[flexcoders] I want to create a custom ComboBox with general itemRenderer.
I have comboboxes that might take in different item renderers depending on the situation. The problem I'm facing is showing the selected item on the Combobox label. I want to show it exactly same as to the item showing on the dropdown list. I found somewhere that i should remove the textInput from the Combobox and addChild with a new renderer instance. however I couldnt find a clear solution to this. Any tips on where i should start?
RE: [flexcoders] Binding Model Objects
Having your DTOs physically different from your Domain Objects has a lot of benefit using the assembler pattern to map between the two. You can have entirely different structures for your DTOs, map multiple DOs to DTOs, keep your transport and domain layers separate (also allowing you to use different transport mechanisms AMF or XML over HTTP both easily swapped), and allow you a great deal of flexibility in structuring your application. Downside, yes the conversion process can be expensive, BUT only if you are planning on throwing around massive objects all the time. Taylor your service layer to be more responsive to your needs. Don't write a service which requires the whole object when all you need to send is an id (example, it's the difference between sending a whole email back to the server with the 'read' status marked as true, and just calling a 'markAsRead' service with the id of the email). Use paging techniques to break up your dataset, do you really need to fetch all 10k items now? If you are only showing them in 10 item chunks (i.e. in a datagrid) why not fetch them in 10 item chunks (or a few more for visual performance reasons). Well thought out business services can both reduce the amount of traffic you need to send, and allow DTO mapping to be realistic (on both ends of the wire). Gk.

RE: [flexcoders] Binding Model Objects
Jeff,
Yeah, I just jumped all over the DTO part of the discussion. Our DOs
never get near AMF.
We convert everything btw... each record in the DG ends up as an
instance of a DO (which is why the performance of the service layer is
so important).
With DOs, we do make them bindable, but we use custom events to fire the
bindings, and we never ever make the entire object bindable, only the
fields required for the UI. The cheat here is when assembling the DO
from a DTO, use a method that doesn't go through the setters, and then
dispatch the change event once done, that way the binding operations can
be done in a single frame rather than being spread out.
Example (not the best architecture though).
public class fooDO extends EventDispatcher {
private var _bar : String;
public function set bar( b : String ) : void {
if ( _bar != b ) {
_bar = b;
dispatchEvent( fooChanged );
}
}
[Bindable(fooChanged)]
public function get bar() : String {
return _bar;
}
public function assemble( dto : FooDTO ) : void {
_bar = dto.bar;
dispatchEvent( fooChanged );
}
}
Quickly written out, but if all the bindable properties are fired off
fooChanged then the non-bindable DTO can be assembled into a Bindable
DO and cut down on the number of change events being fired. If the
default changeEvent is used, events will fire on each setter used
which is where the presentation is going.
Is that explained badly? Non-bindable DTOs assemble to bindable DOs in a
way that minimizes the amount of event slinging going on...

The renderer is usually a VBox with a lot of HBoxes or GridRows within it. The developer who put these together just used includeInLayout=false for the HBoxes or GridRows that weren't being used. This seems to be a bad idea since there are usually 25-30 renderers on the screen at a time, each with about 10-15 unused layout containers. I am going through and optimizing them now, and started setting the creationPolicy to none on all the items, and where they were previosuly being made visible, I call createComponentsFromDescriptors() on the layout container. This seems to cut rendering time in about half. I am wondering if there might be any unforseen issues I may have using this method. In the code, the textfields(which are the children of the layout containers) are being populated in the very next line after I call the createComponentsFromDescriptors() method. I am a little surprised that the container's children are initialized so quickly to be able to be accessed and take properties. Is this safe to do? Or should I listen for some initialization events before setting any properties on the child components as a failsafe? Thanks in Advance, Adam

RE: [flexcoders] Binding Model Objects
Thanks Gregor,
I think I'm starting to get it. - by having client-side bindable objects,
using custom events, that are generated from DTOs, you minimize the amount of
generic change events being fired.
What about ObjectProxy? Can't similar results be obtained there?

than being spread out.
Example (not the best architecture though).
public class fooDO extends EventDispatcher {
private var _bar : String;
public function set bar( b : String ) : void {
if ( _bar != b ) {
_bar = b;
dispatchEvent( fooChanged );
}
}
[Bindable(fooChanged)]
public function get bar() : String {
return _bar;
}
public function assemble( dto : FooDTO ) : void {
_bar = dto.bar;
dispatchEvent( fooChanged );
}
}
Quickly written out, but if all the bindable properties are fired off
fooChanged then the non-bindable DTO can be assembled into a Bindable DO and
cut down on the number of change events being fired. If the default
changeEvent is used, events will fire on each setter used which is where the
presentation is going.
Is that explained badly? Non-bindable DTOs assemble to bindable DOs in a way
that minimizes the amount of event slinging going on...

Subject: RE: [flexcoders] Binding Model Objects
Gregor,
I'm doing a good bit of what you describe already - like chunking the number of
objects transferred, only transferring what is needed, etc.
My big question based on Sean's preso was making domain objects bindable.
Right now, I am, for the most part. For example, when editing a specific
record in a datagrid, it makes it so much easier to have that object bindable
so I can load it into a form and have the UI reflect that object instance. To
NOT make domain model objects bindable would mean creating a third layer for
binding and loading a non-bindable model object into it. That is a total
headache, but I'd do it, if it really made that much difference. I'm a little
skeptical that a bindable AMF model object is going to fire off a bunch of
events when received by the Flex client.

Re: [flexcoders] Binding Model Objects
This is consistent with the way I've done things. In my case conversion was
necessitated by needing a dirty flag on each record, but I also like it
philosophically.
However, in another portion of the application that I don't own, there is a
large DTO displayed in a table (with user-configurable columns), and I don't
think we can pay the price of conversion without also implementing
pagination/lazy loading.

Jeff,
Yeah, I just jumped all over the DTO part of the discussion. Our DOs never
get near AMF.
We convert everything btw… each record in the DG ends up as an instance of
a DO (which is why the performance of the service layer is so important).
With DOs, we do make them bindable, but we use custom events to fire the
bindings, and we never ever make the entire object bindable, only the fields
required for the UI. The cheat here is when assembling the DO from a DTO,
use a method that doesn’t go through the setters, and then dispatch the
change event once done, that way the binding operations can be done in a
single frame rather than being spread out.
Example (not the best architecture though).
public class fooDO extends EventDispatcher {

RE: [flexcoders] Binding Model Objects
Gregor, Now that I look at it, I see what you're getting at - dynamic classes by nature are going to tax the JIT more. Binding is encouraged by the framework, and in numerous examples, but you don't learn of the potential downside to overuse until months or even years having solved problems a particular way. But this is the nature of the beast, isn't it. Welcome to the world of software development.

[flexcoders] Function Declarations
Good afternoon people,
i just started developping with Flex Builder 3 and I seem to have found some
issues. Let me explain my situation:
I have an application on a mxml file.
In this application i have a AS code file, and I've declared the 'script' block
right at the beggining of the application, with the source property pointing to
the file.
This block is praticaly the first thing on the application.
But the program wouldn't accept when i referenciate some function of the as
file, it would accuse that the function might not exist. I put everything back
on the mxml, and, another day, i put it back on a as file, but this time, it
accepted just fine. Idid not understood or questioned that.
But yesterday, and today, I am having the same problem.
I have the following declarations:
mx:Script source=CCM.as /
mx:Script
![CDATA[
private var _editWindow:generalEdit_window = new generalEdit_window();
]]
/mx:Script
mx:Script source=validation_src.as /
mx:Script source=heights_src.as /
right at the bbeggining of the mxml application,
and after some code I have:
mx:DataGridColumn headerText=Options dataField= width=70
mx:itemRenderer
mx:Component
mx:Image source=assets/imgs/Erro_X_v3.gif
click=removeItem(data.idheight)/
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn
and on the file heights_src.as i have:
private function removeItem(idheight:*):void{
}
I had it as idheight:int, but I changed to * to see if would make any
difference, but nothing happened.
Even with the function declared, the program still accuses:
Severity and Description Path Resource Location Creation Time Id
1180: Call to a possibly undefined method removeItem. CCM/src CCM.mxml line 120
1256660977276 253
Right at that mx:Image... line.
Would anyone here know the reason?
Do you guys see anything wrong?
I really could use some help, since I am somewhat begginner at this...
Thanks for you attention.
Paul.

Re: [flexcoders] basic code behind question
That is correct. Code behinds for components cannot take constructor
arguments, there isn't a mechanism to pass them in.
You will want to pass them in and act on them at some other point in the
component lifecycle. Such as CreationComplete, or Initialize.

[flexcoders] Flex Soap Version Mismatch
I have a problem with soap and flex 3. I have created a webservice through the
import webservice menu in Flex Builder. If I use the service as is I get a
security error because the crossdomain policy on the remote server doesn't
comply. So, instead I am using a php proxy to relay the webservice through my
server and out to the webservice back to the server back to Flex. When I try
to do this I get a SOAP mismatch error coming from the below code.
else if (envNS.uri != SOAPConstants.SOAP_ENVELOPE_URI)
{
throw new Error(SOAP Response Version Mismatch);
}
I went back in and checked the value of envNS.uri and
SOAPConstants.SOAP_ENVELOPE_URI in both the previously described situations
(php proxy and straight security riddled call). In the security riddled call
the two variables match. In the proxy call I get back differing values of
envNS.uri and SOAPConstants.SOAP_ENVELOPE_URI.
Can somebody tell me why the variables are not matching when put through the
php proxy. The php is simple, just curl, so I've pasted it below.
///START PHP SNIPPET
$url = $_GET['url'];
$headers = $_GET['headers'];
$mimeType = $_GET['mimeType'];
//Start the Curl session
$session = curl_init();
// Don't return HTTP headers. Do return the contents of the call
curl_setopt($session, CURLOPT_URL, $url);
curl_setopt($session, CURLOPT_HEADER, ($headers == true) ? true : false);
curl_setopt($session, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($session, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($session, CURLOPT_RETURNTRANSFER, 1);
// Make the call
$response = curl_exec($session);
if ($mimeType != )
{
// The web service returns XML. Set the Content-Type appropriately
header(Content-Type: .$mimeType);
}
echo $response;
curl_close($session);
//END PHP SNIPPET

[flexcoders] States: SetStyle not returning to base state
I have component that functions as a button. It has its own styleName
(menuButton) specified. It has a subcomponent that is a label with its own
styleName (menuButtonLabel) specified.
On rollOver, I set the button to a selected State, using SetStyle to set the
label style:
mx:State name=selectedState
mx:SetStyle target={labelHolder} name=styleName
value=menuButtonLabelSelected /
This correctly sets the label's style per the menuButtonLabelSelected css
values.
However, when I return the button to its base state (currentState = ;), The
label styleName does not get reset to it base menuButtonLabel style, but
instead takes on the parent menuButton style.
Any ideas what I am doing wrong, or suggestions to try? Is my theory correct?

[flexcoders] Re: Function Declarations
Your problem is not with the script tag. What you have would work except that
you are trying to reference the function within an itemRenderer Component.
mx:Component creates its own scope.
You can reference the outer function using outerDocument
click=outerDocument.removeItem(data.idheight)
Even if removeItem() was in the same file, you could not reference it directly
inside the in-line renderer.

and on the file heights_src.as i have:
private function removeItem(idheight:*):void{
}
I had it as idheight:int, but I changed to * to see if would make any
difference, but nothing happened.
Even with the function declared, the program still accuses:
Severity and Description Path Resource Location Creation Time Id
1180: Call to a possibly undefined method removeItem. CCM/src CCM.mxml line
120 1256660977276 253
Right at that mx:Image... line.
Would anyone here know the reason?
Do you guys see anything wrong?
I really could use some help, since I am somewhat begginner at this...
Thanks for you attention.
Paul.
Re: [flexcoders] Using Flex and Vb.Net
You can use Flex for the UI (front-end) and the server side processing using VB.Net. Your VB.Net comes to the picture as web/http services. Although I only began doing the same a few months back, I must say that it's darn pretty good rather than creating a web app using static HTML/ASP.Net only. Angelo From: shot2flow shot2f...@yahoo.com To: flexcoders@yahoogroups.com Sent: Wednesday, 28 October, 2009 0:26:38 Subject: [flexcoders] Using Flex and Vb.Net Has anyone worked with Flex and VB.Net. Please i am interested in the two. I presently use flex and coldfusion, but my company used vb.net so i am wondering how to develop flex apps with vb.net. Thanks
[flexcoders] Re: Flex Soap Version Mismatch
Some more info...
I'm running everything over https
When I create the wsdl code from flex builder wizard, I have to select an
alternative port to connect with the soap1.1 version (on the same screen where
you specify the services you want to connect to). Is it possible that when I
run the php proxy and curl that I somehow lose the correct port to connect to
1.1 and get 1.2 response back. If so, anybody know how I could correct that?

curl_setopt($session, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);

curl_setopt($session, CURLOPT_RETURNTRANSFER, 1);

if ($mimeType != )

[flexcoders] Re: Flex Soap Version Mismatch
I just don't get the overall picture here with this wsdl stuff with flex, so
I've got some more questions and more info. Firstly, I don't have a
services-config.xml file... Do I need one? If so how, where do I create it.
I've seen a bunch of partial info on the subject but nothing really through.
All my stuff is going from https to https, the site is hosted on https and the
service is located on https. Does that matter. I have control over my server
and can put cross-domain files on it. I have a proxy written with curl trying
to relay the call to the service. Do I need to do anything special with that
because I'm am going across https? I guess the port deal selector on the flex
wsdl creation wizard is really a namespace and not a more traditional
communication port number.. Is that correct?
Also, here is my crossdomain file on the root of my server
?xml version=1.0?
!DOCTYPE cross-domain-policy SYSTEM
http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd;
cross-domain-policy
allow-http-request-headers-from domain=* headers=*/
allow-access-from domain=*/
/cross-domain-policy
Does this look good considering https?

This is what I get if I don't pass a rootUrl in to the AbstractWebService
constructor (that's how I use the php proxy)
FaultEvent fault=[RPC Fault faultString=Security error accessing url
faultCode=Channel.Security.Error faultDetail=Destination: DefaultHTTPS]
messageId=null type=fault bubbles=true cancelable=true eventPhase=2]
Which, by the way when I'm working in debug mode on my computer works just fine
until I upload to server.

[flexcoders] Re: Flex Soap Version Mismatch
When instantiating webservice (implements webservice) with this line (no
proxy/destination url, but rootUrl)
this.myService = new ModpayWeb(null,
https://www.mydomain.com/amfphp/services/mpNd.php?url=https%3A%2F%2Fsecure.modpay.com%2Fws%2Fmodpay.asmx%3Fwsdl;);
I get a soap envelop of
http://schemas.xmlsoap.org/wsdl/
which does not match my static const
public static const SOAP_ENVELOPE_URI:String =
http://schemas.xmlsoap.org/soap/envelope/;;
and gives me a soap mismatch error
but when I go directly to the source and don't use the proxy I get back an
envelop of
http://schemas.xmlsoap.org/soap/envelope/
which does match my predefined const
but I get a security error channel DefaultHttps
??

I have comboboxes that might take in different item renderers depending on the situation. The problem I'm facing is showing the selected item on the Combobox label. I want to show it exactly same as to the item showing on the dropdown list. I found somewhere that i should remove the textInput from the Combobox and addChild with a new renderer instance. however I couldnt find a clear solution to this. Any tips on where i should start?
