[flexcoders] Does LCDS support replication of runtime created Destination ?
Hi All , I have been working on LCDS clustering and I could successfully got static destination clustering working .. But I need to Clustering/Replication for runtime created Destination. Does LCDS support it ? Regards, Dharmendra
[flexcoders] DataService Destination Clustering is not working
Hi All ,
We are trying to get clustering configured for our application so that
DataService's Destination keep serving the cleint in case of any server
failure . We are using F5 hardware load balancer.
We have set up a default-cluster, using tcp and while creating DataService
Destination we are setting cluster ID as follows
1)
.
DataNetworkSettings ns = new DataNetworkSettings();
ns.setPagingEnabled("false");
ns.setClusterId("default-cluster")
2) service-config.xml
3) jgroup-tcp.xml - First
3) jgroup-tcp.xml - Seond
I am using Jboss4.2.2 GA and LCDS2.6.1 and we have licensed version of LCDS
I am getting following message on JBoss console : -
04:26:15,296 INFO [STDOUT] [Flex]Cluster node from address 114.19.8.161:7800
joined the cluster for default-cluster

Am I missing anything ?
During the testing when I bring down one of the jboss server, It immediately
throws Destination does not exist error
I will appreciate any help on this .

[flexcoders] Does it required to have Licenced Version of LCDS for Clustering
Hi, I am bit confused on LCDS products. I have downloaded trial version and trying to replicate DataService's Destination. Does it required to buy licensed veresion of LCDS to DataServive Destination replication ? My req is If serverA is down then user should immedialtely get connected to serverB with the same state as It was on serverA. Regards, Dharmendra

Hi Alex,

being referrenced from referring to remoteObject.send() method and
few are referencing to fill method of Data Service .
I am clueless as what is wrong with my code.what is the best way to

I can also see tons of string objects in loitering objects pane,
don't know where are they coming from.. allocation trace says
readObject method is holding references to these strings

[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] 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 remoteService: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() ;
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.text ,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();
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 also 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

Dam

[flexcoders] Need suggestion on design
Hi There, I need some thoughts or ideas in designing loading status functionality in flex app. pls see the req below : - Requirement : Showing loading status in DataService based DG and turn it off when loading is done. DataService's fill method is fetching data from Jboss deployed app. When user click on LOAD button , request goes to Java app which in turn submit request to TIBCO EMS server. As soon as result returns from TIBCO a listener get notified where I push returned data to Flex. Call to TIBCO EMS is asynchronous meaning it does not return the data immediately. My req is to show loading status somewhere in app when data load is in progress. Which component of LCDS would serve this purpose ?. Please suggest me some design approach. Regards, Dharmendra
[flexcoders] Re: DataGrid not releasing memory on removeAll()
Hi Adrian Williams
Thanks for the reply.
I have tried your trick but I could not get it working as expected. Here
is the code which I tried in my custom dataGrid:_
arrayCollection.revmoveAll();
for(var key:String in freeItemRenderersTable){
delete freeItemRenderersTable[key];
}
dataProvider = null;
freeItemRenderersTable is protected member of DG which keep all
itemrenderes.
How did your write custom script to release memory ? Please share the
approach which u have followed.

[flexcoders] Re: DataGrid not releasing memory on removeAll()
Hi All,
Thanks for the response.
1) I agree with the fact - that memory is not necessarily released just
after you remove the items from datagrid.
Now my question is how long I have to wait for GC to run and If they
are eligible for GC then memory should be coming down after I issue
Sytem.gc().
Why Memory usage is not coming down even after Force GC ???
1) I do not have any event listerner attached to dataGrid or
ArrayCollection, In fact, In my sample App , I just crated a data Grid
with data provider and thats it.
I suspect , dataGrid does not release its itemerenderer even after
removing all item
After digging the DG code I found following .
Why FreeItemRenderersTable is Strongly Referenced ??
public function DataGridBase()
{
super();
listType = "vertical";
defaultRowCount = 7;// default number of rows is 7
columnMap = {};
freeItemRenderersTable = new Dictionary(false);
}
Is this the only reason for itemrenderes not being eligible for GC ??
Please throw some light on it

Dharmendra

[flexcoders] DataGrid not releasing memory on removeAll()
Hi All, My DataGrid based application running into a Memory issue.The issue is dataGrid does not release the memory even after emptying it. Initially I thought Its my code which is causing the issue, but later I crated a sample application with just a dataGrid and a ArraCollection (no eventListener) and found the same issue. Memory should come down at least some MB when I remove all item from data provider. Memory usage with 10k row - 220 MB Memory usage after removing all item - STILL 220 MB Is this the standard behavior of datGird or do i need to apply some workaround to get rid of this ?

[flexcoders] Re: Need Alternative for enterFrame event (Causing Memory leak )
Hi Mark,
Sorry for late reply.
I have tried the approch suggested by you but it seems that AS3 does not
support it.I might be not be correct but this but this is what I experienced.
I tried both SetVariable and flashVar ,but none these appears to be working.
I have to find out other ways to get of my issue.
Thanks a ton for your help.

Hi Manish, Thanks for the suggestion. I wish , I could use java script to set the Focus but I do not have luxury of Java Script as My application is running as ActiveX control inside dot net based application. Once the callback broken , communication from Ashokwave lib to swf is not possible. This is really a serious issue, I need some work around to fix it as I could not wait till the adobe fix it.

[flexcoders] Re: Need Alternative for enterFrame event (Causing Memory leak )
Hi Alex, I think , I failed to communicate the real issue. Let me try to explain it The issue is with callBack ,what is happening is as soon you hide Flex application by opening another application(any app) and then again you come back to your flex app , call back does not work , they are broken.I found following related jira for this. http://bugs.adobe.com/jira/browse/FP-143 To solve this issue , I am re-registering all callBacks on ENTER_FRAME event and issue appears to be solved but this is leading to memory leak. Neither Activate nor FocusEvent.FOCUS_IN does serve my purpose , both required a mouse Clk before they dispached. Workaroud for any of the above will solve my problem. I am wondering If there is any event which gets fired when I swich back to the flex app again. My application is hosted as ActiveX control and I m calling callback from Dot Net application.

[flexcoders] Need Alternative for enterFrame event (Causing Memory leak )
Hi, I landed up myself in to memory leak and the reason of this leak is enterFrame event. I am re-registering ExterfaceInterface.callBack methods on this event to solve a problem ( callback connection broken on lost focus). memory consumption keeps increasing even when app is idle.. I need a event which gets fired when user switch to my app ,in this event I will re-register call backs to solve broken callBack connection issue. these callback are getting called from Dot Net application. Please , suggest some alternative for EnterFrame event which gets fired on set focus event. Regards, Dharmendra

[flexcoders] How release Memory consumed by DataService
Hello All, dataService.release(); dataService.dissconnect() dataService.logout(); I am using above set of codes to release resources consumed by Data Service. but I was surprised to see that even after running above code memory consumption is not coming down. During profiling I found lot of loitering obeject named ManagedObject, ProxyObject , AsynchToken etc .. I belive they are all created by DataService , i am wondering why they are not gettig destroyed when dataService itself is disconnected. Please suggest me the ways to release all resources consumend by DataService I m using LCDS 2.6 with RTMP channel. Regards, Dharmendra
[flexcoders] Destroy DataDestination when user Disconnects ?
Hi FlexCoders,
In my application a separate DataDestination gets created when user logs
in.
I want(struggling) to destroy the destination associated with the particular
user.
For this I have created FlexSesioListner and as soon as DataDestination gets
created I immediately put it in FlexSession.
FlexContext.getFlexSession().setAttribute("destID" desitID);
SessionDestroy() method get called when user disconnect from app due to any
reason
The issue is SessionDestroy() ,flexsession.get( "destID") retuning null ???
while debugigng i found that FlexContext.getFlexSession() returns
HttpFlexSession ie destID is getting stored in HttpFlexSession
where as in SessionDestroy(FLexSession session) session is of type
RTMPFlexSession hence I am getting null here.
my question is how to put data in RTMPFlexSession so that I can be made
available in sesssionDestroy() method when RTMP client disconnect.
Just want to destroy the DataDestination when user gets disconnected from RTMP
channel based Flex App
Regards,
Dharmendra

[flexcoders] session.getAttribute("somekey") returning NULL in SessionDestroyed
Hi all,
session.getAttribute("somekey") is returning null in
SessionDestroyed() method of flex listener.
Below are the steps I am following
1) I am adding flexLister in contextInitialized method of ServletContextListener
FlexSession.addSessionCreateListener(myListener)
2) In sessionCreate method
sessionCreated(FlexSession session) {
session.addSessionDestroyListener(this)
}
3) some where in applicaion I am putting a key vlaue pair in session like this
FlexContext.getSession().setAttribute("somekey" , someVlue) ;
The issue is when I try to retreive vale from session
her is how I m retreiving value
sessionDestroyed(FlexSession session) {
session.getAttribute("somekey"); this return null WHY ?
}
This is always returning me null
Pls note that I am RTMP channel and version of LCDS is 2.6
I also tried RTMPFlexSession
RTMPFlexSession.addSessionCreateListener(myListener)
but no luck , still got null
Am I doing anything wrong ?
Thanks ,
Dharmendra

Actually , I have two context Menu Item 1) highlight 2)un-highlight they highlight/un-highlight selected row on click event. I found some resource on google ,all of them changing bg color in drawRowBackground(), but in my case I cant use it as I have to execute this logic on context item click. Pleas suggest some ideas. Second requirement is ,when user sort the grid after highlighting row , color of all highlighted row should remain same irresevtive of their new position. Thanks, Dharmendra

[flexcoders] Enable/Disable Context Menu Based on selected row of DG
Hi Everybody, I need to enable/Disable Context Menu Item based the selected row of the DG.ie I would perform some logic based on current selected row to decide enabling/Disabling of context menu item. Classical example of this is Timesheet application. If a manager click on any of the entry which was already approved , he should NOT be getting approve option enabled. I found some workaound to get this functionality workinng but they are all browser based.They do not apply in my case as my application is running on Flash Player.
[flexcoders] Context menu is not working for Flash Player 10
Hi, My Application is working fine with Flash Player9 but with FP10,it's somewhat broken.I am calling some external method throw ExternalInterFace on Context Menu Select event.None of the method is getting called with FP 10 ie call is not being made. Everything is working fine in FP9 have anybody encountered this issue ? what would be the possible workaround for it ?

[flexcoders] Re: DataGrid: How to Prevent Extra Space Allocation to Last Colum
It swapped the order of the columns? yes , Sometimes blank column swpped with other column.It should not happen 1) Is there is a way to prevent this swapping ? 2) Is it possible to get rid of extra space at all without adding blank column ? As per my understing the purpose of this blank column is to absorb extra space and that is why you want it to be resizable = true.

[flexcoders] DataGrid: How to Prevent Extra Space Allocation to Last Colum
Hi All, Please help me to get rid of extra space being allocated to the last column of DataGrid. Where does this extra come from ? whatever column I resize should actually be resized.Why does one column resize led to last column resize ? I have set horizontal policy to auto and resizable = true for all column.Also I cant make resizable = false for last column as It is not acceptable to my client Any help would be appreciated.
[flexcoders] Last Column is getting unnecessary space on column resize ?
Hi All, I have a resizable dataGrid with horizontalScrollPolicy = "auto " , when I resize any column , width of last column is being increased ? If I am not resizing it ( last column) ,why is it increasing its width ? I dived in to dataGrid code and found a method calculateColumnSizes (), this method has got code which assign unnecessary space to the last column. Since this is private method ,I cant ovrride it . Also , when i try to minimize its width ,it required more than 2 attempt to acheive it ..why It is so ? Last colun resizing behavior should be similier to the rest of the column ? Is anybosy has ever faced these issue ? Does anybody know the solution ? Regards, Dharmendra
[flexcoders] GENERIC compareFucntion without hardcoding of dataField ?
Hi All,
My flex2 DataGrid has got at least 50 columns of type Date.I
also have list which opens when use select a context menu item ,in this
list user can select any no of columns on which he wants multiple
sorting to be happen.
Lets say user has selected 5 Columns for multi sorting,I create 5
sortField with compareFunction in loop as follows
var sortFieldArray:Array = new Array();
for(var dataField in selectedColumnArray){
var field:SortField = new SortField(dataField );
field.compareFunction = function(itemA:Object,itemB:Object):int{
var dateA:Date =itemA[dataField ] ;
var dateB:Date =itemB[dataField ] ;
.
}
sortFieldArray.push(field);
}
Problem which I have been facing is ,local var dataField is always
referring to the last value of selectedColumnArray hence sorting is
happening based on last column only.
I dont want to create separate compareFunction for each column , simply
because at compilation time I dont know about the no of column which
user can choose to participate in multipleSorting.And I dont want to
create 50 compareFunction with hardcoded dataField name
Is it possible to create GENERIC compareFucntion which can take
dataField without hard coding ?
Please throw some light on this it?

Dharmendra chauhan

[flexcoders] Re: How to increase datagrid Last Column WIDTH
Thanks Jeffry for your reply.
Well,we can chagne width of datagrid on column strech even.I am
iterating all coloumn and assigning sum of these colums's width to
datagrid.
This works fine in case of all column except the last one.It does not
allow me to increase width of last column.However I can decrease it.
While debugging I found that In case of last column Strech,MouseUp
Event does not get triggred because Mouse Moves out of grid area for
strechng last column. I could not figure out how to make this event
triggred.
I am attaching code here,Please have a look if anoyne of you get
time.
MMXL Code:

[flexcoders] Is It possible to dynamically resize datagrid's Width
Hi All, I have designed a custom data which allows user to add column dynamically.It allows user to resize Column.the functionality which I am looking for is that if I hold mouse on the last column and take it to the right to increase column's width then datagrid should increase its own width to accommodate new width of the column.ie datagrid should expand its width in the right to accommodate/respect width of the column.

[flexcoders] Can we freeze(Fix) Any Column / Row in DataGrid
Hi All, Is it possible to freeze any Column and Row in DataGrid while keeping rest of the Row/Column moving.i e ,If my FG has got four column named A,B,C,D ,E..Z.I want to freeze or fixed column B that means I scroll to right of the grid , B column should always be visible. In case of Row, If I select 10 th row,row from 1-10 should get breezed(fixed) irrespective vertical scroll bar movement. Please point me appropriate direction. Regards, Dharmendra Chouhan
[flexcoders] Advanced Formatting
Hi All, This time I am struggling with formatting as I am migrating Dot Net application to flex.Standard flex library does not support advanced formatting. Here is type of formatting which I want to implement in Flex 1) 0 (Zero placeholder): If the value being formatted has a digit in the position where the '0' appears in the format string, then that digit is copied to the result string; otherwise, a '0' appears in the result string. The position of the leftmost '0' before the decimal point and the rightmost '0' after the decimal point determines the range of digits that are always present in the result string. The "00" specifier causes the value to be rounded to the nearest digit preceding the decimal, where rounding away from zero is always used. For example, formatting 34.5 with "00" would result in the value 35. 2) #(Digit placeholder): If the value being formatted has a digit in the position where the '#' appears in the format string, then that digit is copied to the result string. Otherwise, nothing is stored in that position in the result string. Note that this specifier never displays the '0' character if it is not a significant digit, even if '0' is the only digit in the string. It will display the '0' character if it is a significant digit in the number being displayed. The "##" format string causes the value to be rounded to the nearest digit preceding the decimal, where rounding away from zero is always used. For example, formatting 34.5 with "##" would result in the value 35. Please suggest me ways to provide advanced formatting in flex. Any help would be highly appreciated Regards, Dharmendra

Hi All, I have designed a custom dataGrid which allows user to select column which he wants to be visiable.Here is the issue which I have been facing: When user select two column to be visiable, Lets assumeCol1.with = 25 , Col2.with = 20 , Expected Result: It should occupy 25+20 pixel space and adjust datagrid size accordingly. Actual Result: Col1 is occupying correct space but col2 occupies all rest of the space available on the right hand side i.e. col2 is to occupying more space than it is suppose to be. I want col2 to occupy only 20 pixel space. datagird height and width both are 100 % Any help would be highly appreciated. Regards, Dharmendra Chouhan
[flexcoders] Re: Data Grid Issue
Hi Sanjay,
Thanks lot for you reply. Please share that piece of code where in
you are storing the index of selected row at the respective index of
array.
How did you u get the row which need to be selected, are you also
calling a method on mouseOver function.
I desperately need this functionality in my project. Please share
your sample app if possible or have a look in my code below, please
point me to the location where I need to focus.

Dharmendra

[flexcoders] Data Grid Issue
Hello,
I have designed a custom dataGird which allows user to select
multiple row without shift key. that meas user just need to right
click the mouse and drag it over the grid. For this I have
override mouseOverHandler Function in my dataGrid.
override protected function mouseOverHandler(event:MouseEvent):void
{
var selectedArr:Array = new Array();
if(isMouseDown){
try{
selectedArr = dg.selectedIndices;
selectedArr.push(mOver.target.listData.rowIndex);
dg.selectedIndices = selectedArr;
}catch(e:Error){
}
}
}
Issue wich I have been facing is 'mOver.target.listData.rowIndex'
does not consistently return rowIndex ,whenever I move mouse with
fast pace
1 ) it throws an error " Property listData not found on
mx.controls.listClasses.ListBaseContentHolder
and there is no default value" .
2) Some dataGrid does not dispatch mouseOver as a result
mouseUpHandler does get called.
I hope you are convinced with observation.Please let me know you
have any workAound for the above issue.

Dharmendra
[flexcoders] Multiple selection in dataGrid by dragging Mouse with left mouse key
Is it possible to select multiple rows in data grid by just dragging mouse over It. I know this can we achieved with combination of sift key and mouse. This need has arisen because we are migrating .DOT Net data grid with flex data grid and user want to have same ease of multiple selection. Initially I was confused with dragMultipleSelection propery of datagird but later I realized that it is for dragging rows and not for selection. Please let me know whether it is possible in flex or not and if it is possible then please provide me some pointers.
[flexcoders] DataGrid MultipleSelectio with mouse only
I want to provide functionality where in user can select multiple
rows in dg by holding left mouse key and dragging over the dg.
I have also designed a sample app for this but Only issue with
approach is that It(mOver.target.listData.rowIndex) does not
consistently return rowIndex ,sometimes It throws error `Property
listData not found on mx.controls.listClasses.ListBaseContentHolder
and there is no default value" as a result of it ,few row left
unselected.
This error occurs only when user tries to select rows with fast
mouser movement.
