[flexcoders] setting focus back to component that fails validation?
I create a form dynamically and need to do my data validations
within ActionScript code. I generate a TextInput component that
must be numeric. What I'd like to have happen is that if the
user enters non-numeric data, I issue an alert; when the user
clicks ok, the focus goes back to the TextInput field that failed
validation. However, I can't get the focus to go back to the
failed component (even if I dont issue an alert). Code snippets
below, any ideas what I'm doing wrong?
Thanks in advance:
mxml snippet
ActionScript:
var myValidator:NumberValidator = new NumberValidator();
public function itemChanged(event): Void
{
var ok:Boolean =
NumberValidator.validateNumber(myValidator,
event.target.text,
null,
"text");
if (ok == false)
{
// Force focus to failed component
event.target.setFocus();
}
}

[flexcoders] drilling down to get dynamically generated form values
I create a form dynamically using a repeater shown below. When the user hits the "Submit" button, I want to be able to "drill down" to get all of the values for the TextInput fields. How can I get to them in ActionScript code for submitForm() starting from "form1"? Thanks in advance. Yahoo! Groups Sponsor ~--> Fair play? Video games influencing politics.

[flexcoders] passing array of Form values in VO
I want to have a form on the client side that accepts
a list of items of the same type/meaning, for example people's names.
I would then send a value object to a server side Delegate object
using the construct.
However, I don't know how to indicate that a form variable
is an "array" without getting duplicate component id errors.
In essence, I want to do what is shown below. How can I have a
"vector" form variable using Flex?
Thanks in advance.
mxml file:
Client side value object:
-
class Foo
{
public var names: Array;
}
Server Side value object:
-
public class Foo
{
private String[] names; (or List)
// accesors
}

[flexcoders] Does Flex have equivalent of JSTL ?
I need to iterate through a collection of polymorphic objects and build a form dynamically. Depending on the current type of object, I need to output 1, 2, or 3 components. I'm using a Repeater to iterate through the collection. Does Flex have the equivalent of JSTL or some other logic tags that will let me conditionally generate mxml? Thanks in advance. Yahoo!

[flexcoders] can flex build dynamic form
I was wondering if Flex has the equivalent of the Struts tag and the JSTL tag to perform conditional rendering? I have alist of polymorphic objects that I need to both display and allow updates to by the user. Each object (based on its type) may have 1, 2, or 3 input fields. I need to loop through the object list and build a dynamic form, outputting the correct number of input fields for each object. I can do this in Struts/JSTL but is there a way to do it Flex?

[flexcoders] custom data grid solution
I have a requirement for a custom data grid: 1. 1st column will be a "link" value. you click on it and it takes you to a different view in a viewStack. 2. columns 2 through n-1 will be regular Strings 3. column n will be a checkbox. What's the best approach for building such a custom data grid object? Are there any examples out there that show something like this? I imagine that I will need to extend the DataGrid object to add 2 different column Renders for columns 1 and n? Any pointers/references appreciated. Yahoo!

[flexcoders] Newbie Question about Value Objects on client side
I've been reading the docs for about 2 days now and have a simple
question I can't find the answer to. Please no flames, I have made
an attempt to find the answer to this question by reading all the
documentation I can find.
I'm using Flex with Websphere 6.0. I have a POJO business delegate
class that returns a value object. I access the delegate class from
my mxml file using the mxRemoteObject tag. Suppose I have a very
simple Value Object on the server side called Person that is being
returned by the business delegate:
public class Person
{
private String firstName;
private String lastName;
// get & set accessors
}
I'd like to use the values returned in the Person object to populate
controls on the client side, display data, etc.
QUESTION:
Do I *have* to create a corresponding Person class on the client side
using ActionScript to access the attributes (firstName and lastName)
on the client, and use registerObject()? If I don't create a
corresponding Person class on the client side, how I can I access the
properties in the Person object returned? What am I getting back on
the client side?
I'd rather not create analogous value objects on the client side if I
can avoid it, to avoid the classes getting out of sync.
Thanks in advance for any help! Pointers to documentation that
address this (which I obviously cannot find) appreciated.

[flexcoders] accessing returned ValueObject properties in mxml file
I want to access the properties of a Value Object returned from a
Java business delegate to populate some flex controls (label text,
grid data, etc.). However, I do not want to have to write an
analogous Value Object class in ActionScript code (don't want to have
to keep them in synch). Is this possible? If so, how? I have not been
able to find documentation that addresses this.
Here are background details:
On the server side I have:
--
public class HelloDelegate
{
public HelloVO getHello()
{
return new HelloVO();
}
}
public class HelloVO implements Serializable
{
private int id;
private String name;
// get accessors for id and name
}
On the client side I have:
--
hello.mxml:
public function getHello():Void
{
var pendingCall = helloDelegate.getHello();
pendingCall.resultHandler =
mx.utils.Delegate.create(this,gotHello);
}
private function gotHello(result) : Void
{
// At this point result is a HelloVO value object. How can I
// access id and name properties here?
}
