RE: [flexcoders] Front Controller
Hi, Devis. What about manipulating the visibility and height of the fields? I've implemented dynamic screens this way. I did not use mx:Form, just a VBox, set the verticalGap=0, set a fixed height for my fields (30). If a field is not to display I set visible = false and height = 0.

Hi all, Long-time lurker, first-time poster... I wanted to draw your attention to an issue that I'm having with Flex Builder: Basically, the Preview/Run/Debug functionality stops working when you subclass mx.core.Application and/or mx.containers.Form in your applications. Of course this is a perfectly legal thing to do and, actually, the ARP framework will be recommending this as a best practice (among other things,it makes migrating from Flash to Flex child's play.) It also gets around having to mix code into your MXML files -- which is a nasty practice akin to how we used to #include script files in ActionScript 1 in Flash. In any case, this is a fundamental use case and it appears that Flex Builder doesn't currently support it. I posted about this on my blog in more detail, with a barebones sample to demonstrate the bug: http://www.flashant.org/index.php?p=273more=1c=1 I am still holding out hope that there is a way to override this default behavior in Flex Builder to tell it that it's ok to preview a subclass of Application/Form but I haven't been able to find such a way using the Dreamweaver extensibility APIs.

This is a known bug in Flexbuilder that was raisedup on this list when people started trying to build applications using the CairngormApplication tag that we advocated in the 0.9 release of Cairngorm. Currently there is no workaround other that using the mx:Application tag if you want to work in Flexbuilder. Macromedia are aware of the issue - we raised it and it was acknowledged as a bug. It doesn't however mean that people will have to dump lots of code in their MXML files; using the Application tag, developers are still free to create their own ActionScript 2.0 classes, and if you don't want to import them and instantiate them within mx:Script blocks, you can instantiate them "MXML-fashion" using namespace declarations.

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.

Problem : when starting the webcam with the Flash debug player 7.0.35.21 (the one coming with Flex 1.5), it crashes my browser (Firefox or IE) when I confirm the activation of my webcam (Logitech QuickCam). Uninstalling the debug player and installing the current Flash player 7.0.19.0 solves the problem (webcam can be activated). Anyone has run successfully the app with a webcam and the debug player?

Subclass method signatures *must* match superclass methods?
I have encountered a behavior that *might* be a bug but I wanted to get some input from folks before submitting it... Perhaps there is a simple workaround? One of the major reasons to use Object Oriented Programming is because we can create abstract, generalized super classes and then create concrete subclasses that expect and create more specificity. (Polymorphism) The way this is implemented in Java (and other strongly-typed languages) is by using Method Overloading and Method Overriding. A subclass simply redefines a method with the same name as a superclass but implements a more specific argument and/or return type. In ActionScript, we don't get method overloading - Which is fine by me as it can often lead to a lot of verbose code and probably a bloated/slower runtime environment since we would then need runtime type-checking. When using the Flash IDE, I can write an abstract superclass that expects or returns a more generic object (Let's say Object for example). Then I can create a subclass that expects a more specific implementation of that object. (Let's say ConcreteObject) This would be known as a simple Method Override... This fails in Flex because the compiler complains that the subclass must implement the *same* method signature that is found in the super class. For a good example, try extending Array and overriding one of it's built-in methods but accept or return a custom object rather than Object Object. That behavior is fine with me - IF - we are ALSO given the ability to overload methods, but without that capability, this problem renders the Flex Compiler pretty useless for real, Object-Oriented architecture because it fundamentally prevents polymorphism. Hasn't anyone else run into this? Please forgive me If this has already come up, I would be glad to have a link to some related conversation if you know of one and I would be even happier if there is a simple flag or workaround to make this work.

Re: [flexcoders] Subclass method signatures *must* match superclass methods?
My cliche answer is use Composition.
Another way:
import Moo;
class JXLArray extends Array
{
public function push(val):Object
{
return Moo(this.push(val));
}
}
Simply typecast.
Lastly, it doesn't fail; mine compiles; it's just Flex whines, but I still
can run it.

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

Well, many thanks to you for help me.
I know about webservice and I have already realized an insert to
datebase
through Flex with simple textimputs or textareas, but my trouble is
about a
checkrenderer. I must count records of a datagrid, see which of those
records they are checked, and extract the value of a column of the
above
mentioned record. In .NET everything is very explicit, but in Flex I
do not
know that codes to use in the .as code of my .mxml file.
I know that to count rows of a datagrid i can use rowCount, but for
others
two tasks I cannot which option use (rowIndex, i don't know)
sorry for my poor english, and i hope you understand me.
many thanks in advance

Miguel,
Actually i´m learning to use Macromedia Flex and i´m working
with
a checkrenderer datagrid, but in this moment i have a trouble.
I need to do a insert info a for(...) sentence, but i can´t find
correct code for do that.
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

ChangeEvent on component in mxml component
Hi everyone.
I have a mxml component with a ValueObject in it. I am binding to the
valueobject where I use the component. How can I generate an event when
the data changes?
My code is something like this:
MyComponent data={asdf}/
in MyComponent.mxml I have something like:
ValueObject id=data/
ValueObject is a .as file.
So how do I generate an event when {asdf} changes?
Thanks in advance.

Hi all,Long-time lurker, first-time poster... I wanted to draw your attention to an issue that I'm having with Flex Builder: Basically, the Preview/Run/Debug functionality stops working when you subclass mx.core.Application and/or mx.containers.Form in your applications.Of course this is a perfectly legal thing to do and, actually, the ARP framework will be recommending this as a best practice (among other things, it makes migrating from Flash to Flex child's play.) It also gets around having to mix code into your MXML files -- which is a nasty practice akin to how we used to #include script files in ActionScript 1 in Flash. In any case, this is a fundamental use case and it appears that Flex Builder doesn't currently support it. I posted about this on my blog in more detail, with a barebones sample to demonstrate the bug:http://www.flashant.org/index.php?p=273more=1c=1I am still holding out hope that there is a way to override this default behavior in Flex Builder to tell it that it's ok to preview a subclass of Application/Form but I haven't been able to find such a way using the Dreamweaver extensibility APIs. Perhaps someone from the Flex team will have a potential solution/workaround for this.All the best,Aral -- Aral BalkanManaging Director, Ariaware Ltd.Best Practices Flash Flex Development course - March, 2005.
