[flexcoders] Picasa Flex API - Build your own frontend for Google Picasa backend.

[lytvynyuk]

I want to show people what I beed dooing from time to time in moment
when I had spare time. I think It can be useful for people who want to
make galleries but not to be care about backend anf for anybody who want
to intergrate their apps with Google Picasa

http://code.google.com/p/picasa-flex-api/


There are couple sample applications illustrating how all that works:

and http://riahut.com/files/portfolio/index.html

Any ideas? Hey, Flex gurus I know you are here! :)

[flexcoders] How to optimise SWC to its minimal size?

[lytvynyuk]

I've created SWC consisting from a single class but class contains a bunch of 
methods and when I built  SWc i found that it is 87Kb. In same time report.xml 
stated that my class is only 3kb, everything else is garbage consisting from 
many Flex frameworks classes used directly or indirectly in my main class.

So question how to build my own SWC without all redundant classes?

What is the reason  to keep all that? As I understand when my SWC will be 
linked in flex Application Flex builder will add only required classes to the 
result SWF ?

You can create simple redirect script that redirects requests from your app to

[flexcoders] Rotation/Zoom effect applied to the Image looks too aliased! How to fight it?

[lytvynyuk]

Is there any library which allow you manipulate images but with better
resulting quality then original effects in Flex?

If you do 5 rotation to an Image it looks really ugly... same with
Zoom and scale.

[flexcoders] How to remove effect applied to image to its original state

[lytvynyuk]

Lets say I applied rotation to an image.
I kept that Image object reference.
Then I want to apply other effect to same image object, but previous
effect already altered image.

So question is how to restore original state of the image?
Reloading not seems to be working, I mean image.load()!!!

[lytvynyuk]

I getting this error, but when I put breakpoint at my server side code
nothing coming through!! When I created little HTML page with file
upload filed to same servlet location - IT WORKS!

I used "Live HTTP headers" to see activity on HTTP requests -
nothing nothing going through, also I used Wireshark - same effect.

So what is going on ? any Ideas?

AS code is extremely simple:

var request:URLRequest = new URLRequest();
request.url = UPLOAD_URL;
fr.upload(request);
fileNameLabel.text = fr.name;

 static public function cloneDictionary(oldDictionary:Dictionary,

 {
 var newDictionary:Dictionary = new Dictionary(weakKeys);
 for(var key:Object in oldDictionary) {
 newDictionary[key] =

[flexcoders] How to manually delete references to objects?

[lytvynyuk]

I saw some examples like that:

// create a new object, and put a reference to it in a:
var a:Object = {foo:"bar"}
// copy the reference to the object into b:
var b:Object = a;
// delete the reference to the object in a:
delete(a);

But it definitely wont even compile.

Is there any techniques to do so?

[flexcoders] Re: Singletone class in Application and Modules !?

[lytvynyuk]

I figured out the case. I, actually, made first instance in another
module not in main App.
Conclusion is: if you make instance in your main app - everything works
fine.
If you did it in one of modules, this and all others will get new
instances. Very easy to see when put trace("BLAH") in the constructor.
PS. do not include your class, which suppose to be singleton in you main
application, and then it will fail.

Is it true if I have singleton class instantiated in main application
and in module, instances will be different?

 }

 public function DataManager() {

 }
 }
 }

in main application:

   private function init():void {
   this.dataManager = DataManager.instance;
   }

in module

   private function init():void {

How typically you detect if Charts are leaking? Coz I having troubles

One more things - 
Is it possible to have any potential problem with constructiuon like:

arayColl.addItem({name:"Name", value:23}); ?

in favor of following piece of code:

var myObj = new MyObj();
myObj.name = "Name";
myObj.value = 23;
arayColl.addItem(myObj); ?

[lytvynyuk]

O, thank you! What about array.length = 0;?

Returning to WeakMethodClosure - in 1 hour of running application 
profiller has 5600 instances of this thing, take 90kb of memory. 
Examinig backreference shhows that many of them is adding events 
listener inside components like charts. Are this valid things or just 
something internal what I shoul ignore?

[flexcoders] Dynamic ColumnSeries leavine a lot of garbage in memory.... example inside

[lytvynyuk]

My gola is to create Column chart with series which can be dynamically
modified (number of series may vary)
I created this piece of code, i works, but pluut memory alot by
ColumnSeries object which are loitering or just hanging.

I spent a lot of time to find a way to destroy them, not
successfuly. Here is the code:

var columnSeriesArr:Array = new Array; // global var

//

var i:Number = 0;

// clean somehow array of series;
var ser:ColumnSeriesEx = columnSeriesArr.pop();
while(ser != null) {
(ser.dataProvider as ArrayCollection).removeAll();
ser.dataProvider = null;
ser.displayName = null;
ser = null; //??
ser = columnSeriesArr.pop();
trace('cleaning')
};

for each (var item:Object in arrayC)
{
columnSeries = new ColumnSeriesEx();
columnSeries.dataProvider = item;
columnSeries.yField = "value";
columnSeries.displayName = item.name;
columnSeries.setStyle("fill",  PublicConstants.FILLS_COLOR[i]);
columnSeriesArr.push(columnSeries);
i++;
}

this.columnchart.series = columnSeriesArr;

//

//Column chart defined somewhere below


Any advises?! Thank you.

[flexcoders] Re: WeakMethodClosure - what is this ?

[lytvynyuk]

Thank you Alex, minimizing in my case doesn't help.

Can you suggest a proper way of cleaning up Array.
For example I have dynamic series for the column chart.
And I create new set of series and assign them this way:

var mySeries:Array = new Array();
/* some loop */
columnSeries = new ColumnSeriesEx();
mySeries.push(columnSeries);
/* loop end */

// trying to clean-up array to free all series was assigned before.
this.columnchart.series.length = 0;

this.columnchart.series = mySeries;

Or may be there is another way of proper cleaning up array to free all
references was there before?

[flexcoders] WeakMethodClosure - what is this ?

[lytvynyuk]

During my research with Flex performance found that instances of
WeakMethodClosure constantly increasing. I do not have knowledge what
is that and how to avoid it. 1859 instances for example can take only
30k of memory... but still

BTW found that Flash player running under Firefox & Opera newer free
memory. Even when profiler shows clear memory dis-allocation.

[flexcoders] Memory allocations problems when intensively using charts and modules

[lytvynyuk]

I having really serious troubles with my application when using
charts. My application collects lots of data in pseudo realtime (poll
for data every 5 sec) and display charts and graphs. Everything works
fine but with time memory allocated by Firefox process getting
enormous and Firefox eventually dying. When I used profiler to see
memory allocation, I noticed that I have megabytes of UTextField
objects allocated, also ChartLabels. Definitely all these object
wasn't GCed properly!

Another problem loading and unloading modules. After each load Firefox
allocates another 4-8M of memory and never comes back, even if I do
unload ! But in same time profiles shows 0 instances of modules which
was loaded. Whats is going on there?

Just to be clear:

I always do destroy event listeners, do not use static classes, always
cleaning up arrays via ramoveAll(); I assign modules instances ans
well as arrays to NULL when they not needed.

What else I need to do?

[flexcoders] Re: Flex Ant Task for F3b3 genereates ALWAYS debug version, how to fix that?

[lytvynyuk]

I see, still I have debug version, which popups exceptions when
something happened.  (BTW, how to distinguish between debug and non
debug, size?)

But another fun started when I deployed everything under Linux (Red
Hat) Application was build and linked using framework_3.0.189825.swz 
under windows, and I works well there. But when I copied same files
under linux right away I got Error #2046. BUT is copied ORIGINAL swz
from Adobe SDK folder.

In trouble shooting guide it sais:

This error indicates that the loaded RSL was not signed properly. In
the case of framework RSLs, the framework's SWZ file that the
application attempted to load at run time was not a properly signed
SWZ file. You must ensure that you deploy an Adobe-signed RSL.

I'm pretty sure I copied original file taken from Flex 3B3
distribution. What is wrong?!

[lytvynyuk]

In that case no point to report bug, everything works for me too.
Problem for me is different actually it is about RSL.

I try to build everytinh with RSL which suppose to decrease size of my
application. WQhich is not happening. AS you see I included RSL into
my flex build task but it doesnt really affect anything, with or without 



it produces same size app, but when I compiled it WITH and run it it
demands presence of framework_3.0.189825.swf.

With ECLIPSE it actually decreases size of application.

What is the syntax of correct usage of RSL in ant?

Modules work only with Flex 2.0.1
RSLs mentioned here only with F3B2!
What kind of version are you running?

Keep in mind you can link SWC anly at compile time, if somebody think
I'm wrong, please correct me. SWFs you may load at run time for sure.
But can you execute code from them - I doubt.

My choice will be modules.

BTW RSL it is a bit different story - RSL servers for share COMMON

[flexcoders] Re: SQLite help Flex 3 Beta 2

[lytvynyuk]

If you are not getting any SQL exceptions, check you OrgId, and actual
IDs in table. Then check what do you have in result variable.

[flexcoders] Re: Flex grid to serve 100K-1mil rows

[lytvynyuk]

Personally i think it very bad idea, can you imagine sort/search 1M
records at client, how fast it will be ? What if you decided to do
full text search by pattern? your client will die! Can you image how
much memory it will consume at client side?

best way to do is - smart server querying, pagination and dynamic load.

Thank you Troy, for your suggestions.

I cannot understand one thing, using SimpleXMLDecoder i got Object
from XML BUT I cannot make this ObjectProxy cast to my Album Object.
What is the condition to cast object fields are same, I cant
understand how does it works :(

[flexcoders] Re: How to converst an XML to AS Object ?

[lytvynyuk]

Thank you I kinda knew about that way ;)
but if my object contains30 fields and also has a bunch of another
objects, this procedure will be painful  ;)

What about this way:

public function result(event:ResultEvent):void {
var xmlS:XML = XML(event.result);
var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(true);   
var xdoc : XMLDocument =  new XMLDocument();
xdoc.ignoreWhite = true;
xdoc.parseXML(xmlS.toXMLString());   
var ob:Object = decoder.decodeXML(XMLNode(xdoc.firstChild));
var feed:Album= Album(ob); // Exception here
}

But this doesn't work for me too ;)

[flexcoders] How to converst an XML to AS Object ?

[lytvynyuk]

Situation I have XML like that 









using HTTPService I'm getting this XML.

I have AS Class:

public class Album {
public var name:String;
public var images:ArrayCollection;
}

straight cast like:


var album:Album = Album (event.result);


doesn't work

Is any suggestion around this, what I do wrong, may be there are some
other way to do that

Thank you.
