Re: [flexcoders] Re: WebORB or AMFPHP for big Application
Keep in mind that AMFPHP may go under the radar (or drop off it completely) as the lead developer has decided to pursue another career and I have not seen any announcement of anybody else taking over for him. I'll be releasing amfphp 2 before I retire, and I have someone here that is interested in picking up amfphp, someone I can't mention just yet but trust me that my successor will be a very talented and respected member of the community that I am sure will do an awesome job with the project. As to which you should choose between amfphp and WebORB, it depends. Mark loves his WebORB, and I love amfphp, but they are different projects, and have different design goals, so that either one is most appropriate for different uses. The differences are subtle though, I'll be the first to admit, which is why I wasn't particularly thrilled about WebORB and SabreAmf when they first came out, as I felt it was a duplication of efforts (much like the well-publicized argument over SWX with Aral). But regardless, the effort has already been put in, so there's no use in stopping it now. I'll restate the design goals of amfphp from the homepage: - Nothing required - PHP4/PHP5 compatible, no extensions needed - Low footprint, lightweight, fast - Convention over configuration (service and class mapping) - Can be embedded into a framework (see CakeAmfphphttp://cakeforge.org/projects/cakeamfphp/, Seagull http://trac.seagullproject.org/ticket/1378) - Services are non-specific PHP classes that are portable to anything without code change - Productivity tools included (service browser, code gen, profiling) - Batteries included - XML-RPC, JSON - Not a framework by itself (use your own) I'd like if Mark could put up a similar statement of design goals for weborb so that users can make an informed decision. As for the issue of the AMF extension, I've contacted Mark about it, and in theory weborb could be made compatible, and SabreAMF will be eventually (as far as I can tell). I don't think Mark wants to do it though, perhaps because of the way the serializer is implemented on their side. My personal feeling is that the serializer and unserializer in WebORB are misadapted to the realities of PHP, split into several classes for doing simple, computationally intensive things, but one could argue (and I'm sure that Mark would) that clarity of code was chosen over performance, a valid decision if it doesn't affect performance that much (and Mark is right, the 50-200ms difference won't really make a difference in most projects, but in some which have very high traffic it most definitely will, which is why the AMF extension was made).

Re: [flexcoders] cacheAsBitmap - does anyone know?
You should only use cacheAsBitmap if you plan on modifying x, y, and alpha properties of a sprite. Changing rotation or scale means that the cache will be reset, so you will have worse performance. Adding a filter to anything sets cacheAsBitmap to true on it, but not on any of its children. Nevertheless, you should know that if a parent container uses a filter, moving or doing in the children of the container will cause the filter to be flushed and recalculated. Patrick Guy Morton a écrit : I've created an mxml component that uses a canvas object and writes a graphic on it based on some input parameters. This graphic is then animated over a bitmap background. If I set cacheAsBitmap on the graphic's canvas to true, then rotate the canvas, am I improving performance? Or does the rotate mean flash will throw away the previously cached bitmap and make a new one? Also, does having a drop shadow filter on the parent canvas container affect the behaviour of cacheAsBitmap? Guy

Re: [flexcoders] Re: amfphp + codeigniter
You have a few options here. The first is to call flickr directly
through XML-RPC using Flex. You could use plain old E4X for that, or you
could use a wrapper library for it. Try it here:
http://www.hrum.org/people/debedb/pro/blog/2006/12/xmlrpc_in_flex_2actionscript_3_1.html
As Renaun mentioned, you could also use REST services for Flickr, they
work just as well. If I have a choice between REST and RPC, generally
I'll choose RPC, but I don't know how good the library I just linked
actually is.
The third option is to use a middle man, such as amfphp. In that case
you could use the XML-RPC functions built into PHP, and just have amfphp
resolve them. For example:
?php
class FlickrService
{
function doCall($function, $args)
{
//For example, $function = flickr.photos.getRecent
$apiKey = YourAPIKey;
array_unshift($args, $apiKey);
|
$request = xmlrpc_encode_request($function, $args);
$context = stream_context_create(array('http' = array(
'method' = POST,
'header' = Content-Type: text/xml,
'content' = $request
)));
$file = file_get_contents(|http://api.flickr.com/services/xmlrpc/|,
false, $context);
$response = xmlrpc_decode($file);
return $response;
|}
}
?
Then just use ro.doCall(flickr.photos.getRecent, []);, where ro is
your RemoteObject instance. That might be slower than a direct call but
then again, you don't have to store the API ky on the client (a bad idea).

Re: [flexcoders] Are other developers hesitant to extend existing classes in Flex?
I've had a lot of issues as well with private functions. I would have suggested to use protected basically everywhere since you can't really plan for where developers will want to modify the components. As far as composition vs. inheritance, well, composition doesn't solve every problem. I had an issue with the slider class firing data events when it received a data-binding value, even though the NumericStepper didn't do that. Because the problem function was private and buried very far in the component hierarchy, I basically gave up. It was a one-liner kind of issue too. Patrick Doug McCune a écrit : I've had a similar experience many times, so I'll chime in with what I've been doing. The problem: you want to make a simple extension, and you see the part of the original source that you need changed or enhanced. So you try to make a subclass but you end up finding out that to do what you need done you need access to a handful of private variables and functions in the parent class. My solution: I make a cut/paste copy of the original class, name it something like OriginalClassBase. as (so like AccordionBase. as) and then I extend that new base class. What this allows me to do is make some very slight modifications to the original base class, which usually only involve changing certain variables or methods to protected as opposed to private. This is bad for two reasons: 1) you're duplicating the original component in the code base, so you'll bloat the end size of your file and 2) future updates to the original class won't be included in your extended class. Problem 1 is often worth the price, since that's really the only way I can figure out to do some of the tings I want to do. And I've already resigned myself to multi-hundred kilobyte SWF files, so whatever. But if you're psycho about file size this might prevent you from taking this approach. Problem 2 I don't really see as that big a deal and here's why: the changes you're making to the base class are minor. This means that if an update comes out to the Accordion class, my copy/paste version can be compared within Eclipse using the compare functionality and I can identify exactly where the differences are. So if an update to the Accordion is released in Flex 3, then I can compare my base class with the updated Class, and either make a new base class using the Flex 3 version, or decide that I don't need to bugfixes and enhancements they rolled into Flex 3. This is just my approach. What I've found over and over again is that to really make the enhancements I want, the components simply haven't been designed quite right. This isn't to say that Adobe should have been able to anticipate every scenario that I would want to do with a subclass. Thank god they included the source for the SDK though.

Recently, I spent several days trying to override the placeSortArrow function on the datagrid. I ended up ditching my code because there were so many private variables used by the existing placeSortArrow( ) function that I would need to rewrite most of the datagrid.as http://datagrid.as file.

Re: [flexcoders] Displaying Mathematical Formulas in Flex
You could use a LaTeX renderer to do this, which would be located on the server. I've used MimeTex and it's worked great for me.

Without going into a great deal of detail, I need to be able to generate and display mathematical equations within flex (complicated ones). I had a few thoughts on the issue: 1. If I could have an outside script that could create the equations and save them as images, it would be fine. However, it would have to be web app - not a desktop one. If there were a library for PHP's GD Library or something like that. 2. If there were a Flash Component that could generate the equation, I could easily write a script to extract that data and save it in some useful format. 3. If I had to, I could leverage the browser and use the IFrame concept first demonstrated by Christophe Conraets. However, there is still no widely supported way of displaying equations in HTML (yes, I know about MathML - but it is still not fully supported in all browsers without plugins).

Re: [flexcoders] Re: AMFPHP Security
I think you're misunderstanding my argument Mark. Of course you can spoof any message you want, and you don't have to be an expert either to do it; you could use the amfphp service browser of SabreAMF as a library or a Flash movie to send any message whatsoever to a gateway. The issue with class mapping is that when developers put something in the service folder, they know that the code can be included and methods run on it. If they care about security, they will take care that the methods defined are not dangerous if remotely executed with other data. But from talking to a very well-known blogger (a Java fan) and seeing some of the new code that is going around in tutorials, I see that while people are taking care of escaping strings before sending them to a database and the like, they don't bother to check the argument type that's received, and while that may not be dangerous if you receive an array instead of a string, it may be if you receive a live object which has code in it which may be executed. The locking mechanisms which apply to amfphp, WebORB or Fluorine are per-method, but class mappings in most implementations is per gateway (at least, that's what it is in amfphp, Fluorine, or OpenAMF). So you could call an unlocked method with a mapped class that you would only expect to receive in a locked method, and if that mapped class has side-effects it could do some damage. Because class mapping and VOs are often used in database scenarios, we're talking about potential data-loss issues here. It's a far-fetched scenario, but the main issue is that it is such an unobvious scenario that you might not actually think about it, and you might not think about securing against it. About the Our implementation (weborb) does it quite well, I'm not sure what you're referring to by it. Could you expand? Patrick Mark Piller a écrit : Zoli is right. Usage of a specific object type in a method signature is irrelevant to security. In fact, you do not even need to know AMF to do it. One could easily use something like ServiceCapture to understand the structure of the argument type then construct a similar object and run it a local Flex/Flash movie with unrestricted security. Essentially it means that a gateway must safeguard against such malicious attacks. Our implementation (weborb) does it quite well.

Re: [flexcoders] AMFPHP Security
Amfphp is not inherently less secure than FDS. Anybody who wants to can
spoof requests to FDS or amfphp, just like they can for HTTP POST. As a
side-note, users don't have to bother to decompile your SWF; they can
just sniff packets coming in or out of your movie using ServiceCapture
or Charles.
The rules for securing Remoting apps aren't any different than the rules
for HTTP POST: don't trust data, secure sensitive methods
(deleteEntireDatabase(), for example), use sessions to identify users,
be wary of SQL injection, don't send SQL over the wire, use SSL when
sending credit card/banking info, etc. Just common sense really. The
only thing that you should be worried about that doesn't have an
equivalent in HTTP POST is sending VOs. Since they are mapped
automatically and VO types are uneforced, someone can spoof VOs and make
them any type they want. For example, consider the service function:
function deleteUser($userVO)
{
$userVO-delete();
}
Well, you might expect that $userVO is a com.myPackage.UserVO, but it
could also be a com.myPackage.PhotoVO, or a com.myPackage.AdminVO,
or whatever. So you either have to make sure you do receive the VO type
you expect, using instanceof or is_a, or you should only use dumb VOs
which don't have any methods. This and the fact that assignments on a
class for variables that not defined won't cause a warning unless using
E_STRICT, which amfphp won't run in (as it's impossible to work in
E_STRICT while supporting PHP4), means that using VOs in amfphp (and in
PHP in general) is IMHO bad practice. VOs make a lot more sense in fully
(runtime, not just compile-time) typed languages.

security, but not AMFPHP. Is AMFPHP inherently less secure OR more
secure than any other data service technology. The app I am building
requires as high a level of security as I can reasonably enable.
Thanks,

Re: [flexcoders] AMFPHP Security
I think you are being very reasonable here when considering VOs, as a
lot of people tend to use them blindly, esp. people coming from Java
backgrounds. A thing I hear very often is with VOs you can be sure what
data you receive, which is true in a typed language, but in a dynamic
language, that's just not right.
Consider for example:
void addComments(CommentVO[] commentVOs) (Java)
Versus:
function addComments($commentVOs) (PHP)
Of course in Java, if a user tried to send an array of UserVO to
addComments in the first parameter, it would throw an error. In PHP
however, because it is untyped, no error is thrown, so you have to
manually check if you get the right type. Now if UserVO and CommentVO
both define an add() method, you can see that your addComments methods
could also be used to add users. Of course if users have administrative
rights, someone might use this to inject a new user with admin rights in
the db, and could wreck havoc on your system. The difference between
this and spoofing a call is that this is a really subtle security hole,
so you might not think about it. Honestly, it's not a huge hole, you
could definitely do a lot worse (I've seen people send SQL over the
wire, unencrypted, and unsecured), but I don't think trying to make PHP
into Java is a great idea (if so, why not use Java in the first place?)
I really see no issue in sending VOs back to Flash, because Flash runs
in a sandbox, so the worst that can happen is that the hacker's app
stops functioning. But sending them to the server... not the greatest idea.
Now I've seen a lot of code that looks like this:
$rs = mysql_query(SELECT * FROM the_table);
while($row = mysql_fetch_assoc($rs))
{
$vo = new UserVO();
$vo-id = $row['id'];
$vo-name = $row['name'];
$results[] = $vo;
}
return $results;
How is this any better than:
return mysql_query(SELECT * FROM the_table);
...I'm not sure... seems like it's quite a bit more code to add that
doesn't really serve that much of a purpose. Sure, you'll get VOs on the
Flash side, but if they are dumb VOs... what's the point?
Now if you actually want to send more complex data to Flash, for
example, if you wanted to send back a PostVO that includes an array of
CategoryVO, then since you're going to have to traverse the MySQL data
set anyway, you'd be justified in adding typing in as well. So basically
I'd say if you need simple data, stick with plain arrays and objects, if
you need more complex things, then VOs are cool. Right tool for the
right job, basically.
About ORM, the next version of amfphp will support Zend DB, so I'd
recommend trying out Zend_Db_Table, I looked at the docs yesterday and
it's pretty sweet. Doesn't handle associations or anything but it's
still cool. There's also Propel/Creole.

So you either have to make sure you do receive the VO type

I think that this is an important point, so I want to make sure
I understand what you are saying since I have been debating whether to
use VO's in my PHP.
I can create dummy VO's as you suggested (which is essentially what my
Flex VO's are), but I have been wondering what advantage I get from
using VO's at all in PHP unless I attempt to implement an ORM approach
and actually map the PHP VO directly to the MYSQL tables and abstract
my SQL into these objects. I have been a little wary of this approach
(for reasons other than security) since I need a more flexibility in
my inserts, AND it sounds like you would not recommend this either due
to the security holes it could reveal.
However, the other advantage of VO's on the PHP side is to allow them
to manage the deserialization of my MySQL results, and thus fully
organize them into objects that can be easily mapped back to Flex. So...
a) Does this present as big a security issue?
b) Is a good way to approach the mapping of PHP to Flex? How are
others solving this problem.
c) If one could spoof a VO, wouldn't it be just as easy to spoof a
method call (assuming I take a more procedural approach).
I guess I don't fully understand why the procedural approach is more
secure than the VO approach.
I am new to understanding web security, so forgive me if I am being
naive...

Re: [flexcoders] AMFPHP, Cairngorm VO
Sure thing. If you want to return an array of com.one.of.my.customVO,
then say the php class is:
?php
class customVO
{
//Declare variables below
var $_explicitType = com.one.of.my.customVO;
}
?
PHP doesn't support packages, so to send the full package name to Flash
you have to set the $_explicitType variable. The value of $_explicitType
should be the same as that of [RemoteClass], ie:
package com.one.of.my
{
[RemoteClass(com.one.of.my.customVO)]
class customVO
{
//Stuff in here
}
}
Then the rest is done for you. So for example:
function getArrayOfCustomVo()
{
return array(new customVO(), new customVO());
}
That's pretty much all there is to it.

Re: [flexcoders] AMFPHP, Cairngorm VO
alias is the default property for [RemoteClass], so you don't need to
explicitly write it (just like, say, Embed source)
Patrick
Kevin a écrit :
thank you. Here is where I was making my mistake (in case others are
having the same problem):
when declaring the $_explicitType variable, I was mistakenly putting
the path to the variable in my Flex dir rather than the path in my PHP
dir.
var $_explicitType = com.one.of. my.flex.customVO ;
should have been:
var $_explicitType = com.one.of. my.customVO ;
I don't know why, but I guess I thought I should tell PHP where my
Flex VO was...like it cares!
Anyway, thank for setting me straight.
BTW, I have always seen the [RemoteClass( com.one. of.my.customVO
)] write with alias =.
[RemoteClass( alias= com.one. of.my.customVO )]
Is this a typo or is the alias optional?

Re: [flexcoders] hostmysite, mySQL5, CF7, WebService, and Flex2 problems...
You should try using ServiceCapture or Charles debugging proxy to inspect the data being sent over the wire when an error occurs. Patrick qnotemedia a écrit : I have two Flex apps using all of the above that perform flawlessly on my localhost, but after moving them to hostmysite.com, they have sporadic issues. Its always an error statement that I have created, in a Flex Alert.show fault return, though I'm not entirely sure if where the actual error is taking place - I would assume in CF. What I have is two CFCs, one with all of my DB-changing functions, and the other with my get-data-only functions. At the beginning of my app, I call out maybe seven webservice calls to the read-only CFC to grab data, and again, while it works perfect on my localhost, once on hostmysite, anywhere from 1-3 of these may or may not fail. Its very random. Many times, the app will work just fine. I wanted to use remote object, but unfortunately, hostmysite doesn't support this, so I'm stuck with WebService. Where do you think these random failures are happening, why is it happening, and what can I do about it?
Re: [flexcoders] Re: hostmysite, mySQL5, CF7, WebService, and Flex2 problems...
Yes, maybe it's a question of the order of the requests, or maybe you are running into race conditions of some kind. Try enabling throttling in ServiceCapture and set it to a low value (like 56k) to see if it makes the problem occur more frequently or less so. Maybe that will give you a hint as to what is going on. Patrick qnotemedia a écrit : Wow - ServiceCapture is really cool! I didn't know you could see stuff like that so easily. Unfortunately, its not showing me anything new. i.e. when an error occurs, the results in ServiceCapture look the same as a session where the app doesn't return any errors. What does that mean? There's eight webservice calls when an app is first loaded. One thing I did notice is that the order of these calls appears to differ depending on the session. I didn't think that any one service call requires another, but considering the sporadic nature of the errors, is it possible that the problem here is that simple?

Re: [flexcoders] Datagrid Scrolling -- Is it really this complicated?
Granted, the behaviour of the datagrid is not optimal, but then again, why would you want to show 68 columns simultaneously? Even if the scrolling did work as you expect it to, that doesn't sound very user-friendly. I'd suggest thinking of another interface instead. For instance, you could show 3 or 4 columns and when you click on one row it could show the details in another panel.

Re: [flexcoders] RPC Pro's and Cons
Basically you want to use RPC when you are going to consume and send data on initialization and based on user interaction (ie: pull). You want to use FDS when you need to notify a client to update its data based on a server event, or keep data synchronized between clients (ie: push). There are other reasons why you might want to use FDS, like recordset paging and whatnot, but as a rule of thumb, use RPC (esp. Remoting) for pull and FDS for push. Of course, you can simulate push in Remoting using polling, but you will find that it's a pain to keep everything in sync for more than basic functionality. And of course, you can do pull over FDS, but it has a major learning curve, requires knowledge of Java as opposed to your favorite language, and is a bitch to deploy, compared to, say, using amfphp or Fluorine.

Re: [flexcoders] Flex Accessing HTTP Session
No, HTTP sessions are stored on the server-side, so you can't access them from just the client side. The only thing you CAN access on the client side is cookies, which may contain the session id, but the actual data is stored on the server-side, indexed by that key. Patrick 2006/12/27, Ryan [EMAIL PROTECTED]: I was curious if there was any way that flex could access a HTTP Session. I have not seen any type of tutorial/doc posted that might work other than a very small note in the help section of flex's installed doc's. At this point my only solution is to use flash vars to capture the session ID, then I'm going to write a Web Service that will take that Session ID and return all the variables I need. I was hoping that there might be an ez'er way cutting out the Web Service. Thanks, Ryan

Hi all,
I discovered a problem with uploading files to a server in flex2 using
FileReference. upload
(). My code includes something like this:
[...]
private var fileRef:FileReferen ce = new FileReference( );
private function someHandler( event:Event) :void {
var request:URLRequest = new URLRequest( band/upload_ image);
fileRef.upload( request);
}
[...]
On the backend I use ruby on rails to handle the upload. The problem
is that every time
fileRef.upload( request); gets called a new session will be created in
rails (that means I have
to re-authenticate my user before every upload request). On the other
hand, if I replace
e.g. fileRef.upload( request); with navigateToURL( request, _blank);
(even if this makes no
sense here) the existing session will be used.
So why does fileRef.upload( ...) creates a new server session on every
request? Is this a
bug?
Best regards
René

Re: [flexcoders] Question for all you SQL Query experts
I would suggest looking at what google does. It allows and/or searches in a completely unobstrusive manner. I would use only one search field, with the following algo: 1. split on 'OR' 2. split on words 3. join on words with AND 4. join on words with OR I would definitely search on all fields in your table. In split on words you might want to take into account words in double-quotes. Also I would use LIKE everywhere. Patrick Mike Anderson a écrit : Hello All, I was wondering how you more seasoned SQL programmers (as it relates to the User Interface side of things), provide the ability of advanced SQL Queries to novice users - but in a easy to use and non-threatening manner? We have an extensive parts database, and the only way to truly search this thing, is by giving users the ability to perform robust and, or as well as and/or type queries. Back in the HTML days, I would simply give the users 4 sets of blanks, in which they could put in 4 unique sets of search criteria - with And or Or in a DropDown box. This worked well enough I guess... but for the power-users, who wanted to perform more advanced queries - with more than 4 search criteria, I was always in a quandary as to what to do. There is a fine line between functionality and usability, especially when it comes to Data-Driven applications that are very Text Intensive. With Flex having the ability to offer such spectacular user interfaces, I was wondering what techniques I could use NOW, that could offer a truly powerful user experience - but still *keeping it simple*. I would love to hear some input regarding this topic - Thanks in advance for all your help, Mike

To test the new features, I've created a new Service Browser in Flex 2 which allows you to introspect services and test methods on the fly. I need people to test out the new AMF3 support. New/changed features: - $this-methodTable is DEAD. All methods in /services are now considered remotely accessible, unless you set them to protected or private (PHP5) or start the method name with an (_), in which case it will throw an error. If you want to get a description of a method and it's arguments without looking at the class itself, add JavaDoc to the method and you should see it in the new Service Browser. - _authenticate is dead, as a side-effect of the removal of the methodTable. You can secure methods by creating a special function called beforeFilter($methodName) in your class and return false to stop a method from being executed. (the _ and the beforeFilter are the conventions used by CakePHP, so I figured I'd use those instead of rolling my own). - Circular references in AMF0 and AMF3 should now work. Class mapping code has been ported to the AMF3 code also. To use remote class mapping, use registerClassAlias or the [RemoteClass] metadata tag, then read the instructions in advancedsettings.php - Returning a mysql_query will now return either an Array or an ArrayCollection depending on the setting in gateway.php. Other database types are currently unsupported in AMF3 mode (they will be supported as soon as I am sure the AMF3 code is perfect). - You can send ByteArray, ArrayCollection and ObjectProxy instances as arguments to remote methods. You will receive the result as a string, as the inner array and as the inner object, respectively. Currently there is no way to send back these types to Flash, but there will be in the next version. - /browser now brings up the brand spanking new Flex 2-based service browser. You can test methods directly through it. If the method returns an array or arraycollection, the browser will attempt to show it in a datagrid (sweet). Please feel free to modify servicebrowser.mxml (it's very spaghetti-code-ish, but it works). You will need the Adobe corelib to compile (google for the link) Limitations/things to keep in mind: - MySql works but not other databases - You can use a JSON string for arguments in the service browser. However you must wrap object keys in quotes (a limitation of Adobe corelib). - Paged recordsets don't work anymore - Only tested in PHP5. PHP4 might show issues with circular references. - Calling two methods on a remoteObject one after the other (during the same frame) might not work. - Charles and ServiceCapture have some issues with AMF3 handling. You might see strings which seem out of place in your output while it works fine in Flash. I will notify the people involved. You might want to set PRODUCTION_SERVER to true in gateway.php if this is a recurrent problem, in the meantime. - If you need to send to Flash a class and want it to be mapped to a class in a package, you need to add a key to the class called _explicitType with a value of com.mypackage.TheClass and use registerClassAlias or [RemoteClass] as usual ( a limitation of php not supporting packages) All that being said, I need testers. Please download it here: http://5etdemi.com/uploads/amfphp-1.9.alpha.zip (although it states it is amfphp 1.9, there will be no amfphp 1.9. amfphp 2.0 will be amfphp 1.9 + JSON and possibly XML-RPC) If you run into any issues, please either: - Create a minimal test case which shows the reproducible bug, then send it to me. - In gateway.php, uncomment $gateway-logIncomingMessages and logOutgoingMessages, create

2006/12/19, Jamie O [EMAIL PROTECTED]:
For the stand-alone basic .mxml I used a copy of the basic example
Renaud gave - with a different URL for the gateway which is located on
a separate server. For the cairngorm / FDS version, here are the
changes I made to the default FDS .xml files
1) In services-config.xml, add the service to the services section
beneath the 4 service include path links add the service:
services
service-include file-path=remoting-config.xml /
service-include file-path=proxy-config.xml /
service-include file-path=messaging-config.xml /
service-include file-path=data-management-config.xml /
service id=amfphp-service
class=flex.messaging.services.RemotingService
messageTypes=flex.messaging.messages.RemotingMessage
destination id=AMFPHPDestination
channels
channel ref=my-amfphp/
/channels
properties
source*/source
/properties
/destination
/service
/services
2) In services-config.xml, Add to the channels section add the
following channel:
channel-definition id=my-amfphp
class=mx.messaging.channels.AMFChannel
endpoint
uri=http://externalURLaddress/amfphp/gateway.php;
class=flex.messaging.endpoints.AMFEndpoint/
/channel-definition
3) Here's the services.mxml remote object:
cairngorm:ServiceLocator
xmlns:cairngorm=com.adobe.cairngorm.business.*
xmlns:mx=http://www.adobe.com/2006/mxml;
mx:RemoteObject
id=roAMFPHPService
destination=AMFPHPDestination
source=AccountService
showBusyCursor=true
mx:method name=checkLogin /
/mx:RemoteObject
/cairngorm:ServiceLocator
4) And the relevant parts of the login delegate which calls:
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.remoting.RemoteObject;
public class LoginDelegate
{
protected var service:RemoteObject;
protected var responder:Responder;
public function LoginDelegate(p_responder:Responder)
{
trace(LoginDelegate::constructor);
responder = p_responder;
service = ServiceLocator.getInstance().getService(AMFPHPDestination)
as RemoteObject;
}
public function CheckLogin():void {
trace(LoginDelegate::CheckLogin function - + p_AttemptedUser.UserID);
service.addEventListener(ResultEvent.RESULT, CheckLogin_onResult);
service.addEventListener(FaultEvent.FAULT, CheckLogin_onFault);
service.checkLogin(UsernameTest, PasswordTest);
}
protected function CheckLogin_onResult(event:ResultEvent):void
{
trace(LoginDelegate::CheckLogin_onResult - Output);
trace(event.result);
responder.onResult(new ResultEvent(ResultEvent.RESULT, false, true,
event.result));
service.removeEventListener(ResultEvent.RESULT, CheckLogin_onResult);
service.removeEventListener(FaultEvent.FAULT, CheckLogin_onFault);
}
And I receive the error Destination 'AMFPHPDestination' must specify
at least one adapter. The php service isn't anything special, just
give username / pass, validate in query to the mySQL DB and return a
specific data element if valid. I know from ServiceCapture and the
other version that I don't have an issue on that side.
Much thanks!

That's because you're getting a fatal error from PHP, and therefore the

install Charles debugging proxy or ServiceCapture to read the error, or

Re: [flexcoders] Re: SEO Compatibility
Saying you shouldn't use Flex for content-focused website is going a little bit over the edge IMHO. I think we all definitely agree that for 100% content-focused sites, you should use HTML, and for 100% data-focused sites, you should use Flex. However in between those extremes, you can still use Flex and get your data indexed. For example, if you're going to create a blog in Flex, you are probably going to use some sort of ready-made blogging engine and plug it into a Flex front-end, using whatever means you feel are right (for example, using XML-RPC if you're using WordPress). Well, blogging engines create RSS feeds, and Google will index an RSS feed just fine. Then it's a matter of adding a link to the RSS feed in the HTML for the Flex app. Similarly if you create a message board. While I'm not convinced creating a blog or a message board interface in Flex is smart (I would advise against it personally), if you want to do it, you have options for getting it indexed. You don't have to sound angry when you're talking about it. It just sounds like you're trying to say PEOPLE, DON'T USE SCREWDRIVERS, YOU CAN'T DRIVE NAILS WITH THEM. Dude, that's why we have hammers. Patrick Doug McCune a écrit : How about this one as an example: the Adobe Restaurant Finder sample app, with the Recent Reviews page in particular. The app is here: http://examples. adobe.com/ flex2/inproduct/ sdk/restaurant/ recentReviews. html http://examples.adobe.com/flex2/inproduct/sdk/restaurant/recentReviews.html If you look at that app you can see user submitted reviews of restaurants. For example, there's a review of Addis Red Sea and the reviewer mentions E. Coli in the review. If anyone did a search for Addis Red Sea and E Coli this page would never come up. The only possible way to get the site to appear in search results would be to publish an alternative HTML version of all the reviews. And in fact a complete Google search for everything on examples.adobe. com shows that you can't find anything useful: http://www.google. com/search? q=site:examples. adobe.com+hl=enlr=filter=0 http://www.google.com/search?q=site:examples.adobe.com+hl=enlr=filter=0 Yes, the Restaurant Finder app wrapper HTML page is indexed, but that's useless. Now, a Google search for ecoli on Yelp turns up tons of user-submitted results: http://www.google. com/search? hl=enlr=q=site%3Ayelp. com+ecoli http://www.google.com/search?hl=enlr=q=site%3Ayelp.com+ecoli The Yelp team would never give that up. They simply can't do Yelp in Flex because they'd lose the search engine indexing. Now, I'm not saying that this is a huge problem. All it means is that at the moment Flex is not the answer for many websites. That's OK, Flex is still great at what it does well. But if you want any of your dynamic content indexed by search engines Flex is not the way to go. And it's not a matter of just thinking about how to include keywords. Flex just simply isn't an option, nor does it need to be, for websites like this. Use Flex for what it does, but trying to make a website in Flex that needs to be indexed by a search engine simply isn't an option at the moment. And this example of the restaurant review stuff is a typical example of tons of other types of websites that shouldn't be done in Flex. Blogs, news sites, message boards, the list goes on and on. But if you're doing some stuff that needs data visualization or you can do without search engine indexing, then by all means use Flex. And I say this as a HUGE fan of Flex. People just need to use it for what it's good at.

Re: [flexcoders] Spell Checker
As far as the PHP side of things goes, there are functions already
built-in for that. You can read about it here:
http://www.zend.com/zend/spotlight/spellchecking.php
You could call php to do the spell check every so and so seconds or
after every space or with a button... Really depends on what you want.
As for the backwards looping use String.lastIndexOf(' '). For the
formatting take a look at setTextFormat.

I've seen the Component on the Flex Exchange, and it's not going to
meet my needs, primarily because my app won't always have an internet
connection to use the Google API. Also, I need the custom dictionary
to be in my DB so users have access to it regardless of what PC they
are using.
So, I'm asking for some advice and ideas on creating my own Spell
Check feature using PHP and MySQL.
I've been thinking about this in theory, and here are my initial
questions where I would like feedback.
Do I call a remoteObject after every keystroke to compare against a
database table of words or do I wait until all the fields are filled
out and then have the user click a button to Spell Check the fields?
Maybe both?
How efficient is this going to be with say 100,000 words in the word
list to check against?
What about integrating a PHP spell checking function?
How do I loop backward until I find a space so I am only checking the
last word?
How to allow the user to add words not in the standard dictionary to
their custom table, from where they are in the application?
How do I then set the style of the last word to red underline, change
the text color, or some other visual representation to note an
incorrect word?
If using a Spell Check button, I'd like to change the tab color to a
different color, if there are spelling mistakes in fields on that
tab. I'd also like to highlight fields where there are spelling
mistakes.

Hi Robin,
I have good news :), both of these issues should go away by setting a
single attribute on your WebService object. Try setting
makeObjectsBindable = false. This will cause Flex to deserialize your

ObjectProxy and ArrayCollection instances.

If you want to get a description of a method and it's arguments without looking at the class itself, add JavaDoc to the method and you should see it in the new Service Browser. - _authenticate is dead, as a side-effect of the removal of the methodTable. You can secure methods by creating a special function called beforeFilter($methodName) in your class and return false to stop a method from being executed. (the _ and the beforeFilter are the conventions used by CakePHP, so I figured I'd use those instead of rolling my own). - Circular references in AMF0 and AMF3 should now work. Class mapping code has been ported to the AMF3 code also. To use remote class mapping, use registerClassAlias or the [RemoteClass] metadata tag, then read the instructions in advancedsettings.php - Returning a mysql_query will now return either an Array or an ArrayCollection depending on the setting in gateway.php. Other database types are currently unsupported in AMF3 mode (they will be supported as soon as I am sure the AMF3 code is perfect). - You can send ByteArray, ArrayCollection and ObjectProxy instances as arguments to remote methods. You will receive the result as a string, as the inner array and as the inner object, respectively. Currently there is no way to send back these types to Flash, but there will be in the next version. - /browser now brings up the brand spanking new Flex 2-based service browser. You can test methods directly through it. If the method returns an array or arraycollection, the browser will attempt to show it in a datagrid (sweet). Please feel free to modify servicebrowser.mxml (it's very spaghetti-code-ish, but it works). You will need the Adobe corelib to compile (google for the link) Limitations/things to keep in mind: - MySql works but not other databases - You can use a JSON string for arguments in the service browser. However you must wrap object keys in quotes (a limitation of Adobe corelib). - Paged recordsets don't work anymore - Only tested in PHP5. PHP4 might show issues with circular references. - Calling two methods on a remoteObject one after the other (during the same frame) might not work. - Charles and ServiceCapture have some issues with AMF3 handling. You might see strings which seem out of place in your output while it works fine in Flash. I will notify the people involved. You might want to set PRODUCTION_SERVER to true in gateway.php if this is a recurrent problem, in the meantime. - If you need to send to Flash a class and want it to be mapped to a class in a package, you need to add a key to the class called _explicitType with a value of com.mypackage.TheClass and use registerClassAlias or [RemoteClass] as usual ( a limitation of php not supporting packages) All that being said, I need testers. Please download it here: http://5etdemi.com/uploads/amfphp-1.9.alpha.zip (although it states it is amfphp 1.9, there will be no amfphp 1.9. amfphp 2.0 will be amfphp 1.9 + JSON and possibly XML-RPC) If you run into any issues, please either: - Create a minimal test case which shows the reproducible bug, then send it to me. - In gateway.php, uncomment $gateway-logIncomingMessages and logOutgoingMessages, create an in and an out folder and run it again. Then send the log files (*.amf) to me. Please send the feedback to pm AT 5etdemi DOT com. I am confident it should be pretty stable, as most of the new code is lifted from Fluorine, but you never know. Once I am 100% sure the amf 3 code is bulletproof I will release another version with some publicity on the blog and the homepage (currently keeping the new code low-profile). Thanks, Patrick
Re: [flexcoders] webservices and Flex 2
Hi Robin, Whether you're using RemoteObject or WebService, the point of using either is _not_ to have to do that kind of serializing/deserializing. So it's all built-in, and it's all done behind the scenes, at the player level in the RemoteObject case and at the ActionScript level in the WebService case. As a side-note, if you're going to be creating web services (as opposed to using a ready-made one), you might as well use RemoteObject; WebService and RemoteObject do the same job, but SOAP is very verbose while AMF has a much smaller footprint, so RemoteObject usually beats WebService speed-wise by a large margin.

Re: [flexcoders] Re: SOLUTION: Unable to bind Warning
As long as we're on that subject... I've added a new setting to amfphp, which is: $gateway-setAmf3RecordSetFormat(Array); Which can also be set to ArrayCollection. I have yet to implement it, but does this sound like something useful to you? Patrick lostinrecursion a écrit : It's interesting how AMF does not provide the same wrapper functionality as HTTP and WEB services. Reason being, when using the standard CFC to AS Class mapping features of Flex 2, you could certainly benefit from such an automated conversion. For example, when passing data to Coldfusion as an ArrayCollection and getting it back as an Array. Nice find. I was having a similar issue.
Re: [flexcoders] Loader + RemoteObject's
The NetConnection class doesn't receive progress information from the player, unfortunately, so it would be impossible AFAIK to get progress information from it. The only way you could attempt to achieve this is using the Socket class and manually encoding and decoding the AMF3 packets while sending progress information. Seems like a major pain to attempt, though.

I just need an example -- please- also measureWidth requires anti-alias
not set to null, how does one set that
correctly? I wish Adobe would add more examples in the documentation
about textfields, i mean look at the posts about textfields, wordwrap
etc. a lot of people have questions about these new tools and not
everybody migrated from flex 1.5, like me. There's a bunch of stuff
that should have simple examples. Actually shouldn't every class have
examples, in a perfect application development world? UITextField has
no examples. Will there be more actionscript examples in flash
because i notice that most examples in flex documentation are reserved
for mxml than AS.
I really miss the old days of mytextfield. _width... I'm done venting

Re: [flexcoders] Flex eye candy and memory consumption
From what I understand, what Ted means is that the player asks for such and such amount of memory when it requires some, and may or may not give it back when it doesn't need it anymore. So the worst case scenario is that the memory consumed by the player is the maximum amount of memory since it was loaded (the ceiling). That's the worst case scenario however. In my personal tests in Firefox 2 when the totalMemory goes down the memory consumption in Firefox also goes down a few seconds later. I am talking about an app here which can take a full 100MB of memory in a few seconds then release it in a few more seconds later (lots of BitmapData manipulation and Loaders). I think what Ted means is that you can't expect the garbage collector to collect when you want it to and you can't expect that when the garbage collector is run the memory will go down immediately, although it should eventually based on the player's and the browser's memory allocation heuristics. As for the effects though, I think it's possible that the instance of the effect is still in memory after being used, but I doubt that's the actual cause of the problem, since the effect doesn't really contain all that much stuff in it. It's possible however that once the effect is played it doesn't completely clean up after itself. Things to look out for include filters, cacheAsBitmap set to true, wipe effect masks which linger on, etc. For example, if you use have a tween from a blur filter to set blurX from 4 to 0, you have to make sure after to set filters to an empty array and set cacheAsBitmap to false (filters automatically set cacheAsBitmap to true). You'd really have to look at the source code of the actual effect you're using to see how it works internally and see if it's doing the kind of cleanup you want it to do, and if not, then perhaps you should try to extend the effect to do the garbage collection yourself. Here's my advice however: don't bother doing this unless you're in the final stages of the application development. 10 MBs lingering about is not going to make your app crash. I would expect that at the end your app will have more important memory bottlenecks than this one, like heavy use of Repeaters, too much components initialized, etc. Patrick coderjun a écrit : Hello, I was wondering if anyone has run across memory consumption issues when using some of the eye candy in the Flex framework. Here are a couple of examples of what I am referring to: 1. The translucent overlay on the rest of the app when using Alert.show in modal mode. (vs. using the flag Alert.NONMODAL) 2. Using mx:WipeUp/ and mx:WipeDown/ for the inEffect and outEffect of a component. I've been tracking the effect of using these effects by watching Task Manager|Mem Usage for the firefox.exe process right before and right after these effects run. We're talking 4-10MB of memory consumed each time these effects are run. (I know because I've done the process of tracking with the same code and the effects turned off resulting in 300KB-1.5MB) . My concern is that: 1. I can't programmatically (minus the unsupported tip given to us by gskinner http://www.gskinner .com/blog/ archives/ 2006/08/as3_ resource_ ma_2.html http://www.gskinner.com/blog/archives/2006/08/as3_resource_ma_2.html) force the Garbage Collector to run. 2. Since I can't force the Garbage Collector to run, the comments by Ted Patrick on Flash Player memory management and releasing memory back to the OS is highly concerning. (http://tech. groups.yahoo. com/group/ flexcoders/ message/48219 http://tech.groups.yahoo.com/group/flexcoders/message/48219 | http://tech. groups.yahoo. com/group/ flexcoders/ message/48330 http://tech.groups.yahoo.com/group/flexcoders/message/48330) I understand that effects would consume memory to run, but I don't like thinking that once the memory has been allocated I have no control on if it will be given back to the Operating System. I've tried leaving my app open all night to see if the memory allocation would go down and it doesn't. (You would think since the effects were long done it would) Also, the app I'm working on is one that needs to run all day, so closing and reopening the browser is not an option. Has anyone noticed what I've noticed or have any insight on how to use effects without increasing the footprint so? -Jun
Re: [flexcoders] vertically centering text
If your item renderer was a VBox you could set verticalAlign to middle.
That might slow your app down if you have a lot of rows with VBoxes
versus just plain Components.

Since there is also a image field, the height of each row is a lot

I can't find any property that seems to apply. I know there is a

Re: [flexcoders] AMFPHP / databinding nested arrays

carkraus a écrit :
Hi there,
I guess this is a typical newbie question, maybe someone could kindly
direct me to a tutorial or sample:
I try to bind e.g. using a charts control to a nested array I receive
from an AMFPHP service.
On the php side I have as an example:
$outputArr[] = array('day' = 'Mon', array('start' = '100', 'end'
= '300'));
$outputArr[] = array('day' = 'Tue', array('start' = '250', 'end'
= '600'));
$outputArr[] = array('day' = 'Wed', array('start' = '500', 'end'
= '600'));
return $outputArr;
..which will deliver the data correctly as I can see from the flex
debugger.
In flex I have eg.:
mx:series
mx:ColumnSeries xField=day yField=??? /
/mx:series
Now, how do I access e.g. the value 'start' to use it for databinding?
Well, 'day.start' does not do the trick : )
I had similar probs using XML for binding, where I wouldnt be able to
access sub-children?
Do I have to somehow wrap the server response into an actionscript
object which I'd have to manually add properties to?
Any hint greatly appreciated! !

[flexcoders] Can't get focusRoundedCorners to work on ButtonBar
I'm trying to accomplish the following: have a ButtonBar in which each
of the buttons has rounded corners (unlike the default where only the
left most and right most buttons have some rounded corners). I've been
playing with this for a while now, and I can't get it to work. Here's
some minimal code:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns=*
layout=vertical
mx:Style
ButtonBarButton
{
focus-rounded-corners:tl tr bl br;
corner-radius:10;
}
.ButtonBarButton
{
focus-rounded-corners:tl tr bl br;
corner-radius:10;
}
/mx:Style
mx:ButtonBar
focusRoundedCorners=tl tr bl br
dataProvider={vs}
firstButtonStyleName=ButtonBarButton
buttonStyleName=ButtonBarButton
lastButtonStyleName=ButtonBarButton
/
mx:ViewStack
id=vs
mx:Box label=1
mx:Button label=button 1 /

mx:Box label=2
mx:Button label=button 2 /
/mx:Box
mx:Box label=3
mx:Button label=button 3 /
/mx:Box
/mx:ViewStack
/mx:Application
As you can corner-radius works correctly but focusRoundedCorners fails
in all circumstances. Some of the code here is redundant or
non-sensical but it's just to show that I have tried everything I
could think of. Any ideas?
