[flexcoders] Re: Memory issues ... garbage collection only running in IE (not FF or Safari)
My original mxml was a bad example I guess. In my application, which
is a Flex app that has its own windowing (exactly like Windows)...when
I add and create Windows and close them, the browser CPU memory always
increments (except for IE when I minimize the browswer window and
memory is restored). When using System.totalMemory, I see some memory
gets cleaned up but not all of it and if I open and close the same
window multiple times, it is inconsistent to how much memory is given
back to the Player, but either way it continually increments. I use
weakReferences everywhere and call removeAllChildren() on the toplevel
containers and set the viewComponent to null when removing the
Mediator from the Facade (PureMvc). But yeah, when using Profiler,
which forces a gc(), all memory is correctly restored back the player.
Just not in runtime. The hunt continues...

[flexcoders] Re: Memory issues ... garbage collection only running in IE (not FF or Safari)
Thanks for the great advice so far...so what is the best way of
freeing Images for gc()? I have a DataGrid that has an itemRenderer
with a mx:Image/...if I have a dataProvider ArrayCollection (where
each records has a URL that the Image uses)...does simply setting the
dataProvider to null take care of marking the image for GC? And
anything I have a Bitmap for? Simply setting to null.
Thanks again.

If your app creates lots of stuff, you'll create a high-water mark

Images are known to easy ways to set that high-water mark pretty high.
In general, the answer is to re-use instead of re-create, and only
create what you need when you need it.

e_baggg,
You're not the only one. We're experiencing very similar
problems. Our app just keeps gobbling memory until the browser
crashes. We've had to resort to calling dispose() explicitly on every
mx:Image and bitmap we ever instantiate, and explicitly calling
removeAllChildren() on every contaniner before navigating away from
anything. Helps a little. I'm going to look in to the link you
mentioned. Maybe that will help us a little more than it has for you
(fingers crossed).
Let us all know if you find anything else out.

[flexcoders] Re: Socket HTTP/1.1 connection not closed even after Response is sent
I finally got it working. No matter what, the Flash player makes a request to port 843 asking for the cross-domain...even if you call Security.loadPolicyFile(). I found a source example where a Java socket (which I kicked off in a shell script) listens on port 843 and returns the policy file. So, I therefore never need to call Security.loadPolicy(). Here's the link to that library. You need to make sure this port is open on your firewall which is easily testable with a telnet call. This port 843 method is actually the recommended way to do it according to Adobe. http://www.flash-resources.net/ --- In flexcoders@yahoogroups.com, Josh McDonald [EMAIL PROTECTED] wrote: Let us know how it works.

[flexcoders] Re: Socket HTTP/1.1 connection not closed even after Response is sent
I am doing hand-rolled GETs because Flex (HttpService) cannot pass headers (ie jessionid). Thus, I need to open my own flash.net.Socket and write/read the request/response manually. It works great with Digest authorization except for this policy issue. I suppose I can get around this making the login page a JSP and make the redirect go to the swf html page...and from there use HttpServicebut still I hate hacks. Such a shame this policy stuff is such a nightmare. I followed the Adobe docs exactly and I still have issues. I'll work on this more and report back anything I find. --- In flexcoders@yahoogroups.com, Josh McDonald [EMAIL PROTECTED] wrote: Also, maybe we should look at the root of the problem - what is it you're actually trying to do via sockets and hand-rolled GETs that you can't do with httpService? -Josh On Thu, Jun 12, 2008 at 9:51 AM, Josh McDonald [EMAIL PROTECTED] wrote: You'll have to use something like Charles to listen to what Flash player is doing behind your back for the policy file to be sure, but if you try and open a socket to somedomain.com:9080, I believe Flash is going to look for somedomain.com:80/crossdomain.xml - Flash doesn't know that the socket you're connecting to is a http server, so it only knows to look in the default location, and it's not going to get your crossdomain file if it's on the server listening on 9080.

[flexcoders] Parsing FLV meta data
Hello all. I am writing a Java library to parse out the metadata of a FLV. It is working OK for a specific .flv, but the problem is the meta data can be rather random of where it appears after the onMetaData header. The FLV usually has a onMetaData and 0-n onTransition headers. Usually there is a Decimal 2 byte (Start of text) followed by a 0 (Null) byte to signify the end. However, sometimes this occurs at the end of eahc 'videodatarate' and 'audiodatarate' data lines (which is still part of the onMetaData tag)...so I am not sure which byte or byte sequence signifies the end of the meta data bytes. Does anyone know? Thanks in advance.

[flexcoders] Problem authenticating Flex to Tomcat with HTTPService
I'm trying to authenticate against a Java-based application server (Tomcat) from my Flex app. I'm unable to set the HTTP Authorization header to pass to the server to authenticate. I'm also not able to read the cookie header that the server sends back after successful authentication. Authenticating to the server with an HTML login page prior to getting to the Flex app is not an option. How have you solved authentication from Flex?

[flexcoders] FileReference woes....
I am rather experienced with the FileReference class but have come across a major problem. Basically, the file uploading just stopped working. It works for me in IE (though I still receive the Error 203 File I/O Error which on the server is a 403 'not authenticated). It does not work at all in Firefox for me (same error). So it is clear Tomcat is not receiving the jsessionID header (which I validated with a packet sniffer). IE is receiving it which is why that works though I'm confused as to why I get the error if the upload took. I am using Tomcat to handle my uploads. Basically, we use a JSP for the user to login (which adds the jsessionID header) and then redirect the user to Flex app (.html and .swf) upon valid login. From there, any upload should (and did) pass that header. But that stopped working and now the errors. Using a packet sniffer, I see the jsessionID is not getting included in the FF POST request. I have seen blogs to tack it on the parameter request but that will not work for me (it has to be a header). This had worked in the past so I am not sure what went wrong. I was on the prerelease version of FB3 (pointing to 2.0.1 hotfix 3)...so i thought it might be my Flash player. I reinstalled the Flash Players for IE and FF from the main Adobe site and no luck. I tried building the swf from FlexBuilder 2...no dice. Really at a loss here. Any thoughts from anyone? Cheers, Kevin
[flexcoders] Re: FileReference woes....
Jon, thanks for your help! We ended up just removing authentication for the upload directory so the upload would work. It's an internal app so that will work for now. The jessionid trick (append to UrlReqest.url) does work, but only if I catch the IOError. That error still gets thrown for me. Not sure if I want to catch that as a solution so I'm going to test more but I am out of options. The bug mentioned below is 'https' which I am not on. --- In flexcoders@yahoogroups.com, Jon Bradley [EMAIL PROTECTED] wrote: On Feb 22, 2008, at 12:56 PM, e_baggg wrote: Using a packet sniffer, I see the jsessionID is not getting included in the FF POST request.

Man... what I'd be really interested in knowing is how in the world it worked in the first place. AFAIK, file uploads with session required have always been broken in FF - I don't know of any instance where it worked without passing the session details back to the server. Was there a change in your upload code in JSP to require authentication? I found the error when our server was setup for authentication but the code accepting the file upload ignored the session details.

[flexcoders] DataGrid HeaderRenderer Recreates every click
I have a server-side sort on my DataGrid which means I had to implement my own headerRenderer to handle the click event, sort, and server calls. I am trying to create the asc/desc arrow now but I realized that any click event on the DataGrid instantiates a new Object of the headerRenderer (all of them actually). In other words, my headerRenderer mxml implementation, the creationComplete event gets called any time ANYTHING is clicked in the grid, including a row. This is a problem for many reasons, but the most significant one being that I cannot store the state if the column is ascending/descending based on the user's click. I could store this externally in the model but that is very bad b/c then I'd also have to store which column was clicked and then the other columns have to check if it is itself and remove the arrow if they have one. Does anyone know why the headerRenderer is re-creating an instance of itself every time or faced this issue? Thanks in advance.
[flexcoders] Re: DataGrid HeaderRenderer Recreates every click
Alex- Thanks. The issue is when a user clicks a column header, all the column headers are re-created and now there is no way to know what just happened since any state of that click event is lost. So I guess I am forced to save it outside the headerRenderer. I suppose I can store the column index of what was clicked, then each column when it redraws itself can get that int (if it's not -1), look that value up in the 'columns' array and see if itself is it. If so, then display the appropriate up/down arrow. --- In flexcoders@yahoogroups.com, Alex Harui [EMAIL PROTECTED] wrote: People do some really tricky things in customized DGs like having headers grow and shrink or other rows grow and shrink based on rollover states and selection and what not. Right now the DG aggressively redraws to make sure we don't make assumptions about what can change. In theory, your custom header renderers should derive their state from some description of the sort. That's a good model/view design and the cost should be insignificant.

[flexcoders] Re: Need help seaching and comparing in an ArrayCollection
That is exactly what you need to do. Create a for loop and get a handle on each object in the loop. Then, set up a method that returns a Boolean if it needs to be flagged. This method will check the dates. if true, then inside your For loop, flag the data object. Note: You can do the conditionals inside the for loop, it's just better for readability to extract that logic out to another method within the same class. --- In flexcoders@yahoogroups.com, Mark [EMAIL PROTECTED] wrote: I'm at a bit of a loss right now how to do something.

[flexcoders] Re: socket question
David,
We are able to have some synchronous behavior to sockets. What we do
is assign a unique ID with each request the client sends, and when the
server is done, it passes that id back.
So to further illustrate your example:
Client sends this:
getServerData id=1 data=yourData/
The server would then send back:
yourData id=1blahblahblah/yourData
done id=1
Then, on your onData() method, you can check all done/ XML, get the
ID, and then use that ID to look up a callback function that you
registered with that ID.
Basically, all of our requests go through a Command which implements
the IResponder class, we register that class to a Singleton which
holds all the callback with the id...and when we see done/, we
check to see if a callback is there and if so it calls it's method.
This ensures that all the data is back we want. Even if your
getServerData request returns multiple socket messages:
getServerData id=1 data=yourData/
yourData id=1blahblahblah/yourData
yourData id=1blahblahblah2/yourData
yourData id=1blahblahblah33/yourData
done id=1
Hope this helps.
-Kevin

Hi all -
I am creating a server interface, one of whose implementations
involves talking over a socket connection. I have a need for
synchronous behavior - I call an API method, say
getServerData(aParam), and I get back the result that I want. Not sure
what a good way to do this with sockets would be since the receive
data event makes them asynchronous in nature - can anyone point me
to a good tutorial, or provide a hint?
Consider a made up example :
class SocketServer implements Server
private var _lastResult:String;
// client calls this method and expects a result passed back
public function getServerData(aParam:String): String {
_socket.addEventListener(ProgressEvent.SOCKET_DATA, onData);
connectToSocket(someHost, somePort);
_lastResult null;
issueCommandViaSocket(aParam);
// sit around until we get data
while (_lastResult == null) ;
return _lastResult;
}
private function onData(e:ProgressEvent):void {
_lastResult= socket.readUTFBytes(socket.bytesAvailable);
}
this works conceptually, except that the wait around part hangs the
app.. if I remove that, then I can get the return value and log it in
the onData method.. so, am I even on the right track here? Is there
some way to have actionscript pause or wait until the desired event
gets fired?
thanks for any thoughts -

[flexcoders] Socket woes - something simple I'm sure
Hello. I have a XMLSocket class that I am able to send/receive data to
no problem.
I switched my implementation to use the flash.net.Socket class and now
I cannot receive data back.
I updated my sendMessage() to the following...this request should
trigger a response from the server but it doesn't...most likely b/c my
request is incorrect. What does the XMLSocket do for me that I am not
doing here? I thought maybe adding the \n to the String would work
but it did not. The sendMessage() method is called in my
connectHandler so I know the socket is connected. There are no errors
in my IO and security handlers.
import flash.net.Socket;
public class MySocket extends Socket
{
...
public function sendMessage(xml : XML) : void
{
try
{
var ss : String = xml.toXMLString();
//ss = credentials user=me password=pass/
this.writeUTF(ss);
this.flush();
trace(Send--: + ss);
} catch (error : IOError){
trace(Error: + error.message);
}
}

## Try adding a null byte before flushing the flash.net.Socket.
Ted-
Thanks for your response but I am still unable to get it working.
Partly b/c I can't find any help on how to add a null byte. I would
think this (or '\0') would accomplish it but it does not. Sorry,
couldn't find any help online.
//this is a connected flash.net.Socket
this.writeUTFBytes(xml.toXMLString() + null);
this.flush();

That should work seamlessly.
Also on the receiving side, you will need to read bytesAvailable into a

Thanks for your reply, I don't know why this is turning into such an issue for me, but according to the XMLSocket API, all it does is send a XML message followed by a zero byte...so why doesn't this work for me?

[flexcoders] Unable to pull up API in FlexBuilder with Ctrl + Spacebar
This has to be the most frustrating thing I've come across in a long time (more frustrating then when my computer got hosed trying to debug Flex 1.5 apps accidentally with the Flash 8.5 beta plugin). Anyway, I am no longer able to pull up the dynamic menu of class names and variable attributes when typing code in FlexBuilder and hitting Ctrl + Space bar. Right now, I have to manually copy and paste full class names to import a class, and ctrl + click around to get variable names. This has dramatically slowed my performance. Not to mention having to go to the docs to see the available functions. :-( If I type var s : S .. then the menu pops up and as I keep typing String it narrows down to String...but for existing lines of code like this: var readyTimer:Timer = new Timer(100, 0); readyTimer.addEventListener(TimerEvent.TIMER, timerHandler); If I put the cursor after the readyTimer. and hit Ctrl + Spacebar..I get nothing. I've tried all of the following to no luck: 1.) Running Project -- Clean 2.) Restarting my PC 3.) (From the beta days), Removing the Flex Project, then deleting the 'bin', 'html-template', and '.settings' directories and the .project, .flexProperties, and .actionScriptProperties files...then recreating the Flex project. 4.) Uninstalled my Flex Builder, downloaded the latest FB2 from adobe.com, and created the new project pointing to my files. Any ideas? I do not have any Problems (errors) in my Project. This problem exists for my AS files and MXML files. I know for a fact my Ctrl spacebar buttons work too b/c I can Ctrl Save. *sigh* -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

That worked fabulously. Thanks.

Another option would be to write a custom ItemRenderer for the List and

If you set the itemRenderer property of the List to IconRenderer then it

Yes indeed, the only way to use this iconField is embeding an
Image. There is a workaround using a normal image component and loading
dynamically, but you will have to build your own popup window in some
cases ( try setting the image component with a negative y ), otherwise
its not to hard thought, you just have to start from a Canvas and design
the layout of your popup.

Betreff: [flexcoders] How to load an Image dynamically as for

I have an application that has a popup window that users will
popup
very rarely. This popup window has a mx:List with a dozen
different
icons for each row in the List.
For this reason I do not want to embed the images, but rather,
load
them at runtime when the wndow is popped.
I am having trouble displaying the icons because the iconField
and
funtions require an Object of type Class. Using the Loader()
class,
a DisplayObject is returned:
var pictLdr:Loader = new Loader();
var pictURL:String = banana.jpg
var pictURLReq:URLRequest = new URLRequest(pictURL);
pictLdr.load(pictURLReq);
this.addChild(pictLdr);
How do I load a image dynamically and assign it to an icon?
Thanks.

Flex can't access your Spring Beans directly.

[flexcoders] Re: CairngormEvent Antipattern
Andi- Tom was referring to having a hierarchy of FrontControllers. He happens to have a class called CoreController which all of his Flex apps would use. Then, each Flex app will have it's own FrontController that extends CoreController...this way each developer has their own controller. This assumes of course there's 1 developer working on a project. The CoreController would house the common Commands such as Login, Logout, and similar things. If you're in the situation where you have 1 large Flex app that has 1 large controller that all the developers are fighting for...I would suggest that users update the Contoller and check in their empty Command classes right away. Then begin development. That way if it takes them 2 days to implement the logic for an event, they won't have a lot of contacts. Another option is to make one developer the 'owner' of the front controller and have other developers e-mail them the line of code for the command. --- In flexcoders@yahoogroups.com, Andrea Varga [EMAIL PROTECTED] wrote: Tom Chiverton wrote: On Wednesday 30 August 2006 13:14, Andrea Varga wrote: (For example, on a large project, when there are many developers working, all of them has to edit the FrontController to add an event.)

You have to calculate that yourself. Add an event listener for

Andi- Nothing changes with the FrontController and Commands. You would still have 3 separate commands (1 each for add, update, delete). Remember, the generic CairngormEvent classes calls: super(commandName) so the dispatchEvent() for each call would like this: dispatchEvent(new WidgetEvent(WidgetFrontController.ADD_WIDGET, widgetVO)); dispatchEvent(new WidgetEvent(WidgetFrontController.UPDATE_WIDGET, widgetVO)); dispatchEvent(new WidgetEvent(WidgetFrontController.DELETE_WIDGET, widgetVO)); and each Command will apropriately be called just like it was.
