New Flex WebSite in Cairngorm Framework

Hello All,
I am a newbie to flex. Somehow i learnt flex technology, Cairngorm Framework and ActionSript 3.0. Now i am planning to start flex website.
My architecture,
FLEX[CairnGorm] --> .NET WEB-SERVICES --> MY-SQL 5.0
Now, i had the project set up. My only doubt is, what to use for the flex pages, Module or States or Componets ?????
I know the advantages and disadvantages of each.But i appreciate if any expert guides me ....
Also hwo to change the states of pages in Cairngorm framework..is this done in commad where we vhave the actual business process and get the results
from the web service ?
Please guide me...
Regards,
Ravie

WebOrb allows you to use AMF with .NET. You don't have to stick to web services / XML:

Concerning Modules, States and Components, you must be confused. They are not of the same nature.
- Modules are to break down an application into smaller chunks you can download as needed.
- Components are reusable (usually visual) classes that you can instantiate in MXML or ActionScript and that can themselves be written in MXML or ActionScript
- States represent the states of a given component
You can use all of these in a single project.
In addition, use the history manager and URL fragments for deep linking so users can bookmark you can link directly to a given section of your Flex website.
>>> Also, how do you change the state of pages with the Cairngorm framework ? Is it done in commands where we have the actual business process and get the results from the web service ?
You can use the presentation model pattern. The view state and view logic of each view are located in a corresponding presentation model. When a command calls a service and gets a result, it modifies the application model the presentation model binds to, thereby triggering a change of state in the UI trough data binding.
The view binds to the PM. The PM binds to the application object model. The command updates the latter. Via data binding, both the PM and the view are updated. For example, the view state that is maintained in a PM can correspond to an actual state in the view defined in the <mx:states> tag:

How to achieve modularize in flex using cairngorm framework?

Hi,
I have seen many articles on flex and cairngorm but haven't found enough information on how to achieve modularization in flex using cairngorm framework.
Please let me know any information regarding this.
Thanks in advance.

Hi Sumit,
I am also working similar kind of requirement. In my case I tried to add new tab subtab using personalization , how ever the add new item button is not enable.
So I created new stacklayout and tried to add this to new tab in the existing subtablayout by using co process form request code:
public void processRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
super.processRequest(oapagecontext, oawebbean);
OracleCallableStatement oraclecallablestatement = null;
OracleConnection oracleconnection = (OracleConnection)oapagecontext.getApplicationModule(oawebbean).getOADBTransaction().getJdbcConnection();
try{
oracleconnection.setAutoCommit(true);
oraclecallablestatement = (OracleCallableStatement)oracleconnection.prepareCall("begin GLO_TMPVIJ_PRCV(:1); end;");
oraclecallablestatement.setString(1,"In the custom co process request");
oraclecallablestatement.execute();
}catch(SQLException sqlexception)
throw OAException.wrapperException(sqlexception);
OASubTabLayoutBean subTabLayout =
(OASubTabLayoutBean)oawebbean.findChildRecursive("ApplicationDetsTabLayout");
OASubTabBarBean subtabbar = (OASubTabBarBean)oawebbean.findIndexedChildRecursive("subTabBar");
OALinkBean link = (OALinkBean)oapagecontext.getWebBeanFactory().createWebBean(oapagecontext,
OAWebBeanConstants.LINK_BEAN, null,
"link");
OAStackLayoutBean commentsRN =
(OAStackLayoutBean)oapagecontext.getWebBeanFactory().createWebBean(oapagecontext,
"/xxhr/oracle/apps/irc/candidateManagement/webui/CommentsRn",
"CommentsRn", // always specify name
true); // region created in Oracle9i JDeveloper OA Extension
subTabLayout.addIndexedChild(commentsRN);
subTabLayout.addIndexedChild(link);
in this I am not ale to add the new tab.

Vijay Reddy.

Cairngorm Framework Examples

Iam new to Cairngorm Framework and we need to use this design pattern in our project.
In our project Flex is calling webservice using action script and processing the result returned from webservice call.
Can anybody advise me how i can start using Cairngorm Framework in my project.
Any sample code , links to websites and suggestions would be a great help.
Thank You.

VO in Cairngorm framework?

Hi,
Do you think if I can use object object in Flex to take place
VO in cairngorm application? and I can use struct in cfc as input
argument type.
I try to use VO but I am not lucky to make it work with cfc.
Thanks

How to use generated code from "Import Web Services" with Cairngorm Framework

I recently downloaded Flex Builder 3 beta 2 and tried out the
wizard that lets you import web services. The code that is
auto-generated makes if fairly straight forward to consume web
services using the object types defined in the WSDL. No longer does
the developer need to decode the XML payload! The only problem I am
having is how does you integrate the auto- generated code with the
Cairngorm framework? This seems like a huge question for anyone who
might want to leverage Cairngorm and the auto-generated proxy code
in the same project (like me).
Here are the problems that I see so far.
1) How do you configure the generated service class to work
with the Cairngorm service locator? The service constructor only
accepts a “LCDS destination string” which implies that
you must use Lifecycle data services. Unfortunately, the project I
am trying to retrofit currently uses a WebService and does not use
data services. All I really need to do is change the endpoint URL
(ie from local to a development server). This issue is noted in the
bug https://bugs.adobe.com/jira/browse/FB-8456. What I think is
needed is a way to set the endpointURI in the Services.mxml file.
2) Even if I come up with a hack around #1, I do not receive
a callback to my IResponder even though I register it immediately
after the method call. I can register and listener function within
my business delegate and receive the callback, but my Command
object, which implements IResponder, does not receive the call back
even though it is registered. From what I read in the ASDocs it
should but it doesn’t for me!
These are the issues I have observed in 3 hours of messing
with this. I hope this makes sense. I would love to integrate
auto-generated web service proxies into Cairngorm but I don’t
see a straight forward way without re-architecting Cairngorm. Has
any one else run across this issue? If so, do you have any insights
on how to proceed? Any help is appreciated.

Since I posted this question, I have abandoned the notion of
auto-generated web services and embraced the good old FDS concept
where the RemoteObject meta-tag does all the conversion work for
me. We are now using the Granite DS package and it is working well
for us. I would love to consume web services, but it just isn't
worth the hassle when all you have to do with Granite (and FDS) is
cast your return objects to the proper object type.
BTW, since this posting, I have investigated competing Flex
app frameworks. After my research, I checked out the PureMVC
framework. Wow!! Cairngorm always left me with an uneasy feeling
and I guess I am not alone. Apparently, Cliff Hall felt the same
way. That is why he started the project. I like his approach alot
more than Cairngorm especially since it includes notifications
which allow me to broadcast my own app level events independent
from the AS Event framework. Check out PureMVC. For what it is
worth, it has my humble endorsement. Cliff was even gracious enough
to acknowledge the other Adobe Consulting guys for their work. Good
for you Cliff, I respect that. Check out a better way at

How can I replace the Portal with completely new Flash website?

Can I replace the Portal with completely new Flash website? My customer do not want the JSP UI. Instead, he wants a completely new designed Flash site. Is it possible to do it? How can I deploy a new portal to cover the current one?

If you have a look at some of the code examples which do the equivalent of site maps, you could in theory replace the whole portal desktop with some sort of Flash framework which reads the user's role structure at run time.
I think it is useful to remember that the SAP portal is primarily a business application launchpad. It does that very well. Trying to make it into a Flash launchpad will be challenging.

Incompatible signature after creating a new Flex mobile project in Flashbuilder 4.6

When I create a new flex mobile project and try to build it right away it gives me this error
1144: Interface method initialize in namespace mx.core:IUIComponent is implemented with an incompatible signature in class utest.
I have tried reinstalling Flash Builder and even upgraded from 4.5 to 4.6 to try and resolve this problem.
I have also tried using different versions of the Adobe Air sdk (I'm currently using Air 3.4).
Here is the projects mxml file, if that helps although it doesnt have anything but the generated code.
utest.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:ViewNavigatorApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                            xmlns:s="library://ns.adobe.com/flex/spark"
                            firstView="views.utestHomeView" applicationDPI="160">
    <fx:Declarations>

    </fx:Declarations>
</s:View>
Also I am running Flash Builder 4.6 on Windows 7 32-bit
Thanks in advance for the help
Edit:
I have now tried the flash builder 4.7 trial and even 4.6 on a different machine, both were clean installs, and I have found that when i create a new project it does compile
until I get an error, and this can be any error, then after I fix that error it gives me the same error as before
1144: Interface method initialize in namespace mx.core:IUIComponent is implemented with an incompatible signature in class utest.

Hi Gsaison,
Do you have any progress on these issues? Im working on the same solution right now (SWV + GoogleMaps JS v3 ) I've got some weird issue when i try to spawn a StageWebView inside a View on IOS, it appears inside a scroller and is not open for finger interaction anymore. I use the eskimo framework, but then again, nothing fancy going on there for the rest. I've tried all of the the stage.stageScaleMode options but non of them work. Got any help?
Kind regards,
Roy

Help with project/folder setup for new flex project??

Hello all,
I need help deciding how to set up my projects for a new flex application we're developing.
We have an in-house custom java/jsp "framework". This framework has JSP pages for administering applications that are built using this framework. One part of the framework generates all java base and model objects from our database tables to be used in the new application.
The new application will have a back-office part (Adobe AIR) and a web facing part (Adobe Flex). Both the AIR and Flex parts of the application need to access the java model objects via AS3 classes (I believe I'll do this using remoteobject).
My questions are as follows:
After I create the base and model AS3 classes that remoteobject with the java classes can I put these in a common library project so both my AIR and Flex app can access common AS3 code. I feel I should do this to keep from duplicating code by copying the AS3 classes in both my AIR and Flex projects. Can you give my any examples or links to information on how to do this??
I plan to also create a common java project for all base and model objects generated from my db tables so that the common library project with AS3 classes could remoteobject interface with the java classes in the java project. I would like to keep all of my business logic in the java model classes. Does this seem appropriate for the projects/setup listed above?
Here are the projects I think I need in Flex Builder.
FlexWebApp
AIRBackOfficeApp
JavaApp - Common
AS3FlexLibraryApp - Common
The FlexWebApp and AIRBackOfficeApp will reference the AS3FlexLibraryApp and the AS3FlexLibraryApp will remoteobject to the java classes in JavaApp.
Any help or direction with this is greatly appreciated.
Thanks,
Whitney

Not able to run a program to extract news from news channel websites.

Let me start with stating the fact that I am a super greenhorn, so please be ultra elaborate with the answers .
This is my code, I copied it from Mr. Alvin Alexander (http://alvinalexander.com/java/edu/pj/pj010011?). I am trying to use it to extract news from news channel websites.
I used the following URLs:
1.http://in.reuters.com/
2.http://timesofindia.indiatimes.com/
3.http://www.hindustantimes.com/
// JavaGetUrl.java: //
// A Java program that demonstrates a procedure that can be //
// used to download the contents of a specified URL. //
// Code created by Developer's Daily //
// http://www.DevDaily.com //
import java.io.*;
import java.net.*;
public class JavaGetUrl {
public static void main (String[] args) {
// Step 1: Start creating a few objects we'll need.
URL u;
InputStream is = null;
DataInputStream dis;
String s;
try {
// Step 2: Create the URL. //
// Note: Put your real URL here, or better yet, read it as a //
// command-line arg, or read it from a file. //
u = new URL("http://200.210.220.1:8080/index.html");
// Step 3: Open an input stream from the url. //
is = u.openStream(); // throws an IOException
// Step 4: //
// Convert the InputStream to a buffered DataInputStream. //
// Buffering the stream makes the reading faster; the //
// readLine() method of the DataInputStream makes the reading //
// easier. //
dis = new DataInputStream(new BufferedInputStream(is));
// Step 5: //
// Now just read each record of the input stream, and print //
// it out. Note that it's assumed that this problem is run //
// from a command-line, not from an application or applet. //
while ((s = dis.readLine()) != null) {
System.out.println(s);
} catch (MalformedURLException mue) {
System.out.println("Ouch - a MalformedURLException happened.");
mue.printStackTrace();
System.exit(1);
} catch (IOException ioe) {
System.out.println("Oops- an IOException happened.");
ioe.printStackTrace();
System.exit(1);
} finally {
// Step 6: Close the InputStream //
try {
is.close();
} catch (IOException ioe) {
// just going to ignore this one
} // end of 'finally' clause
} // end of main
} // end of class definition
This is the error i am getting, every time I run it on Eclipse:
Oops- an IOException happened.

Also, when I try a local server URL, the output screen goes blank, which I guess is due to lack of Text on the local URL. So, the little research that I did, made me believe that the code not running on external server was due to firewall on the server side. Please help me run it. Also : I work on a proxy network.( if that has something to do with this).
P.S : Advanced gratitude for any assistance.

any decently secured server would reject such a blatant attempt to steal its content.

Not able to create a new Flex project in Eclipse

I am trying to use Flex Builder 3 eclipse plug-in for
development. But while creating a new Flex project in eclipse, I'm
getting the following error:
Template template.jst.web has not bee defined.
I am using Eclipse 3.3, and have installed the latest WTP
updates. Can someone point out what I'm missing here?
Thanks!

Hi clsung,
Do you get this error on every Flex Project you are trying to
create or just on Java/J2EE projects? Flex Builder beta doesn't
support WTP 2.0 but this shouldn't affect the other kind of
projects.

New flex field in "Gender and Marital Status"

Hi Experts,
Please Let me Know whether we would be able to add New Flex Field in "Gender and Marital Status" in Manage Person Page,.
Thanks&Regards
Prasanna Kesavan

It sounds like you are trying to add a new value of "Significant Other" to the Marital Status drop down. If that is what you are trying to do, the list is controlled through the MAR_STATUS lookup. That Lookup is extensible so you can add new values if you like.
To update the Lookup, navigate to Setup and Maintenance and query the Manage Common Lookups task.
Then query the Lookup Type = MAR_STATUS
From there you will be able to see all of the values available for different countries.
If the options are greyed out, then you will not be able to alter them because they are delivered with the product.
However, you have the option to add new values of your own here.
If you only want to see the value for particular countries, you can add a value in the "Tag" column with the Country Code where the value should be visible (i.e. if the code is only applicable in the US then you would add "+US" in the tags, if the code is applicable everywhere except the US then you could add the tag "-US").
Hope that is helpful,
Karla

FLEX Builder Pro 3 New Flex Project cannot configure J2EE

I have FLEX Builder Pro 3 installed on a Windows XP machine. LiveCycle Data Services is installed (with Tomcat) on a Linux RHEL 5 machine. When trying to create a new FLEX project and configuring a J2EE server am very confused on what to put in Root Folder and Root URL. I have tried various paths on the Root Folder (with a drive mapped through windows and also with just using the servername) and keep getting the error message:
Invalid root. The WEB-INF/flex folder must contain either flex-config.xml or services-config.xml.
I've located the flex-confing file in the tomcat5\webapps\ROOT\WEB-INF directory, but still get the error.
Please any help would be greatly appreciated.

Are your new classes referenced from the old code? Mxmlc employs a questionable form of "as-needed" linking, so classes that are not referenced from the main application are not even compiled. This referencing requirement is recursive; that is, any classes that are to be included have to be referenced from the main application, or from classes referenced by the main application, or from classes referenced by classes referenced by the main application, and so on. But if your new classes are not referenced at all from the old code, they will be ignored.

Help Configuring PHP Server with new Flex project.

Hi,
I'm curious if someone can help me with a frustrating problem.
While creating a new flex project, I can't seem to validate the configuration of the php server. I keep getting the message: "Cannot access the web server. The server may not be running, or the web root folder or root URL may be invalid."
I'm running MySQL, PHP and Apache 2.2. These program have worked indepentally without flex, so I know the program isn't with the install of the stack.
For my web root I entered: "C:\Program Files\Apache Software Foundation\Apache2.2\htdocs" the location where I installed Apache
And for root url I'm using "http://localhost"
The other wierd part of this is that even though Flex would not validate this connection, I went ahead and started the project anyway and made a succesful connection to mysql, obviously though when I tried to launch the project it couldn't connect to the server.
Any suggestions would be much appreciated because flex is pretty much useless to me unless I can figure out how to connect with php and mysql.
