[flexcoders] SOAP requests and arrays being collapsed into "val1,val2,val3"... Any ideas?

[Josh McDonald]

Hi guys,

I've got something that should be going out like this:



 ALLOC005is1
 Noveaux


but what I'm getting in my message is this:



 ALLOC005is1,Noveaux


Is this something you've come across before? Any ideas? Even any ideas what
I should be looking for?

[flexcoders] Re: Modules the way to go?

[Daniel]

That's the problem... I won't develop the modules that will be running
in the desktop manager... I'll only load them and unload them... But I
want to make sure the application runs fast...

Are there any tricks or tips to ensure the modules run fast and
release unused resources? 

If I have several small modules opened (say 6 to 10, each of 20K to
60K size), they shouldnt crash or overload the browser?

Have your classfactory only return one instance.

[flexcoders] Query on SWC

[Sudha Hariharan]

Hi,
 
I have created a SWC file of various components. Adding the
SWC to Flex Builder project makes the components visible in the Components
Window (in Flex Builder) under the folder named Custom. Instead I would like to
display it under a different category in the Components Window. Also some of
these components have certain properties that would appear in the Properties
view. As of Flex Builder 2, this Meta data had to be stored in xml files within
Flex Builder plug-ins. However, I believe that there are easier ways to do the
same using Flex builder 3. I think some of this meta data can be added to the
swc file itself. Could anyone throw some light on how this can be achieved? 
If not in Flex Builder, are there any other tools or
procedures that can lead to an easier solution?
 
Thanks & Regards,
Sudha.

What about storing an array of Image components in the array rather than 
the urls... put them all on the canvas and the just set visible for the 
one you want to display. I had to do a similar thing once when i wrote a 
flex lake applet.  YMMV.

This seems so dumb, but I can not figure this out.

I am using Modules with layout="absolute".

In a MXML file I have a TextArea where I have set the width="300" and
height="35".



I can add text beyond 2 lines, but no scroll bar is displayed.

If I set the height="100%" then the scroll bar shows up when I type text
beyond 2 lines.

I can also place it inside a VBox and set height="100%", but that just adds

However, I want/need to set the TextArea's height.

What am I missing? Is there a simple way?

Agreed.

Also, I don't like being restricted to only being able to register
events types to command classes to a Front Controller that is created
in the view.

Registering the controller in the view means to reference it at
runtime i have to go through the view.

Common sense tells me in MVC it would be better if the controller was
created by the model, not the view.

[flexcoders] MessageBroker won't return control after routeMessageToService()

[jfujita1]

Well, Here is the report after I've traced the errors down.

I've noticed that when my custom java message adapter halts BlazeDS'
messaging still runs.  Several diagnostic applications indicate the
durability of BlazeDS messaging.  

I have however tracked down the source the halting of my java message
adapter thread to be the MessageBroker...

My custom message adapter is multithreaded in that it manages two
tasks: One thread listens for messages from a server and then starts a
"fire-and-forget" messaging thread that then packages and routes the
message into an AsyncMessage for broadcast to BlazeDS before dying.  

Traces indicate that after about 6 days of reliable message routing
the messaging threads generated by my listener thread start halting at
the msgBroker.routeMessageToService(msg, null); method call. (Trace
statements to console halt after "Trying to routeMessageToService").

public void sendMessage()
{
System.out.println(name+" Connecting to MessageBroker");
msgBroker = MessageBroker.getMessageBroker(null);
System.out.println("MessageBroker.getId() = "+msgBroker.getId());
String clientID = UUIDUtils.createUUID(false);
msg.setClientId(clientID);
msg.setMessageId(UUIDUtils.createUUID(false));  
msg.setTimestamp(System.currentTimeMillis());
System.out.println(name+" Trying to routeMessageToService");
msgBroker.routeMessageToService(msg, null);
System.out.println(name+" Successful message route");
}


That is to say that msgBroker's routeMessageToService() method call is
not returning and the messaging threads are all halting and piling up
in the JVM.  After about 4000 of these halted messaging threads piling
up the JVM runs out of memory and the listener thread can't
instantiate any more messaging threads and the whole thing comes to a
halt.

You can say that my problem is thus: MessageBroker's
routeMessageToService() method stops returning control to my message
thread after about 6 days halting it until the unsent message threads
pile up leading up to an out of memory crash.  

I'm working on a fix that will kill the halted message thread if it
runs longer than a few seconds.  This should aleviate the thread
traffic jam but I don't know if the MessageBroker will start routing
messages again.  I don't know why it stops either.


Hope you could shed some light on this.

Best,
Justin

Fwd: [flexcoders] Re: AdvancedDataGrid preserve openItems after data update

[jonese]

OK here's what i did to keep my nodes open.

un my update function i call preventDefault() to stop the expected operations.

then i manually build using updated data my object instances
then search the original objects till i find my matching object
overwrite the orginial object with the new instance
then run a refresh() on the dataprovider.

This appears to be working for me and it is having the expected
results.so far :)

RE: [flexcoders] TextArea but no scroll bars showing up

[Jack @ Zingit]

Tracy:
 
Yes that will work, but I only wanted the height to be 35, which
allows for 2 lines.  The reason is "screen real estate".
 
If I set it the Canvas height to 35, then I get horizontal and vertical
scroll bars showing up before I even type anything.
 
The lowest number I can go is 44.
 
Jim's research seems to indicate a hard-coded issue if the TextArea
is less than 40(Flex 3).
 
override public function get verticalScrollPolicy():String

{

return height <= 40 ? ScrollPolicy.OFF : _verticalScrollPolicy;

}

 
I guess I will need to step back and rethink.
 
I was beginning to think I was going crazy.
 
Anyway, guys . . . . thanks for the help.

Flex 2.01

This seems so dumb, but I can not figure this out.

I am using Modules with layout="absolute".

In a MXML file I have a TextArea where I have set the width="300" and
height="35".



I can add text beyond 2 lines, but no scroll bar is displayed.

If I set the height="100%" then the scroll bar shows up when I type text
beyond 2 lines.

I can also place it inside a VBox and set height="100%", but that just adds
unnecessary code. That also causes other positioning problems.

However, I want/need to set the TextArea's height.

What am I missing? Is there a simple way?

Thanks,

RE: [flexcoders] TextArea but no scroll bars showing up

[Jim Hayes]

I thought you were setting the text programatically, rather than typing, 
apologies for that.

I just checked it (in flex 3), if the height of the textArea is greater than 40 
pixels then scrollbars do appear when you type, but not if <= 40.

If you look at the source for textArea it appears that this is hardcoded :

override public function get verticalScrollPolicy():String
{
return height <= 40 ? ScrollPolicy.OFF : _verticalScrollPolicy;
}


I can only presume to allow at least some space for the scrollbar to be 
rendered.

If it *has* to be 35 pixels high then you could try extending textArea I 
suppose, otherwise try 41 !

RE: [flexcoders] Re: datagrid using button or checkbox wHat Code to Trigger

[Tracy Spratt]

Yes, this is the way to do it in a real app, and is the way I do it, by
building an update message that I send to the server.

 

Jason and I have been through all of that in this thread, but he was not
receptive to that level of advice, and his last question was simply:

"How can i remove an item from the data grid using action script?"

So that is what I answered.  I'd have given more detail, but he has not
said what his dataProvider is Hint, Jason.

It might be better to mark the item as removed in the dataProvider, 
since that will probably make it easier to do the delete operation on 
the server. After that (correct me if I'm wrong--this is all 
theoretical to me), you'd need to filter the dataProvider to only show 
the items that have not been removed. The last step would be either 
using the dataProvider's source to send to the server or removing the 
filter.

RE: [flexcoders] TextArea but no scroll bars showing up

[Jack @ Zingit]

Jim:

I am not sure what you mean with the TextArea.validateNow().

Are you saying I have to call some function to get the scroll
bar to display?

I guess the question is why is it not showing up?

I only happens when I set the height to a number instead of
a percent %.

Is this bug?

I have found no documentation that says the scroll bar will
only appear if is contained within a container and/or the
height is set to a percentage.

Everything I have read says this should work, but I wonder
if it is because I have layout="absolute".

I will continue to research.

Any guidance will be greatly appreciated.

Thanks,

Jack

"Once a month this issue comes up.  Because there is no function
olverloading in AS3, we can't change the parameter list of addChild, but
basically, frameworks have rules and the rules for Flex are:

 

Navigator children must be Containers

Container children must be IUIComponents

UIComponent children can be anything.

 

I swear I replied to this thread two days ago, but answer is to
instantiate a UIComponent and addChild your sprite to it.

Alex has posted these rules multiple times.   Something like:

you are adding?

 

Alex has posted these rules multiple times.   Something like:

Container can accept container or UIComponent, UIComponent can accept
anything, ... etc I do not know whare sprite fits into that.

Re: [flexcoders] Re: CartesianDataCanvas not drawing where expected

[Aaron Miller]

Thanks! I actually tried the LinearAxis to begin with, but gave up on it
after my first attempt since it didn't seem to work right. Since the
CategoryAxis worked right away, I didn't explore the issue any further.
After playing around with the LinearAxis some more, I got it working the way
it should. CartesianDataCanvas now plots like a charm.

Thanks again for the help!

Try yourTextArea.validateNow() after adding the extra text.

This seems so dumb, but I can not figure this out.

I am using Modules with layout="absolute".

In a MXML file I have a TextArea where I have set the

I can add text beyond 2 lines, but no scroll bar is displayed.

If I set the height="100%" then the scroll bar shows up

I can also place it inside a VBox and set height="100%",

However, I want/need to set the TextArea's height.

RE: [flexcoders] Combo Box trying to get a "deep" data...

[Tracy Spratt]

Setting a ComboBox to show a selectedItem is not built-in.  You will
need to loop over the dataProvider for the CBO droplist, compare the
current value to the value in the appropriate dp item property, then use
the loop index to set the selectedIndex.

 

This is not difficult.  If you need to do it a lot, extend combobox.  I
have an example of this on www.cflex.net  .  Note
that it is a bit complicated, because I wanted to be able to get the
comboBox options from either the  dataProvider item itself or from an
external DP.  The issue is further complecated because one must be able
to specify which property in the droplist dataProvider to use to compare
values.

 

A "one-off" for a specific use case is much simpler.  Probably that is
why this is not built-in.

[flexcoders] Checkbox as a headerRenderer

[markgoldin_2000]

I am implementing a checkbox as a headerRenderer:
public class CheckBoxHeaderRenderer extends CheckBox
{
public function CheckBoxHeaderRenderer()
{
super();
addEventListener("click", clickHandler);
}
override protected function clickHandler(event:MouseEvent):void
{
super.clickHandler(event);
}
}
I need to be able to communicate to a column that would have that 
header. I need to enable/disable it, as well as reset column's data. 
Any idea? 
Thanks

[flexcoders] Fast updating of image.source

[Roger Howard]

I've got a sequence of images loaded in Flex - for this example let's 
say I've populated an array ("imageArray") with new Image objects.

I've got an Image control ("myImage") whose source is set on 
applicationComplete.

During the application run, I'd like to be able to set the source of the 
image control dynamically (in this case, based on mouse position) to the 
source of one of the objects in the array. For instance:

myImage.source=imageArray[0].source;

The problem is, when I change image source there's a brief flash (no pun 
intended) when the image control updates - it seems to briefly show the 
background of the parent control (in this case a canvas with a solid 
color). This makes for a jarring transition between each image as it's 
loaded.

I get the same effect even in the simplest of cases - just setting 
myImage.source explicitly, forgetting about the array.

How can I update the source of an Image control without this strobing 
effect? Or am I going about it the wrong way?

My Flex experience is limited to a few months of frontend UI development 
- lots of data binding and layout - and this is a new one on me.


Thanks for any help,

Roger Howard

[flexcoders] Re: How do I add a header or additional post parameter to a RemoteObject Request

[valdhor]

Just send an object as the parameter that you send:

var myService:RemoteObject = new RemoteObject();
myService.source = "myServices.MyService";
myService.destination = "amfphp";
myService.requestTimeout = 30;
myService.addEventListener(ResultEvent.RESULT, myResult);
myService.addEventListener(FaultEvent.FAULT, faultHandler);

var myParameters:Object = new Object();
myParameters.data1 = "data1";
myParameters.data2 = "data2";
myParameters.uniqueToken = "myUniqueToken ";
myService.getOperation('getMyStuff').send(myParameters);

[flexcoders] Pay-to-Play Credit Card Processors

[nagaofthesea]

Hello All-

I am prototyping an online application that will require users pay-to-
play.  That is, users can purchase chunks of time to gain access to the 
application's functionality.

My application is being developed using Flex3 on the front, ColdFusion8 
in the middle and SQL Server 2005 on the back.  Ideally I would like to 
integrate cc payment seamlessly.  If the user gets close to running out 
of time they can quickly purchase with a stored profile and then 
seamlessly pick up where they left off.

Does anyone have experience with vendors who provide plug-in cc 
processing service or shrink-wrapped components for this kind of pay-to-
play functionality? Easy integration with the Flash Player 9 a BIG BIG 
plus, but not necessary.

Thanks And Regards

RE: [flexcoders] Re: datagrid using button or checkbox wHat Code to Trigger

[Tracy Spratt]

Ignoring LCDS and Blaze DS (which perhaps you should look into), Flex
can pass data to the server via the same protocols that it gets it,
namely WebService, HTTPService or RemoteObject. Since you used the word
"POST", presumably you are using HTTPService.

 

What you pass over that protocol is up to you, but is most often xml.

 

If your dataProvider is XML (or is an XMLListCollection backed by XML),
you can send the data to the server by doing:

myService.contentType = "application/xml"

myService.send(xmlData);

 

Note: I typically use the default content type and do:

myService.send({xmlstring:xmlData.toXMLString()}); //then parse the xml
string on the server.

 

But that opnly gets your data to the server.  Aside from LCDS or
BlazeDs, there is no built-in functionality to determine what needs to
happen with that data on the server.

[Tracy Spratt]

If your dataProvider is a Collection, you can call
collection.itemUpdated(...)

When typing in a datagrid cell, I am capturing the datagrid's change
event and then making calculations on other cells in that row. 

I've used both invalidateList and invalidateDisplayList after I make
my calcs but it doesn't seem to update the text in the grid until I've
tabbed out of that cell and tabbed out of a second cell. 

I would really like to do the calcs and see them update in the grid as
I'm typing. 

Is there a better approach to for this?

I do not do PHP, but it sounds like you are going to need to learn it.
Perhaps you should find a PHP forum/list, since that work does not
involve Flex.

What is your PHP code expecting?  How does it know if a "row" is to be
inserved, deleted, or updated?

[flexcoders] itemUpdated() functionality for XML properties?

[Tracy Spratt]

 I have a bindable data model implemented as a singleton, several
properties of which are implemented as XML.  My app uses binding and
ChangeWatchers to respond to changes in this XML data.

If I assign an entire xml to one of these properties, the property
change is dispatched and my bindings fire and my watchers are called.

But if I update an item in the xml, like set and attribute value or text
node, it APPEARS that the events are not dispatched.  This is
unsurprising, as it is analagous to updating an item property in a
Collection, for which itemUpdated() method exists. 

First, is the behavior I am seeing is expected?  I know that XML
dispatches ordinary events that fire bindings, but those events are not
getting out of my model instance.  Second, if the behavior is expected,
is there some similar itemUpdated() functionality for XML?

Tracy

RE: [flexcoders] Combo Box trying to get a "deep" data...

[Tracy Spratt]

Oops, maybe misread your question.  You are not asking about accessing
deeply nested values, but rather how to set the combobox selectedItem to
match its current value?

 

Or maybe you are just asking about declaring "dataField"?

[flexcoders] removing items from a bubble chart

  Hello,

  I have a bubblechart where I use button as itemrenderer.
  Once the chart is created the same rendered items are shown
  even though the [Bindable] dataprovider is changed but the
  number of item that are shown in the chart reflects the
  change. I guess I need to remove all the existing child and
  then assign the updated dataprovider. How do I remove the

RE: [flexcoders] DataGrid CustomItemRenderer Issue

[Tracy Spratt]

Item renderers are recycled, and must be entirely data-driven.  When you
add your child, you must update some property of the dataProvider item,
say, [EMAIL PROTECTED] = "true".

 

Then in your set data() override, use the value of that property to
decide whether to either add or remove the text child.

RE: [flexcoders] datagrid using button or checkbox wHat Code to Trigger

[Tracy Spratt]

The best way is to have the change or click of your checkbox or
button(toggle?) update the associated dataProvider item.  Easy with XML,
just set an attribute, like [EMAIL PROTECTED]"delete".

 

When you  are ready to update the server, get the modified rows (again
easy with e4x), and build your update message.  That message depends on
your back -end.

[flexcoders] Child items in custom component

[Weyert de Boer]

Hello!

I am currently a bit clueless regarding using Flex components. I am 
currently trying to port a .NET component to Flex. Only I have some 
problems. In a simplified form the problem is that I am trying to add 
childs to the component. The idea is to use public method to add nodes 
to the component. The code could be:

var node: MyNode = new MyNode();
node.width = node.height = 125;
myComponentInstance.addNode( node );

The addNode-method is basically contains:
   
public function addNode( node: MyNode ): void {
_nodeContainer.addChild( DisplayObject(node) );
invalidateDisplayList();
   }

The _nodeContainer is a Sprite class which gets created in the overriden 
createChildren-method. Now I would be expected that the MyNode-instance 
(which just draws a simple rectangle 125x125) would be shown. Sadly 
enough, this is not the case.

Does anyone know what should be done to get this working?

Yours,
Weyert de Boer

Re: [flexcoders] Where can i find flex 2 installable?

Try searching the Adobe site for the Flex 2 SDK with Google (or another

limit the search to a single site. I found

http://labs.adobe.com/technologies/flex/sdk/flex2sdk.html

which seems to be what you want (and also offers nightly builds).

Ok i managed to get the problem sorted.

Previously, I had to do this will alot of my own AS classes (and a 
few from the Flex framework), but now i am using an RSL (where most 
of the classes exist) it was not necessary to create any of the dummy 
instances of the classes... or so i thought!


Well that seems to be the problem solved, thanks for your pointers

I have a datagrid which has customItemRenderer. In the itemRenderer I have a
button which onClick adds a child label to the itemRenderer.
Now,in the application, when I click on an item's button a label is added to
it. Then I scoll down and (don't know why?) find this label added at random
itemRenderers.

*Here is the sample application:-*

http://www.adobe.com/2006/mxml"; layout="absolute"
xmlns:local="*" creationComplete="onCreationComplete(event)" >














*Here is the itemRenderer:-*

http://www.adobe.com/2006/mxml"; height="100%"
width="100%">










Please help finding me the problem.

Thanks and Regards,
Sunny Ladkani

begin to put code behind them.
I've got all my code to handle showing my button and checkbox but no

while i find many demos showing itemrenderer i just cant seem to find
any showing examples with interaction on a code level to what im looking

anyone know a good example

Re: [flexcoders] Re: Use Cairngorm wihtout Dispatch

[Stephen Downs]

I'm not saying it's a major problem that we come across often, but  
when taking on other people's work, or working as a team it's  
something we have come across. We would expect all vars, methods,  
class, events to be named well, but we find it more efficient to  
error the project through changing a method name, than to do a find  
in files. We want to keep things as simple as possible.


The point I was making as that just because events are used on the  
view instead of it accessing controller methods directly it doesn't  
necessarily de-couple them, since in most cases the view is relying  
on its events being picked up and acted upon. If my previous  
statement is true for you and your team, there's really no need to go  
down the event road, as it does introduces more complication and with  
it more time to implement.


Just to clarify we don't take this approach on components, but we do  
for views/screens.

I've not really had those problems myself Tink.

I don't dispatch any standard cairngorm events, instead I have  
events that extend it and are (usually!) fairly well named to  
reflect what's happening.
Maybe that's because for me they normally carry some data, and I  
like that data to be as strongly typed as is practicable.
The command/delegate will usually follow the same naming, so I may  
have SaveBitmapEvent + SaveBitmapCommand + SaveBitmapDelegate, for  
example.
So to find any particular event dispatch in my view, it's pretty  
easy to do a "find in files" on the project, though in practice I  
find I rarely need to.
Likewise, finding the command it calls is pretty easy for the most  
part, as is the implementation in the delegate.


Good point on the controller not listening, but I guess I've just  
got used to writing a shell version of my command, breakpointing  
it's constructor and checking it does get called when I expect it  
to before proceeding to fill in it's implementation. If not, then  
the frontController has it's fingers in it's ears shouting na na na  
I can't hear you :)


It would be good if it could catch all cairngorm events and raise a  
warning if they were not registered, though. I have a feeling it  
wouldn't be too hard to extend it do that, but I've never felt the  
need myself.


I'm sure we're both thinking "don't make me have to think too hard,  
if at all", and I'm in broad agreement with you, but the 3 classes  
and controller entry approach does work for me (even if it is very  
tedious to write at the time).

I have to agree with MichNiu here.

The CairngormEventDispatcher obsfucates the code. i.e. you come back
to a project 6 months down the line, its difficult to find in the
view where your CairngormEvents are dispatch.

What is the difference of the view knowing what event it has to
dispatch, to it actually knowing the method on the controller it was
to invoke? Very little in my opinion, but the later enables you to
very easily pinpoint all the calls from the view to a method on the
controller, by just changing the name of the method on the
controller, and looking at all the errors that will appear on the
view. This makes things much easier to debug and therefore easier to
maintain.

You talk about making views re-useable, but if your view is
dispatching CairngormEvents, you can guarantee it's relying on some
action of the FrontController for it to work properly. If you
FrontController doesn't listen to these events, your view won't work,
therefore it aint re-usable, its relying on the FrontController
acting upon the events is dispatches.

We still keep a Controller unlike MichNui's implementation, but we
cut out the use of CairngormEventDispatcher some time ago.

Now when it comes to re-usable components, thats a different matter.

[flexcoders] addEventListener() for File.createDirectory(). How to use?

[Carlo Gulliani]

Hello, everybody!

How to use addEventListener for File.createDirectory() on Adobe AIR?

I write code:

var dir:File = new File("e:\\").resolvePath("myDir");
dir.createDirectory();
dir.addEventListener(Event.COMPLETE, someFunc); // Tooltip show me that this 
event i can use for my parameter and I want to check if my new Directory 
created then call someFunc()
function someFunc(event:Event):void{
var file:File = File.desktopDirectore.resolvePath("test.jpg");
var newFile:File = dir.resolvePath(file.name);
file.copyTo(newFile, true);
}

but this code doesn't work. my someFunc doesn't execute. I see, my folder 
creating with some pause, I get new folder after 2-3 seconds after execute 
function and I want to check when my folder is created and after it copy to it 
some files

[flexcoders] flash9 and sizes

[Marcus Engene]

Hi,

I use as3 + sdk + FlashDevelop to do swf:s, currently trying Flexbuilder 
as I eventually would like to start using mxml.

I am not completely sure how coordinates and sizes work. Say that I have 
a root Sprite 100x100 large; a child Sprite at x:50,y:50 of size 50x50. 
It seems that flash calculates a viewport of the child sprite and 
maximizes it to fit into the 50x50. So if the child sprite only contains 
a 10x10 bitmap, this bitmap will be rendered of size 50x50 in the root 
sprite.

The root sprite did seem to bahave like this too until I got the advice to
this.stage.scaleMode = StageScaleMode.NO_SCALE;
this.stage.align = StageAlign.TOP_LEFT;

In short, I've managed to confuse myself gravely and wonder if any has 
any reading suggestions?

Thanks!
Marcus

[flexcoders] Flash/Flex Component Kit and Dynamic Loading

[swidnikk]

I'm working with the Flash/Flex component kit and I have created some
swc and swf files with a base class of UIMovieClip. 

All of the tutorials I've seen/read describe using the swc file to
instantiate the Flash component in a Flex component. 

I have an application that requires these components to be loaded
dynamically so I'm using a loader object to do this and I use the
class name of the symbol that is exported in the SWF to instantiate
the symbol. 

So far so good. My problem arises when I try to add an instance as a
child to a Flex container. mxmlc throws a 'type coercion error' that
my UIMovieClip does not implement IUIComponent.

Reading flashdocs and flex component kit docs, however, it clearly
state that UIMovieclip objects can be used just like any native Flex
component. 

My work around at the moment is the create an intermediate
UIComponent, add my Flash symbol instance as a child and then add this
UIComponent as a child to the panel. This is okay for now but makes
several things more complex. 

Anyone know what this is all about?

Also, I've tried to dynamically load a SWF to be used a skin for a
button, but this seems not possible. Can anyone verify if this can be
done at all?

Thanks.

Try using a NumericAxis instead of CatagoryAxis, you generally use
catagoryaxis if the data, is in chunks, like months of the year and such. 

[flexcoders] Where can i find flex 2 installable?

[baztheman]

Hi,

I had some tests need to be done with flex 2 and somehow we manage to
damage the original machine that installed with flex 2.

My question is: where can i get the installer for flex 2? The Adobe
site changed everything to Flex 3 and i could not locate Flex 2 archive. 

Thank you.

Subject: [flexcoders] Dual DataService components causing problems

 

Hi,

i have developed a modularised application in Flex 2.0.1 (hotfix 1) 
and im having some problems with the DataService tag.

I have a module in the application's side bar which fills a 
collection with managed objects, and i also have a module in the main 
application area which fills a collection with managed objects.

Each module uses different assembler classes/destinations configured 
in the data-management-config.xml file.

When i perform a fill on the each collection, and then attempt to 
perform another fill on the side bar module, i keep getting errora 
from the flash player log file.

The collection in the main application area always refreshes without 
any problems

The error from flex...

TypeError: Error #1034: Type Coercion failed: cannot convert

might have made to cause these issues.

[flexcoders] Re: Dual DataService components causing problems

[Barry Evans]

Thanks for that Seth, its definately a step in the right direction.

I have now removed the fds.swc from the module project's build path 
but i am getting a few compilation errors on VO classes i have 
defined to be used in the managed collection of objects...

1045: Interface IManaged was not found

I think this is why i had to add the fds.swc to the project in the 
first place.

Thanks again for your suggestions and if you can think of anything 
else i would appreciate it.

Barry
