No, I don't believe that will work.
I would just use the labelFunction to get the string value when I needed
it programmatically:
var sFullName:String = getFullName(myDataGrid.dataProvider.getItemAt(0))

Subject: [flexcoders] Flex 1.5: Using columnName + labelFunction in a
DataGrid
Hi all,
Please, how can I get the data value of a DataGrid cell when the
DataGridColumn uses a labelFunction?
--
mx:DataGridColumn headerText=Full name columnName=fullname
labelFunction=getFullName editable=false /
--
private function getFullName(item: Object, columnName: String): String {
var str;
item.FULLNAME == undefined?
str=null :
str=item.FULLNAME.FIRST+ +item.FULLNAME.LAST;
return str;
}
For example, should
myDataGrid.dataProvider.getItemAt(0)[fullname]
return John Smith ?
I always get an undefined value...
Thanks!

[flexcoders] Flex 1.5 ViewStack child creation
I'm using the following ViewStack within my application:
mx:ViewStack id=myViewStack height=100%
cmp:FirstView id=firstView /
cmp:SecondView id=secondView /
cmp:ThirdView id=thirdView /
/mx:ViewStack
I've been reading about the ViewStack component and found that children
(except the first one) are only created when the user explicitly makes
an action that causes the selected child to change as:
function myButton.click() { myViewStack.selectedChild = thirdView; }
What I'm realising is that children are ALL created, in a sequential
fashion, but CREATED in fact. Why is this happening? Should I set a
creationPolicy property to none and then instantiate the views
manually? If so, which is the best way to do it? createComponent()?
createChild()? createClassObject()?
Please, help me... :-S
Thanks!

[flexcoders] Re: Flex 1.5 ViewStack child creation
Hi Stanislav, what I'm trying to do is just the opposite: avoid
children to be created at the begining. After reading the
documentation I can't understand why this is happening... I've put a
trace sentence at the initialize property of each child and I've
debugged the application. The trace message is shown for each of the 3
children in myViewStack!
Thanks for your response :)

From Help:
Navigator containers such as Accordion, TabNavigator, and ViewStack
implement the auto policy by creating all their children immediately,
but wait to create the deeper descendants of a child until it becomes
the selected child of the navigator container.
So if you want to create all your childrens at one time, just use
creationPolicy=all

[flexcoders] Sending ISO-8859-1 from a Flex application
Hi all,
I'm trying to send an XML over HTTP from a Flex application to a
Cocoon framework which redirects the requests to PL procedures in
order to access an Oracle database ISO-8859-1 encoded.
mx:HTTPService id=srvXMLoverHTTP
url=http://.../cocoon/.../myCocoonEntry;
contentType=application/xml
resultFormat=xml
mx:request
myXML{objXML}/myXML
/mx:request
/mx:HTTPService
Where:
objXML = new Object;
objXML.afield = áéíóú;
So this XML is generated from the object objXML:
myXML
afieldáéíóú/afield
/myXML
Which encoding does this XML use? UTF-8?
Has it something to do with the encoding specified at the header of my
Flex application (UTF-8)?
The characters sent are not well inserted into the database. Is it
possible to send an ISO-8859-1 XML document from my Flex application
using the HTTPService tag?
S.O.S.

[flexcoders] Form input encoding (ISO-8859-1 or UTF-8?)
Hi all, I'm wondering which character encoding is used when you enter data in a Flex form... I have installed a MySQL database on my computer. My Flex application accesses the DB through an HTTPService which url points to a JSP. This JSP accesses the DB and returns an XML to my Flex application. All works fine with queries (only for reading from the DB), but not with inserts. I'm having problems using characters á, é, í, ó, ú. When I enter them in a Flex form, they're properly displayed on the screen but not in the DB (I get strange characters when administering the DB with MySQLFront). I've tried to change the DB encoding (from latin1 to utf8 and viceversa). I've tried to change my application encoding, the JSP encoding (pageEncoding) and the encoding of the returned XML... Is there any valid combination of encodings for my application to work properly? :-S -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

Thank you Omar, I tried your approach but it didn't work... I'll keep
on trying :-S

Hi,
On your cell render you can use these properties.
public var listOwner:mx.controls.List;
private var getCellIndex:Function;
private var getDataLabel:Function;
So instead of using parent use listOwner.parent, that should give you
access to your button. Another aproach is to dispatch the button
event into
the TileList and then on your cellrender listen to it using
listOwner.addEventListener(myEvent). Let me know if this was of
any help.

[flexcoders] HTTPService: Security error accessing url
I have the following code in my Flex 2.0 application. Basically I'mtrying to send a HTTP request to a remote computer with Cocooninstalled. The entry actualitza1.xml reads the http request parametersand calls the PL procedures that access the database. When it attemps to reach the specified url in the mx:HTTPService tag, it launches the following error: "Security error accessing url"When I debug the application, I get a Sandbox security violation... can anyone help me with this, please... May I use a crossdomain.xml file somewhere in the remote computer?? May I write a destination entry in the Flex configuration files?Any help will be appreciatedThanks!?xml version="1.0" encoding="utf-8"?mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml" xmlns="*" initialize="srvpost.send()" mx:Script ![CDATA[ import mx.controls.Alert; ]] /mx:Script !-- Security error accessing url -- mx:HTTPService id="srvpost" method="POST" useProxy="false" resultFormat="xml" fault="Alert.show(event.fault.faultstring);" result="myText.text=srvpost.result.toString()" url="" mx:request fdni155959792/fdni ftlf971232323/ftlf fmail[EMAIL PROTECTED]/fmail /mx:request /mx:HTTPService/mx:Application -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com YAHOO!
