Create mx:Model statically vs Binding
Title: Create mx:Model statically vs Binding
There are a few other threads about this, and I have never been comfortable with mx:Model so I decided to try to figure it out, but have been unsuccessful. In the small sample app below, I have three datagrids. One uses XML directly, one uses a mx:Model populated statically, and one uses a Model populated by binding the XML.
The direct XML and static model work but I must be missing something basic in the bound model: the DataGrid remains desperately empty. Does anyone see the problem?
TIA,
Tracy

I try to fill a DataGrid from live XML data over

desperately stays empty.
The code is :
mx:HTTPService id=catalogContents

/elements
I know that the Server part is OK, as I am able to
display raw XML
code in the following TextArea:
mx:TextArea

I tried the same, with XML compiled statically,
and it works :
mx:Model id=catalogContentsModel

/
mx:DataGrid id=catalogGrid
dataProvider={catalogContentsModel.result.element}
Help would be greatly needed, I tried many
different combinations of
returned XML without success (like returning
mx:Array/mx:Object
tags, specifying the object attributes as XML
attributes or as XML
elements, nothing work)
Am I *really* an idiot as I seem to be the only
one with this problem.

I have alsohad a
number of problems with support for printing in Flex so I started to look
outside of Flex for a solution. There are probably a number 3rd party
tools that you could try however as I am more comfortable with Java and Flex is
running in a Java app server anyway, I have implemented a solution that works
very well for what I am trying to achieve with iText. iText is a free
Java PDF library and can be found here http://www.lowagie.com/iText/
this has also been ported to .NET if anyone is interested in that.
The way I have
integrated this with Flex is via a Servlet and then using the getURL methodin
Flex. This dynamically creates a pdf every time the servlet is
called. I am able to add headers, footers, images, tables etc, and the
list goes on.
I'm not sure if
this will meet everyone's needs or how support for printing in Flex will
improve with future releases of Flex, however this meets and exceeds the
printing needs of what I need to do. If anyone is interested in a working
example, just let me know and I will post a simpleexample I have
working. If anyone from MM has looked into this or has any comments on
using iText that would be great also.

ViewStack change using separate mxml file
I created a simple mxml applicationthat contains a viewStack. The
stack defaults to the first canvas. This canvas contains a button
that when pushed, changes the stack to the second canvas.
I can get this to work, but what I really want is to put the first
canvas into a second mxml file. The problem that happens is now when
the button is pushed it, the action script doesn't understand the id
of the viewStack. The action script is running on the second mxml
file while the viewStack is in the first mxml file.
The code is:
function loginButtonPressed() {
headerStack.selectedChild = secondCanvas;
}
Flex cannot find headerStack. Is there any way to pass this value
back and forth between the two mxml files?
Thank you so much,
Kim

Re: Integrating with Python
Thanks Manish. Running it as an HTTPService or as a CGI would seem to be the easiest, and I'll give it a try.

I'm not sure if I need to dive into learning how Jython works, or if there is a simpler way I'm missing. If the Jython route is recommended, any links would be great. You could set up your Python modules as services: 1. Web service on Tomcat? 2. Simple CGI script that returns data in XML format. This can be accessed from Flex using HTTPService. You could also try wrapping your Python module into Java using Jython, and then access it using RemoteObject from Flex. I'd go for the service way (HTTPService to keep it simple). Flex can also send data to your Python module via the CGI script in XML format (using HTTP POST?) or as URL parameters (HTTP GET). Manish

RE: [flexcoders] Re: Advanced Printing Question
Hi Tracy,
Not a problem. Yes, my printing needs are quite modest aswell and like I
said in the original email, this solution exceeds my printing needs at the
moment, but offeres the flexibility I need.
Please find attached a simple mxml file as well as a java file which will
need to be compiled.
Add the servlet and servlet mapping to the web.xml file as below:
servlet
servlet-nameSimplePdf/servlet-name
servlet-classsamples.SimplePdf/servlet-class
/servlet
servlet-mapping
servlet-nameSimplePdf/servlet-name
url-pattern/servlet/simplePdf.pdf/url-pattern
/servlet-mapping
You will also need to download the latest iText jar (itext-1.2.jar) and add
this to the lib directory along with servlet.jar
I hope this helps with your printing needs, so enjoy and have fun with the
iText library.
Regards
Mark

Re: [flexcoders] Cairngorm + Flash
Hi Agha, We've used Cairngorm to this point, but we had a good talk with Aral at MXDU comparing the two frameworks and what I've said about ARP is based on this discussion. Try the list Aral posted today in another Flexcoders thread. I need to try out some ARP ideas in a project to sort out my thinking about the two frameworks - but as Steven said ARP provides more guidance around what to do in Flash with the views, as it is originally a Flash framework. Probably the only issue I had with the demo Flex app Aral showed me was the deep purity of the mxml code - as a pragmatic (slothfull? :-) Flex programmer I am rather fond of using a bit more actionscript in my mxml, but then I understand where Aral is coming from - and in Flash I would never put code in my fla. I would be happy to recommend either framework to a client.

Having said that, I'd still like to use Flash for small, not complicated mini apps where Flex is not the option for any reasons (just like Robin said). Ever since I got this taste of Cairngorm with Flex, I find it hard to convince myself to go with Flash without a framework as elegant as Cairngorm. That was my main reason to see if it was possible to use it with Flash. I have installed ARP but didn't really get a chance to look into it.

RE: [flexcoders] Re: ViewStack change using separate mxml file
Certainly. From any script in a Flex application, you can access data from
any component and store it anywhere. You can use relative or absolute
access, as in any hierarchy.
From a script of the parent document, you can access properties of
descendant components by dotting down relative to the parent, using the
ids of the descendants:
someChild1.someTextInput.text = someChild2.someTextInput.text;
This is analogous to a relative path:
cd a\b
In a script of the first child you would do
parentDocument.someChild2.someTextInput.text = someTextInput.text;
because these expressions are evaluated with 'this' being someChild1.
This is analogous to a relative path which goes up a level:
cd ..\a\b
When you write a Script in a component, think of that component as like
the current directory. You can go down or up the hierarchy of nested
components from there.
Note that I said nested components, not nested containers. Flex does NOT
make you dot down through every container inside a component. That would
make your scripts break every time introduced another container to affect
the layout.
By absolute access I mean dotting down from the top of the hierarchy,
which is the Application object. In any script you could do
Application.application.someParent.someChild1.someTextInput.text =
Application.application.someParent.someChild2.someTextInput.text;
This is analogous to
cd c:\a\b
I will save explaining the difference between writing
Application.application
and just
application
for another day. (Hint: They can be different when you have an app which
loads another app.)

Subject: [flexcoders] ViewStack change using separate mxml file
I created a simple mxml applicationthat contains a viewStack.
The
stack defaults to the first canvas. This canvas contains a
button
that when pushed, changes the stack to the second canvas.
I can get this to work, but what I really want is to put the
first
canvas into a second mxml file. The problem that happens is now
when
the button is pushed it, the action script doesn't understand the
id
of the viewStack. The action script is running on the second
mxml
file while the viewStack is in the first mxml file.
The code is:
function loginButtonPressed() {
headerStack.selectedChild = secondCanvas;
}
Flex cannot find headerStack. Is there any way to pass this
value
back and forth between the two mxml files?
Thank you so much,
Kim

Theory and Practice: Mixing AS2.0 in MXML
code - as a pragmatic (slothfull? :-)
Flex programmer I am rather fond of using a bit more actionscript in my mxml,
but then I understand where Aral is coming from - and in Flash I would never
put code in my fla. I would be happy to recommend either framework to a
client.
Not having seen Aral's recommendations, I can't comment
specifically, but I'd also like to pick up the idea of
"no code in MXML" as a "besttheory" rather than
a"best practice".
Separation of content and code is the key driving
principle, imho, as to why when we were building RIA with
Flash, that it was essential not to scatter ActionScript
code around the actual Flash movie itself. So ... we
would advocate that code wasnotscattered around
the timeline, that there was a single layer in the timeline,
with a singleframe, wherea single file
"includes.as" was included in the application, and the bare minimum
of
initialisationcode (perhaps creation of your
controller) was placed on that first frame.
Thereafter, we advocated using the Cairngorm framework,
extracting all business logic in classes, and keeping
these classes in external ActionScript files. Despite
the limitations of the Flash IDE as an RIA development
environment, this allowed us to achieve best-practices of
keeping our content (the FLA) as separate as possible
from the code, in turn promoting reuse, promoting
maintainability, encouraging that code could be versioned
and kept under source control, etc.
Inevitably, some code might find it's way into a component
in the Flash Symbol library; but if this ever were
the case, then it would be code that BELONGED on that
component, and was typicallyresponsible in some
way for the view logic associated with that component - so
some degree of encapsulation was achieved. But
code in the FLA rather than in external ActionScript 2.0
was a bad code smell.
Let's now move to Flex.
Let me first state the obvious; I would not advocate
placing business logic (or lots of it) within
mx:Script
blocks in Flex, if it can be extracted into an external
ActionScript 2.0 class. I would *never* use the
Include functionality in Flex to pull in blocks ofscript,
and where possible, I would always encourage that
external classes, imports, and object creation is
used.
However, let's remind ourselves why we might want to not
have code in our MXML -- not in theory, but
in practice.
Not mix content and code
This is the key one; if we have business logic in our MXML,
we should be refactoring this into external
AS2.0 classes (and unit-testing it). If
you have screeds of business logic in a big mx:Script
block,
then you should be pulling this into external classes - you
are beginning to mix your content and
your code.
Maintainability and Scalability
If we have AS2.0 code in our MXML, does it make our code
harder to maintain ? Not necessarily -- if
the code is directly related to that MXML file, itmay be
the case that encapsulation would encourage
the code to belong as a method on the MXML file. An
example ? Perhaps we have a click handler,
that is going to respond to a button press in our MXML
component; perhaps on pressing a button,
we want to set a status bar message, and then broadcast an
event for the controller ... it makes
sense to have:
public function billPaymentButtonClick() :
Void
{
ViewLocator.getInstance().getView( "statusView"
).setStatusMessage( "Paying Bill..." );
EventBroadcaster.getInstance().broadcastEvent(
EventList.BILL_PAYMENT_REQUEST );
}
and then in our same MXML file:
mx:Button id="payBillButton" label="Pay
Bill" click="billPaymentButtonClick()" /
In this instance, I do not see what is to be gained by
being purist, and extracting the
billPaymentButtonClick() method out of the MXML and into an
external AS2.0 file, JUST to
be able to say it's an external
file. This is a convoluted example, that I don't want to
pick
apart (there are nicer ways of doing it) but it serves a
point I think.
Because MXML are text files, we can still keep these files
under source control, and we
can merge them if more than one person works on them.
More importantly, for maintainability,
I would argue that it's easier for developers to maintain
this source, where the methods
that are unique and specific to the MXML file, areheld
within the MXML file - especially when
they are concerned with view logic, or with dispatching
events so that they can be used
as discrete components without coupling them to anything
else in the architecture.
We're not risking the scalability, maintainability,
performance, clarity or elegance of our
code by mixing MXML and ActionScript 2.0
here.
On clarity; often in the Flex Book, we would placemore
code than we would be comfortable
with in a production project, in the body of the MXML file
... but we did warn about this in
the introduction to the book. Why ? Because we found
that when trying to explain a
concept, the clarity of having the code in the MXML file
RE: [flexcoders] Theory and Practice: Mixing AS2.0 in MXML
After all, a MXML gets compiled into a AS 2.0 class. Most MXML files are
instances of the View (classic View in MVC that is) - so to me it's logic
andvalid to have functionality inside that file that handles and delegates user
interactions.

RE: [flexcoders] Theory and Practice: Mixing AS2.0 in MXML
Personaly I don't like putting code into mxml's too, for me they are just the visual part of the application. I also don't like the idea of having a class somewhere far away from my form wich is called on a (for example) submit button event and then accesses the formfields to check their values. What I do is naming the mxml (class) file like this: classNameVisual.mxml and subclass that file with an .as file called className.as. This way I can instantiate the form as className and have a local reference to the formfields inside my .as file. There I do actions that apply to the form only and use events to communicate with the rest of the application. This approach results in two files vor each view (form, mxml, whaever). The only consern of the .as file is the mxml file. And they are easy to find.

So ... we would advocate that code was not scattered around the timeline, that there was a single layer in the timeline, with a single frame, where a single file includes.as was included in the application, This is definitely one, valid way of doing things -- however the #include method of loading code into Flash projects is the old-school way we were forced to use in the days of AS1. With AS2 and the ability to link classes to movie clips, this method is no longer necessary. It makes sense to keep all code in external classes and link them to your movie clips (forms) when necessary. The code Application form, then, becomes a natural entry point into your application. Natural in the Flash-way of doing things. Does this method of working translate to Flex? Of course -- Flex *is* Flash :) The most striking difference between Flash and Flex (apart form Flex actually having *useful* components that work) is the way you layout your forms: Using MXML instead of an FLA. The fact that Flex is a server product is irrelevant (and completely unnecessary -- it *should* ideally be a client-side tool that outputs SWFs.) In Flex, instead of linking your form classes to an ArpForm or an mx.screens.Form, you link them to mx.containers.Form or mx.core.Application. Migrating an application from Flash to Flex thus becomes simply modifying your forms to handle any component API differences between Flash and Flex and reconstructing your form layouts using MXML (the reverse is also true for migrating a Flex application to Flash.) Any code you have in your FLAs or MXMLs just makes you less flexible and for what? A potential few seconds saved when you are initially writing the code. It has been my experience that actually writing code takes the least amount of time in a project -- debugging, maintaining and scaling an application all take far more time and that's what we must try to reduce. It all comes down to one thing: I like simplicity. The less rules there are the less I have to think. If I know that there's no code in my MXML or FLAs, I don't waste one second of my time searching through them. I know where everything is the moment I look at a new ARP project, even if I've never seen that particular project before. For me, this is more important than saving a few seconds during initial development by adding code to my FLA or MXMLs. Inevitably, some code might find it's way into a component in the Flash Symbol library; but if this ever were the case, then it would be code that BELONGED on that component, and was typically responsible in some way for the view logic associated with that component - so some degree of encapsulation was achieved.

New to Flex and having difficulties with validation
Title: New to Flex and having difficulties with validation
Hello everyone,
I'm new to Flex (started on Monday) and I'm having a lot of difficulties with validation.
Here's the situation:
I have a model in which I load data from an external XML
mx:Model id=edgesmodel source=edges.xml/
Then I use a repeater to put the information on screen:
mx:Form
mx:Repeater id=edgesrepeater dataProvider={edgesmodel.edge} recycleChildren=true
mx:FormItem label={edgesrepeater.currentItem.label} : required=true
mx:TextInput id=edgeinput width=75 text={edgesrepeater.currentItem.value} /
/mx:FormItem
/mx:Repeater
/mx:Form
The user can change the edge value in the textinput field, so I wrote a function which updates the information in themodel (this works fine).
And finally I would like to do validation on the value field of the edgesmodel before I execute the program.
Could someone point out how I can do thisvalidation?
Thanks a lot!
Jeroen.

RE: [flexcoders] Click on button problem
Hi, It seems to be a limitation, however I will verify and file the issues.. Since both buttons are at same place, when you click one button and don't move mouse and other button appears at the same place...Other button doesn't get into over state or doesn't get the focus. So you have to do either of following: - move mouse out of the button area and move mouse back on button then click. - Or do double clicking First click gives the focus to button and second click executes the click handler.. This is more of Flash Player level issue... But as a workaround, you can try adding trackAsMenu=true in Button tag, as shown below.

information formfirst name, last name, address 1, address 2, etc. I also
have 3 fields: phone, fax, and mobile, but I only have the phone field as being
required (visually, anyways, utilizing the required attribute set to true of the
mx:FormItem component, but set to false for fax and mobile). I also have
phone, fax and mobile being monitored by the mx:PhoneNumberValidator components.
But the problem is the form wont submit if the user hasnt entered a fax
or mobile, even though theyre not required but because I have validators on
them. Is there any way to ONLY validate them if the user has entered a
value in their fields and not enforce them as being required even though I dont
have them flagged as being required?
Also, how do I validate
whether a user has selected an option from a drop-down or a radio button
group? I am successfully setting their values to the data model I have set
up but do I use a StringValidator on those values to ensure something has been
checked or is there a better way to do that? I looked at the examples in
Stephen and Alistairs book but some things arent valid in Flex 1.5 anymore and
other things just confuse the heck out of me or dont apply to the type of form
Im trying to build and validate.
Any help on any of
these things would be most amazingly appreciated.

What i do is extending the mxmlclass with an AS class. Then instead of using the mxml i use the AS subclass. If the class is empty, things just work like they did before.

RE: [flexcoders] Number Format issue. I need help.
Your example works fine as long as totalAmt is a number, formatting will work as expected.
My problem has a different context, though:
I have 2 text inputs, both of them are being formatted using the regular NumberFormatted. Im trying to get the numbers out of the 2 text boxes, add them up and format the result. The form is a regular data entry screen; Im retrieving the text input as textInput.text which gives me back the formatted number. So in order to get back a number I use parseFloat(formattedString).
If the number is 0.4 (more than 5 decimals), I get back 4e-5, in scientific notation. Id like to be able to get back 0.4 and to format it properly.
Thanks.

RE: [flexcoders] Number Format issue. I need help.
Show it as string, I mean internally calculate as number then convert number
to string and show in the textfield
I wrote a quick dirty routine, that might help you.There might be a
better way to do, this is what I have done using string operations...
code
function getDecimalString(n:Number):String
{
var s:String = n.toString();
if(n.toString().indexOf(e-)!=-1) {
var arr = n.toString().split(e-);
var v1 = Number(arr[0]);
var v2 = Number(arr[1]);
s = 0.;
var i = 0;
while(i++v2) s+=0;
var s1 = v1.toString();
s+= s1.length1 ? s1.split(.).join() : s1;
}
return s;
}
/code
An example:
DecimalToString.mxml

mx:Application width=800 height=600

var v2 = Number(arr[1]);
s = 0.;
var i = 0;
while(i++v2) s+=0;
var s1 = v1.toString();
s+= s1.length1 ? s1.split(.).join() : s1;
}
return s;
}

{
out_ti.text = getDecimalString(parseFloat(in_ti.text));
}

newbie
Hi members, I am new to Flex coding. I did learn a lot from coenraets web site and also from richinternetapps.com. I do really appreciate them for letting others to see their code and learn from it. I do have couple of issues to resolve. I did try search on Livedocs and other websites for solutions but didn't find any. 1) Can any one programmed hotkeys(keyboard shotcuts) in flex ? for example, instead of using mouse to click on tab of TabNavigator container users can use keyboard shortcuts say Ctrl+T or Alt+T something like this. There will be a problem using Alt as accesskey because Alt key has been used for windows hotkeys. Please help. 2) My user requires that they should be able to zoom a scanned image and then move/drag that image. I did accomplished zooming part but unable to drag the image. Here is the mxml file for your ref. manageSchedule_3.mxml Thanks in advance. Thanks! Hari binRfuAMOkVrx.bin Description: Binary data

Printing issue
Hi, I have to print data from a datagrid with several columns(12). Defining a print job, I intend to modify the default page orientation, to print in horizontal orientation, but it doesn´t work. Any thought?. Thanks in advance. My code: var pj : PrintJob = new PrintJob(); //orientation pj.orientation = landscape; ... pj.send(); Remark that the orientation assigment is done previous to send data to the printer. Isaac Bibás
Error message with data binding
I've created a databinding in a component that works OK, but gives me a
warning.
I have an xml file called sales.xml storing a value this way:
plan
description id=DIRECT
element
nameDescription/name
valueThis is some descriptive text./value
/element
/description
other nodes here
/plan
in the main application file I create a model from this and pass it as a
dataObject to a .mxml component called Description:
mx:Model id=dp1 source=sales.xml/
Description id=sDesc dataObject={dp1.description.element}/
In the component, I define the dataObject var in a script block and execute
the databinding:
mx:Text text={dataObject.value} width=100% height=100%/
This all works fine, except that I get a warning, pointing to the
databinding line: changes in unknown property, value, will not be detected.
Is there a way to avoid this warning, or a more efficient way to do this?

Can't find entry point for Cairngorm
I'm up to speed on Tomcat now and attempting to install Cairngorm. As the docs are rather thin, I'm assuming Cairngorm is an application skeleton with an entry point. The file INSTALL.txt mentions an Index.mxml file that does not appear to be included in the cairngorm zip file. Can someone from iteration::two place shed some light here? Thanks.

That was my initial approach too, but eventualy it was
easier to track bugs and 'mis-references' since i extended the component i was
accessing. Now i get an error when i try to reference a textfield that isnt
there. Another thing that is a pro for this kind of approach, is that the mxml

RE: [flexcoders] fscommand and flex
Why don't u try to use getURL?
U can use it like this:
getURL(javascript:functionName('arg1', 'arg2'));
Internally fscommand is converted to something like:
getURL(fscommand:functionName...), I don't know exactly, but there was
a thread about it on flexcoders a month or so ago.

RE: [flexcoders] fscommand and flex
I think if you're using IE, you have to create a VBScript passthrough
because fscommand will only call a VBScript function. Your original code
worked for me in Firefox but not in IE. (Plus, you might have to watch the
caps of myMovie_DoFSCommand -- the D is capitalized).
Try adding the myMovie_FSCommand passthrough in the jsp page:
%@ taglib uri=FlexTagLib prefix=mm %
html
head
script language=VBScript
Sub myMovie_FSCommand(a1, a2)
call myMovie_DoFSCommand(a1, a2) // Pass the fscommand through.
end sub
/script
script language=javascript
function myMovie_DoFSCommand(arg1,arg2){
alert(fscommand called);
alert(arg1 + arg1);
alert(arg2 + arg2);

RE: [flexcoders] Number Format issue. I need help.

thanks for your example it was very helpfull I added an extra text box and wanted to do some sum between the 2 boxes... very basic stuff...
function setOutput()
{
var value1 : Number = parseFloat(in_ti.text);
var value2 : Number = parseFloat( in_ti2.text ) ;
var total : Number;
total = value1 + value2;
out_ti.text = getDecimalString(total);
// out_ti.text = numberformatter.format( getDecimalString(total) );
}
Well when I add 0.999344032 with 12345678901234.01 the result is: 12345678901235 ( no decimals )
or
0.999344032
+ 111.01 = 111.999 ( only the first 3... ) I would like to see all the decimals...
Can you help me? Am I missing something? Below you can find the modified code.

Page 534.
You need to create an application, your application needs
to create a front controller, you need to register a command
with the front controller, and you need something (a button ?)
that broadcasts the event tied to that command.
There is also a sample application ships with the Cairngorm
ZIP file, in the samples directory - there you will find
Index.mxml that shows you what your MXML entry point should
look like, a com/ directory with all your actionscript code,
and a java/ directory with all your server side code.
Spend some time understanding how that 2 MXML file sample
application has been built, and how it interacts with the
files in the com.iterationtwo.cairngorm.* directory
structure.
In summary, the following code in Index.mxml:
cairngorm:controller
{ com.iterationtwo.demo.control.DemoControl }
/cairngorm:controller
Creates a controller. Login.mxml has this code:
mx:Button label=Login click=doLogin() /
It also (shriek) has some ActionScript 2.0 implementing that method:
public function doLogin()
{
EventBroadcaster.getInstance().broadcastEvent( login );
}
If you then view the source for com/iterationtwo/demo/control/DemoControl.as
you'll see how the login event is tied to the LoginCommand.as file.
You should be able to work the rest out from there.
Good luck,
Steven

var s2 = 12345678901234.95; //it would show as
12345678901234.9
and
var s2 = 12345678901234.96; //it would show as

Hi,
1) Yeah, you can trap the keyboard events using ActionScript. You can use
keyDown event with Key object to find about pressed keys.. See example
code later in the mail.
2) you can use the combination of mouseDown, mouseMove mouseUp event to
make dragging happen. Look at Manish's Google map example, see how he is
dragging...

users can use keyboard shortcuts say Ctrl+T or Alt+T something like this.
There will be a problem using Alt as accesskey because Alt key has been used

RE: [flexcoders] newbie
Hi,
This is an issue that I have also had to
deal with recently.
I had limited success using code similar
to that which you have outlined below. The major problem is that pressing CTRL
+ the majority of keys causes the browser to intercept these key presses and
perform its own actions. Trying ctrl + almost every key on the keyboard
resulted in only getting about 6 or so CTRL + key combinations being made available
to me. Trying ALT + key was even less successful as the flash player just
seemed to loose focus entirely, with the browser menu then being given focus.
Has anybody else had any success with key
board shortcuts? At first glance, it doesnt seem to be possible to
provide logical keyboard navigation on forms with more than a handful of
controls. Of course, tab navigation is still possible.

RE: [flexcoders] Theory and Practice: Mixing AS2.0 in MXML
I was about to say that. It's besicaly like asp.NET where
you have the tag bas view on the html and the code in C# or VB in a code-behind
file. I use jimmy's method using the viewHelper because otherwise you wouldhave
the mxml file a actionscrip class (code-behind) and the viewHelper also if you

of approach, is that the mxml file doesnt have to know wich method to call in
the helper class.

to put such code in the corresponding ViewHelper class, so every view (MXML

below:

Re: [flexcoders] Autocomplete text filed
hi you can store your data in a array and add a text field to a canvas, when your texfield gains focus (or whatever) you can with absolute position show a list underneath the textfield with the items in the array that match your criteria. I´m not sure if this can be achieved without the canvas because of the absolute posisioning, but if you dont want to do all this stuff you only add a editable combobox and add and remove the items that match te criteria and when the combobox gains focus you can show the list.

Remote Object architectural question
Flexcoders, I have 2 Java classes: bean and service. The service class has a save method that takes a bean so it knows what to save. I want to use the Flex RemoteObject data service to call the service's save method and pass it a bean. When I do that, Flex appears to be calling all of the setXXX(arg) methods on the bean, whether I want it to or not. Is this how the Remote Object data service was designed? If so, is there any way of breaking that and forcing (or allowing) Flex to only call certain setXXX(arg) methods on the bean? Thanks, -Will
RE: [flexcoders] Remote Object architectural question
It does so by design (a much requested feature that was added in Flex 1.0), but in order for you to skip the Java Bean like deserialization, you could do the following: 1. Don't send type information using the _remoteClass property (I've never been a fan of this method of object typing) 2. Don't register the AS class using Object.registerClass Without these two bits of information, it should be treated like a normal java.util.Map. With this map, you could do your own bean setter logic. -Original Message- From: wcucsd [mailto:[EMAIL PROTECTED] Sent: Thursday, March 03, 2005 3:25 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Remote Object architectural question Flexcoders, I have 2 Java classes: bean and service.

MXML - ActionScript : where is the code cached?
Hello, In an effort to get a better feel for the mapping from MXML to AS2 I'd like to spend some time staring at the code generated by MXML. Can someone please tell me where it is cached? Thanks. -Douglass Turner
RE: [flexcoders] MXML - ActionScript : where is the code cached?
You keep the generated ActionScript files by setting the
following in the flex-config.xml file:
keep-generated-astrue/keep-generated-as
The generated files should be in the same directories as
the mxml files, with the name {filename}-generated.as.

RE: [flexcoders] Number Format issue. I need help.
Title: Message
http://stz-ida.de/html/oss/js_bigdecimal.html.enhas a _javascript_ implementation of BigDecimal. Perhaps
it could be ported to ActionScript if the licensing is acceptable. But
Macromedia has no connection to this code and can't offer any

Java
offers BigInteger and BigDecimal. It might make sense to avoid doing business
logic on the client and let the server handle the arbitrary-precision decimal
arithmetic. You could send data back and forth as strings.

Hi,
Valy.
There is nothing strange going on here. You would
have exactly the same problem using "double" in
C++.
A Number in the Flash Player uses the
double-precision IEEE 754 standard representation for a binary
floating-point value. (Why? Because this is the representation manipulated
at the machine-code level in today's microprocessors.) It uses 64
bits, 52 of which store the binary digits, 11 store the exponent, and 1
stores the sign. 52 binary digits can store only 15-16 decimal digits.
(Solving 10^n = 2^52 gives n = 15.65).
Furthermore even a decimal number with only a few significant
digits, such as 1.3, can't
be exactly stored as a Number. It might get stored as something like
1.29 or 1.31because many decimal fractions
can't be exactly represented by any finite number of binary digits, and vice
versa.
If your application requires
arbitrary-precision decimal arithmetic rather than fixed-precision binary
arithmetic, you will need to find or write a package that does this. Flex
doesn't offer such a package at this time, but perhaps others on this list
know of such a package written in ActionScript.

the result is: 12345678901235 ( no decimals )
or
0.999344032
