Re: [flexcoders] Which AIR SDK to use with Flex?
The main issue is, as suggested, that ASC2.0 is not certified to compile MXML, only AS.

Mark, thanks for the reply. I don't use Flex builder, just Apache ant and the Flex and AIR SDKs. I was able to build the Flex/iOS app with both versions of the 15.0.0.302 SDK in their default configurations, so I guess the one with the new compiler uses the old one by default. (At least from the command line.) I'm going to stick with the SDK without the new compiler though, just to be on the safe side. On Saturday, October 25, 2014 9:39 AM, 'Mark R. Jonkman' mark.jonk...@comcast.netmailto:mark.jonk...@comcast.net [flexcoders] flexcoders@yahoogroups.commailto:flexcoders@yahoogroups.com wrote: 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] getting the sum of values in list datafield.
The code looks mostly ok. I noticed you commented out the addEventListener
calls for COLLECTION_CHANGE. I'll bet it threw an error becuae expenseAr is
null until the RemoteObject returns a result. I would move the
addEventLIstener call to expenseResult() method when you know expenseAr is
valid.

So, in theory, if FlexJS using JQuery isn't fast enough, it probably wasn't going to be fast enough use JQuery either. And that's not a problem for the Apache Flex project. The browser companies know they need to get their JS implementations to work faster and computers and devices are getting faster. It might be a problem now, but may not be in the future. Also note that in many cases JS runs faster than AS. In the JS code we do write for FlexJS we are trying to re-use code as much as possible, which is supposed to take advantage of the JS optimizers. That's why FlexJS is using more composition instead of inheritance since AS doesn't support multiple inheritance. pixel-by-pixel control. If the industry demands it, the browser manufacturers will deliver. It doesn't matter for FlexJS, although it would probably make some things easier or faster.

Re: [flexcoders] Re: Future Scope of Flex
Not sure what you mean by Flash to browser native. I've come across 3 approaches so far: 1. emulate Flash in the browser. Jangaroo and Shumway are examples. Not sure how it is going for them. 2. Emulate the current Flex SDK in JS. One Apache Flex committer is taking this approach. The big question here is that I expect the end result to have lots more JS source code involved than a framework designed for cross-compiling like FlexJS. But maybe the browser and minifiers can make that negligible. 3. FlexJS. This is less about Flash than it is about using MXML and AS to cross compile to JS. FlexJS isn't going to have the same pixel-level control that you got in Flash. Only the Flash emulator folks have a true shot at it.

Dynamic languages use different paradigms than strongly typed languages. In these contexts functional styles and extension through composition are favored over extension through inheritance. But these are all just tools for communication between the dev and the user. The users have chosen a route that no longer needs flex/flash. That is neither good nor bad - it just is. You may dislike parts of technology A and think it's inferior to technology B - but have you considered the notion that possibly you may be trying I hammer nails with a saw? You may dislike that JS does not have the type safety of AS. But if you are relying on type checking you are missing the boat. The compiler can't check if your logic is bad. It can only check that something like tab a is in slot b. You still have to unit test. All the skills you bring to solve a problem are only marginally helped by the compiler bitching that a class does not have a method to support an interface. There is nothing inherently bad about prototypical inheritance as opposed to class based inheritance. As a matter of fact you typically don't need to use inheritance in JS. Tell me - is it cleaner to devolve functionality into representations that can be decorated onto any object - and you test the functionality itself? Or to HAVE to inherit from class A in order to get the features if class A? You can't do multiple inheritance in AS - so you have to hack around with interfaces and utils or you must repeat yourself. In JS - just decorate what you need with what you need it to do. It's all good bro. I'm just saying that as a seasoned flex dev that feared moving to JS - in my experience - it was an easy transition. But whatever. Have a great day!

Re: [flexcoders] Re: Future Scope of Flex
I'm going to ignore your brush fire topic, but I will address two other points: juice under the hood. That is a concern for trying to emulate Flash or the current Flex SDK in JS since that is quite a bit of code. But for FlexJS, if you look at the prototype of the JQuery wrapping, it is a thin layer written to implement whatever was needed to implement an AS emulation of JQuery. So, in theory, if FlexJS using JQuery isn't fast enough, it probably wasn't going to be fast enough use JQuery either. And that's not a problem for the Apache Flex project. The browser companies know they need to get their JS implementations to work faster and computers and devices are getting faster. It might be a problem now, but may not be in the future. Also note that in many cases JS runs faster than AS. In the JS code we do write for FlexJS we are trying to re-use code as much as possible, which is supposed to take advantage of the JS optimizers. That's why FlexJS is using more composition instead of inheritance since AS doesn't support multiple inheritance. pixel-by-pixel control. If the industry demands it, the browser manufacturers will deliver. It doesn't matter for FlexJS, although it would probably make some things easier or faster. Already, we've seen significant convergence towards standards in the main browsers (IE, FF, Chrome, Android, IOS). Compare what we have today vs back in IE6 or even IE8. -Alex From: danielpr...@yahoo.commailto:danielpr...@yahoo.com [flexcoders] flexcoders@yahoogroups.commailto:flexcoders@yahoogroups.com Reply-To: flexcoders@yahoogroups.commailto:flexcoders@yahoogroups.com flexcoders@yahoogroups.commailto:flexcoders@yahoogroups.com Date: Tuesday, August 19, 2014 12:05 PM To: flexcoders@yahoogroups.commailto:flexcoders@yahoogroups.com flexcoders@yahoogroups.commailto:flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Future Scope of Flex I certainly wish you the best with the javascript implementation. But have to admit to strong doubts about it. No matter how many hoops you put yourself through you are still working without many fundamentals of advanced programming. There just isn't the juice under the hood, maybe with parallel processing, but then we are getting close to a million monkeys banging on typewriters til they eventually produce a novel aren't we? I think the latest ie browser brought flash into the browser as a native element not a plug in. Like it or not you got it. I was stunned to hear it being done by MS, but its a brilliant way to bring about a correction to the market hysteria which dominated after Job's death, and Adobe's stupid response. Eventually the industry will demand pixel by pixel interface control, there just is no substitute equal to it by definition. After all the burning at the stake stuff, it will probably be called shadow o! r something, not flash, but a rose by any other name. At the risk of creating a never ending brush fire (oh what the hey its fun sometimes), I wonder if some of the jump on flash and pummel it hysteria had an unacknowledged element of gay bashing. Adobe, deserve it or not, like it or not, had quite a reputation. There was one advocate, I think it was in RTMP networking videos, that would insert short clips of himself getting back ended after about 45 minutes of mind numbing, real high end, discussion. I thought it was funny as hell, removed the glaze from your eyes, and dropped your jaw the first time you saw it, but i think others were not so amused. (Hey, Kiddies certainly aren't going to get that far into one of these unless they are enrolling at Harvard at 12 or something, and I survived the experience, and found the fast forward button). I think the bent over man statue in front of the offices also h! elped with the rep issue. BUT WHO CARES ! Credit where credit ! is due. There were some of the most brilliant programmers with some of the greatest contributions by software developers ever. We have witnessed a modern equivalent of the Salem Witch trials on this one for whatever reasons, and the amusing part is that we actually think we are advanced beyond that. Dan Pride P.S.

Re: [flexcoders] Re: Future Scope of Flex
Well, I don't know if Flash will return to being the solution for UI design. With all of the various mobile browsers, I don't know if Flash will be able to run in all of them. But Flex, on the other hand, could. That's what I'm trying to make happen with FlexJS. FlexJS won't control every pixel like you could in Flash (at least, certainly not early versions), but it should provide the other benefits that folks have found missing, mainly in terms of developer productivity. Yes, Flex isn't as popular as it was before Adobe donated it to Apache. Adobe was spending serious money on getting folks to use Flex. But every day, some other product or idea goes viral without million-dollar marketing schemes. So, if you like Flex, take a look at FlexJS and tell us on the Apache Flex dev list (d...@flex.apache.org) what it needs before you'll start recommending it to others such that it can go viral. IOW, you have to do your own marketing if you want to see more Flex jobs, and you have to help shape Flex and/or FlexJS into something worth marketing. No big company is going to do that for you. FlexJS isn't out to compete against HTML5. In fact, it is simply out to leverage it. As I've been working on FlexJS and talking to Flex folks who are now developing in some JS framework, it is becoming clear to me that any application developer using any framework is really just attaching components together. There is a longer version of what I'm about to write on the Apache Flex LinkedIn discussion group, but basically, the problem with JS is that you can attach anything to anything. Newer languages (TypeScript, DART) have constructs to try to catch those mistakes. ActionScript can do an even better job, especially for really big apps. And MXML gives you a schematic of your components. These days, I'm hoping to find folks who can help those of us working on FlexJS prove that AS and MXML can make you more proficient at attaching nearly any JS framework's components together. Then someday, it won't matter what JS framework your client wants to use, you'll use MXML and ActionScript to assemble that JS framework's components into an application and make fewer mistakes along the way. But that someday will come sooner if folks can contribute their time and energy to the project.

They climbed mount everest to the pinnacle of human interface design and did it in a universally accessible way. At the bottom line if you can't mathematically relate every single pixel on the screen to every other one, over time, you are by definition inferior to flash. While I am currently working in Php/Mysql/ with Ajax on top due to the nature of the project (absolute universal access), I think there is still hope. More are taking flash to the browser native. Very smart move. If the standards are there it will in time inevitably dominate. To save face it will probably be called some great new tech called bonzoshow or something :) Everybody literally freaked out at jobs' dying statement, jumped on the it won't run mobile and like a herd of lemmings everybody dove for the exits. Well mobile was si! ngle core then its quad and more now. Flash was and will be again I think a universal solution to absolutely superior user interface design. Pixel by Pixel over time.

How do you turn on -keep-generated-actionscript using ant? I think

Re: [flexcoders] Original application files lost
It is painful but theoretically possible to reconstruct MXML from the generated AS. It is also possible to get MXMLC to build a SWF from the generated AS, but there are some downstream issues: If you ever change this code and it requires changes to generated code like CSS, the compiler will not do the right thing. Therefore it is best to try to get back to MXML. In your original post, you said that file recovery tools found older versions of files. I'm suggesting running these older files through MXMLC with -keep–generated-actionscript and comparing the results with what the decompiler saw in the final version. The differences should show you what you need to modify in the older versions to bring them up to current.

I never kept the generated actionscript files because (obviously incorrectly) I thought my version control and backup routines were solid. So there's nothing there to compare.

That makes no difference. I did notice that VerticalLayout/ always
virtualises regardless of whether useVirtualLayout is true or false.
It looks like TileLayout/ never virtualises, so I suspect it's a bug, but I
haven't had a chance to look into how layouts work to confirm this.

Subject: [flexcoders] Whay are too many itemrenderers being created?
I'm using Flex 4.11 with Air 4.0 to create a mobile app.
I have a spark list with a custom mxml itemRenderer. Only 4 instances will be
visible in the list. The dataprovider is initially empty.
When I assign the array collection with an array of 147 items, I get 147 traces
on dataChange event and on the render event. I traced out the value of 'this'
and I get 147 unique objects.
I was under the impression that only 4 instances of the itemRenderer will be
created and get reused as I scroll through the list.
What have I overlooked?

Re: [flexcoders] Function from string?
Both Array and Object support [] property access. Regarding converting a String to a Function: AS is compiled, not interpreted, so only strings that have been compiled into functions can be run. You can fill an object or array full of functions and choose one at runtime, but that is not the same as constructing a string at runtime and trying to run it. Eval() will do that in JS, but there is no AS equivalent. Some options are: 1) There are some AS3 eval() functions in third-party libraries. But they are unlikely to be fast. 2) You can send the string to a server, compile it into a SWF and load that SWF and run it. 3) If the function doesn't require much information from the rest of the app, you could write the string to JS and call eval on it via ExternalInterface -Alex On 11/6/13 2:02 PM, A.

Re: [flexcoders] Nested TabNabvigator/Repeater error
So if I understand correctly, clicking on some nested Tab changes some other
ViewStack's selectedIndex. If that's correct, try subclassing the ViewStack's
selectedIndex setter so you can set a breakpoint and catch when only that
ViewStack is changed. Then the call stack should contain some good clues.

[Attachment(s) from Tom McNeer included below]
I've finally had time to check this out a little further.
As a reminder, I'm creating nested TabNavigator elements dynamically. I avoided
using a Repeater and attached a CollectionChange event listener to the
ArrayCollection that is the main data provider. The function called by the
listener walks through the structure, creating TabNavigators with VBox
children, and at the bottom level, a custom component (DocDataGrid) that is a
VBox which wraps a DataGrid.
The problem is that a click on a tab in the lowest-level TabNavigator doesn't
display the selected child. Rather, it sends the user several levels back up
the component tree.
I've followed the click through TabBars and NavBars and Buttons till there's a
click event fired where I can't determine what's supposed to hear the click.
The selectedIndex appears correct through each level in the inheritance, but
then the process fails.
I've even added some hack-y invalidateDisplayList() calls in hopes that they
might have an effect.
I'm including the code that creates the elements, along with some screen shots
that I hope will better explain what's going on.
If you have time to look them over, and if you see where I'm going wrong, I
would certainly appreciate any pointers.
Thanks very much in advance.

Re: [flexcoders] Nested TabNabvigator/Repeater error
Probably best to not use repeater.
In the AS version, I would guess there are relatively few ways to switch to a
different screen. If you put a breakpoint on code that does that, does it get
hit and will the stack info show you how it got there?
You might want to build out a simpler re-construction of this problem in a new
Flex project so less of your other code can be run accidentally.
The TabBar children should just be Tabs that dispatch events. The logic that
responds to the change event should be the main concern.

Subject: [flexcoders] Nested TabNabvigator/Repeater error
Hi,
I am trying to create nested TabNavigators which are built dynamically from
server data. The top TabNavigator is static. Its children are created by a
Repeater. Within each Repeater's child (VBox), another TabNavigator is created,
and a second Repeater creates the children of the TabNavigator.
This is a revision of a old application, so it's using a 3.6 SDK.
The top level tabs represent types of Documents. The second level of tabs
represent subtypes. And each time this area is accessed, there will be
different trees of types/subtype/documents.
The process throws an error intermittently as the elements are created:
RangeError: Error #2006: The supplied index is out of bounds.

to select a tab that does not exist. But I have no clue what to do about it.

I have also tried creating the elements in ActionScript, to bypass the Repeater

properly (by appear, I mean visually.) However, when a tab on the second
level (the subtypes) is clicked, rather than the selected chlid appearing, the
user is switched to an entirely different screen - completely away from the
Documents area.
I don't know why the click is taking me away from the screen, but as I walk
through the debugging, it appears that while the TabNavigator children are
created correctly, the children of its associated TabBar are not. Here's the
ActionScript, which is fired by a CollectionChangeEvent listener on the
ArrayCollection which contains the Document data:
private function buildUI(e:CollectionEvent):void{
clearTabs();
for(var i:int=0;iacCaseDocuments.length;i++){
var arSubtypes:Array = acCaseDocuments[i
Re: [flexcoders] Automation and Application Domains
A class's identifier is only as unique as its fully qualified name. You can
think of an ApplicationDomain as an Object with slots for each class as in:
var appdom:Object = {
flash.display.DisplayObject : flash.display.DisplayObject;
mx.core.UIComponent: mx.core.UIComponent;
}
with the exception that, once a slot is set, you can't overwrite it:
first-in-wins. If two separate SWFs supply different definitions the second
one will lose out and that can cause issues with code that depends on the lost
definition. That is baked into the runtime.
What is also baked into the runtime is a lack of an API to take an object and
find its ApplicationDomain. This makes it impossible to write a universal,
works-everywhere, get the class definition for this object.
That said, Flex has some infrastructure to allow a main Flex SWF to find the
ApplicationDomain of a child Flex SWF (but not any non-Flex child SWF) and
therefore take an object and find its ApplicationDomain and thus its class
definition. Automated Testing code could have leveraged this infrastructure,
but apparently didn't. Not sure why, probably because there is no official
documentation on how to do that, and maybe because it would fail for non-Flex
SWFs.

RIAtest has a component 'inspector', which shows the component tree. If my UI

inspector (and events from manipulating it never get received).
When I raised a ticket against it (and asked if there were some API that I

Subject: [flexcoders] Automation and Application Domains
We are using RIAtest, which uses flex automation to test some applications.
Reading the flex documentation, it contains the following:
Testing applications that load external libraries
... A library that is loaded at run time (including run-time shared libraries
(RSLs)) must be loaded into the ApplicationDomain of the loading application.
If the SWF file used in the application is loaded in a different application
domain, automated testing record and playback will not function properly.
This is particularly inconvenient for us; we load UI controls into separate
ApplicationDomains (all children of ApplicationDomain.currentDomain) because
they can have conflicting classnames, and this allows each form to be generated
in isolation, and they cannot interfere with each other. The thought of having
to refactor hundreds of classes is not appealing.
This seems to prevent RIAtest's inspector from finding child controls sourced
from that loader.
Is there any way around this restriction, perhaps by implementing some kind of
delegate class, or overriding

Re: [flexcoders] UIFTETextField - randomly disappearing lines
Yeah, a test case would need UIFTETextField and more than one instance of it in
order to fool the recycler. It might require common text or textflow snippets.
I don't remember how the recycler remembers what can be recycled.
It is fine to switch the text display widget at runtime, but realize that means
more testing, slightly different glyph positions, and different performance and
memory utilization.

Subject: Re: [flexcoders] UIFTETextField - randomly disappearing lines
The odd thing is, the bug wouldn't manifest in a small test app that I wrote
for the purpose of testing possible workarounds. In that app, the text
displayed correctly every single time.
I just did some checking, and this behavior wasn't observed (although it might
have been happening unobserved) until after we began compiling the app with
this:
mx|Label {
textFieldClass:ClassReference(mx.core.UIFTETextField);
}
That was needed to get Arabic text rendering properly. That means that the
number of UIFTETextFields that the app was creating had increased dramatically.
I put some tracing code in FTETextField.createTextLinesFromTextBlock() and
noticed that it was getting called numerous times in the main app, prior to
where the bug occurred, but not so much in the small app prior to where the bug
should have occurred. It makes sense that the recycler was the culprit. In the
main app the pool of recycled TextLines was probably large, whereas in the
small app it might have been empty, therefore no recycling was occurring to gum
things up.
I'm thinking now of having a switch in the app that the small (but important)
fraction of our Arabic-speaking users could use that would, at runtime rather
than compile time, set the textFieldClass style of mx.controls.Label to
UIFTETextField and disable TextLine recycling, while for everyone else, the old
textFieldClass and TextLine recycling would be used. Do you see any potential
problems with that approach?

Hi
When errorString of the component is any value(ex 'Enter the value') then the
borderColor of the component changes to 'red'. But when you make the
errorString= it does not change the borderColor of the component back for the
first time.
It change when the control lose focus.
How can we make the border color to original when using errorString= for the
first time even the control does not loose focus.
I have attached sample of the problem.

Re: [flexcoders] Flash Builder project to HTML5

Re: [flexcoders] Re: Flex alternatives
Looks like Mike Chambers is responding on that thread. He is a better person to ask than me. Even though I work for Adobe, my main focus is on Apache Flex. I barely keep up with the plans and goals of the other teams, even the Flash Runtime, because at this time, Apache Flex isn’t counting on any new awesome features from Flash itself. Apache Flex is looking at publishing Flex apps for HTML5. One approach is described here: https://cwiki.apache.org/confluence/display/FLEX/Alex%27s+FlexJS+Prototype Now, IMO, Flex apps are quite different from other Flash swfs, especially those that are timeline driven, so Apache Flex isn’t going to be the solution for everyone.

John On 20/12/2012 05:50, Alex Harui wrote: Re: [flexcoders] Re: Flex alternatives Well, there are several pieces. ActionScript is a language. It is really only the dozen classes or so in the “top-level” in the ASDoc. String, int, RegEx, Array, Vector, a few functions like unescape, etc, plus a bunch of keywords and stuff like “var”, “class”, plus a grammar of how you put it all together. It hasn’t changed much in years, other than the addition of Vector. There are no plans to improve on its specification by adding things it is missing compared to other languages like Java such as method overloading, or mutiple inheritance. Instead, Adobe is tossing out the whole specification and developing a next-generation of ActionScript. It will have some of the same things you see in the current ActionScript, but there will be new keywords and grammar. The goal is to give up on backward compatibility in order to get significant speed improvements by making the language easier to execute at runtime. ActionScript currently only runs in a Virtual Machine embedded in the FlashPlayer or AIR. Both runtimes provide additional APIs that allow you to draw stuff and get network i/o, etc. The current APIs use ActionScript 3 syntax and are focused primarily on Sprites, Shapes and MovieClips on a display list. New features were added in every major release. Now, Adobe is working on embedding a new Virtual Machine that runs the next-generation ActionScript in the FlashPlayer and AIR. The focus is on gaming, and a new set of APIs that talk to a 3d rendering engine is being devloped in the next-generation ActionScript syntax. There will be no support for the old Sprites/Shapes/MovieClips and display list. However, the old virtual machine that runs ActionScript 3 will continue to be embedded in the FlashPlayer and AIR that run on tradtional desktops/laptops. I would not expect it to be co-existent on mobile versions of AIR because the new focus is on the captive runtime workflow where you pre-process your ActionScript code and the runtime libraries into a device-dependent executable. So, given all of that, you can continue to deliver ActionScript 3 content in AIR or FlashPlayer on desktops/laptops “forever”. And unless you have heard otherwise from the PDF team, they probably won’t eliminate support for Flash in PDF on desktop/laptops soon. I think Apache Flex exists because folks have found the Flex workflow easy and productive and also safe because it uses structured programming, and former Flex customers are now pitching in to continue to evolve Flex as much as we can given the constraints of the current environment. The problem for many is that, because Adobe is not evolving the ActionScript 3 language, VM and runtime APIs related to it, folks see it as a dead end and no longer want to develop apps on it. I can see their point, but there is a reason why DOS is still around on some custom handheld devices: it works, it is well known, and has a small footprint for a constrained environment. Flash/AIR and Flex on ActionScript3 continue to be excellent ways to create apps quickly, but it has been difficult to convince customers to stick with it. Anyway, so far, the most interest in Apache Flex seems to be around trying to leverage the Flex workflow to create apps that run on the HTML/CSS/JS stack (without Flash). It will have growing pains for sure, but to me, a question about CPU load is premature. There is 1000’s of people from all over the world working on improving the runtime environment for HTML/CSS/JS. They have made significant advances in the past several years and I don’t see a cap on it. So any pain points you experience now are likely to be solved in the near future. If you can continue to use Flash/AIR and let others suffer through the growing pains, consider yourself lucky. Otherwise, put on some pads and join the battle.

Re: [flexcoders] Re: filtering an array collection using 2 or 3 textinputs
It looks like there is more work going on here than necessary. There should be
no need to loop through the filteredArr and add and remove things. You should
be able to set the source or list property of the filteredAr to the source,
toArray or list of archiveAr and maybe apply the same filter. It depends a bit
on what you want to share, if anything.
Anyway, regarding the filter function, since you already are filtering based on
generalSearch.text, I don’t see why you can’t add other logic to further test
on someOtherTextField.text.

Re: [flexcoders] Equivalent of editorUsesEnterKey in spark
Hmm, that looks like a bug. Feel free to file it. You should be able to call stopPropagation. The code looks like it is listening to the renderer and the TextArea should be a child so if you cancel it before it bubbles up to the renderer it should work.

Jerry,
I think your issue is the opening brace at line 6 (right after case
Const.ALERT_LIST_RETRIEVED:) and the closing brace at line 32 (right after the
break statement)... the code block for a case statement in ActionScript is
typically not enclosed in braces (perhaps it is even illegal, I'm not sure).
Instead, the code is delimited by the case statement itself and the break.
Either way, your closing brace at line 32 overlaps your break statement at line
31. I suggest removing those two braces or at least moving the closing brace
above the break.

Re: [flexcoders] Frustrations with the profiler - analyzing memory usage.
I have never seen the localconnection hack fail to GC everything, but it has
been over a year since I was last in the profiler, so maybe more recent players
don’t GC everything, but I would be surprised if that was the case. That’s
because the LC hack wasn’t supposed to GC everything, but once we discovered it
did, the FP team felt like they couldn’t change that behavior.
I have seen different player versions cause the profiler to report things as
being around when they aren’t or have it seem like the GC button in the
profiler doesn’t work, but we tend to get that resolved for each new FB
version. Then newer players come along and it seems to go funky again. That’s
why you should make sure you are using the right player for your FB version.
I have never seen weak references not work correctly, so you probably don’t
need to chase paths beyond weak references.
EmbeddedFonts are not leaking per-se. They are sticking around because a
display object that uses embedded fonts is stuck. I usually look for big
things (views/containers/navigators for example). A common workflow for me is
to exercise the app, take a memory snapshot, exercise the app some more, take
another snapshot, sort both snapshots alphabetically, and manually compare the
number of live instances. LoiteringObjects can show you false positives in
some scenarios so I often do manual compares. If the number of big things is
increasing, I look there first. Of course, it could be a child that is stuck
because children reference their parents. And maybe you’ll get lucky and see
that timers or intervals are increasing.

Thanks for that - that's very helpful information.
I'm getting dragged into diagnosis because on very low-spec machines our app is
tending to eat memory causing it to heavily slow down. I've managed to diagnose
some of these (use of setTimeout, Bindings that never go away) which is liable
to help hugely.
What I'm having difficulty in is determining what things in the profiler are
genuine leaks, and what things are things the GC will eventually get to as
they're weak references (I do the System.gc() and new
LocalConnection().connect('foo'); tricks beforehand, but they don't feel like
they're reliable. It's a shame there isn't a
System.reallyreallyfullGCandIDontCareHowLongItTakes() )
A good example is mx.core:EmbeddedFont. When the app is in use, this number
doubles. So I analyse an instance, and find only 1 path - which it states as
simply mx.core:EmbeddedFont (1 Path), GC Root=YES and allocated in
mx.core:EmbeddedFontRegistry:GetAssociatedModuleFactory().
What I believe that's telling me is that the reference is there because of the
static EmbeddedFontRegistry in EmbeddedFont, and it's being stored in that
registry in a cache (cachedFontsForObjects) - which is a weak dictionary.
My gut instinct at this point is this is irrelevant, it'll get GCed
eventually. Two things strike me though
- I'm guessing that it's in that dictionary as the object reference view
stops at the EmbeddedFont, which seems a shame. That makes it difficult in any
code that's pretty complex
- I'm guessing it'll be GCed. But I wonder now if all those things will be
GCed eventually. Why didn't the 'invoke GC' parts actually cause it to be
collected..

private function set _y(value:int):void

__y = value;
dispatchEvent(new Event(“_yChanged”));

I was suprised that you were binding a private variable - that only

I don't know the context of this, but if you had a setter, you might be

I have to say that _y is a bit confusing since y is the natural public

On desktops/laptops, I will be surprised if you lose the ability to view SWFs. I can’t imagine you are the only person to leverage SWFs in PDF and I would expect major backlash if that was to stop working. But the question for you is, in the future will your customers be using desktop/laptops? In the home, tablets are becoming all the rage. This is also true in some upper executive ranks. Tablets may not support SWF in PDF. There aren’t separate VMs for AIR vs Web. AIR is a delivery package of the same AS VM that you get with the FlashPlayer but with some extensions and the ability to hook into the OS, so I don’t quite know how to answer your questions. Both the current AS VM and AS Next VM use JIT to convert AS byte code to machine code at runtime. For mobile apps you have to pre-process the entire SWF and the AIR runtime into a single machine-dependent package. PDF is using a special player but I think that, even if that player does not stay in sync with Flash Player Next, it doesn’t matter to you. It should still run your content. So, I think the big question is what kind of devices your customers will be using. I think Adobe will support legacy content on desktop/laptops for a long time. -Alex On 12/23/12 10:43 AM, John McCormack j...@easypeasy.co.uk wrote: That is a very interesting diagram showing a way forward for Flex users.

On that subject, will later FlashPlayers have separate Virtual Machines for: (1) interpreting AIR (legacy) and (2) Browser (legacy) as well as (3) new code which is CPU dependent machine code? I understand that PDFs have their own built-in player and, according to Dave Merchant on Acrobat.com, we don't know what tje future of that might be.

To not allow existing SWFs to play where they currently play would “break the web” and Adobe has no interest in doing that. The next generation of AS is supposed to be easy to migrate to if you just want to get your code to run, but there is a chance that to fully leverage the performance benefits of the new language you will have to learn some new constructs and refactor existing code.

John On 20/12/2012 05:50, Alex Harui wrote: Re: [flexcoders] Re: Flex alternatives Well, there are several pieces. ActionScript is a language. It is really only the dozen classes or so in the “top-level” in the ASDoc. String, int, RegEx, Array, Vector, a few functions like unescape, etc, plus a bunch of keywords and stuff like “var”, “class”, plus a grammar of how you put it all together. It hasn’t changed much in years, other than the addition of Vector. There are no plans to improve on its specification by adding things it is missing compared to other languages like Java such as method overloading, or mutiple inheritance. Instead, Adobe is tossing out the whole specification and developing a next-generation of ActionScript. It will have some of the same things you see in the current ActionScript, but there will be new keywords and grammar. The goal is to give up on backward compatibility in order to get significant speed improvements by making the language easier to execute at runtime. ActionScript currently only runs in a Virtual Machine embedded in the FlashPlayer or AIR. Both runtimes provide additional APIs that allow you to draw stuff and get network i/o, etc. The current APIs use ActionScript 3 syntax and are focused primarily on Sprites, Shapes and MovieClips on a display list. New features were added in every major release. Now, Adobe is working on embedding a new Virtual Machine that runs the next-generation ActionScript in the FlashPlayer and AIR. The focus is on gaming, and a new set of APIs that talk to a 3d rendering engine is being devloped in the next-generation ActionScript syntax. There will be no support for the old Sprites/Shapes/MovieClips and display list. However, the old virtual machine that runs ActionScript 3 will continue to be embedded in the FlashPlayer and AIR that run on tradtional desktops/laptops. I would not expect it to be co-existent on mobile versions of AIR because the new focus is on the captive runtime workflow where you pre-process your ActionScript code and the runtime libraries into a device-dependent executable. So, given all of that, you can continue to deliver ActionScript 3 content in AIR or FlashPlayer on desktops/laptops “forever”. And unless you have heard otherwise from the PDF team, they probably won’t eliminate support for Flash in PDF on desktop/laptops soon. I think Apache Flex exists because folks have found the Flex workflow easy and productive and also safe because it uses structured programming, and former Flex customers are now pitching in to continue to evolve Flex as much as we can given the constraints of the current environment. The problem for many is that, because Adobe is not evolving the ActionScript 3 language, VM and runtime APIs related to it, folks see it as a dead end and no longer want to develop apps on it. I can see their point, but there is a reason why DOS is still around on some custom handheld devices: it works, it is well known, and has a small footprint for a constrained environment. Flash/AIR and Flex on ActionScript3 continue to be excellent ways to create apps quickly, but it has been difficult to convince customers to stick with it. Anyway, so far, the most interest in Apache Flex seems to be around trying to leverage the Flex workflow to create apps that run on the HTML/CSS/JS stack (without Flash). It will have growing pains for sure, but to me, a question about CPU load is premature. There is 1000’s of people from all over the world working on improving the runtime environment for HTML/CSS/JS. They have made significant advances in the past several years and I don’t see a cap on it. So any pain points you experience now are likely to be solved in the near future. If you can continue to use Flash/AIR and let others suffer through the growing pains, consider yourself lucky. Otherwise, put on some pads and join the battle.

Re: [flexcoders] Re: Flex alternatives
Well, there are several pieces. ActionScript is a language. It is really only the dozen classes or so in the “top-level” in the ASDoc. String, int, RegEx, Array, Vector, a few functions like unescape, etc, plus a bunch of keywords and stuff like “var”, “class”, plus a grammar of how you put it all together. It hasn’t changed much in years, other than the addition of Vector. There are no plans to improve on its specification by adding things it is missing compared to other languages like Java such as method overloading, or mutiple inheritance. Instead, Adobe is tossing out the whole specification and developing a next-generation of ActionScript. It will have some of the same things you see in the current ActionScript, but there will be new keywords and grammar. The goal is to give up on backward compatibility in order to get significant speed improvements by making the language easier to execute at runtime. ActionScript currently only runs in a Virtual Machine embedded in the FlashPlayer or AIR. Both runtimes provide additional APIs that allow you to draw stuff and get network i/o, etc. The current APIs use ActionScript 3 syntax and are focused primarily on Sprites, Shapes and MovieClips on a display list. New features were added in every major release. Now, Adobe is working on embedding a new Virtual Machine that runs the next-generation ActionScript in the FlashPlayer and AIR. The focus is on gaming, and a new set of APIs that talk to a 3d rendering engine is being devloped in the next-generation ActionScript syntax. There will be no support for the old Sprites/Shapes/MovieClips and display list. However, the old virtual machine that runs ActionScript 3 will continue to be embedded in the FlashPlayer and AIR that run on tradtional desktops/laptops. I would not expect it to be co-existent on mobile versions of AIR because the new focus is on the captive runtime workflow where you pre-process your ActionScript code and the runtime libraries into a device-dependent executable. So, given all of that, you can continue to deliver ActionScript 3 content in AIR or FlashPlayer on desktops/laptops “forever”. And unless you have heard otherwise from the PDF team, they probably won’t eliminate support for Flash in PDF on desktop/laptops soon. I think Apache Flex exists because folks have found the Flex workflow easy and productive and also safe because it uses structured programming, and former Flex customers are now pitching in to continue to evolve Flex as much as we can given the constraints of the current environment. The problem for many is that, because Adobe is not evolving the ActionScript 3 language, VM and runtime APIs related to it, folks see it as a dead end and no longer want to develop apps on it. I can see their point, but there is a reason why DOS is still around on some custom handheld devices: it works, it is well known, and has a small footprint for a constrained environment. Flash/AIR and Flex on ActionScript3 continue to be excellent ways to create apps quickly, but it has been difficult to convince customers to stick with it. Anyway, so far, the most interest in Apache Flex seems to be around trying to leverage the Flex workflow to create apps that run on the HTML/CSS/JS stack (without Flash). It will have growing pains for sure, but to me, a question about CPU load is premature. There is 1000’s of people from all over the world working on improving the runtime environment for HTML/CSS/JS. They have made significant advances in the past several years and I don’t see a cap on it. So any pain points you experience now are likely to be solved in the near future. If you can continue to use Flash/AIR and let others suffer through the growing pains, consider yourself lucky. Otherwise, put on some pads and join the battle.

Re: [flexcoders] Re: Flex alternatives
Adobe has no plans that I know of to get ActionScript to work with HTML5 in the same way that Google is proposing Dart as an alternative to JavaScript. The Apache Flex project is working on a compiler that will translate ActionScript to JavaScript. In addition, the link I posted proposes a component framework that would enable you to build or prototype your app in Flash using FlashBuilder and ActionScript and then run a separate tool outside of FlashBuilder to translate it to JavaScript where it will run and leverage HTML or HTML5 components. Alternatively, the same ActionScript to JavaScript compiler would let you write the script portions of your website as ActionScript using FlashBuilder and have separate HTML files, then use the same separate tool outside of FlashBuilder to translate the ActionScript to JavaScript. And maybe variations will be created that can output to various JS frameworks. At this time, there are no plans to change FlashBuilder to integrate the translation workflow. Adobe’s focus for FlashBuilder is on building ActionScript gaming and premium video projects that run on the Flash player. I suppose if the JS workflow became wildly popular and Adobe could see a revenue stream by supporting such a workflow things might change, but I wouldn’t count on it. There is a better chance that someone in Apache Flex will start creating plugins for Eclipse to support the workflow or one of the other tool vendors will provide an integrated workflow. The future of ActionScript 3 in Rich Internet Applications (as opposed to ActionScript “Next” as mentioned in the Flash roadmap) is actually being given more attention by Apache Flex than Adobe.

Re: [flexcoders] Re: Flex alternatives
I’m not sure I understood. These roadmaps are nearly a year old. Folks still thought that Flash Builder was being developed for Rich Internet Apps? I guess we failed again to get the message out. DesignView, as was discussed several times on the Apache Flex mailing list, is tied to specific SDK versions and as such, it was not possible for Adobe to certify DV against Apache Flex versions.

I think many people assumed that the driver was legacy in-browser flex apps, plus AIR apps for mobile devices.

The (baffling) removal of design view in 4.7 puts that impression to the sword, however. I'm not saying it's the wrong way to go - it's after all up to Adobe to choose where to invest their product development.

Re: [flexcoders] Re: Flex alternatives
Things get lost in translation, but one goal of the parallel frameworks is to not leverage things that get lost in translation. Otherwise, since JS and AS are ECMA-based, the translation works pretty well. Keep in mind that, while Adobe is no longer investing in ActionScript 3 on the Flash Player, and not developing Flash Player for mobile devices, and AIR may not run on all mobile devices, where the FlashPlayer is today, it will likely be there “forever”. So, if alll of your users are using desktops/laptops that have browsers that have Flash, you can continue to use Flex and/or ActionScript 3 to build applications and they will likely run there not just in five years, but even after that. There is no time-bomb in the players that will go off and stop running. Even though ActionScript Next and FlashPlayer Next are not compatibile with ActionScript 3, the AS3 VM will ship in the FlashPlayers that Adobe ships in the future. There is the possibility that the browser vendors will stop supporting plugins, but I would imagine they will keep a compatibility-mode somehow. I think there is too much Flash content out there and to block it from existing desktops/laptops would “break the web” and I don’t expect the browser vendors or Adobe take such a risk. There would be too much negative press. That doesn’t mean that new computers with new OS’s may not support Flash (that’s what Apple did with IOS), and many home users may forgo traditional computers for tablets in the future, so keep that in mind as well. I don’t know the PDF market that well, but again, I would expect PDFs to continue to support Flash “forever” as well. At least for the readers on traditional desktops/laptops.

Re: [flexcoders] Checkbox in grid
Renderers are recycled. There are only enough of them as there are visible
rows. Renderers get re-assigned to different dataprovider items as you
scroll. Therefore, every visible aspect of the renderer should be tied to the
dataprovider item. And that’s why reading back the value from the renderer
won’t work. There isn’t a renderer for off-screen rows.
On 12/7/12 12:14 PM, Davidson, Jerry jerry.david...@illinois.gov wrote:
I guess I’m just not getting it. The datagrid (id=dg2) has a dataProvider.
Each column in the grid is associated with one element in the dataProvider
except for the renderer where the checkbox is. That is in a renderer because
based on other fields it will be either enabled or not.
After a button is pressed, a routine is invoked that will loop through the
dataProvider source to see if the checkbox were clicked. What I don’t see is
how to connect the renderer to the dataProvider checkbox field. Any reference
to it causes a “can’t do that to a null object” message.
I added another field to the VO and in the renderer I can change the value of
a Boolean such that it is true if the box were checked. This was done by
adding a “change” event to the renderer. Since I could change the value of the
field I don’t see why I couldn’t change the value of the checkbox field.

Re: [flexcoders] updateDisplayList() called before commitProperties()
If you are adding the component in the updateDisplayList of a parent, I think that can happen.

Re: [flexcoders] windows 8 store app onscreen keyboard invoking
Are you sure focus went to the sprite? Make sure stage.focus is set and you
got FOCUS_IN and not FOCUS_OUT (and can get keyboard events).
It might be that there is a difference in the UIA in the player. Did you link
in the Flex accessibility code for the Spark components?
On 9/19/12 1:37 AM, Wouter Schreuders wschreud...@gmail.com wrote:
Hi Alex
I'm using Flex SDK 4.5A (problem also occurs on 4.6)
The flash player is version 11.3.372.94 on windows 8 64 bit and as far as I
know IE have gone the same route as flash and rolled their own version of the
flash player inside the browser.
Metro officially supports flash sites that comply with their conditions as set
out here (
http://msdn.microsoft.com/en-us/library/ie/jj193557%28v=vs.85%29.aspx )
Microsoft's official policy on invoking the keyboard is that it must be under
the control of the user and can not be problematically invoked. The way to
invoke the keyboard is one of the following from this page (
http://msdn.microsoft.com/en-us/library/windows/apps/hh465404.aspx ) :
Accessibility properties from UI Automation (UIA)
User tap
Focus changes
from their docs : UI Automation is the mechanism through which developers
communicate whether or not a particular UI element can receive text input. You
must ensure that the appropriate accessibility properties are set in your apps
so that the touch keyboard will know to appear when focus lands on a specific
UI element.
Their own windows provided controls do this automatically otherwise inside of
your html you need to add the following:
div contentEditable=true role=textbox
So that's how it works in html. I haven't found any documentation of help on
forums explaining how they decide when to bring up the keyboard in a flash
situation.
As you suggested I made an AS only site to see what works and what doesn't. a
normal sprite doesn't invoke the keyboard, neither does a sprite with a mouse
click listener. A normal textField doesn't invoke the keyboard but a textfield
with type set to TextFieldType.INPUT does invoke the keyboard (which makes
sense)
So somehow microsoft (I'm guessing) are inside of flash detecting what kind of
component recieved focus and if it's a editable textfield then it does bring up
the keyboard.
The intriguing thing is that for some reason when a spark textInput /
RichEditableText is set to displayAsPassword = true it DOES bring up the
keyboard so perhaps somewhere in the framework setting that flag causes the
component to somehow be perceived as a input component which quite strange to
me since I can't see why setting that condition would make any difference.
Here's my test code:

{
stage.scaleMode = StageScaleMode.NO_SCALE; //this stuff is required since I'm
working in flash builder and if you you don't put it in your graphics scale is
whack
stage.align = StageAlign.TOP_LEFT;
stage.quality = StageQuality.HIGH;

}

{
drawSprite(); // Does not invoke Metro soft Keyboard

Re: [flexcoders] Re: Tree Custom ItemRenderer - I need help
Looks like you want a 15 pixel gap (you are adding 15 in updateDisplayList) but
that is not accounted for in the measure() method.

Flex 3.x
I have been trying to construct a Tree Custom ItemRenderer that has basically
2 lines on the terminal branches. the first line should show the file icon
and the label, and the second line right below the first line should show
another label. It seems simple, yet when I try to do this the top label winds
up being pushed above the file icon, so there is something I am missing here.
Does anyone know how to do this or better yet can provide me an example that
explains how to do it?
Thanks,

Re: [flexcoders] Re: Tree Custom ItemRenderer - I need help
I think there is probably code in the default TreeItemRenderer that centers the
folder or branch icon. I think you can add code in your updateDisplayList
override to reposition the icon

the issue I am not understanding here is, when I add the second line label,
this causes all labels including the root label, to be pushed up so that they
do not align with their icon. there is something I am not understanding as to
how this works. I add the checkbox to the leaf branch at y=0 and that works ok
- it (checkbox) aligns with the label and icon for the leaf. Then I add the
second line at checkbox.y + checkbox.height + 15px line spacing. Now all the
labels are pushed up above their icons, about the height of the new label I
added. what am I missing here that is causing the labels to no longer be
aligned with their icons?
