Re: [flexcoders] IP adress for Language
Locale is the only thing that really works. IP/Country is fine if you have to model different business processes depending on the location (VAT tax vs Sales Tax). Export restrictions, etc etc. Remember, just because you know they might be in France, doesn't mean they don't prefer English. Over half the computers in Quebec are set to French in a predominately English speaking country. Locale is a user determined setting and using it allows you to accomodate their preferences.

Re: [flexcoders] Caringorm vs PureMVC
I prefer PureMVC as if you have any multi-platform development (say Flex and PHP, Flex and Java), there are PureMVC implementations for each platform. You can leverage PureMVC knowledge across platform teams, (hopefully) get better code, implement more cohesive standards, manage risk etc, etc etc. If developers cross teams, they are better prepared.KOn Jan 7, 2010, at 4:00 PM, Patricia Han wrote: Hi Everyone,I need to pick up a framework to use, either Caringorm or PureMVC.

Try-Catch blocks are an absolute necessity as without them, you are putting the operation of your software into the hands of user input errors, http errors, unintended consequences as well as the myriad of things that exist outside the Happy Path. As functions/methods only give you one return object, it is common practice to throw custom errors/exceptions as they are a great mechanism for handling dynamic environments.

RE: {Disarmed} RE: [flexcoders] Credit card processing in Flex
If the browser hosting your Flex component is connected in a HTTPS
session, then yes. I'm not aware of being able to start HTTPS
communication from a HTTP session. I believe that the SSL key (session
in place) needs to be in-place before you do your submit so posting
blindly to a HTTPS URL is not necessarily secure.
Of course, the ugly solution, a popup HTML window doing HTTPS directly.
You can also encrypt yourself in Actionscript with as3crypto (Google
code) although this might violate PCI/SET standards.
In Air, you can start an HTTPS session of its own.

RE: [flexcoders] flexlib and subversion
The metadata for SVN will conflict trying to cover two repositories in the same source directories. There are a couple of ways to overcome this. The first (and probably least risky) would be to use build automation with Ant and have your Ant scripts copy over your source to a shadow directory and have that directory be the local home for one of your repositories. The risks are getting that automation to see new package paths. I suppose rsync could help as well but I like the one tool approach for build. The second and pretty nasty is to swap out the metadata.. This is a bad idea.

RE: [flexcoders] Multiple developer environment setup with subversion and all offsite
Where to start.. First and foremost, the changes you are contemplating are an absolute necessity for a growing organization as well as, in the end, deliver manageable projects in the long term. Common development environment configurations: 1. Speeds the ability of new developers to come up to speed as you have the opportunity to document your configuration. 2. Eases the ability to return to an archived project and be productive. 3. Facilitates uniform build scripts (for scripted builds which are really nice). The larger your projects, the more you will want more and more automation. 4. Facilitates collaboration. Subversion: Your developers don't have to have every line of code in every project. In our Subversion repository we have probably 75 different projects (Flex, Java, .NET) across our development teams and product groups. Each developer checks out whatever project they are working on at the time. For example, a typical Flex project for our group is built from 3-4 subversion projects. This sounds like a lot of work, but when you get to building shared libraries, you will easily see where this approach has benefits. Your biggest issue to deal with in advance is to develop the rules/discipline necessary to make the team work together. There is nothing worse than a developer that infrequently checks-in as the risk of collision and re-work is magnified as the time between check-ins increases. You have to approach SCM as a collaboration mechanism and set policies accordingly. This means that you must develop standards that deal with the process of software development unlike anything you have done before. Common Rules: * Designate a person to perform Build Master/SCM Owner tasks (tags, branches, merges) * Frequent Check-ins * Prior to a check-in, a developer MUST update to the current revision and perform flexuint/acid tests verifying that the inbound changes don't break the build. * A developer who has checked in code breaking the build must fix the build immediately (before going home) Depending on Internet Connections: Although it's hard to accomplish and keep up, I like having local web servers and app servers. If that is too problematic, most developers use a single service over and over meaning for a majority of the time, they could consume a local XML document. Figure the services aren't going to be done at the same point the Flex side is ready to consume them anyway.

It is currently only me who is developing all the web and flex applications, but my boss has told me we are getting way too busy now for just one developer. I have a local development environment that I develop and test locally, then when I am finished with my tasks given and want my boss to finally look and test my work, I upload it to the test server. When the test is completed, we then promote to the production server. My problem lies at, 1). if we go to multiple developers, then they would also have to set up their local environment like mine and keep our code in their environment. 2). If we created the remote developer server then you are really depending on your internet connection. if that goes then you cannot develop. But on the flip side, all of our code would rest on our development server and not in their environment.

RE: [flexcoders] Encrypted html
Certainly going to be an issue with standard HTML renderers unless you can override them and insert your own behavior to an anchor. I expect that webkit, when presented with a file://filepath file:///\\filepath , will go load that file regardless of any click-handlers running in Air. An approach would have every click, call a Javascript handler and pass in the target of that click which loads your decrypter and returning the resulting page as the calling page source. Of course, that assumes that you have control of the page content, although I assume you could load and parse the DOM regardless. I expect a JS approach might imply security issues over a dedicated web server. I've used AppWeb before to build custom http based services but that always ends up being an effort of significant complexity.

RE: [flexcoders] Re: Flex Builder 3 crashes (Vista)
On Vista, I would search for other copies of that file in weird places. A synchronization folder for example. I have no experience running FlexBuilder(FB) on Vista as I prefer to avoid painful challenges where I can. Here is an idea for you (although a little off topic). We don't install the full FB IDE but rather do the follow.. It also makes FB a lot faster and reduces the memory overhead.. This may seem really strange. All of our developers install the C++ version of Eclipse 3.3.2 and then disable the C++ plug-in. Then install the FB plug-in. There is just so much goo that comes in with standard FB from Java and JDT that when you will be surprised how quickly it boots. Downside is that those who do both Java and FB end up with two installs but we try to isolate Flex developers from IDE pain so I don't let them install many plug-ins anyway. The way the MXML preview component leaks memory, you have to take whatever shortcuts you can.

RE: [flexcoders] Re: LocalConnection issue in AIR to AIR application
And one other important note. The ADL runtime (the debug player) needs special handling in order for enable communication to happen. You need to set command-line arguments to make it work with Air to Air communication work. Note: When you run your application with ADL (or with a development tool such as Flash CS3, Flex Builder, or Dreamweaver), the publisher ID is null and must be omitted from the domain string. When you install and run your application, the publisher ID must be included in the domain string. You can assign a temporary publisher ID using the ADL command line arguments. Use a temporary publisher ID to test that the connection string and domain name are properly formatted. adl [-runtime runtime-directory] [-pubid publisher-id] [-nodebug] application.xml [root-directory] [-- arguments] -pubid publisher-id Assigns the specified value as the publisher ID of the AIR application for this run. Specifying a temporary publisher ID allows you to test features of an AIR application, such as communicating over a local connection, that use the publisher ID to help uniquely identify an application. The final publisher ID is determined by the digital certificate used to sign the AIR installation file. Better yet, export your Air runtimes and try without the adl fun.

RE: [flexcoders] Re: AIR and SQLLite
If you don't have to preserve any existing client data, then you could simply rip and replace the existing db file. Your Air application could drop the file, back it up or whatever and then replace it with another copy downloaded from a server. If you need to preserve some of the data then your problem becomes much more daunting. First you need to determine the rules by which an update is to occur. Is it at application start or part of some predefined schedule? What happens if one user leaves their client up for days/weeks/months and another restarts hourly? If you base on application start, how will you insure that you cover both use cases? How will you insure that client A and client B don't have different data? I would suggest adding timestamps to every server synchronized row allowing you to implement some concept of knowing what data might be stale.

RE: [flexcoders] Creating Asynchronous Classes
We use MD5 and understand the issue completely. We use classes that look at the file a chunk at a time as we don't want to load 60+MB MP4 files into a ByteArray. Our solution did help in keeping the general memory overhead under control. The issue becomes one of time as although our Air client can usually bring a large file down in a reasonable amount of time (let's say 1-3 or so minutes for a broadband connection) the sticky point is the MD5 typically ate another 2+ minutes to complete. Likewise hoping to implement a progress indicator, MD5 (or any CRC like mechanism) is processor heavy leaving you with the challenge the balance of running an animation at the same time you want your processor to be handling your check with the more animation, the slower your CRC will be.

RE: [flexcoders] Any Developers on a Mac?
Speaking for my organization, we have a team with both platforms as well as a number who run Mac's in a virtualized environment with Flex on both the Mac and PC sides. Speaking for us, I can say the biggest single issue we have is the fact that project files get checked in. Although the project files work equally on both platforms, what really gums up the works is going thru Flex upgrade, for example SDK 3.0 to SDK 3.1, can be a big headache. Don't get me wrong, checking in project files can provide a significant productivity gain as getting developers up to speed in a common development environment is a big help. When the SDK string, in the .actionScriptProperties gets parsed to point to either an SDK that isn't there anymore or its identity has changed, you will get to the point where the project properties can no longer be viewed or modified. We has seen this cause workspace and compiler errors as well. The only reasonable workaround to this condition is to create new empty projects, move those new project files aside, checkout your project and then restore those newly created project files and then go through the process of manually setting up your projects. So you ask yourself, why not just check-in updated project files? Certainly a solution however there are a number of reasons why I choose to avoid that. The project files carry with them asset and class bindings that may or may not be appropriate for each developer to automatically inherit.

Subject: [flexcoders] Pattern for capturing multi-key/click actions?
I would like to add multi-key/click functionality to my Flex app.
There are a couple of slightly different examples of what I mean:
1. Detect when a user is holding down the 'r' key while clicking a
button.
2. Detect when a certain component has focus and the user types the
letters 'd' 's' in succession within a few seconds of each other.
I noticed there are properties in the MouseEvent class to detect
things like shift,ctrl and alt keys but I need to detect more than
just those. Additionally those properties don't exist in other event
classes like ItemClickEvent.
What I have done so far is simply create a state object at the
application level that captures all keyboard/mouse events and sets the
state of itself based on the events. Individual components can check
the current state at any time to determine which keys/mouse actions
are currently active.
I don't particularly like this implementation for many reasons and was
hoping someone knew of a pattern to use considering many applications
support such functionality (Eclipse comes to mind).
Thanks!

RE: [flexcoders] Upload file(from local machine) via web service
Depends on what you mean by support and what you are actually trying to do. Can I assume you are talking about an AIR application (as you are referring to the FileReference class). Is there a canned function that takes a file reference and uploads it to a server? No Is there a HTTP client allowing you to create almost anything? Certainly. First, a file reference is simply a reference to the file. You will need call the upload method on that reference and pass it a valid URLRequest object. For our organization, we choose not call web services with binary data uploads but rather use multi-part forms to perform the upload of images and other complex objects. If your plan is to load the file and post the contents of that file more along the lines of REST, then you can easily get to the data of the FileReference and post that as well however pay attention to the necessities of encoding the payload.

RE: [flexcoders] FZip loads cached zip before downloading online
Not sure exactly what is happening but I suggest an improvement to your
approach.
You should detect the change in network connection status and use that
event to flush any objects that are waiting on an event to fire. AIR
fires a NETWORK_CHANGED event and I would make sure you clean up your
objects at that point. You cannot depend on the quality of the bits you
just downloaded regardless and need to re-enter the process.

Subject: [flexcoders] FZip loads cached zip before downloading online
I'm using FZip in an AIR application, the application loads the zip
from a location on our server, unpacks the zip and move the files to
their local folder. Everything runs smooth until I cut off my internet
connection while the zip is downloading.
When I restart the application it looks like FZip is first checking
the temp folder for the cached zip and if found, it uses that one to
unzip, even if the zip was not completed the last time.
Does anyone know of a way to prevent that?
I use the default load method of the FZip library, this is a part of
the code I use.
var moduleLink:String = [EMAIL PROTECTED];
var zip:FZip = new FZip();
zip.addEventListener(Event.COMPLETE, onComplete);
zip.load(new URLRequest(moduleLink));
private function onComplete(evt:Event):void
{
var moduleDir:File =
File.applicationStorageDirectory.resolvePath(modules);
var outStream:FileStream;
for(var i:int; ievt.target.getFileCount();i++)
{
var zipFile:FZipFile = evt.target.getFileAt(i);
if(zipFile.sizeUncompressed == 0
zipFile.filename.toString().substr(-1) == /)
{
var rootDir:File =
File.applicationStorageDirectory.resolvePath(modules/+zipFile.filename
.toString());
}
else
{
var tempFile:File = moduleDir.resolvePath(zipFile.filename);
outStream = new FileStream();
outStream.open(tempFile, FileMode.WRITE);

RE: [flexcoders] Re: FZip loads cached zip before downloading online
When you destroy the FZip object, don't necessarily know and if you
don't know, you have to clean up after yourself. Remember, when you use
HTTP, you are subject to timeouts that may or may not expire as you
expect them let alone the myriad of other errors along the way
(permissions, server error, etc). If you only wait for a Complete event,
then the HTTP object is left hanging and the file is certainly in a
dirty state as well.

RE: [flexcoders] Odd message on export of release build of AIR app
I believe what you are seeing is an issue with FlexBuilder where the list of classes in the Library Build Path includes a reference to the missing class. We see this mostly when we use either SubClipse or Subversive dealing with the Asset List. They basically trigger a build before all the project assets are in place corrupting (in the Java sense) the manifest or those who check in the project files (.project .flexproperties .actionscriptproperties) causing platform specific issues. Basically these lists get incrementally updated during the development lifecycle and never get completely refreshed until someone goes to the Library Build Path (Project-Properties-Library Build Path) and touches the list. This UI is used to determine what classes to make active in the project so if you are using it this way, then you will need to track what should be linked in and what shouldn't. Most though, that I am aware of, don't use the Build Path this way so the brute force fix is to uncheck all the classes, close the form, re-open the form, choose all classes and save. If you manually bind and unbind classes, then you will need to uncheck one class, close the form, open the form, recheck that class and then re-validate your list of excluded classes.

RE: [flexcoders] REST Library for Flex or ActionScript?
There are a couple but none are comprehensive. The ones of note are - Flickr actionscript API's on google which are nice if you need to see both the API and a number of comprehensive ways they are used. I would rate them ok: - Arc90restlib - is more of a pattern then a nitty-gritty REST library. Ultimately we didn't use either as we are proponents of a strong factory pattern as well as the fact that we use REST in order to interact nicely with our load balancers/caching servers and we needed a strong multi-part form binary upload capability. We ended up writing our own REST implementation. You have to also remember in the AMF/FDS world you get some native error handling since the technologies on either end can be aware of each others that you have to build yourself in REST. The biggest word of caution using any external API set is to evaluate error handling as a majority of library distributions focus on the Happy Path and either ignore or gloss over when things go poorly. It really doesn't give your application a chance to gracefully recover if the only error you get back is Oh Crap. HTTP by nature empowers the application to respond differently to the range of HTTP errors it generates so with a REST library, it's your responsibility to account for a permissions issue differently than a server error.

[flexcoders] Anybody found a workaround for this compiler bug?
This is sapping our productivity and wondered if anybody had seen this or had any ideas? I certainly see the association with Font rendering as the obvious first instinct would be to question the font file however with two machines seeing the same behavior, a wider look seems appropriate. There is Away3D in the project and we do take the TVNord font and render the SVG in order to support text overlaying on a 3D plane. Since the Clean always resolves the issue, I doubt that the base font file is the issue. We currently see this on 2 developer workstations, one a Mac, one a PC. The only way to get around this is to clean all the projects in the Workspace (this is part of an application where we have an Air project and 3 support library projects. Doing a Clean of the Workspace allows us to get past this (until you need to build again).

Adobe did add support for dates in SQLite, see excerpt below. The problem is most third party applications that support SQLite don't understand it so you will have limited ability to work with them, for example in the Firefox SQLite Extension For precision and for wider access to the database beyond Flex, we typically convert the date to its serial value and store that. It is highly portable and allows you to interact with it nicely. (although you have to do the conversin back obviously). Additional SQL features The following column affinity types are not supported by default in SQLite, but are supported in Adobe AIR: STRING: corresponding to the String class (equivalent to the TEXT column affinity). NUMBER: corresponding to the Number class (equivalent to the REAL column affinity). BOOLEAN: corresponding to the Boolean class. DATE: corresponding to the Date class. XML: corresponding to the ActionScript (E4X) XML class. XMLLIST: corresponding to the ActionScript (E4X) XMLList class. OBJECT: corresponding to the Object class or any subclass that can be serialized and deserialized using AMF3 (which includes most classes including custom classes, but excludes some classes including display objects and objects that include display objects as properties).
