Subject: [flexcoders] Memory Leak in DataServices based App ??
Hi All,
I have very basic application which uses DataSerives over RTMP channel
to populate dataGrid , I have not used any user defined component.
This application has got LOAD data and Remove data Button just to simulate the
actual application
What happens , when I click on LOAD data , It loads the data from
server(JBOSS) then I Remove all the data and force the GC to run
If I continuously keep loading and removing the data , memory goes up every
time and after some times It reaches to threshold and finally crashes the
Browser.
In actual application as soon as user logs in a dedicated DS destination is
created..
private function createDestination(destName:String):void{
var remoteServi! ce:RemoteObject = new
RemoteObject(DestinationManager);
remoteService.addEventListener(ResultEvent.RESULT,
resultHandler,false,0,true);
var operation:AbstractOperation =
remoteService.getOperation(createDestination);
operation.send(destName);
var cs:ChannelSet = new ChannelSet();
var rtmpChannel:RTMPChannel = ServerConfig.getChannel(my-rtmp) as
RTMPChannel;
cs.addChannel(rtmpChannel);
! ; tradeService = new DataService() ;
! ; nbsp;tradeService.destination=destName;
tradeService.channelSet = cs;
}
Now when user hits on Load data button to load the trade data ...
public function loadData():void
{
var remoteService:RemoteObject = new RemoteObject(filterRemoteVO);
var operation:AbstractOperation =
remoteService.getOperation(loadData);
tradeService.fill(tradeCollection);
operation.send(rowData.t! ext ,GUIID);
tradeList.dataProvider = tradeCollection;
}
Remove Data hit I clean all the resource and released collection :-
public function removeAll():void{
if(tradeList.dataProvider){
tradeCollection.source = new Array();
tradeList.dataProvider.source = new Array();
tradeList.dataProvider = null;
}
tradeService.release();
nb! sp; ; tradeService.releaseCollection(tradeCollection);
tradeService.channelSet.disconnectAll();
tradeService.disconnect();
tradeService.logout();
System.gc();
}
Except these 3 function I don't have any code which could cause memory leak.
I m using
* LCDS 2.5
* Flex 3.0
* JBoss4.2
Please see the mxml file below , If possible please have a look at it , I
might not be using dataSerice API correctly.
I have been trying to solve this leak for last two week , I really need help
from you guys.
My client has already evaluating other contemporary technology because of this
memory issue.
I have al! so created scalled down war file which can be deployed on any java
application server.Just provide your emial Id , Iwill send that to you.
Any help will greatly be appreciated

[flexcoders] Re: Memory Leak in DataServices based App ??
I have gone throw your tutorial on you blog and I profiled my with. I
could see so many loitering object hanging around , I evaluted them
based upon the method suggetsed on your blog.
Potential Loitering Obejct which I could see is -
* Objects
* Strings
On drill down , I found tons of obejct of following :-
AbstradeDataServies
NetConnetions
ManagedObjectPeoxy- It is refering to DataGridItemRenderer
Worst part is they keep increasing everytime when I load the data and
remove it.
I have removed all my custom code and now app is very bare bone.Lately I
though I could seek help from flexCoders.

[flexcoders] Flex Library and and MXML component
I have an MXML Component Canvas that I want to put into a Flex Library SWC. I created a Flex Library Project with /src and /bin I added the /images folder with the image in it that the Component Canvas uses to /src. I added the mxml source file for the Component to the /src The /bin gets the MyLibProject.swc but the mxml component isn't inside. I am sure I am missing a step but can't find what it is. I want to use this swc in several projects as a component on other screens. -- View this message in context: http://www.nabble.com/Flex-Library-and-and-MXML-component-tp24233741p24233741.html Sent from the FlexCoders mailing list archive at Nabble.com.

[flexcoders] Is there a good log application?
Hi, I was wondering if anyone can point me to an easy to use logging application? Looks like Flex used to have one called MiniDebug but it's deprecated. My problem is that my testers have many difficulties configuring the flash debugger and the flashlog.txt (permissions on vista and other issues), I think something that uses LocalConnection or some JavaScript Target could do the job. Note - I need something that is supported on multiple environments not just firebug on firefox. Tnx Guy

[flexcoders] Paging collections with more than 1 filter
Hi, I have an ArrayCollection that I use as a dataProvider for a DataGrid. To enable paging, I filter the collection. The problem is that I have another filter function for that collection where a user can retrieve rows via string search. This works fine except when the search returns multiple pages because on the first page click, the original (unfiltered) collection is used instead of the collection that I just filtered. I suppose that I could create a copied collection on string search and then set a flag to let my other filter function know which collection to use. However, I was hoping there's a more elegant solution. Anybody know one? Thanks for any helpful tips...
[flexcoders] Re: Is there a good log application?
That doesn't help unfortunately.

RE: [flexcoders] Re: Memory Leak in DataServices based App ??
Make sure your scenario should be using loitering objects. As I explain in the
blog article, many scenarios will get false results using loitering objects.
If you look at the allocation traces for the objects in question, you can then
consider how those created objects get released so they can be garbage
collected.

[flexcoders] How do I create in ActionScript what MXML lets me do?
Data can be found at http://www.silenttrace.com/deviceData.xml
Question one - How can I create my list, onList in pure actionscript vice
mxml? The reason I want to do this is because I get a null exception
otherwise. I imagine its because I am instantiating the itemrenderer before I
have any data in my arraycollection since a http service call needs to get the
data. So I thought if I wait till line 35 and then instantiate the list in
pure actionscript I am golden. Can someone let me know if that is possible or
how I could achieve this? Things like setting itemChangeEffect and such seem
to be only in mxml.
Question two ignore the itemRenderer of onList and you will see that I get an
error ever time I select the zero Item in the list on the left and click the
addToOffBtn.
