Re: [flexcoders] unable to bind to property warnings binding to read-only properties
And you're not getting foo is not an IEventDispatcher? What's your

testbed code at work, so I can't verify it for myself :)
Most intriguing though.

Interesting. Actually, I just did this:
[Bindable(event=foo)]
public function get start():Date {
return _start;
}
without deriving from EventDispatcher (unnecessary, since I'm not
dispatching anywhere), and that also worked. So perhaps that's the
best approach, assuming the overhead of the [Bindable] tag is pretty
minimal.
Without knowing much about the internals, I can't be sure whether/how
the warning could be more discriminating or informative, although I
would think the runtime could tell that the property is read-only and
not the root of the expression.
Thanks.

This works as you'd expect it to, so it is possible to bind to

long
as it's an IEventDispatcher.

*Subject:* [flexcoders] Problem editing custom object in DataGrid
(itemEditEnd method, cannot get data)
Hi, I've created a MultiLanguageString object which contain an array of
language codes and text value (e.g. [en] = Hello, [de] = Guten tag etc.)
When editing in a DataGrid you always see the current selected language
since MultiLanguageString's toString() method returns the internal arr[
currentLanguageCode ] text.
However, on edit end I got this error saying String cannot be converted to
MultiLanguageString (Type Coercion failed), so I figgured I'd have to create
my own itemEditEnd listener and prevent the vent from reaching the dataGrid
there.
This works fine.
However, I'm unable to get the data somehow (all I get is the original
data, unedited) .. I see DataGrid uses the event.itemRenderer.data, but when
I look that up I only see the old data. Same for all other properties on the
event which contains the data.
Should I take a different route here or is it solvable this way?

[flexcoders] Flexlib SuperTabBar, ButtonScrollingCanvas, and dataProvider
I am attempting to create a Flex component based on a combination of
Flexlib's SuperTabBar and ButtonScrollingCanvas components. The
intended result is to be a component that looks and behaves similar to
the tab bar, described in SuperTabNavigator_Sample.mxml as
the example using just the SuperTabBar without the entire TabNavigator
component. In the compiled SWF, this scrolling tab bar example is
displayed at the bottom of the browser window.
However, I am having troubles getting the dataProvider to work
correctly. The only method that has been successful in the setting the
SuperTabBar's dataProvider correctly has been when using an mxml
dataProvider tag with string objects populating the tag.
If I attempt to create an array of those same strings and
programmatically pass this array to the dataProvider setter, by either
calling the setter or by using the dataProvider tag
attribute ...dataProvider={theArray}... the result, as displayed in
the component, is a single blank tab.
Any suggestions on what I might be doing wrong?
[flexcoders] 5,000 record dataset needs love
Dear Super Smart Flex Developer Mailing List, We are currently having major issues processing a dataset that is essential for our skunkworks web site. The dataset is stored as JSON, consists of 5000 records, and has numerous strings. It is 1.4mb uncompressed / 85kb compressed. Processing the data, which involves creating a custom object to hold it, currently takes a much as 60 seconds. We are in the process of attacking this beast to make it run faster, and we are considering the following approaches: 1. Create an index for repetitive strings within the dataset to avoid repetitive strings because integer assignment is faster than string assignment (we assume). 2. Try substituting XML for JSON (no idea if this would be faster or not). 3. Attempt to deliver an actionscript binary blob to the application from PHP (not even sure if that's possible... ASON?). 4. Create a compiled swf with our data postprocessed and attempt to access it (again, not sure if that's possible). 5. insert your solution here Your expert, snarky, helpful advice is much appreciated, Tom

[flexcoders] Coldfusion 8, BlazeDS, Flex Builder 3
Hi, I apologise if this is a simple question but it's got me stumped. I have a development server on my local network running CF8. I've installed BlazeDS (so that is shares the same JRun as CF). I've set up a destination in C:\CF8\wwwroot\WEB-INF\flex\message-config.xml. My web root (IIS) is on a different drive. What I can't figure out is when I create a new project in FlexBuilder (Eclipse Plugin). What do I set the root folder, Root URL and context root to as the root folder expects to find message-config.xml. Can I just set up a copy of message-config.xml in a web accessible folder so that flexbuilder can pick up the destination (I know that CF/BlazeDS won't reference this config file) Thanks!

Once you've done that, make sure it's mouseEnabled false, and that should do it. If you make it a modal pop-up, you'll have some kind of mouse blocker layer below it, preventing the rest of the app from getting mouse events.

Filtering however might not be very responsive. I think the following options are available: - Display all records in the datagrid and use a regular filter (too slow I think) - Display all records and filter with breathing space by using multiple frames (might be fast enought) - Display only the selected records. Each selection change triggers a call to the server (no filtering done on the client) What option do you think is best (or do I have any other options)? Greetz Erik

I'm assuming that currently executing code is not suspended so that an asynchronous event can be handled, but I was curious as to exactly when asynchronous events are serviced. Thanks. Currently executing code will never be suspended in a single-threaded environment, which is what Flash is. The asynchronous events are handled when your application is idle. Although I don't know how exactly the Flash Player does this, I imagine that events are pushed into an event queue from where they are processed one by one. So at some point, when your network call has returned, its event might go into the queue and from there it might get dispatched and subsequently handled by your app. The frame rate has nothing to do with event processing.

1) don't bind to {foo.bar}, bind to {getBar(foo)} or {foo.getBar

adding the getBar method either to the MXML component trying to

2) declare the bar getter function as [Bindable] to a made up

[flexcoders] ScriptTimeOut Issue
Hi All, I am opening an html popup with a TextEditor using javascript from my flex application . When the user fill in the textarea and click the submit button in the Texteditor, javascript closes that window and returns the value back to the flex .( using FABridge ) . The issue is that if the javascript window is used more than a minute a runtime error (script is executed more than the default time out period.) I set the scriptTimeout property to the maximum value ( 60 seconds ). When the javascript popup is closed , it is calling public metthod in thr flex application. Is there any workaround for this . What i want to achieve is to keep the external html window remain open as long as i wish and to call a method in the flex when it is closed. Thanks in advance Subeesh

[flexcoders] Re: Securely Interfacing Between Flex and Databases
Kenny, are you saying you want to implement security *within* your Flex app? I think you'd have serious security holes with that (your decompilation concern, for one). Typically security would be handled at the client-server level, by hosting your SWF on a server that has been configured to accept connections over https (e.g., https://myserver.com/myapp), connecting to your app via HTTPS from a browser, and designing your Flex app to connect to other servers over HTTPS as well. Web servers and browsers already have built-in implementations of RSA, SSL/TLS, and the other industry standards mentioned in other posts so there's really no need to implement them yourself. The same SWF (with certain design considerations taken into account, of course) can be accessed on the web non-securely (over HTTP), or securely (over HTTPS). HTH, Doug --- In flexcoders@yahoogroups.com, kenny14390 [EMAIL PROTECTED] wrote: So the bottom line is to use an algorithm like RSA? To take a much simpler example, if the Flex app receives the encrypted data 1234 and it wishes to use that data, it must first decrypt it. So it performs the decryption in some AS and now you have the decrypted data that you wanted. My question now is, if someone decompiles your app they can see your decryption method and thus decode the data on their own. Nothing is private in the Flex app due to the decompilation concern. Regarding SSL, I suppose this is out of the question if we're talking about a Facebook application. I don't have much control over their security. --- In flexcoders@yahoogroups.com, andrewwestberg andrewwestberg@ wrote: I think you're confusing simple secret key encryption (DES, AES, etc..) with public/private key encryption (RSA).

In public/private key encryption, a message you send to the server is encrypted by a public key and can ONLY be decrypted by a private key known only to the webserver (the certificate you bought from verisign, thawte, etc...)

While waiting, if any events are triggered, execute all registered event listeners. 3.At frame-render time, check if the screen needs updating. The screen needs updating if any of the following is true: * Frame 1 contains changes to the contents of the Stage made manually in the Flash authoring tool. * Code in Frame 1's frame script created new visual content or modified existing visual content. * Code in a listener function executed during Step 2 created new visual content or modified existing visual content. 4.If necessary, update the screen to reflect all changes detected in Step 3. 5.Repeat Steps 1-4 --- In flexcoders@yahoogroups.com, Manish Jethani [EMAIL PROTECTED] wrote: On Wed, May 21, 2008 at 7:48 PM, Paul Whitelock [EMAIL PROTECTED] wrote: When a response is received from a web service (for example), when is the listener code executed?

Currently executing code will never be suspended in a single-threaded environment, which is what Flash is. The asynchronous events are handled when your application is idle. Although I don't know how exactly the Flash Player does this, I imagine that events are pushed into an event queue from where they are processed one by one. So at some point, when your network call has returned, its event might go into the queue and from there it might get dispatched and subsequently handled by your app. The frame rate has nothing to do with event processing.

as http requests and redirects them to the tomcat..
When i add the secure channels ( amf and http) in my default-channel list
and i have included the trace target in my main mxml File..
It shows that it is pinging the my-secure-amf endpoint and doesn't get
any response..( i get the same when i connect using http i.e, from the
intranet)
Now when i remove the secure channels from my default channel list and
regenerate the .swf files (i have the servlet mapping configured to
regenerate them if they don't exists already..) i can connect to the
web app from intranet which uses my-amf channel.
How ever when i try to connect over https the trace shows it is not
getting any ping response from my-amf channel..

[flexcoders] Re: Dynamic HTTPService Request
Try doing your HTTPService request in ActionScript instead. e.g. var params:Object = new Object(); params.parameter1 = value; params.parameter2 = value2; var myService:HTTPService = new HTTPService( /myuri ); var at:AsycToken = myService.send( params ); at.addResponder( new Responder( resultHandler, faultHandler ) ); You can also explicitly put parameters on the URL e.g. /myuri?parameter1=value. With IE and browser caching, you may want to arbitrarily include a timestamp parameter. Not sure if this is always needed. e.g. /myuri?time= + ( new Date() ).getUTCMilliseconds() Haven't done alot with HTTPService (mostly RemoteObject) and I John Wayned the code examples so you should probably double check but generally you get more flexibility in ActionScript. - Todd --- In flexcoders@yahoogroups.com, kenny14390 [EMAIL PROTECTED] wrote: If I have a variable number of things to POST to a PHP page using HTTPService, I need to use mx:request to get those things over.

[flexcoders] Flash-AIR-PHP drag and drop Hybrid
Hi Folks, The application I am working on has a requirement to support drag and drop, from client to server. Currently, we can only support this by using a signed Java Applet that provides the drop box that allows the EU to drop files from the local file system. As a result the files are transfered to the server (PHP) and the Java Applet informs the flash app that a transfer is in progress (providing taskID), and the flash app polls the server for status on the task. Once completed the UI updates to reflect and notify the user of the change. Is it possible to do the same with AIR? We dislike the need to present the EU a drop box and would love it if we could make the drag and drop seamless with AIR-Flash-PHP. I am thinking this could be performed by: - AIR app Drag Manager installed on client PC (launched when the flash app is initialized) - Flash or AIR app detects the client is trying to drag a local asset onto the flash app (not sure if this is possible) - AIR app responds by sending file to the server PHP and passing a taskID to the flash app for it to track - Flash app polls the server until the taskID to complete, displaying some transfer progress Any comments, suggestions much appreciated!

Yes, so in your while waiting time, if you make a network call --
say you download an XML file -- and the call returns (asynchronously)
during that time, then you'll get the event for that before you go to
step 3. i.e. it won't wait for the next frame before you can process
the event.
Try this test:
?xml version=1.0?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns=* mouseMove=trace('mouseMove', getTimer())
enterFrame=trace('enterFrame', getTimer())

As you move the mouse, the event is processed. It doesn't wait for the
next frame before you can get the event.

Either the Flash Player is using the browser's cache or it isn't. If

I think you should write your own component that grabs the actual

// Setter method in your custom component.
public function set url(value:String):void
{
_url = value;
var image:Loader = cache[_url];

RE: [flexcoders] Re: How to use WebServices in Flex 3?
To be clear, in Flex you will be 'consuming a web service, not creating one. Consuming a simple webservice in flex is pretty easy, the examples in the docs are pretty clear and there are other examples around (I have on on www.cflex.net http://www.cflex.net/ ). One benefit of the generated code, or of using the same approach is that you wind up with strongly typed Value objects to work with in Flex. This is the most performant option, noticable if you have many complex item renderers displayed at any one time. If your UI is not so dense, then simple access of the returned XML works just fine.

Re: [flexcoders] 5,000 record dataset needs love
Figure out where the real bottleneck is. I just did a demo app that loads over 35,000 records from an uncompressed CSV file (over 2 meg). It's all doable, you just have to figure out which part is slow. You basically have these possibilities in terms of what's taking the most time: 1. Loading 2. Parsing 3. Rendering If the time is spent loading the file then simply compressing the file and sending the compressed version across the wire might help. Using a binary protocol like AMF will get you the best transfer speed though. I actually like CSV files because they're small and easy to export from Excel. If parsing the data is taking a long time then examine what you are doing as you parse the data. Moving away from JSON will likely save time, since JSON has to be decoded and processed even before your own processing happens. I'd guess that XML would be faster than JSON, although I don't know that. If you use AMF then you mostly get this step for free, since AMF decodes as native AS3 objects (although that takes time, but it's fast). Assuming you're doing the conversion to your VOs manually, a few tips: - the big thing here is make sure that your VOs do not use databinding. If your VOs are Bindable objects or have bindable properties you will want to remove those and control the binding manually. You can still have bindable properties, but you should control the bindings yourself. - Do not parse the records into an ArrayCollection. Parse them into an Array. If you use addItem() of an ArrayCollection then the collection dispatches an event every time you add an item. Instead, parse into a simple Array, and if you want to use an ArrayCollection in your app then create your AC after the parsing and set the source of the collection. - Do the parsing in batches. If you can split up the parsing then you can keep your app UI from locking up. I usually parse around 500 records at a time This won't speed up the processing (in fact, it will add to the total time a tiny bit), but this lets you show progress as your are parsing. I have my parsers dispatching progress events as they process batches and I show that progress in a progress bar. And if the most proessing time is spent after you have your data loaded and parsed then figure out what you're doing to render that data. Try to show less items, or group the items, or something. I assume you don't need to create 5,000 renderers all at once. Use the list controls to take advantage of item renderers, etc. In my example app that loads 35,000 records the loading of the 2 meg file takes about 10 seconds. Looping over all the records and turning them into AS3 value objects takes about 2-3 seconds. Then post-processing those records to group them takes about 10 seconds (this loops over the entire dataset and does some aggregation calculations). So all in all that takes almost 30 seconds, but it's 35 thousand frickin records and during the entire process the app is responsive and progress is shown for each step.

myLoader needs to be an instance variable instead of a local one.

function xmlLoaded(event:Event):void

myXML = XML(myLoader.data);
trace(Data loaded.);
}
And I want to read the XML file into a XML object in Flex, so that I
can access different elements of it easier. But it is throwing up two
errors when I try to compile it:
1120: Access of undefined property myLoader.
1120: Access of undefined property xmlLoaded.
What am I doing wrong? Do I need to import any special things first? I
am still pretty new to Flex...

[flexcoders] Re: How do I use URLLoader?
Hmm, I tried that but it didn't work... I previously tried these as well but they didn't do it, nor did the import flash.net.* ... hmmm import flash.net.URLLoader; import flash.net.URLRequest;
[flexcoders] Flex automation - AutoQuick sample application
Trying to get the AutoQuick automation sample application running on my own and for some reason the automationManager is always null. Line 355 in the AQAdapter. Anyone know why this might not be getting initialized properly? Feel like I followed the instructions pretty well... http://livedocs.adobe.com/flex/3/html/help.html?content=agents_3.html Thanks, - Todd

Would it be possible to use that function to change cell's font color based on a numeric value in the cell? Thanks
RE: [flexcoders] Re: Is it possible to invoke a AMF call just before browser close?
Also, watch out for the fact that BlazeDS automatically resets the session when
it is invalidated, so if you do session.invalidate() within a remoteobject
method on the server the current session will be invalidated but a new, empty
session is automatically regenerated (i.e. request.getSession(true)). This is
done in case there are any further messages in the current batch being
processed that could potentially blow up during processing if there's a
dependency on the session.
Using the trick Mete mentions below, you can call into your swf and invoke
disconnectAll() on your channelSet. This will inform the server that the client
is going away. The default behavior on the server in this scenario is to leave
the current session in place in case the user has other apps/pages running that
depend on it. But you can trigger a clean session invalidation (that will not
create a new session) by adding the optional 'invalidate-session-on-disconnect'
config setting to your endpoint. Eg.
channel-definition id=my-amf class=mx.messaging.channels.AMFChannel
endpoint
url=http://{server.name}:{server.port}/{context.root}/messagebroker/amf;
class=flex.messaging.endpoints.AMFEndpoint/
properties
invalidate-session-on-disconnecttrue/invalidate-session-on-disconnect
/properties
/channel-definition
When you handle a click of your logout button, you could just invoke logout()
on your channelSet which will invalidate your server session, clear out any
authed Principal, and leave you in a state where the user could log back in if
they wished.

I'd try onunload and onbeforeunload events to see they help. If that
doesn't help, I'd try putting up an Alert box before making the AMF
call to make sure AMF call is made before the browser is closed.

Hi,
I am trying to invalidate a session by explicity invoke a AMF call
when the user click logout or closing the browswer.
By ExternalInterface, the CLOSE event is capture within the FLEX
correctly. But by tracing in the debugger, if a AMF is invoke upon
this, the call did invoke but the AMF call is not sent to through the
FDS, I wonder if the application is being killed before the FDS
successfully sent the request.
Is it not a good idea to invalidate a session in this way? Any
Flexpert suggestion? :
