Hi Nithya,
Just checked and found that everything seems to be working fine. I am not sure, why it is not working on your machine.
Run the attached example on your machine and see if it is working. I made slight changes like, removed cellRenderer="Thumbnail" from TileList attributes because I don't have Thumbnail renderer.
But if it runs there then your code might have some problems...

Re: [flexcoders] Http Service -- urgent
From the faq: 5. Guidelines to effective question-asking Include a useful subject; this will help people find their own questions and answers later. Explain what you are trying to accomplish. Explain the error (include compilation errors or a description of the runtime behavior). Be prepared to break your problem down into a simpler scenario in case someone wants to try to debug the code themselves. Remember, private web services are inaccessible; you may need to create some dummy data to emulate problems. Phrases to avoid: URGENT (we all have deadlines, no one is intentionally delaying a response to you) Please send code (this is very frustrating to read as it implies you aren't interested in learning anything on your own. Where code is appropriate you can expect someone to provide it, but in many cases you will learn more by doing it on your own with appropriate guidance. It may be that you're on a deadline and just want to finish, but many of those who respond regularly would prefer to teach you to fish so that you can answer your own questions next time and even help out others).

[flexcoders] Web browser crashing on remote method call
I've searched previous postings and I cannot find the solution to
this problem for the life of me.
I am making a remote method call which retrieves an array of
JavaObjects. Within each JavaObject, i have 5 string attributes, and
1 attribute that is an array of custom Java Objects. I have narrowed
down the problem down to this array.
Whenever I preview my mxml object, the web browser hangs and never
gets past the initialize screen.
I've included my mxml file below. I saw a posting that all the Java
objects need to have empty construtors. I did that but the browser
still hangs. I created AS classes and included the static var for
Object.registerClass, but that did not work for me either. If I
comment out my array of custom objects in my MainObject(and the
getter and setters), the datagrid loads fine. Any ideas?
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml;
xmlns=* pageTitle=Dispatcher initialize=startApp()
mx:Script
![CDATA[
import com.myAsClasses.*;
function startApp()
{
myobj.findJobs(null); //i can see in a java println data is returned
}
]]
/mx:Script
mx:RemoteObject source=com.RemoteServiceImpl type=stateless-
class id=myobj
mx:method name=findJobs /

width=100% height=375
mx:columns
mx:Array
mx:DataGridColumn columnName=myattr headerText=Attr /
/mx:Array
/mx:columns
/mx:DataGrid
/mx:Application
My findJobs method return an array...for example MainObject[].
My MainObject has the 5 String attributes and 1 attribute
SiblingObject[]. In my datagrid I am not even referencing any of
these attributes so it is failing trying to serialize them.
My MainObject class in Java has:
private SiblingObject[] = siblingObjects;
My MainObject class is AS has:
var siblingObjects: Array = new Array();
I created my AS classes (using FlexPojo2AS--
http://www.meagle.com/FlexPojo2AS/FlexPojo2AS.html), but that did
not solve my problem. I know the AS classes are OK because I've used
them before, just never with object graphs before. I'm sorry if this
is a beat topic, but I haven't seen any posting on the client swf
file hanging the browser.
Thanks.

RE: [flexcoders] Web browser crashing on remote method call
It sounds like you might be in an infinite loop somewhere on the client... a common way to get into such a loop is when processing object graphs with circular references. From your MXML code listing below (i.e. it shows direct binding of the RO result as a data provider) I don't see that you're doing any recursive processing of the result so I'd propose that you've discovered a bug with DataGrid when bound to object graphs that have circular references. How, you might ask, would you have a circular reference in an object graph from a RemoteObject result? Without seeing any of the code for the object graph I can only guess that somewhere in your sibling instances you have a pointer to a parent main object (or perhaps some circular dependency between sibs, whatever). When serializing objects over AMF the client and server will attempt to restore references between complex objects, for example, Just say we have two objects, A and B where B has a reference back to its parent A: A - B - A RemoteObject will serialize the A property of B as a reference to the instance A, rather than reserialize A again. This allows the client and server to support circularly referenced object graphs and avoids infinite recursion on serialization/deserialization. To prove that this is indeed happening you can turn on Debug level logging for the RemoteObject gateway in the /WEB-INF/flex/gateway.config.xml file, restart the flex server, and then watch the server console for AMF traffic, you should be able to see the by-reference serializaiton entries in the log.

[flexcoders] RadioButton in a DataGrid
Flexcoders,
I am trying to put a single radio button on each row of a datagrid so
that I can use it as a selection for the next piece of a workflow. So far I
have it displaying correctly by using a cellRenderer that is below. The
problem is that I can select more then one of the radio buttons at a time so
they are not mutually exclusive. Has anybody done this sort of thing
before? Is there a better way to do this or am I just missing some piece of
magic to make it work?
I did also try to put a RadioButtonGroup on the DataGrid but it seems to get
ignored in the cellRenderer. My guess is that there is a namespacing issue.
Thanks,
-Kent

[flexcoders] Fade effect just showing end state ?
Hi,
I've coded a couple of AS functions which I intended to use to fade
the component they're within, in and out.
I've listed the functions below...
However, when I actually run the code, there seems to be no actual
fade effect taking place - the object just moves directly to Alpha
30 on fadeOutEffect and back to 100 on fadeInEffect. There's no
actual gradual fading at all.
I guess I'm doing something wrong! Any ideas ?!
Thanks,
Jamie.
function fadeOutEffect(){
var fadeOut = new mx.effects.Fade(this);
fadeOut.alphaFrom = 100;
fadeOut.alphaTo = 30;
//fadeOut.suspendBackgroundProcessing = true;
fadeOut.duration = 1000;
fadeOut.playEffect();
}
function fadeInEffect(){
var fadeIn = new mx.effects.Fade(this);
fadeIn.alphaFrom = 30;
fadeIn.alphaTo = 100;
//fadeOut.suspendBackgroundProcessing = true;
fadeIn.duration = 1000;
fadeIn.playEffect();

I don't find much comfort in the liveDocs explanation at: http://livedocs.macromedia.com/flex/15/asdocs_en/mx/controls/ treeclasses/TreeDataProvider.html and Developing Flex Applications and the book don't really give many pointers either.

[flexcoders] Re: Web browser crashing on remote method call
Pete-
Thanks for your help...I've finally identified the problem (but
still not the solution). Although I did have a reference of my
siblingPojo back to my MainPojo, commenting out that code did not
solve the problem. However, my SiblingObject has an attribute that
is part of a class with static variables. So to give you an example,
my SiblingPojo has an attribute like this:
private Status status = null;
When I construct my data objects in the back-end, I set this
variable using it's own static data:
siblingPojo.setStatus(Status.CONFIRMED);
Here's the Java code of the class that the serialization is hanging
up on. This is a pretty standard j2ee design pattern. You'll see
that I only have a private constructor. This is what ensures that
the variable data will be constant throughout the app. If I were to
add a public constructor, the class would not compile (since my
variable 'type' could technically never get instantiated)...I'm
guessing the serialzation is hanging b/c there is no public empty
constructor?
have you ever come across a situation like this before?
Thanks again for your help.
public class Status{
private final String type;
private Status(String type) {
this.type = type;

[flexcoders] Re: Flash V2 Components and Flex Compatibility
You'll probably have to provide more details about how the List is being used, but in general, we don't promise that Flash V2 modules drop into Flex. One of the main issues is that Flex is entirely dynamic. It instantiates all of the components on-the-fly. In Flash one can easily place components on the stage or in other symbols. If you did that, it probably won't run in Flex as that is non-dynamic and the instantiation sequence in that case is not supported in Flex. Now, if you haven't done that, that implies that your app is pretty muc script-driven, in which case the best option is probably just to copy the script into .as files and compile them from MXML. --- In flexcoders@yahoogroups.com, Dennis Baldwin [EMAIL PROTECTED] wrote: We're in the process of porting some of our existing RIA functionality from Flash to Flex.

It is more of a document-scope issue. Each MXML file is its own

You might have better luck using an ASComponent subclass of
RadioButton as the cellRenderer. Create a .as file that looks sort
of like:

RE: [flexcoders] Re: Flash V2 Components and Flex Compatibility
Alex, Thanks for your prompt reply. As it currently stands our components are instantiated non-dynamically (ie from within the Flash IDE). Since we basically design the view in the Flash IDE and register with our controller (AS 2.0 class) then it probably won't take much to refactor intothe Flex framework. Now that I have a definitive answer I can explore the option you suggest.

It instantiates all of the components on-the-fly. In Flash one can easily place components on the stage or in other symbols. If you did that, it probably won't run in Flex as that is non-dynamic and the instantiation sequence in that case is not supported in Flex.Now, if you haven't done that, that implies that your app is pretty muc script-driven, in which case the best option is probably just to copy the script into .as files and compile them from MXML.--- In flexcoders@yahoogroups.com, "Dennis Baldwin" [EMAIL PROTECTED] wrote: We're in the process of porting some of our existing RIA functionality from Flash to Flex.

Re: [flexcoders] Re: TreeDataProvider implementation
I think the main reason I think I need to make my own TreeDataProvider is that the CF object persistence backend I'm integrating with requires that I send back deleted objects with a property, deleted=true. So there will be a bunch of objects which I don't want to show in my tree data with deleted=true. In my last tree I also had trouble where date objects were being appended to the label property, and I couldn't 'hide' anything in the 'data' object. I ended up writing a separate object to store my complex data, then parsing it into a simple object which is assigned to the tree. Any commands from the tree then just referenced the 'bigger' object by id values in a hash table. I don't think I can really do that this time, since it is pretty important for the tree's data source to actually have a bunch more information than is shown in the tree.What other options do I have? I hate to say it, but I find the documentation very confusing on using the Tree to represent and modify complex nested data structures. My main goal is to have my main value object be the one assigned to the tree, but with the flexibility to manage which folders are opened, what labels are shown, and what sub-objects are hidden.Thanks,SeanOn Jun 13, 2005, at 11:05 AM, alex_harui wrote: TreeDataProvider is advanced stuff.

Thanks for your help...I've finally identified the problem (but

siblingPojo back to my MainPojo, commenting out that code did not
solve the problem. However, my SiblingObject has an attribute that
is part of a class with static variables. So to give you an
example,
my SiblingPojo has an attribute like this:
private Status status = null;
When I construct my data objects in the back-end, I set this
variable using it's own static data:
siblingPojo.setStatus(Status.CONFIRMED);
Here's the Java code of the class that the serialization is
hanging
up on. This is a pretty standard j2ee design pattern. You'll see
that I only have a private constructor. This is what ensures that
the variable data will be constant throughout the app. If I were

[flexcoders] Re: odd behavior...
Hi, this is because you are making the web service call and then
setting the playerInfo instantly, without waiting for the result of
the web serivce.
The Flash player doesn't block (stop and wait) after you give the
podData.send(), it simply starts the call then continues executing
your code. And the result property of the service hasn't been set yet
so you don't see it after the first call, and it hasn't been re-set so
you see the result of the first call on the second try, etc etc.
You have to use the result event of the service, something like this:
mx:HTTPService id=podData url={podURL} useProxy=true
showBusyCursor=true result=playerInfo=podData.result.rss /
You should also handle the fault event so if it fails it does so
nicely. And of course you should probably have the code in a method
rather than right in the service declaration...
Hope that helps.

yes. we're going to plan to stub it in as a constants until 2.0 is

Pete-
Thanks for your help...I've finally identified the problem (but
still not the solution). Although I did have a reference of my
siblingPojo back to my MainPojo, commenting out that code did
not
solve the problem. However, my SiblingObject has an attribute
that
is part of a class with static variables. So to give you an
example,
my SiblingPojo has an attribute like this:
private Status status = null;
When I construct my data objects in the back-end, I set this
variable using it's own static data:
siblingPojo.setStatus(Status.CONFIRMED);
Here's the Java code of the class that the serialization is
hanging
up on. This is a pretty standard j2ee design pattern. You'll see
that I only have a private constructor. This is what ensures
that
the variable data will be constant throughout the app. If I were
to
add a public constructor, the class would not compile (since my
variable 'type' could technically never get instantiated)...I'm
guessing the serialzation is hanging b/c there is no public
empty
constructor?
have you ever come across a situation like this before?
Thanks again for your help.

I assume it's a http service you're using that calls the PHP page to get the IP? I think the web service calls are proxied by default.

[flexcoders] Remoting peformance for large lists
Hi all, We're having some peformance problems on the client side when loading large lists of object graphs through our remoting inteface. I've written a simple test case to characterize the problem (the mxml file and remote object are attached), and I'm seeing some behavior I can't explain. I would appreciate any help anyone can provide understanding the problem or providing work-arounds. The time between the remote method call and the resultHandler of the call grows linearly with list size and/or object size as you'd expect. We're also seeing a period of time after the result handler where the application becomes unresponsive. This is what I can't explain. This mystery time increases non-linearly with item count and seems to increase greatly when items in the list reference other objects (even if they all reference the same instance). I've traced data from within the result in the resultHandler, so the action script objects seem to be fully serialized by the resultHandler, so the clients peformance after the resultHandler doesn't seem to be directly hampered by object loading or creation. The attached graphs show the results of my tests. In each graph the time until the result handler is in orange, the time after the result handler is green and the sum of the two is blue. TOP LEFT: Load time per item where each item contains a map with 5 entries. Note that the mystery time (green) increases non-linearly, and (excluding the spikes) the orange increase linearly. TOP RIGHT: Load time per item, 10 entries. The orange lines slope increases as you'd expect since the size of the objects have increased by ~80%. The green line is identical to the graph of items with 5 entries. MIDDLELEFT: Load time per item, 20 entries. Again the orange line's slope increases as expected. The mystery time remains the same. MIDDLE RIGHT: I modified the remoting code to create a single parent item and give each item in the list a reference to it. I then created a second parent object so that each object would have a reference to 2 parent objects (but only a single instance of each). I overlayed the graphs so that the scales matched (each item had 10 map entries and the bottom lines are test graphed in the TOP RIGHT). Note that adding the one reference increases the mystery time by nearly 100% and adding the second reference increases it by 150%. BOTTOM LEFT: Load time per map item, 1000 items. Holding the items constant, you can see that the mystery time holds constant after a certain point, and the load time (orange) increases linearly with object size as expected. BOTTOM RIGHT: Repeated calls for 0 items. This is a control to eliminate the possiblity that multiple calls or the graphing was responsible for the slowdown. Thanks, Alex Carbon Five Yahoo!

head

%@ taglib uri=FlexTagLib prefix=mm /
%
String ipAddress = null;
if( request.getHeader(X-Forwarded-For) == null )

else
{
ipAddress = request.getHeader(X-Forwarded-For);
}
%
body
mm:mxml source=myApp.mxml
mm:flashvar name=IP_ADDRESS value=%= ipAddress % /
/mm:mxml
/body
/html
Be sure to have the variable IP_ADDRESS declared in the root of your
mxml application.

[flexcoders] Re: Popup windows behaving oddly
I have had similar experiences where a popup appears to be shown
behind the application, and by having modal transparency set, you can
see that the popup method is called because the application dims out.
I have also played with popups from an application loaded within
mx:Loader and have also had weird behaviour.
As a result of these my createPopUp method uses _root as the parent

mx.core.Application.application ...
maybe try the following:

{
var popup = PopUpManager.createPopUp( _root, window, true, vars, true );
popup.width = w;
popup.height = h;
popup.centerPopUp( MovieClip(mx.core.Application.application) );
}
In the above showPopUp method I pass it the popup window, an init
object (if neccessary), and a height and width.
Try it and see how it goes,

1) They popup behind the window which created them.
Did you pass 'this' as the first argument to
PopUpManager.createPopUp() from the window that created them? You
need to specify the parent of the popup window. Make sure you got
that right.
2) They pop up in the upper left even though we asked them to be

Again, did you pass 'this' as the argument to centerPopUp() ?

You could also pass it to your mxml file as a flashvar, as long as you

similar to the following from within a jsp page:

mm:mxml source=myApp.mxml
mm:flashvar name=IP_ADDRESS value=%= ipAddress % /

Be sure to have the variable IP_ADDRESS declared in the root of your

Re: [flexcoders] Remoting peformance for large lists
Hi Matt, I have read (and now re-read) your excellent large data articles (which are now well established within the Flex literature's cannon). This exercise was an attempt to squeeze all the performance out of our requests before we implement paging and to try to establish an optimum page size. I wanted to try to make some addtional improvements because I was afraid that (assuming performance declined linearly) loading small chunks of data would still make that application to unresponsive. This seems to be a poor assumption in the case of our actual problem. I'm still curious as to why deserialization performance decreases non-linearly with item count (but not item size), why common object references affect the load time, or why there is a significant period *after* the resultHandler during which the client becomes unresponsive. Any help with these questions would help set my mind at ease. Thanks, Alex On 6/13/05, Matt Chotin [EMAIL PROTECTED] wrote: Have you ready my large data articles?

Hi, this is because you are making the web service call and then setting the playerInfo instantly, without waiting for the result of the web serivce. The Flash player doesn't block (stop and wait) after you give the podData.send(), it simply starts the call then continues executing your code. And the result property of the service hasn't been set yet so you don't see it after the first call, and it hasn't been re-set so you see the result of the first call on the second try, etc etc. You have to use the result event of the service, something like this: mx:HTTPService id=podData url="" useProxy=true showBusyCursor=true result=playerInfo=podData.result.rss / You should also handle the fault event so if it fails it does so nicely. And of course you should probably have the code in a method rather than right in the service declaration... Hope that helps.

Here's the oddness: the component displays only the data from the PREVIOUSLY selected item that calls the event. So for example, if the user clicks a, the HTTPService is called, but no results are displayed in the display component. However, then the user clicks b, and the contents of a appear. Ideas?

Pete-
Thanks for your help...I've finally identified the problem
(but
still not the solution). Although I did have a reference of
my
siblingPojo back to my MainPojo, commenting out that code
did
not
solve the problem. However, my SiblingObject has an
attribute
that
is part of a class with static variables. So to give you an
example,
my SiblingPojo has an attribute like this:
private Status status = null;
When I construct my data objects in the back-end, I set this
variable using it's own static data:
siblingPojo.setStatus(Status.CONFIRMED);
Here's the Java code of the class that the serialization is
hanging
up on. This is a pretty standard j2ee design pattern. You'll
see
that I only have a private constructor. This is what ensures
that
the variable data will be constant throughout the app. If I
were
to
add a public constructor, the class would not compile (since
my
variable 'type' could technically never get
instantiated)...I'm
guessing the serialzation is hanging b/c there is no public
empty
constructor?
have you ever come across a situation like this before?
Thanks again for your help.
public class Status{
private final String type;
private Status(String type) {
this.type = type;
}
public String toString() {
return type.toString();
}
public static final Status UNASSIGNED = new Status(UNA);
public static final Status ASSIGNED = new Status(ASG);

address
You could also pass it to your mxml file as a
flashvar, as long as you
have the variable declared in your root
application. I do something
similar to the following from within a jsp page:
!-- index.jsp --
html
head
titleflex/title
%@ taglib uri=FlexTagLib
prefix=mm /
%
String ipAddress = null;
if(
request.getHeader(X-Forwarded-For) == null )
{
ipAddress =
request.getRemoteAddr();
}
else
{
ipAddress =
request.getHeader(X-Forwarded-For);
}
%
body
mm:mxml
source=myApp.mxml
mm:flashvar
name=IP_ADDRESS value=%= ipAddress % /
/mm:mxml
/body
/html
Be sure to have the variable
IP_ADDRESS declared in the root of your
mxml application.
Hope this helps,
Andrew

Hi,
I do this with a simple .jsp script in the
Flex app. You can include
something like the following:
getIPAddress.jsp:
clientip
valGet%=request.getRemoteAddr()%/valGet
/clientip
Then call that within Flex in an HTTPService
and parse the return.
HTTPService.result.clientip.valGet , etc
Then you can store that in a sharedobject or
whatever you want.
Hope it helps.

I assume it's a http service you're
using that calls the PHP page to
get the IP? I think the web
service calls are proxied by default.
Try adding the
useProxy=false property in the http service, that
should tell the app to go to the web
service directly.

We've got a Flex app that is
calling a PHP script to retrieve the
end-user's IP address (for an
authentication procedure), but the
IP
address that is returned is the
address of the Flex server, not
the
client. Any thoughts on why
this is happening? And, how do we
work
around it?
