[flexcoders] Re: Changes not detected in index.template.html
I'm running into the same issue getting http://www.deitte.com/archives/2006/08/finally_updated.htm to work under an FDS compile on load situation and haven't had any success either. What bothers me to a fair extent is that this solution (iFrame to render HTML proper since Flex / Flash uses such a lobotomized rendering engine) nullifies one of the main selling points of Flex that it doesn't require javascript to function completely. If the user turns off JS, AJAX is hosed. http://weblogs.macromedia.com/mesh/archives/2006/11/update_on_apoll.html gives me hope that there will be a way around that in the future, but it's pressing a larger client dependency down than just the Flash Player. Will let you know if I come up with anything, but from what I can tell because it's calling the .mxml directly, the index.template.html never creates the pure .html file which your .swf is relying on to handle the JS. --- In flexcoders@yahoogroups.com, Oliver Merk [EMAIL PROTECTED] wrote: I have a project that compiles on the server.

3) Why exactly are u looking to do?
-Have one event type 'task' that handles multiple usages
-Event usages:
-Display all (update arrayCollection)
-Display one in detail (update instance of a VO)
-Add task (add instance of VO to the arrayCollection)
-Edit task (update database for instance of VO)
-Delete task (remove instance of VO from db and arrayCollection)
-Try to understand if one command can be written well to handle these
situations, or if it is better to have a command for each scenario
which all tie in to the same event type
Below is some of the pieces of code I have for the 'generic command'
approach that might help for discussion.
//TaskEvent.as
package com.events {
import com.adobe.cairngorm.control.CairngormEvent;
import com.vo.PersonVO;
import com.vo.TaskVO;
public class TaskEvent extends CairngormEvent {

public static var TASK_EDIT:String = TaskEdit;
public static var TASK_DELETE:String = TaskDelete;
public var User:PersonVO;
public var Task_Update:TaskVO;
public function TaskEvent(p_type:String, p_User:PersonVO,
p_Update:TaskVO) {
super(p_type, false, true);
User = p_User;
Task_Update = p_Update;
}
}
}
package com.commands

import mx.rpc.events.ResultEvent;
import mx.rpc.events.FaultEvent;
import mx.utils.ArrayUtil;
import mx.collections.ArrayCollection;
public class TaskCommand implements Command, Responder {
public function execute(p_event:CairngormEvent):void {
switch(p_event.type) {
case TaskEvent.TASK_ADD:
TaskAdd(TaskEvent(p_event).User,
TaskEvent(p_event).Details);
break;
case TaskEvent.TASK_DELETE:
TaskDelete(TaskEvent(p_event).User,
TaskEvent(p_event).Details);
break;
}
}
//Skipped the actual content of TaskAdd / TaskDelete functions
}
Tom's reply leads me to believe there is a way to do the equivelent -
from my coding example - of having a TaskAdd_onResult,
TaskDelete_onResult and TaskAdd_onFault, TaskDelete_onFault within the
same command rather than having to separate out. But how is not quite
clear to me.

[flexcoders] Cairngorm / MVC Best Practice
It's Thursday afternoon, which means my bi-weekly question everything I've just coded and contemplate serious internal changes on the project. This week the insanity relates to Cairngorm or perhaps Model View Controller design pattern in general, and the best practices of it's implementation. Short Questions: 1) How do you break up your commands / delegates? 2) Is there a way - similar to how a delegate can have a series of functionname_onResult, functionname_onFault - that you can have one command deal with multiple onResult scenarios? 3) Are there any examples out there which deal with these situations specifically? My googles have not lead to good details, but perhaps I'm just querying for the wrong terminology at this point 4) If you're delegate(s) are so simplistic to just act as a gateway, what would a sample look like where you eliminte it? Example Context: You have a screen (view) in which a user can display a list of tasks, select one to display, select one to edit, select one to delete, or add a new one. You'll also have a host of other functions with similar scope (Add staff, Add materials, etc) for arguments sake. Long Thoughts: My initial thoughts built up from Jesse's Amazon Web Service example -Create one custom event (Task) that has a sub-event type for each activity (list, display, add, edit, delete) as a series of constants defined in the event itself. -The execute function in the command (also a responder) would be a giant switch statement that passes off the different pieces of data from the event to the appropriate function within the command. -Each of these calls a delegate to hit a back-end service to get what is required of it and return the results to the command to update the model and the view responds accordingly. This breaks down when I have more than one function returning results from a delegate because I can only have one 'onResult' function within the command. How to code for the differences of if it was a delete action to return the view back to the list of task state versus an edit action to return to the display state for that updated task. My second intention is to create a specific command for each activity (TaskAddCommand, TaskEditCommand, TaskDeleteCommand) and keep the event as described above. But is doing the following in the controller adviseable: addCommand(TaskEvent.ADDTASK, TaskAddCommand); addCommand(TaskEvent.EDITTASK, TaskEditCommand); addCommand(TaskEvent.DELETETASK, TaskDeleteCommand); This is still plagued by the delegate having a huge amount of code just acting as passthru service, but would still be something that coding conflicts would arise on. If you're delegate(s) are so simplistic of just acting as a gateway, what would a sample look like where you eliminte it? Then I could stick with one event type with sub-types, each sub-type references a specific command which does it's own service call / response. Thx, Jamie

To test the new features, I've created a new Service Browser in Flex 2 which allows you to introspect services and test methods on the fly. I need people to test out the new AMF3 support. New/changed features: - $this-methodTable is DEAD. All methods in /services are now considered remotely accessible, unless you set them to protected or private (PHP5) or start the method name with an (_), in which case it will throw an error. If you want to get a description of a method and it's arguments without looking at the class itself, add JavaDoc to the method and you should see it in the new Service Browser. - _authenticate is dead, as a side-effect of the removal of the methodTable. You can secure methods by creating a special function called beforeFilter($methodName) in your class and return false to stop a method from being executed. (the _ and the beforeFilter are the conventions used by CakePHP, so I figured I'd use those instead of rolling my own). - Circular references in AMF0 and AMF3 should now work. Class mapping code has been ported to the AMF3 code also. To use remote class mapping, use registerClassAlias or the [RemoteClass] metadata tag, then read the instructions in advancedsettings.php - Returning a mysql_query will now return either an Array or an ArrayCollection depending on the setting in gateway.php. Other database types are currently unsupported in AMF3 mode (they will be supported as soon as I am sure the AMF3 code is perfect). - You can send ByteArray, ArrayCollection and ObjectProxy instances as arguments to remote methods. You will receive the result as a string, as the inner array and as the inner object, respectively. Currently there is no way to send back these types to Flash, but there will be in the next version. - /browser now brings up the brand spanking new Flex 2-based service browser. You can test methods directly through it. If the method returns an array or arraycollection, the browser will attempt to show it in a datagrid (sweet). Please feel free to modify servicebrowser.mxml (it's very spaghetti-code-ish, but it works). You will need the Adobe corelib to compile (google for the link) Limitations/things to keep in mind: - MySql works but not other databases - You can use a JSON string for arguments in the service browser. However you must wrap object keys in quotes (a limitation of Adobe corelib). - Paged recordsets don't work anymore - Only tested in PHP5. PHP4 might show issues with circular references. - Calling two methods on a remoteObject one after the other (during the same frame) might not work. - Charles and ServiceCapture have some issues with AMF3 handling. You might see strings which seem out of place in your output while it works fine in Flash. I will notify the people involved. You might want to set PRODUCTION_SERVER to true in gateway.php if this is a recurrent problem, in the meantime. - If you need to send to Flash a class and want it to be mapped to a class in a package, you need to add a key to the class called _explicitType with a value of com.mypackage.TheClass and use registerClassAlias or [RemoteClass] as usual ( a limitation of php not supporting packages) All that being said, I need testers. Please download it here: http://5etdemi.com/uploads/amfphp-1.9.alpha.zip (although it states it is amfphp 1.9, there will be no amfphp 1.9. amfphp 2.0 will be amfphp 1.9 + JSON and possibly XML-RPC) If you run into any issues, please either: - Create a minimal test case which shows the reproducible bug, then send it to me. - In gateway.php, uncomment $gateway-logIncomingMessages and logOutgoingMessages, create an in and an out folder and run it again.

[flexcoders] Re: Amfphp with AMF3 support: testers wanted
For the stand-alone basic .mxml I used a copy of the basic example
Renaud gave - with a different URL for the gateway which is located on
a separate server. For the cairngorm / FDS version, here are the
changes I made to the default FDS .xml files
1) In services-config.xml, add the service to the services section
beneath the 4 service include path links add the service:
services
service-include file-path=remoting-config.xml /
service-include file-path=proxy-config.xml /
service-include file-path=messaging-config.xml /
service-include file-path=data-management-config.xml /
service id=amfphp-service
class=flex.messaging.services.RemotingService
messageTypes=flex.messaging.messages.RemotingMessage
destination id=AMFPHPDestination
channels
channel ref=my-amfphp/
/channels
properties
source*/source
/properties
/destination
/service
/services
2) In services-config.xml, Add to the channels section add the
following channel:
channel-definition id=my-amfphp
class=mx.messaging.channels.AMFChannel
endpoint
uri=http://externalURLaddress/amfphp/gateway.php;
class=flex.messaging.endpoints.AMFEndpoint/
/channel-definition
3) Here's the services.mxml remote object:
cairngorm:ServiceLocator
xmlns:cairngorm=com.adobe.cairngorm.business.*
xmlns:mx=http://www.adobe.com/2006/mxml;
mx:RemoteObject
id=roAMFPHPService
destination=AMFPHPDestination
source=AccountService
showBusyCursor=true
mx:method name=checkLogin /
/mx:RemoteObject
/cairngorm:ServiceLocator
4) And the relevant parts of the login delegate which calls:
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.remoting.RemoteObject;
public class LoginDelegate
{
protected var service:RemoteObject;
protected var responder:Responder;
public function LoginDelegate(p_responder:Responder)
{
trace(LoginDelegate::constructor);
responder = p_responder;
service = ServiceLocator.getInstance().getService(AMFPHPDestination)
as RemoteObject;
}
public function CheckLogin():void {
trace(LoginDelegate::CheckLogin function - + p_AttemptedUser.UserID);
service.addEventListener(ResultEvent.RESULT, CheckLogin_onResult);
service.addEventListener(FaultEvent.FAULT, CheckLogin_onFault);
service.checkLogin(UsernameTest, PasswordTest);
}
protected function CheckLogin_onResult(event:ResultEvent):void
{
trace(LoginDelegate::CheckLogin_onResult - Output);
trace(event.result);
responder.onResult(new ResultEvent(ResultEvent.RESULT, false, true,
event.result));
service.removeEventListener(ResultEvent.RESULT, CheckLogin_onResult);
service.removeEventListener(FaultEvent.FAULT, CheckLogin_onFault);
}
And I receive the error Destination 'AMFPHPDestination' must specify
at least one adapter. The php service isn't anything special, just
give username / pass, validate in query to the mySQL DB and return a
specific data element if valid. I know from ServiceCapture and the
other version that I don't have an issue on that side.
Much thanks!

[flexcoders] Database Connectivity - Why so hard?
Does anyone out there have some simplistic examples of incorporating a mySQL database via JDBC with java remote objects to a Flex project, preferably involving FDS? Super++ bonus points if it uses myEclipse too! My googling leads to quite a few things that have bits and pieces but they all incorporate what seems like a lot of overhead (persistence layers like Hibernate, Spring java framework, factories?, etc). I haven't done much of any java programming before so perhaps that green element is adding to the confusion. For example purposes, I have four main cases of functionality I'd like to get my head around: 1) Login - User provides username / password, system provides a unique ID from the database if they are correct, or a null / error code if not. 2) Register - Validated user input passes object to create new user. 3) Display Contacts - Users unique ID passed to method to return complete contact details. 4) Edit Contact Info - User unique ID and updated object data provided to back-end for update. Returns updated contact. I've tried PHP / RPC-XML and can get some functionality out of that, but the java remote object route sounds to be the 'more better' solution and also something a larger % of our company can support once we get past the 'stumbling in the dark RD' phase. I understand a lot of the reasons for OO to decouple functionality to the extent that they do, but when I compare what ASP / PHP / etc of non-RIA applications used to handle with database connectivity right in the code, it seems like there is a heck of a lot of overhead just to accomplish basic tasks.

[flexcoders] Extending Flex Web Services with WS-Security (WSS4J)
WS-Security is not supported by Flex out of the box. Has anyone tackled this, or if not could someone give a high-level view of how they might accomplish this? I can't seem to create a user in the Adobe forums to post it to find out if this might be added in upcoming support point release??? My thoughts on topic: 1) Manual creation of the SOAP Headers will not work because the token has a set expiration time based on timestamp, username, password. Building that logic up in the client app would expose the credentials in the .swf. 2) Using Axis to create a proxy of the true WS-Secure web service might be viable, but seems dumb to create a web service wrapper for an already exposed web service. Plus, my knowledge on the java side is limited and the googles on Eclipse WTP and doing this haven't yielded much more than a headache. 3) With the FDS Plugin facet for Eclipse WTP in theory I can code both java and mxml / as3 into one. If that is the case could I write a component (SecureWS) to extend mx.rpc.soap.WebService to add the WSS4J functionality I'm after. The user / pass parameters would then be stored as part of the named proxy service on FDS. Everything secure and connective. Also something I'd happily share back to the community if I can get some help on how I'd tackle #3. Thx, Jamie [Thread History] In a previous thread that was in danger of being fragmented, Seth Hodgson wrote, WSSAddUsernameToken is part of the WSS4J API that implements the OASIS WS-Security spec. The Flex web service stack on the client doesn't currently support WS-Security out of the box, but WS-Security is based on SOAP headers and you could probably build these manually. Perhaps someone on the list has tackled this and has code to share? It was in response to my question, One of the next web services I'm looking to integrate uses a username / password to create token via WSSAddUsernameToken. Its package is org.apache.ws.security.message. Or so the co-worker who has built connectivity to that out through J2EE tells me. Each client system connects with it's own user / pass combo.

Hello, After a laborious day of uninstalling, re-installing, washing, rinsing, repeating, I finally have my eclipse environment setup with WTP, Java 1.5 and the FDS Plugin Project Peter Martin created. The directory structure seems to make more sense to me, but have raised a couple of questions in my brain - some of which are general Flex / FDS, others are specific to WTP / Tomcat implementation: 1) Without using Peter's FDS Plugin, what is the easiest way to deploy a FDS-enabled project as http://localhost:8080/ or http://localhost:8080/ProjectName/? Every example I've been able to find has it coming out of the flex.war as http://localhost:8080/Flex/ProjectName/ 2) When deploying using FDS compile on server option, how can you configure your server to acknowledge http://localhost:8080/HelloWorld/Main.mxml when http://localhost:8080/HelloWorld/ is accessed? Default .mxml parameters? I'd figure to use the index.htm with presentation similar to the template when using a non-FDS enabled version but unclear where to point the embed items to. 3) FDS Plugin Specific - How *should* one break down their content w.r.t the directory structure provided? I was able to create a simple sample (one event class, one valueobject, two component .mxml views called from the Main.mxml. The only way I was able to get any to work was with everything nested within sub-directories of the WebContent folder. I'd expect I could use the [source_path]user_classes for .swc but it didn't seem to play nice with pure .as files. 4) Same question as #3 but expand your example answer for a Cairngorm-ified project. 5) How to turn all this into a deployable .war or .ear file on a non-development machine? This is more a general java question but figured I'd press my luck like that old tv show and make it a 5 pack o' questions. Thx, Jamie

[flexcoders] Re: role based security vs session based security with a servlet container
Just like Red Two in Star Wars Episode 3 I'll try to Stay on Target Stay on Target and not hijack this thread. Like Hank I'm sometimes feeling the 'newb' factor. One of the next web services I'm looking to integrate uses a username / password to create token via WSSAddUsernameToken. Its package is org.apache.ws.security.message. Or so the co-worker who has built connectivity to that out through J2EE tells me. Each client system connects with it's own user / pass combo. So I believe I should be able to write these into the named proxy web service connection (having issue with that also, put a separate post out for it) on FDS to be secure. Is this the 'J2EE auth' of which you speak? From my googles it seems a fairly standard approach, still lost on the FDS side as to how to integrate such things. Thx, Jamie --- In flexcoders@yahoogroups.com, Seth Hodgson [EMAIL PROTECTED] wrote: Hi Hank, How do you do your logins now against your account database? You're not using general J2EE auth? Role based security in FDS just wraps the existing J2EE auth machinery provided by your app server. You can code your login UI in your Flex app and before any calls or data exchange are permitted through a protected destination authentication will be performed automatically using the credentials you've specified via setCredentials(). You add a security constraint to a destination like so (only users who are members of the 'admin' role are allowed access in this case): destination id=... security security-constraint ref=admins / /security ... /destination The actual authentication is performed via an app server specific login command class. FDS ships with implementations for all supported servers. The command class to use is specified in the security section of the core config file like so: security login-command class=flex.messaging.security.JRunLoginCommand server=JRun/ ... I'd recommend using J2EE auth as opposed to trying to role some other custom approach. When security is involved it's really best to use existing libraries and frameworks that have been heavily tested (J2EE auth for instance), because bugs in this area tend to be more dangerous than bugs in your UI code.

I am using tomcat, and FDS at the moment for remoting. My server side code is obviously in java. A while back, role base security was recommended as the way to implement security. The idea being that if someone did not have the right credentials that they would be prevented from gaining access to the flex app. But my problem with this is that I want to do my authentication UI *in* flex, so I can't prevent people from getting to it before I have had a chance to authenticate. Another problem with the role based stuff is that, as I understand it, roles are maintained by the container. I am not clear how to use my account database (JDBC/Mysql) in this process. What seems easier to me is using sessions, because I can, from any server side function, request the current session of the given user. I can look to see if their session is valid, how long they have been logged on, etc. And using this methodology, I can do login in the flex application, which just sends a login message to the server, the server adds a record to my session record that indicates that I am logged in and when I logged in. This second approach seems like the best approach and the one that gives me the most flexibility. But I am looking for validation regarding my approach here. Am I doing something wrong here? Are there some reasons that the role based security would be better? Any insight from people better versed in security than I am would be greatly appreciated. Hank
[flexcoders] Re: Securing WebServices
I'm running into a few similar issues and curious what the most knowledgeable minds in the group have to say. My understanding at this point says that Cairngorm gives you the service locator and other framework aspects you're seeking, but Flex Data Services is really where the best security solutions lie at this point. Creating a named proxy service destination in FDS that is referenced in your service on the client side. The actual WS URL is not exposed for decompilation risk, and your crossdomain.xml would doubly ensure only the clients / environments you intend access.

I'm trying to solve basic problem of securing access to my webservice on server. I would like to use WS-Security standard, but I'm afraid, there's no way for Flex to send proper request? Simple webservice support in Flex may be not enough in the future... Is this a matter of just writing some additional AS3 classes to extend WS, or the internal flash/flex design? How to solve such problem then? What is your solution? Most obvious one that comes to my mind is to ask server for login, server generates token for client, and client uses his token. But this means that I have to add this token parameter to *every* webservice method. This is not acceptable, as I want (in fact, my customer wants) my services to be free of such things. Authorization should be transparent (but flexible). Then again I could have one big thing, ServiceLocator or something like that, so that every client request will point to this one (so authorization is in one place), with real service name as parameter. This is even harder to implement. So, any ideas? -- | Sebastian Zarzycki / rat[tkin]

[flexcoders] Flex Data Services / Eclipse / Tomcat - Installation Guide
Just when the learning curve felt like it was starting to taper off - likely a minor slope change - I decided to put another 1/2 dozen technologies into the mix just to challenge myself. No really, doing this WILL allow me to do complete end-to-end development from database to middleware to front-end. I thought my learnings might be valuable for a few others out there in Flexcoder land. Don't let this be construed as saying I yet fully comprehend all of what I've managed to do, just that I've hooked up the pieces and it seems to work as a foundation. Several posts on FlexCoders lead me to believe this is a non-obvious process - which I can believe. So if you are interested, I've put together a blog post - http://www.oastler.ca/index.php/flex/20061123_flex-data-services-with-myeclipse-tomcat/ - with the details on what I've managed to do. The post covers the following installations: - Java Dev Kit 1.4.2.13 - The foundation upon which all of my future pain will be built. - Eclipse 3.1.2 - Same version as the Flex IDE was based on is required. - MyEclipse 4.1.1 - Not exactly sure why I need this, but co-workers indicate it will help. - Flex 2 Eclipse Plug-In - Just another installation of Flex 2 as the plugin for Eclipse. - Tomcat 5.5.20 - I thought this came with MyEclipse, only the ability to connect does. - Flex Data Services - Install without the integrated JRun option, as a series of .war files. - Connect the dots, la, la, la.

[flexcoders] Data Driven Method Calls / Change Watcher
Hello, While Occam's Razor may posit that, one should embrace the less complicated formulation, it provides no basis for understanding how to develop that least complicated solution. If you want to call a method of a component when the content of a particular variable that is bound to by a public property within that component changes, use a ChangeWatcher. I've wrote a more detailed blog entry (http://www.oastler.ca/index.php/flex/20061116_data-driven-method-calls-change-watcher/) on the topic for those who are finding it difficult to isolate the component without taking all the spaghetti code with it.

[flexcoders] Manipulating ComboBox.selectedItem issues
I have two combo boxes listening to array collections for their data
providers. When the user selects one entry in the first combo box, the
eventHandler on first combo box change() event will drive what data
should be populated into the array collection for the other combo box.
That part all works fine, code snippets are below.
Everything I've managed to find on using ComboBox.selectedItem has
been a .data or .label or LabelFunction sample and simplistic. What
happens when you have multiple data elements within the entry of an AC
which is dataprovider for a combobox? How come the labelFunction can
return the unique element but I can't access those unique elements for
selectedItem?
mx:ComboBox id=cmbNumber width=100 left=10 top=15
prompt=Select change=PrepareAddress()
dataProvider={Content.acStreetNumbers}/
mx:ComboBox id=cmbStreet width=200 left=118 top=15
prompt=Select labelFunction=drawStreet change=StreetHandler()
dataProvider={Content.acStreetNames}/
private function StreetHandler():void {
Content.acStreetNumbers.removeAll();
for each (var numberRangeXML:XML in SourceXML.Street.(@Name ==
cmbStreet.selectedItem.streetname).NumberRange) {
var i:int;
for (i = int([EMAIL PROTECTED]); i = int([EMAIL PROTECTED]); i =
i + 1) {
Content.acStreetNumbers.addItem(i);
}
}
}
Here's the loop I use to populate the Content.acStreetNames array:
for each (var streetXML:XML in SourceXML.Street) {
var newStreet:Object = new Object();
newStreet.streetlabel = [EMAIL PROTECTED] + + [EMAIL PROTECTED] +
+ [EMAIL PROTECTED];
newStreet.streetname = [EMAIL PROTECTED]();
newStreet.streettype = [EMAIL PROTECTED]();
newStreet.streetdir = [EMAIL PROTECTED]();
Content.acStreetNames.addItem(newStreet);
}
My labelFunction 'drawStreet' picks up the streetlabel variable just
fine. The issue I have is that in another use case for this component,
I want to pre-populate what is displayed in the fields. I can make
cmbStreet.text and cmbNumber.text include the data, but that's a hack
because it isn't truly driven on the underlying data. As a result if
you look into the drop-down for cmbNumber you won't see any entries.
cmbStreet.selectedLabel is read-only so can't be modified for my use.
Modifying cmbStreet.selectedItem with data I know is in the underlying
AC does not seem to trigger the effect.
Modifying cmbStreet.selectedItem.streetname - what I would have
expected to work - gets me a Error #1009: Cannot access a property or
method of a null object reference. on execution.
Even building an entire object to use against selectedItem doesn't work.

[flexcoders] Re: cairngorm: calling a function in a view
I'm sorry, I think you might have just broke my brain :( Or maybe my
grasp on Cairngorm isn't quite as strong as I thought it. The root of
my understanding is based on Jesse (JesterXL)'s example with quite a
few modifications.
I built the parse() method inside the component as it would get into
nested arrays and storing a lot of variables in the global program
that don't have value to do it the other way. Plus, from an OO
perspective I think that is more sound, I can give the SWC to another
developer along with sample XML format to provide to it. Make sense no?
Part of this may be the 'many ways to skin a cat' challenge that
Cairngorm is more a frame on which to hang your code rather than
something that forces you to program in a particular manner.
Any samples of methods on the model and calling components / their
getters / setters from views would be valuable.
Thx,
Jamie

Hi Michelle,
Have a go at using the viewStack container.
create a property:Number in your modelLocator and bind the
selectedIndex property of your viewstack to the property on your model
Locator.
for example
mx:ViewStack
selectedIndex={ModelLocator.getInstance().currentViewIndex}
check out some of the examples on Alex Ulhmanns blog or try

Greetings,
I am having a bit of a problem working out exactly how to navigate
through my application which will be using the Cairngorm 2
architecture.
It currently has the following views: a Login page, a Task List, a
Task and a Finish page. The task list can have any where up to 8
tasks displayed so the user will be switching between Task List and
Task quite often.
The flow between these views will be accessed through button events
(ie, login button, or a start button to start the task etc). There
will be only one View shown to the user at any one time.
I hope that all makes sense.
Anyhoo.
I have read about both the ModelLocator and also
ViewHelper/ViewLocator, and am yet to have that warm and fuzzy moment
where everything just suddenly makes sense, and thus know which is to
be used where.
So my question: What would be the best way to go about handling the
change of Views within this application?
Thanks in advance,

[flexcoders] ItemRenders with Lists / Nested Array Objects
Trying to use a list and ItemRenderer to display output of a
HTTPService called XML file. The issue is that the XML can have
between 1 - 3 'Date' nodes and 1 - 3 'Location' nodes per 'Show'. I
think some sort of repeater / loop is required but my attempts thus
far have not gone well.
The source included does display all the data to the screen, just in a
fugly manner. If someone can offer tips on the itemRepeater process
for lists, most of what I've seen is pointed for dataGrids and I've
been unable to repurpose.

[flexcoders] Re: Why shouldnt you use a specific event type for a command.execute in cairngor
If you have one 'Search' event being broadcast from a view that can search in multiple ways depending on user interaction, perhaps it's searching different resources depending on a radio button perhaps? Then you could use the same broadcast event and evaluate the event data to call different services accordingly. I have one 'Navigate' event that the majority of my views call and pass a constant within that so the command picks that out and updates my model app_State as a result. The main view stack monitors that state. Keeps the views clean of any data manipulation. --- In flexcoders@yahoogroups.com, Rick Schmitty [EMAIL PROTECTED] wrote: Thanks for the replies, appreciate it.

[flexcoders] Learning Cairngorm $0.02
Hello, I've been using Flex for a couple weeks, able to build apps that are a shaky mix of loose / tightly coupled components, but functional all the same. After reading the revered 6-part articles to whet my appetite, I felt I was ready to dig in. The Cairngorm 2 Store demo invoking FDS scared me a little, but I found http://www.jessewarden.com/archives/2006/07/flex_2_webservice.html was an invaluable resource to get started with as it took a less big chunk to try and solve. In a few hours I was able to re-write her webservice example for my HTTPService usage and get a server query to return data. GO ME! I'm still figuring out exactly how to write the question of how to refactor my code from pure Flex to the Cairngormified version, but just wanted to thank people who have answered my questions along the way to get to this point. A resource like this group makes it invaluable in getting up-to-speed without being daunted by the learning curve. If anyone has any tips / suggestions / approaches for refactoring code and main things to be aware of in context of putting it into the right place (controller, VO's, commands, etc) that they could share it would be greatly appreciated.

That does help Tom, just a potentially niave series of questions in follow-up...How does using the proxy FDS service NOT secure the resource?

[flexcoders] Viewstack / Navigator Filtering Best Practice?
Hello,
Looking for a little help as far as best practices for filtering a
navigator (togglebuttonbar, buttonbar) from a viewstack data provider.
Each viewstack is a canvas and I only want to present the selection in
the togglebuttonbar IF the XML node which contains the data for the
canvas exists.
Right now I'm using .addChild and .removeChild on the togglebuttonbar
to control which buttons are displayed. That works the firs time the
app loads, but as the user changes the data source (tied to a textbox
that loads a different xml file) it breaks. I'm thinking there is a
way to control which viewstate elements are displayed from within a
dataprovider, but having issues with that.
Right now, this is the XML event result handler source code:
mx:Script
private function XMLDPHandler(event:ResultEvent):void {
pcXMLDP = new XML(event.result);
bbNavigate.removeAllChildren();
if (pcXMLDP.nodename1.length() 0) {
bbNavigate.addChild(vsNavigate .getChildByName(nodename1));
}

[flexcoders] ComboBox Data Refresh Events
I remember googling somewhere that when you programatically change
combo box data it doesn't trigger the change event. You had to force
an event to fire or on that event call your function or something?
I've built a component that calls an XML source. One combobox
(cmbStreet) is a normal dataprovider list, the second (cmbNumber) uses
the selection from cmbStreet to find the specific node in the XML and
populate based on the relevant attributes.
That part of the code is working, except that I can't seem to clean
all the entries from the array or dropdown list and the function won't
execute on first load. I've tried it in creationComplete but I don't
think the data is loaded to find results at that point.

[flexcoders] Re: ComboBox Data Refresh Events
I temporarily have found the answer of using the valueCommit event
instead of change event as the trigger to update the second comboBox
as it fires on both programmatic and user driven events.

[flexcoders] Re: ArrayCollection returns object Object
I'll take my best attempt.
1) Create the XML variable you will need to map the HTTPService object
data to and create a function that will handle the result call of your
HTTPService call.
mx:Script
![CDATA[
import mx.rpc.events.ResultEvent;
[Bindable]
private var xmldpAddress:XML;
public function LoadXML(evt:Event):void {
xmldpAddress = new XML(evt.target.lastResult);
//Do other result-driven actions here
}
]]
2) In your HTTPService call a function to handle the result event:
mx:HTTPService
id=feedRequest
url = [PATH GOES HERE]
useProxy=false
resultFormat=e4x
result=LoadXML(event)
/
3) So when you trigger the request via feedRequest.send() function
from either the creationComplete part of the application or a button
event, it calls the service, the service calls your result function
and the result function maps that service data object into an XML format.
4) As a result, you can then use dot notation for the XML in any
dataprovider you want.
mx:TextInput x=139 y=143 width=151 id=txtProv
editable=false enabled=false text=[EMAIL PROTECTED]/
At that point, the help page under Programming ActionScript 3.0 Core
ActionScript 3.0 Data Types and Classes Working with XML
Traversing XML Structures should give you all the examples you need to
bind the particular data you're looking for.
Good luck!

[flexcoders] Re: Multiple XML loads?
I had to make a few minor changes to your example to type define the
XML during the function, but otherwise the following WORKS perfectly!
Can also, as a result, use dot notation to access individual elements
/ attributes for comboBoxes within components.
I think the biggest stumbling block for me is to get a complete grasp
on the syntax for different UI elements and XML referencing the proper
elements. Thanks for your help Tracy!

[flexcoders] Re: Multiple XML loads?
God @(#$ do I not so much enjoy being at the bottom of a learning
curve. I can't fathom why putting the .send() into a function which is
called when my button is pushed didn't occur to me but, well, it
didn't. Thank you Tracy!
The second piece that I am now probably doing something very stupid
with is the format of the data and traversing. I haven't used XML a
LOT but I understand the basics of dot notation and have the Flex
'Traversing XML Structures' document printed for reference.
I have been able to populate combobox using the labelField and
dataProvider when the HTTPService is default format (object). However
I am trying to do a lookup in the XML based on the item a user selects
from that combobox and populate a second combobox with details of
children of that selected element. According to documentation if the
HTTPService is set as XML or e4x the following syntax should work in
the Change event:
{XML_PostCode.lastResult.Prov.City.Streets.(@streetname ==
cmbStreet.selectedLabel).NumberRangeLow}
Any attempts I did to 'stub' the HTTPService and use mx:Model or
mx:XML just went very badly for me. Any help would be appreciated.
--- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote:
I am not sure I understand because you don't know which feed to pull at
runtime.
Using AS code you can change the URL of the HTTPService call and invoke
send() at will.
If you need to keep track of which result goes with which send, you can
use the ACT pattern, that allows you to set and retrieve data in an
AsyncToken.

Subject: [flexcoders] Multiple XML loads?
Hi all,
I have one conceptual/programming question right now I'm struggling
with. Say in the blogreader sample app tutorial, you wanted to have
several buttons to read several different RSS or XML feeds. My
attempts using HTTPService have failed because you don't know which
feed to pull at runtime or been able to use a variable in the
HTTPService url. Other attempts have been equally unsuccessful.
Put the code from that tutorial in below for reference.
Any help thanks!

[flexcoders] Multiple XML loads?

I'm about a week into learning Flex, liking a lot of what I'm seeing
for how things have been built. Reminds me of wy back when
Visual Basic was one of the larger tools on the market for front-end

manipulation are right there.
