in order to access a class you need a compiled version of 
the class - aka in a swf somewhere. And you need to know the name of the class 
(fully qualified). You need to load the swf at runtime then access the class. 

Sincerely 
Mark R. Jonkman

Does this mean I don't have to create the class as a .as file and compile it 
into the SWF, I can just reference it this way? Then I could add a new class to 
myPackage and tell my app (via db, XML, etc) that there is a new class there to 
load? 

The point to all of this is a dynamic application where an end user can add 
their own tables, and I need classes for those objects so that I can pass them 
back and forth with data messaging.

Re: [flexcoders] Re: create class on the fly

[mark . jonkman]

Hi 

If you load a module that has a pile of classes in it, you can instantiate them 
without having a static reference in your original code. However, you do need 
to be a bit cautious. 

By default, modules load into a child of Application.currentDomain and thus 
aren't as "accessible" as classes loaded directly into 
ApplicationDomain.currentDomain. 

If you want to create a module or code library that you can load and have 
complete access to at runtime as if it's classes were a part of your project 
then you need to create a new LoaderContext using 
ApplicationDomain.currentDomain and use that LoaderContext to load your module. 

Once loaded, you can use a variety of methods to get at the classes. When I do 
this I often have the class names as strings in an XML file that I load so I 
don't need to do any guessing. I simply look up the class name in the xml, then 
use getDefinitionByName(className) as Class and then if that returns a Class I 
simply instantiate that class. But then again I'm loading the library into 
Application.currentDomain because I intend to use it throughout the project and 
have no need to child domain the stuff. 

If you put things into an XML file try to avoid a few things like naming a node 
or attribute "class", I normally use the attribute "class" but as a consequence 
I need to access the attribute using myNode.attribute("class") vs. 
myno...@class since @class will fail because "class" is a reserved word and 
Flex no like that. I'm stuborn and I like to call things what they are, but as 
a consequence I hit the occassional compile error for my stubborness. 

Not sure if that helps you at all. 

Sincerely 
Mark R. Jonkman

If I compile the class as a module, can I then load it in without having to 
statically reference it in my compiled code? I can predict the package name 
based on data from my database ie com.something.somethingelse etc. Then I could 
compile new classes as needed and load them.

[flexcoders] How do I Change Event on a CheckBox

[Mark]

I'd like to run a function whenever a checkbox has changed regardless if the 
user selects/deselects it or if it changes from a different user action (such 
as resetting filters by clicking a button).  I tried using 
calendarCheckbox.addEventListener(Event.CHANGE, changeCBF); but this only works 
from a user interacting with that checkbox.  How can I do this?

Thanks,

"with large datasets, we see a lag in the transport time over our web service.  
For example, we have a data set that returns 5000 rows of 125 columns of

This is exactly one of the reasons to use AMF on the wire. Serialization of

Re: [flexcoders] Flex Builder, Flash Builder, Flash and Catalyst

Hi Bruce 

Flash Builder 4 replaces the product formerly known as Flex Builder. 
Flex know refers solely to the Flex SDK. 

No idea what so ever as to what they are planning on charging.

Subject: [flexcoders] Flex Builder, Flash Builder, Flash and Catalyst 

Hello all, 
I was wondering about a couple things. Is Adobe going to make two separate 
products, Flash Builder 4 (aka Flex Builder) and Flex Builder 4? Maybe I read 
something wrong. Perhaps, Flex 4 is the new SDK and Flash Builder 4 will 
replace Flex 3, so there wouldn't be a Flex Builder 4. 
Then there is Catalyst. Any idea what that will cost when it comes out in it's 
final version? I guess that's a long time away. Anything else that Adobe is 
doing in the area of RIAs?

Hi my XML has been set up pretty basic but it does have a few levels.  This is 
shortend, but it basically looks like this:







































Is there a way to get the advancedDataGrid to display the competencies as well 
as the deliverables in a tree structure?  The childrenField only accpets one.  
How can this be done?  Or do I need to rename some of my XML nodes?

Re: [flexcoders] Re: Need Alternative for enterFrame event (Causing Memory leak )

[mark . jonkman]

Hi Dharmendra 

While you don't have access to JavaScript, would the old school methods still 
work such as setting a Flash variable on the active x control. Back in older 
versions of Flash the only way to communicate between the browser and the 
ActiveX was to use things like setVariable then inside Flash you would have a 
watch expression that watched for changes to that variable, and reacted. The 
variable value could only be a string (I think). Back then we would change the 
value of the variable from outside, have Flash react to the change, reset the 
value of the variable to its "non-set" state. Assuming this would still work, 
when the .NET application regained focus you would tell the ActiveX instance to 
setVariable("focusReceived", "true"); and in Flash it would see that, reset the 
listeners. One word of warning, if your resetting your listeners constantly, 
are you doing anything to remove the old listeners first - if not that may well 
be the source of your memory leak. I used the setVariable method in VB with the 
old Flash active x controls a number of years ago and it worked flawlessly, you 
just have to set it up right to begin with and it was obviously "messier" then 
the ExternalInterface method.

Mark R. Jonkman

Hi Manish, 

Thanks for the suggestion. 

I wish , I could use java script to set the Focus but I do not have luxury of 
Java Script as My application is running as ActiveX control inside dot net

Once the callback broken , communication from Ashokwave lib to swf is not 
possible. 

This is really a serious issue, I need some work around to fix it as I could

Re: [flexcoders] Re: Successive Videos Display

[mark . jonkman]

Flash may be single threaded in terms of ActionScript code execution, but when 
you call something to load, Flash doesn't stay locked down on the load, it 
continues to give a slice of its processing to multiple operations, one at a 
time, stepping through a list of active processes. It even "idles" for a few 
milliseconds and then begins the entire process over again, executing code in 
each movieclip, main timeline, load processes, drawing the screen, breathe and 
repeat (not necessarily in that order). All net operations are handled 
asynchronously, you start it and either check back later if its done or listen 
for an event. So in theory if you had multiple NetStream instances, you could 
begin loading a video in each one, then attach the stream to the Video instance 
when you want to actually view it. I wouldn't necessarily attempt to do to many 
simultaneously, but if you are doing progressive flv you could monitor when the 
first one has finished loading (not playing) and begin loading the next video 
assuming you can anticipate the play order. I haven't done this myself, but in 
theory its plausible and perhaps the only way to do what you want to do. 

Sincerely 
Mark R. Jonkman

Thanks for the suggestion. I have a bit of confusion. What do you mean by "load 
the next one when while one is playing". ActionScript isn't multiothreaded. How 
can it load the next and play the current at the same time. Or did I not follow 
whatyou said correctly?

Perhaps a good way to do this would be to create multiple VideoDisplay 
instances with the autoPlay property set to false. Then you call 
load() on the next one in the queue while the current one is playing. 
When the current one finishes, you swap the new one in place and call 
play() on it (and load the next one).

[flexcoders] popup systemManager not working

[Mark Hosny]

Hey guys,

For some reason when I dispatch a custom event via the pop up, my  
main app isn't receiving the event.


In my main app I have a custom component called search, which  
contains a button to open up a pop window called new member. In my  
pop up I have this:



[Event(name="onSendNewMember",type="com.event.SendNewMember")]


private function submitForm():void
{
newmemberinfo = new NewMemberInfo();
newmemberinfo.HOHlastName = HOHlastName_txt.text;



dispatchEvent(new SendNewMember 
("onSendNewMember",newmemberinfo));

}

Then in my main app

application.systemManager.addEventListener 
("onSendNewMember",onSendNewMember);


private function onSendNewMember(event:SendNewMember):void
{
Alert.show('GOT IT');
}


thanks,

hoz

[flexcoders] Problems with FABridge - bridge is undefined

[Mark Schiavone]

I'm using FABridge for a charting application and am having some big
problems with it.  Many times, the chart will load, but cannot display data
that is being passed in via the bridge.  It seems that Flex can call
JavaScript functions, but JavaScript can't find the bridge in order to
communicate with Flex.I'm currently seeing the issue in FireFox 3 and
not in IE, but the problem is intermittent.  On one implementation of the
code, it will work, but on another, it will not.

My app is complex and requires custom bridge names so that if rendered
multiple times on the same page, they won't bump into each other.  Not sure
if this is causing the issue or not.  Has anyone experienced anything like
this?

Thanks in advance,
Mark

[flexcoders] Re: filter complex arrayCollection

[Mark]

Thanks for the link Ivan...

Although that's very cool stuff I don't believe that's what I'm looking for in 
this case.  I'm really just looking to filter an ArrayCollection that goes 
beyond one level.  I'm having a hard time with this so I'm even wondering if I 
can do it with an ArrayCollection or if I need to use something like 
XMLListCollection.

[flexcoders] filter complex arrayCollection

[Mark]

Is there a way to filter an ArrayCollection of hierarchical data?  So if
I have a structure as I layed out below where I have a number of
projects in my ArrayCollection, how can I filter on delCreationDate
within deliverables/deliverable (there could be multiple deliverables)? 
I've looked around and can't find much on this.  If I can't filter an
ArrayCollection in this way, is there another collection I can use that
will allow me to do this?   Thanks

I assume you want a real-world app to learn by, because it's easier to
learn if you have a proper goal. Right?

These days, Twitter apps are popular for that. It's not too difficult,
and no matter how many are out there, they're never /just/ the way
you'd like them to be, it seems. You could use AIR for that, to have a
proper standalone app that can live in your dock and notify you when
new messages arrive.

Twitter is just an example. It could be any web-based service you use
that has a public API. Or, write a bookmark manager (you can read
Firefox' bookmarks), or a time logger.

[flexcoders] cfc to VO pesky problem

[Mark Hosny]

Hey guys,

I understand how to convert an array from my cfc into an array  
collection, populate a datagrid, and cast a selected Item to a VO. My  
problem is if I'm returning just 1 DB record and want to convert to a  
VO, so I can bind to a form (in other words, skip the populating a  
datagrid with AC part), how do I do this?


I thought I could do something like this:

[Bindable] public var ministry:Ministry;

ministry = event.result as Ministry;

or

var minList:Array = event.result as Array;
ministryList = new ArrayCollection(minList);
ministry = new Ministry();
ministry = ministryList.getItemAt(0) as Ministry;

I'm sure it's something simple I'm missing. Below is my cfc

returntype="array">







SELECT
ministryID,
name,

leader

FROM connectionInfo
			WHERE departmentID = value="#ARGUMENTS.departmentID#">





stMin = structNew();
stMin["_type_"] = 
"backstage.connect.com.services.Ministry";
stMin["ministryID"] = qRead.ministryID;
stMin["name"] = qRead.name;
stMin["leader"] = qRead.leader;

ArrayAppend(ret, duplicate(stMin));






Thanks,

Hoz

Re: [flexcoders] Re: Flash player 10 Debug not recognized in FB3

[mark . jonkman]

Hi Jason 

Sorry I don't have access to the full thread at the moment so pardon me if most 
of my suggestions have already been tried or are irrelevant. 

You would need to run the adobe uninstaller for the Flash plugin and then run 
the appropriate installer for the debug player installer (not the web 
installer). Though I've been successful in running just the debug installer and 
having it overwrite previous installs but I like cleanliness of doing an 
uninstall first. 

For FB3 you also need to make sure that you have I believe FB 3.0.2 in order to 
use FP 10 Debug player properly. Less then that and I was getting a ton 
warnings about not having the debug player. I still occasionally getting FB 3 
reporting back that I don't have a debug player and then totally crashing the 
browser it launched - up to 2 or 3 times a day (Windows IE7, FP 10,0,22,87 
Debug player - FB 3.0.2). Not sure if it will update to 3.0.2 by using the Help 
-> Search for Flex Builder Updates which invokes the adobe updates system that 
updates all adobe software (which I find very annoying) or whether you have to 
download a separate updater from Adobe. 

Flash and I believe Flex Builder also include a folder that contains the both 
the debug and release players so that you have both binaries available. But I 
can't say that they aren't always in synch with the latest debug players that 
you can find on Adobe's site if you search for the latest debug players.

Mark R. Jonkman

OK, thanks, but not really sure what that means or what to do with that 
information. Do you mean I have both the "normal" Flash player 10 installed as 
well as the debugger version of Flash 10? I have run the adobe uninstaller and 
then re-installed with no luck.

RE: [flexcoders] stopping a sevice call mid request

[Mark Easton]

Probably best to code this functionality on server side in your own proxy
which will in turn make the call to the listing service. This "proxy" can
check for multiple calls and handle that anyway you wish.

  I am not sure that you can.  After all, the call is asynchronous, you have
sent it off to some place for handling.  What would such a “stop” do?  Go
the server processing the request and tell it to stop?  I can imagine it
would be possible to code such a behavior into the server process, but the
long running server process would have to continually check for a stop
order.



  Why are you wanting this behavior?

Re: [flexcoders] RemoteObject in AS3 Project

[mark . jonkman]

Hi Nick 

The dependancies really get a bit convoluted due to the localization classes 
that are intertwined for error messages and the like. Literally almost drove me 
to drinking trying to get this stuff to stand by itself - even just the 
ArrayCollection class to stand by itself. 

At best I've ever been able to do is root off of SimpleApplication instead of 
Application. This automatically includes some of the classes that are needed. 
Note: SimpleApplication does not appear as an option in any dropdown list, but 
its there (hidden). In essence it creates a very light "bootstrapped" version 
of the application that doesn't require nor will it allow you to use, any of 
the Flex components if I remember right. However, it *will* allow you Remoting 
standalone. 

If memory serves me right, you have to still be a bit careful in how you 
approach things. In order to use Remoting I believe you will need to specify 
everything manually vs. relying on compile settings. I ran into a problem with 
Remoting not working right when having a complex startup structure, but I was 
relying more on compile settings for the endpoints. At the time that was enough 
to make me abandon things, however later when I got things working with 
Application using settings I loaded manually from an xml file I didn't get a 
chance to go back and test if it would have worked with SimpleApplication. By 
that time I had wasted several days of research and needed to get things 
happening. 

So if I were you and I was attempting to do things I'd start out by doing the 
following: 

a) Create a Flex Application based on Application and figure out and get 
RemoteObject working without using the configuration settings in the project - 
that is do not declare that you are using remoting or any server type. Use as 
few UI components as possible. 
- I don't like MXML very much so I let Flex create the project and its 
main.mxml. I then create my own ActionScript class that extends Application in 
my normal package hiearchy. I then import the package using xmlns into the 
main.mxml and change the class defininition from mx:Application to the new 
namespace:MyApplication. I then ignore the MXML from there on out. 

b) Once a) is working, change out Application with SimpleApplication (same 
package, so just add Simple to the import and extends. Replace any UI 
components with simple things like TextFields and the like. See if it will 
work. 

c) Once your comfortable with a) & b) then I would take the concept and see if 
I could get it to work with the ActionScript project. Or if your like me, I 
stay with the Flex App project as there are a couple of other minor benefits in 
terms of automation and the lack of need to sort out the rest of the references 
to the libraries. SimpleAppication does not base off of a Container like 
Application does. It does bring along some baggage but the baggage depends on 
the amount of the Flex framework you access. 

Not sure if this will help you, but it summarizes how I attempted to approach 
it. Like I said I made some mistakes, and then didn't have time to go back and 
retest so the above might get it to work, might not. But take baby steps in the 
transition from one to the other vs. attempting huge leaps and you might be 
rewarded. 

Also, if you are going ot manually configure things I think I wound up needing 
to use: 

mx.rpc.remoting.mxml.RemoteObject 

and not just RemoteObject. 

sample manual configuration from an XML file 

_remoteObject = new RemoteObject(); 
_remoteObject.source = _configda...@source; 
_remoteObject.destination = pconfigda...@destination; 
_remoteObject.endpoint = pconfigda...@endpoint; 


where the config xml node looks like this: 
(FlourineFX) 
http://{server.name}/Gateway.aspx"; source="Service.ServiceFacade" /> 
or 
(ColdFusion) 
http://{server.name}:{server.port}/flex2gateway/"; 
source="Service.ServiceFacade" />

Mark R. Jonkman

Re: [flexcoders] Re: I want to use Flex Builder 3 to develop Flash Games

[mark . jonkman]

meline for, I 
create a symbol that would represent that timeline and use it instead. 

I hate debugging in Flash itself (the Flex debugger is 10xs better for whatever 
reason that is I don't know - just easier to use, and at least in CS3 didn't 
crash as much). I've been told that the Flash debugger was based on the Flex 
debugger but for whatever reason the Flash team missed the boat on something 
because they don't work the same. Plus you might gain the use of the Flex 
profiler. 

The above workflow works for me, if you use Master symbols to pull in all the 
assets then you have a cleaner way that doesn't require as much effort to 
maintain. You don't have to create swcs for individual assets, just in the 
publish settings check the box that says create swc (it goes by the name of the 
swf and into the same folder and name). Flash needs to see the real classes 
when associating them with Symbols in the library but only the actual symbol 
gets pulled in *if* you use the same src folder in Flex Builder. 

Just *DO NOT* refer to anything in the Flex framework - this is for Game/Flash 
AS only development, the rules change big time the second you want to use 
anything in the Flex framework. 

But there is absolutely no way to update a Flash swf with new code from within 
Flex. You get close using the above and tweaking a bit.

Re: [flexcoders] Can you get the class name of an object?

You can use 

var objectClassName:String = getQualifiedClassName(object); 

If you are using all Flex components, you can use the className property of the 
flex component which returns just the name like "Button". The other method 
above works for any object class.

Hi guys,

I have a check box for each record in Datagrid Column. I used the

Please help me to do this.

RE: [flexcoders] Re: sms with flex and coldfusion

Off topic a little, but 

One of the unique features that bulletinwireless has is "two-way" sms for
which they possess a long standing patent.

Essentially, through their associations with the telcos and gateway
providers, then can control part of the source msisdn and thus use that part
to thread messages. So when a reply comes back, you know which sms it is a
reply to.

RE: [flexcoders] Re: sms with flex and coldfusion

[Mark Easton]

No there is nothing in Flex for sms. I cant say for Cold Fusion.

But, sending and receiving SMS is no big deal if you arre using Email2SMS or
some API.

The other way is to use your own modem and send SMS messages with that - but
you did not want to use a gateway.

I was actually the Development Manager at www.bulletinwireless.co.nz for a
few years, so I know a bit about it.

[flexcoders] How can an SWF read its own metadata tags?

[Mark Carter]

How to read SWF metadata tags (like "title", "publisher" etc) at runtime from
within that SWF?

I use ANT to build the SWF. I manually define metadata like "project name"
etc in a build.properties file. I use these values in ANT to name the SWF
and installer etc and also I can use them to set the metadata tags of the
SWF I'm compiling to.

But when this SWF is running, how can that metadata be accessed?

Or is it better to embed the build.properties in the SWF?

I need this for an About dialog box.

  Just a thought but if you are limited by pixels maybe you can make pixel
represent a subset of data. Then if you can use that subset to test for
outliers at certain deviations you color it differently then a red dot needs
further review yellow dots are not that bad and blue dots are
inconsequential. (hot - cold colors). Each dot would represent a plotable
set of data.

  Definitely will do Doug. Its going to test my flex skills, but I hope to
have done it by the end of next week. It is complicated in that we have a
dashboard that allows the users to see many graphs for all the different
sensors, contact inputs and actuators at the same time - and move them in to
display groups (each display group has its own tab). I am taking the
approach that these "display group" graphs will all be displayed for the
last 24 hours or the last hour (switchable by the user). Then if the user
wants to do further analysis he/she can select the graph to analyse it
further and we will do that in a full size window. That is where we will
apply what is discussed below.

  Graphing actuators and contact inputs is also interesting as they only
have three values - Nan, 0 and 1. I will used a stepped line for those, but
will still need to be massaging data depending on the sample size required
to fit the data into the available x-axis pixels. In this case the client
does not want the sampling to miss any state change activity. Obviously we
cant average the sample data, so for this I am thinking I will plot the
sample entry point and exit point. Then, in another series I will also plot
the number of state changes in the sample. Then the user can slice using the
slider to look at parts of the graph in more detail and thus be able to see
exactly what the activity was.

Hi Maciek,

Thanks for your response. 

Yes I have seen that example and I liked it. We still need to contend,
though, with having 500,000 values to plot for the full graph. Using
standard graphing that takes for ever to plot - in fact I could not get
it to plot. 2000 values seems to the maximum number of points that can
be plotted, or to be exact the number of pixels available on x-axis. So
how can I take 500,000 points and :

1. Producre a graph that as closely as possible retains its shape?
2. Shows exceptional values

If I were to massage the 500,000 points by taking sample of 250 points
and averaging them, then I can miss important detail. I could use a
vertical column graph with floating columns, where I plotted the line
starting at min and ending at max for the plot point.

Furthermore as the user used the slider to look at a smaller portion of
the graph I would still want to plot at maximum pixel detail. That is if
the user uses the slider to look at 1 month then that would allow me to
plot points where each point was calculated from a smaller sample size.

Cheers
Mark

RE: [flexcoders] Charting 1 minute data over 1 year

[Mark Easton]

I like the idea of the separate series for the outlying points. 

With respect to the main graph showing raw data ...I am not sure that would be 
acceptable to the client. Depending on the range selected by the slider the 
main graph would still be limited by available x-axis pixels in terms of what 
it can display. At one extreme the user could user the slider to select the 
whole graph - that dataset is 500,000 points. We could limit the slider to the 
detail that can be displayed in the main graph. But that means that only a 
small slice can be viewed at any one time, and the added user problem of having 
to move two sliders to keep the slice small.

I think if we went this way then when the slider is resposition I would need to 
look at the data population size for that and base on available x-axis pixels 
produce a new dataset to display the top graph. But I believe this would make 
the slider, slow and difficult to use, unless I allowed the sliders to be 
positioned and then the user clicked some button to generate the new graph.

RE: [flexcoders] Charting 1 minute data over 1 year

[Mark Easton]

Hi Maciek,

Thanks for your response. 

Yes I have seen that example and I liked it. We still need to contend, though, 
with having 500,000 values to plot for the full graph. Using standard graphing 
that takes for ever to plot - in fact I could not get it to plot. 2000 values 
seems to the maximum number of points that can be plotted, or to be exact the 
number of pixels available on x-axis. So how can I take 500,000 points and :

1. Producre a graph that as closely as possible retains its shape?
2. Shows exceptional values

If I were to massage the 500,000 points by taking sample of 250 points and 
averaging them, then I can miss important detail. I could use a vertical column 
graph with floating columns, where I plotted the line starting at min and 
ending at max for the plot point.

Furthermore as the user used the slider to look at a smaller portion of the 
graph I would still want to plot at maximum pixel detail. That is if the user 
uses the slider to look at 1 month then that would allow me to plot points 
where each point was calculated from a smaller sample size.

Cheers
Mark

  Hi,

  I am trying to work out how best to produce a chart which allows a user
  to
  make sense of data logged every minute for up to 12 months (ie 524160
  values). To complicate matters the graphs are are presented on a
  dashboard
  where the user can display many graphs at once - so we are not just
  displaying the one graph and the size of the graph will change depending
  on
  how many graphs are being displayed in the dashboard window.

  We are logging sensor data (temperature, current, vibration, humidity,
  wind
  speed etc). Client does not like a month, week, day, hour, minute drill
  down
  scenario - I tried that and it was rejected. He wants a line graph, but
  where we do have to average data would like to some idea of max and mins
  -
  maybe that can be done in point comment. Trouble is if we chart so many
  points then there are too many points for the mouse click to discern.

  Essentially the client would like to see the data always at maximum
  detail
  no matter what period is being looked at. I have read this
  http://www.cynergysystems.com/blogs/page/andrewtrice?entry=visualizing_large
  _data_sets, and am thinking that I will need to proceed in kind and to
  use
  an Image object and set BitmapData pixels directly - depending on how I
  decide to reimplement this thing. Of course I am limited by the number
  of
  pixels available along the x-axis for a given chart size.

  This is complicated as the client would like to zoom on the graph and
  also
  look at time slices. The client would also like to be able to see
  exceptions
  clearly on the graph - for example if there was a vibration spike. Also
  sometimes the sensor might not be operational so we need to see those
  breaks
  in the graph when no data was captured.

  All in all I am finding this a complicated requirement to unravel, as
  some
  of the requirements seem to be nonsensical - eg having a zoom - when the
  client always wants to see maximum detail???

  So, I need to work out a design for this which will best meet the

[flexcoders] Zend_amf and boolean values

[Mark Hage]

Hi,

I am trying to send a boolean from PHP to Flex.
In PHP I query a MySQL database which in a column returns a boolean.
In PHP I have class parameter where this boolean is saved.

I use Zend_AMF to communicate with my Flex app.

In Flex the PHP class is mapped to a AS class, which has the type Boolean
for this var.

Now all values are true, but not in my database.

How can this be? And how can I send the proper boolean variables?

Thanx,
Mark

Re: [flexcoders] Flex Builder debugger problems

[Mark Carter]

I also experience this though it only happens about 5% of the time for me.
I'm debugging my Flex app running in the standalone Flash Player 10.

* Usually, my flex app takes a couple of seconds to launch once the
workspace has finished building.

* About 20% of the time, the flash player window comes up and the app then
takes about 10 seconds to actually start.

* But about 5% of the time, the flash player window comes up and then the
app never actually starts (waiting at least a couple of minutes). If I then
disconnect the debugger, the app then immediately starts as normal.

Its like the debugger is blocking something.

So no need to quit Flex Builder. Just disconnect the debugger.

I also experience this. But its not just between two menu items. It happens

RE: [flexcoders] Best practice for calling asynchronous functions?

[Mark Carter]

For me, the question is: If I use someObj in the same way as my example above
(i.e. assigning it to a local variable), when will someObj get garbage
collected?

Is it (potentially) when the result/fault event is dispatched or could it be
earlier?

Re: [flexcoders] Best practice for calling asynchronous functions?

[Mark Carter]

So are you saying that, in general, anonymous functions should not be used as
listeners?

If its anything like in Java, (once the calling method returned) the
anonymous function would only be referenced by the event dispatcher and so
(assuming weak references are not used) would only be garbage collected when
the event dispatcher is garbage collected. At least, that's how I understand
it.

I posted a question about this a few weeks ago, but didn't get a reply.

I don't quite understand...

Wouldn't any problems before the async token is returned, be thrown as an
exception from the method returning the async token? Therefore the calling
code just needs to catch that exception and handle it.

The only problem with this would be if an event is generated after the async
token is returned and before the responder is added. This would only be an
issue in a multi-threaded environment.

Thanks for that - its roughly what I had in mind - but its good for me to

Maybe I wasn't being clear. I just prefer to keep any ASyncToken code out of
the calling code. Having it inside the implementation is not a problem for
me (other than for the other problems with it discussed in this topic). So,
I don't see it as an alternative - its more of an implementation detail.

My current implementation has something like:

function save(xml:XML, successFunc:Function, failureFunc:Function):void {
var service:HTTPService = new HTTPService();
...
service.addEventListener(ResultEvent.RESULT,
function(evt:ResultEvent):void {
trace("Successfully saved XML");
successFunc();
});
service.send(); // called after the event listeners have been added :)
}

That's it. The successFunc and failureFunc are only scoped to the calling
code's method and so should be garbage collected when the service is garbage
collected.

What I don't know is when the service is garbage collected? I'm assuming not
before the result or fault event is fired!

Re: [flexcoders] Best practice for calling asynchronous functions?

[Mark Carter]

Thanks for all the responses.

I hadn't really looked into the ASyncToken until now. However, for me it
seems that using the ASyncToken would be limited to the implementation of
the, for example, save(XML, Function, Function) method.

The calling code doesn't need to know about it. In my opinion this is neater
than something like:

var asyncToken:ASyncToken = save(xml);
asyncToken.addResponder(...

Also, I don't like adding responders after the call has been made. I know it
works, but still...

Maybe I should start a new topic for this next question, but...

...in my implementation, I create a new HTTPService for each call. Any ideas
how (in)efficient this is?  As you can imagine, it keeps the implementation
much simpler. No need for the ASyncToken. Just add new listeners each time a
call is made. Everything is garbage collected. Oh, hang on, what keeps a
reference to the HTTPService?

[flexcoders] Best practice for calling asynchronous functions?

[Mark Carter]

In my app, I make a wide variety of XML-RPC calls. Now, to avoid having to
add/remove listeners all over the place, I've created a class (facade?) with
functions like:

function save(xml:XML, successFunc:Function, failureFunc:Function):void;
function load(id:String, successFunc:Function, failureFunc:Function):void;

Note, the class' state does not change when any of these functions are
called.

The class makes the necessary XML-RPC call and listens to the appropriate
events before calling the relevant success or failure function. The class
guarantees that either the successFunc or the failureFunc will be called at
some point (but never both).

This makes my calling code very neat:

save(myXML, function(id:String):void {
Alert.show("Successfully saved XML using id: " + id);
// now do the next step
}, function(msg:String):void {
Alert.show("Failed to save because: " + msg);
// now rollback
});

One obvious drawback of this is that its not so easy to add multiple
listeners to, say, the save operation. But, in my situation, I never need
to.

What say you all - good or bad practice?
