[Discussion]Great doubt in to use Flex you can help us
Hi to the whole community, we are appraising a project of porting, or rather from a system of back-end ibm os/400 we would like to develop an architecture j2ee with a prestation layer in flex. We don't know very well the world macromedia (Flash/Flex/ActionScript), except some demos to know the potentialities of Flex. Then ours great doubt is if we will go to use Swing (we have experience in this scenario) or a new technology as Flex. Have we understood that Flex as ui forms, is unbeatable as beauty and simplicity but the problem that it rises us it is for example possible to create etc an order client or an invoice??? We have seen that the back-end to call is very easy and thanks to the protocol AMF the performances are good, but it are possible to manage the classical events of a classical application, or rather we make an example: in a hypothetical forms/flex orders clients it is possible to manage events type to stop a TextField until the consumer not click on the edit button? Does Delete/Insert command type you/they should polish up the whole forms? To manage dynamic masks in base to the role of the consumer, without having to write 1000 of forms? To manage the internazionalization? Sync ui flex with j2ee db2/lock...? To allow to a consumer that is found in the mask of the orders to be able to pass to another mask without losing the values written in precedence? In short according to you flex and mature for a complex and true application? To our notice it seems that for tender sync the back-end is hard-working, but in a real scenery for applications of this type they are characteristic least to implement; but according to You? What we have asked both possible with Flex but the complexity? Then concluding I think that Flex as graphic quality cannot be put in discussion but as binding with the back-end we are a little worried and we ask help, please, to Your experience. If you can give there some suggestions on some point, or you have some links to also examine of the of code, there would be any thankful. We have also read the book of Flex but a lot of business logic you/he/she is written in Action Script, but for us it will be everything managed in j2ee. Hoping in one great share of yours, and excusing us for our very bad English, we wish you good job. Devis Italy

Re: [flexcoders] [Discussion]Great doubt in to use Flex you can help us
Thank's for your replay, premised that we are still poor in Flex/ActionScript, we agree with you that you can build bad applications in Flex, just as easily as you can build good applications in Flex, the only great problem is as sync flex/ui with our back-end, in our j2ee side we are using in convinced way the designs pattern. While in the swing the iteration between the gui/enduser and the business logic it's consolidated in our team with Flex/ActionScript we find us lost, we hope both normal. In synthesis we have understood that flex him you are using with success, from what I see in the cases of study of your site. the only thing that we are still perplexed is whether to find material to be studied for seeing whether to give to a forms/Flex a similar interaction to a desktop apps, we wish build webapplication like dsktop apps, then to take the advantages of a desktop app and to insert them in a RIA/Flex/webapp. According to you we can find some material or do we have to arm us of patience and does to find one solution of ours or a Flex design pattern exist??? Best, Devis Sorry what means : 1)See you on the dark side. () 2)cuts the mustard please... Steven Webster ha scritto: Devis, A very short answer to your question from me; to put this into perspective, we are a J2EE consultancy that have spent far too much of our past adult lives worrying about IBM Mainframes, CICS Mainframes, Message Queues, Transactional Database development, legacy hardware integration, propagating security credentials across application tiers (Web, Servlet, EJB Tier, etc) and all the other enterprise-class problems you outlined. Furthermore, we've also built thin-client (JSP and all manner of home-brew variants before JSP 0.9 was even a twinkle in Sun's eyes) applications, rich-client applications (from desktop apps built with Mainwin in Java, to rich-client applets (yuk!) built with Java, to Swing/AWT applications sitting atop mainframes and appservers, to Flash RIA and now to Flex). So, I think in many ways, we've came to Flex with all the same fears, concerns, problems, experiences, pains and hesitancies that you have right now. For all the use-cases you outline in your post, then Flex absolutely cuts the mustard -- there's nothing you have said you want to be able to do, that I'd be concerned about doing. I'll caveat this however, by saying you can build bad applications in Flex, just as easily as you can build good applications in Flex. You're going to have to pay a lot of attention to all the best-practices that you're already paying to attention in the Swing/J2EE apps that you're building right now, you're going to have to assume responsibility for technical archticture, for software engineering, and for all the other age-old disciplines that make the difference between a good piece of software and a bad one. But ... and this is the sugar coated good news for you; the choice to embrace Flex as a technology is not going to impose limitation on you as I perceive you think it might, it's simply going to empower you to do things better, all things being equal. We're working with a good number of enterprise organisations like your own who are fitting Flex into existing J2EE workflows and developments, and the concerns you express, are the concerns that I'd expect you to express - and the fact that you are expressing them means I know you can be successful with Flex. Just as they are doing some wonderful things with Flex, so I'm sure you can too. Flex is a presentation server that has been built from the ground up to be familiar to the workflow that a J2EE developer works with, and to fit within existing J2EE infrastructure. Not just J2EE, but there's a fair leaning in that direction right now. I don't doubt for a second that it can fit within your infrastructure, fit within your workflow and deliver on your expectations. If you have any further questions, please don't hesitate to ask.

While in the swing the iteration between the gui/enduser and the business logic it's consolidated in our team with Flex/ActionScript we find us lost, we hope both normal. Have you looked at Cairngorm ? The prime motivation for Cairngorm, was to allow us to bring our experience of working with the Core J2EE Design Patterns (like many J2EE consultancies, prior to Struts gaining wide adoption, we implemented our own framework architecture upon the appropriate J2EE Patterns) to RIA development. I think if you can understand how to architect an application with Cairngorm, you are going to very quickly learn how easy it is to not only hook up a Flex UI to a J2EE backend, but how *familiar* it is, using ServiceLocator, BusinessDelegate and Value Objects/Data Transfer Objects. You don't *need* Cairngorm to build well-architected Flex applications - it would be arrogant to assume so - but if your comfort zone is J2EE, then I think this is an essential starting place to answer some of your questions. You can download the 0.9 release here: http://www.richinternetapps.com/archives/94.html which includes a sample application that hits your J2EE application (with a MySQL backend) and shows how to transfer data back and forth between Flex and Java. Sounds like you guys have J2EE best-practices coming out your ears, so this is going to be a Eureka moment for you. In synthesis we have understood that flex him you are using with success, from what I see in the cases of study of your site. the only thing that we are still perplexed is whether to find material to be studied for seeing whether to give to a forms/Flex a similar interaction to a desktop apps, we wish build webapplication like dsktop apps, then to take the advantages of a desktop app and to insert them in a RIA/Flex/webapp. We recommend our clients to identify a small piece of functionality that is representative of a typical problem, and in going from end-to-end through your enterprise application architecture tiers, touches all the necessary systems. So - if you were building a real-time trading dashboard for instance, you may choose to pick some functionality that listens to a JMS topic, and build a Flex UI that polls for changes to the topic, fetching data when appropriate and plotting it in a simple bar-chart. I'd then recommend that using a technical architecture (such as Cairngorm) to see how you can build that single use-case of functionality. So, rather than worry about the breadth of Flex, focus on driving a spike through an end-to-end solution. This voyage of discovery will allow you to answer yourself, many of the questions you're asking here, I believe. According to you we can find some material or do we have to arm us of patience and does to find one solution of ours or a Flex design pattern exist??? Go and download the sample chapter at: http://www.richinternetapps.com/archives/51.html This is everything a J2EE developer needs to know about working with Flex and Java together; this chapter first appeared at www.theserverside.com Take a look at the sample application with Cairngorm.

RE: [flexcoders] Rotate Label???
In order to rotate a label, textinput or textarea, you need to embed the
font used in these components.
e.g.
mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml; width=425
height=400
mx:Style
@font-face { fontFamily:myfont;
src:url(file:///c:/windows/fonts/Arial.TTF); }
/mx:Style
mx:Label fontFamily=myfont id=out text=Result _rotation=90/
/mx:Application
This code embeds Arial.ttf in windows/fonts directory.
Look at following livedocs page for more details:

This is code in .NET
With .NET, it's quite common for the page-technology to embed SQL
connection information. This isn't a failing of .NET as such (as
there are good practices with ADO.NET and the Microsoft Enterprise
Patterns that can be followed) but is a common 2-tier solution that we
see people implementing, especially from an ASP.NET / VB.NET
background.
Flex does not offer explicit support for SQL; it is a presentation
tier solution, that assumes that any business logic will be performed
on the server-side of the wire. So - I would expect you to have some
.NET code (VB.NET, C#, etc) that uses the ADO.NET libraries to perform
any SQL queries that you wish to perform, and that this code reside on
your server. You will then expose that business tier logic to Flex
(currently) through a WebService interface - if you are using C# for
instance, this is a very simple thing to do using metadata tags on the
class that encapsulates your data access.
Once you have defined a service on the server, Flex can then use the
WebService tag to invoke that service; rather than build up a SQL
query on the client (which is a *very* bad, though frustratingly
common practice) you would instead pass the relevant data (such as
tipo_mant_id) as an argument in a WebService call, such as
agregaDetalleMantencionComputador(),
and receive the results back from Flex.
Once you have that n-tier architecture in place (Flex is a replacement
for the presentation tier *only*) then how to invoke web services on
the server, and how to handle the results that you get back, etc, will
all be much clearer to you from the documentation and (shameless plug)
books that are out there.
So I'm afraid I'd be tempted to suggest that if you want to embrace
Flex as a presentation-tier solution, abandon all hopes of 2-tier
(database code from your integration tier intermingled with
presentation tier code) architecture, and avoid a run-in with the
best-practice police...
Hope this helps,
Best,
Steven

|___select one___|___code___|___name___|
#9632; 101 name 1
#9632; 102 name 2
#9632; 103 name 3

var selectedData:Array = new Array();

RE: [flexcoders] dynamic vbox icon
It depends if you create your accordion segments dynamically (defined in
external files) or if your segments are already defined in the current mxml
file.
For dynamic segment creation, you would use something like this:
mx:Accordion id=someAccordion initialize=initAccordion() /
mx:Script
import mx.containers.VBox;
function initAccordion() {
someAccordion.createSegment(VBox, vBox1, Some label 1,
DynamicAssetsManager.getInstance().getSymbol('ICON1'));
someAccordion.createSegment(VBox, vBox2, Some label 2,
DynamicAssetsManager.getInstance().getSymbol('ICON2'))
}
/mx:Script
With static segment creation, you would use something like this:
mx:Accordion id=someAccordion initialize=initAccordion()
mx:VBox
!-- Define here the content of the first segment --
/mx:VBox
mx:VBox
!-- Define here the content of the second segment --
/mx:VBox

Objet : RE: [flexcoders] dynamic vbox icon
ok, cool,
the class works, at least, it returns the image I want, but where do I need
to call the methode?
mx:VBox initialize=DynamicAssetsManager.getInstance().getSymbol('ICON1');
doesn't has any result,
how does the class knows where (on which object) to link the icon to.
Thanks for your time!

To be able to get icons dynamically, you can create an DynamicAssetsManager
singleton class.
All the necessary icons must be embedded in it (so I don't know if it solves
your problem).
class DynamicAssetsManager {
[Embed(source=assets/images/someicon1.png)]
public var ICON1:String;
[Embed(source=assets/images/someicon2.png)]
public var ICON2:String;
private static var dynamicAssetsManager ;
public static function getInstance():DynamicAssetsManager {
if (dynamicAssetsManager == undefined) dynamicAssetsManager
= new DynamicAssetsManager();
return dynamicAssetsManager;
}
private function DynamicAssetsManager() {}
public function getSymbol(name:String):String {
if (this[name] == undefined) {
trace(DynamicAssetsManager.getSymbol : + name +
is undefined);
return ;
} else {
return this[name];
}
}
}
Then, you can call this manager from anywhere (usually during view helpers
initialization) to get the icon dynamically :
DynamicAssetsManager.getInstance().getSymbol('ICON1');
...
Hope this helps!

Hi All,
I have a accordion pane with some vboxes as its children.
What I want to do is set the icons on these vboxes dynamically.
But as I understand from the docs, these icons can only be embedded?
So isn't there a way to set the icons dynamic?
Thanks for your time!

Question about error message
I am trying to figure out the preview part of the flex builder software and I am still running in to some bugs. What I have figured out how to do is to get the browser to turn on but when it turns on what I see is instead of the webpage I get a servlet error mesage. It is listing where the file is located on the page but not what I want on the page. Let me explain this further, I am trying to run a test of a simple "Hello World" application just to show that I can do the previewing right. I know Ihave created a testing site because it has not given me a message tio set it up. But what happens is when I select previewing it in the browser whichI use Netscape instead of a label with the words "Hello World" it shows a servlet error message listing the location of the file. Any tips? Also if am not being specific enough I apologize.
RE: [flexcoders] Re: how can I do this in Flex? -- (warning, best -practice police are in the hou
Miguel,
Compare function1 with the one you sent. Notice, that I have
dg.getItemAt(i) instead of dg.getItemAt(i+1) and you can get specific
value from the column by giving the column Name like dg.getItemAt(i).code
When you do dg.getItemAt(i), it returns you the entire row row for that
index. The row is an object containing all the columns you have in the
dataprovider of the datagrid.
===Function 1==
function envia_motivos_fuc(){
var Request:Object = new Object();
var selectedData:Array = new Array();
for(var i=0;idg.length;i++) dg is datagrid´s name
{
if(dg.getItemAt(i).select)
{
Request.para = dg.getItemAt(i).code here i´m specified a
parameter
servicio_datos_motivos.send(Request); that´s webservice
}
}
}
=
One more thing that it'll work if you select only one checkbox in the grid
but if you're doing multiple selections from the checkbox then it'll create
problems since for every single selected checkbox, you're sending single
value to the webservice. It'll make a lot more sense if you populate an
array with all the selected items and send that array to the server.
function envia_motivos_fuc()
{
var Request:Object = new Object();
var selectedData:Array = new Array();
for(var i=0;idg.length;i++) dg is datagrid´s name
{
if(dg.getItemAt(i).select)
{
selectedData.push( dg.getItemAt(i).code );
}
}
Request.para = selectedData here i´m specified a parameter
servicio_datos_motivos.send(Request); that´s webservice
}
This way you send any array with all the selected codes at once, which makes
it easier to manage. Let me know if you have any question.

mmm, i have a question now, how can i get only one column of a row i need to
send it how a parameter, but no all row, only a column
for example
|___select one___|___code___|___name___|
#9632; 101 name 1
#9632; 102 name 2
#9632; 103 name 3
supposing that I select the second row, I want to take code only, that is to
say, 102, and this value I want to send it as parameter through an aspx
file across a webservice (which is already done)
my another problem is I do not know if the function to extract the value is
realized well
that´s code:
function envia_motivos_fuc(){
var Request:Object = new Object();
var selectedData:Array = new Array();
for(var i=0;idg.length;i++) dg is datagrid´s name
{
if(dg.getItemAt(i+1).select)
{
Request.para = dg.getItemAt(i).rowIndex(i+1) here i´m
specified a parameter
servicio_datos_motivos.send(Request); that´s webservice
}
}
}
thanks in advance for all help

Miguel,
If I'm right about your question then here's the solution.
The datagrid has 4 columns. One of them has checkboxes in it.
Datagrid = myData
Column1 = select (with checkboxes)
Column2 = name
Column3 = age
Column4 = city
Var selectedData = new Array();
For ( var i = 0; i myData.length; i++ ) {
if ( myData.getItemAt(i).select )
{
selectedData.push( myData.getItemAt(i) );
}
}
selectedData array will now hold all the items from the datagrid
where the
checkbox is selected. To get other columnvalues you can simply
say:
Name = selectedData[0].name;
Age = selectedData[0].age;
Please let me know if that's what you wanted.
Thanks

How to hide/disable the divider bar?
Hi, Has anyone found a way to hide/disable the divider barin a DividedBox? I've tried to play with verticalGap,dividerAffordance and dividerWidth without success. I don't want to use the destroy children method, just to enable/disable the divider bar. The most logical way I've found is to change the verticalGap value (set to 0 to hide the divider) but it does not work dynamically, only when set in mxml. When changingthe verticalGap value during runtime, what method must calledto redraw/resize the DividedBox? Benoit Hediard
Re: [flexcoders] [Discussion]Great doubt in to use Flex you can help us
Thank's for your link and your Cairngorm we are studying the code, only one thing Steve, if you can you to point out away us the straight line please. Today web build a simple registry customer with our j2ee and flex as presentation layer. We have used amf protocol, it's great for us. Considering that flex returns us an array of objects pojo, is it correct to use an autoincrement (simple integer++ or integer--) client side, for it flows the array? or is it a wrong practice about you? Our var integer++/integer--, we use her/it to give the effect Next/Prior/Last/First However considering that all the TextFields are tied up to the model which is in turn connected to the back end, when a consumer click new customer it's correct to clean all the TextFields in this way name.text = ... , according to me it is a wrong approach, but I don't see any other solution in this moment Excuse if I have set you questions source direct . Thank's a good work. Best Devis Italy

htmlText and styles

Re: Subclass method signatures *must* match superclass methods?
Hey Jester, thanks for the response and the workaround, that seems like the only way to get around this problem... I'm not sure composition is really an adequate replacement for inheritance though. Hasn't anyone else run into this? Isn't this a major show-stopper for any real OO application? Is there any logical way to justify this behavior? Does anyone else use Design Patterns in their development? (I'm talking about the Gang of Four stuff, not just semi-macromedia-MVC) Anyone? lb.
