Multitline in a list labelField
I am working on flash builder 4.5.1 (mobile application) and i want to show the labelfield in multiline. How can i do that ?
Hi,
Following Action Script class might help you:
package components
import mx.core.UITextField;
import flash.text.TextFieldAutoSize;
import mx.controls.Label;
import flash.display.DisplayObject;
public class MultiLineLabel extends Label
override protected function createChildren() : void
// Create a UITextField to display the label.
if (!textField)
textField = new UITextField();
textField.styleName = this;
addChild(DisplayObject(textField));
super.createChildren();
textField.multiline = true;
textField.wordWrap = true;
textField.autoSize = TextFieldAutoSize.LEFT;
Thanks and Regards,

Unable to set Labelfield for child element in List
Hi All,
Below is code I am trying to execute
<?xml version="1.0" encoding="utf-8"?>
<mx:Application

true" id="list" labelField="
chidren.lastName" /></mx:Application>
I basically want to access the children.lastName on my List. Please let me know how exactly can I do it.
labelFunction is the best way to do this. The attached code also shows how to do it with an itemRenderer, though that would not be as efficient.

Whats the best practice to simply manage data using php sql?
Hi
I'm trying to follow some tutorials but there is too much old material and I'm getting confused.
This is basic. I have a db and I want to movement data from flex.
So, this is how I'm trying to do so. As a newbie, I will try to be clear.
I have created a simple table called "teste" using myphpadmin with only 2 fields for testing. (id, name).
I have created the services automaticly using flex to generate a php code.
This code is a simple exercise with buttons to add, update, and delete a Item.
Although there is a lot of auto-generated code, I had a lot of work (due to my ignorance) to make it work.
It fairly works, but I know veteran users would make it better, smarter, shorter, and ALL I WANT is a better (and simple) example to follow
Please.
Thanks in advance
ps. I have set my table field "name" to the 'utf8_unicode_ci' while creating it and I it seems the adobe's generated php can't handle latin chars.

Sorry - I had to read up on what a base table block was.
I think I am. In this particular form I have one block - a customer block which has its items pulled in from the customer table, no problems there, it works fine.
My problem is I need to make it as user friendly as possible, if the user inputs the wrong customer ID (or does not know their name) I want them to be able to scroll through the customer list using an up or down button.
When do you have the commit_form statement run, (the OK button) after every change or after a block of changes ? Commit writes the changes to the database giving other users access to that data right ?! How often should it be used ?
Is it possible to implement a 4bit image?
Hi!
I have some exotic image files with one, 16bit channel. Currently I am able to display them in flex by translating this to 4 8it channels in a bitmapData and using a shader. But, the problem with this is it takes twice the memory it should (16bit to 32bit...).
I am wondering is it possible to somehow extend the BitmapImage class and override important methods to somehow solve this problem?
Thx for help!
So I've done some testing with PNG formats, with test cases from this page: http://www.schaik.com/pngsuite2011/pngsuite_bas_png.html
Flex handles all this formats well, but it still converts the output to raw 4 8bit channel BitmapData :/
Test in the Profiler with this code:

Iterating through openItems (Tree)
I have a tree called cat_tree, which looks like:
<mx:Tree id="cat_tree"
dataProvider="{categories_list.list}" labelField="@label"
showRoot="true" width="375" height="250"
change="event.currentTarget.editable=false;updateGroups()"
editable="false" itemClick="event.currentTarget.editable=true"
itemEditEnd="event.currentTarget.editable=false;updateCategory()"/>
Oh and by the way, if you ever wanted to figure out that
problem of making a tree only editable on double-click, the above
is the answer. Sorry, to go off on a different tangent here, but I
know people have butted their heads against walls on this one from
browsing through some forums. You simply just set editable to
"false" and then for itemClick, you set it to
"event.currentTarget.editable = true", then for itemEditEnd, you
set the value to "event.currentTarget.editable = false" and for
change you set the value to "event.currentTarget.editable = false".
Basically what that does is when you click on an item (before
you click on an item, editable is set to false, so it doesn't go
into "edit" mode), it turns on editability for the tree. Then, when
you click again, since editability is now enabled, it goes into
"edit" mode. ItemEditEnd tells the tree to turn off editibility
when you finish editing the item again. So, this works great, but
if you then click on one node of a tree and then click on another,
it goes straight into edit mode, so then you add change and set it
to "event.currentTarget.editable = false", so when you change
nodes, it resets the editability to false and then (luckily)
itemClick gets called after change, so then itemClick starts it's
process all over again.
I hope that all made sense. Anyways, if you need to use this
a lot, I would advise putting it into a custom component.
So, that tells you why the above code might look a little bit
"funky". Anyways, moving on to the real reason of my post...
I have a function called updateCategory which gets called
after a node is edited. Basically, I want to store the values in
tree.openItems and then restore them when the dataProvider gets
updated (the dataProvider is an HTTPService that gets resent).
My function looks like:
private function updateCategory():void{
var openedItems:Array = new Array();
Alert.show(cat_tree.openItems.children().length());
x:int;
for(x = 0; x < cat_tree.openItems.length(); x ++){
openedItems[x] = cat_tree.openItems[x].@id;
var new_name:String =
TextInput(cat_tree.itemEditorInstance).text
var rVars:Object = new Object();
rVars.new_name = new_name;
rVars.category = cat_tree.selectedItem.@id;
categories_list_http.send(rVars);
x:int;
for(x = 0; x < openedItems.length(); x ++){
cat_tree.expandItem(categories_list.list.node.(@id==openedItems[x]),true,false,false);
Should this work in theory, or am I totally off the mark. I
had initially tried something like:
private function updateCategory():void{
var openedItems:Object = new Object();
openedItems = cat_tree.openItems;
var new_name:String =
TextInput(cat_tree.itemEditorInstance).text
var rVars:Object = new Object();
rVars.new_name = new_name;
rVars.category = cat_tree.selectedItem.@id;
categories_list_http.send(rVars);
cat_tree.openItems = openedItems;
but that didn't work at all.
Any pointers.
I know, I could just use a second HTTPService call and use
that for updating and have my initial one just never refresh, and I
may have to do that, but now my curiosity has gotten the better of
me.
I've got it to finally work with openItems. I blogged the
complete source on my
blog.
Here's snippets from my code.
In the Script tag:
[Bindable]
public var tempOpen:Object = new Object();
[Bindable]
public var refreshSO:Boolean = false;
public function switchDP():void
tempOpen = testTree.openItems;
refreshSO = true;
if (currentDP == "tempObject")
currentDP = "secondObject";
testTree.dataProvider = secondObject;
else
currentDP = "tempObject";
testTree.dataProvider = tempObject;
public function renderFunc():void
if (refreshSO)
refreshSO = false;
testTree.openItems = tempOpen;
In my mxml code:
<mx:Tree id="testTree" render="renderFunc()" width="250"
click="onTreeNodeClick(event)" dataProvider="{tempObject}"
labelField="label" />
That works beautifully for me!
Excuse me if this problem has an obvious answer but I am new to flex.
Consider the following mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" verticalGap="0" paddingLeft="0" paddingRight="0" paddingTop="0" paddingBottom="0">

<mx:Text text="Message 1"/>
<mx:Text text="Message 2"/>
</mx:VBox>
<mx:HBox width="100%" >
<mx:VBox width="30%" backgroundColor="#AE5E8D">
<mx:Text text="Configuration Summary" fontSize="15" color="#FFFFFF"/>
<mx:List labelField="name" width="100%"/>
</mx:VBox>
<mx:VBox width="70%" backgroundColor="#AE5E8D">
<mx:Text text="Recent Activity" fontSize="18" color="#FFFFFF"/>
<mx:DataGrid rowCount="10" width="100%" >
</mx:DataGrid>
<mx:Text text="Events" fontSize="18" color="#FFFFFF"/>
<mx:DataGrid rowCount="10" width="100%" >
</mx:DataGrid>
</mx:VBox>
</mx:HBox>
</mx:Application>
When this renders I am left with a small gap on the left hand side of the browser.
When I remove the text line <mx:Text text="Events" fontSize="18" color="#FFFFFF"/>
It goes away.
Can anyone tell me why this is?
Hi,
It seems to happen when scrollbar appears. Try to turn off vertical scroll policy:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

paddingLeft="0"
paddingRight="0"
paddingTop="0"

Hi, I'm using an accordion component with 2 nested repeaters,
the visualization is OK, except I cannot get rid of a vertical gap
in the list between my sections. The list displays correctly the
items of my first section and after that, it has a gap and then
section 2. How could I get rid of that gaps?
Thanks in advance

I might stop using repeaters and have a custom component for
each course. There will be many common elements in each course,
probably each will have sections, or perhaps some will not. In any
case, just iterate through the xml data provider and create
instances of your course custom component, which can be based on
VBox as root container. This might help.
Component life cycle doesn't apply to objects created w/in ActionScript block??
i don't understand why init() is never called. typically one can initialize variables in the constructor, but since this is mxml, the constructor is automatically created for us and the programmer seems to have no access or override privileges. so what to do?? am i failing to grasp some aspect of the component life cycle process?? how should i go about initializing properties??

NOTE: the code above might seem a little ridiculous, but that's b/c i reduced it down. imagine a baseComponent and derivedComponent where the myString has a default value in the base case and needs to be overridden in the derived case. appreciate any insights and thanks,

I suppose I should have been more aware about when the initialize event gets dispatched -- the concept just wasn't registering for me and I was totally miffed about how to initialize variables on construction.
Do you have to initialize before the instance is added to the display list?
Yes, I was mixing both mxml and AS classes and the derived classes had no display objects to attach to the stage (they were mostly classes made to modify run time behavior). You can check out my previous post, which gives the code for where or why this might be needed.
I ended up initializing mxml class variables during construction in the following way:
------------------------------ classes/BaseClass.as ------------------------------
package classes
public class BaseClass
public var myString:String = "hello, world";
public function BaseClass() {
init();
protected function init():void {
// intentionally left empty

How to binding incoming xml node list to the tree control as dataProvider
Recently, I faced into one issue: I want to binding incoming xml node (it's not avaliable at start) list to the tree control as a dataProvider.
Since the incoming xml node list is not avaliable at beginning but I needs to bind it to the tree, so I create one virtual one in the xml, and prepare to remove it before the tree is shown. (ready for the actual node adding). But It did not work.
Please see the presudo-code here:
1. Model layer(CsModel.as)
public class CsModel
[Bindable]
public var treeXML:XML=<nodes><car label="virtualOne" id="1">
</car></nodes>;
(Here, I want to build binding relationship on the <car/> node,
one 'virtual/stub' node is set here with lable="virtualOne".
But this node will be deleted after IdTree
control is created completely.)
[Bindable]
public var treeData:XMLList =new XMLListCollection(treeXML.car);
2. view layer(treePage.mxml)
private var _model:CsModel = new CsModel();
private function addNode():void
var newNode:XML=<car/>;
newNode.@label="newOne";
newNode.@id=1;
_model.treeXML.appendChild(newNode);
private function cleanData():void
delete _model.treeXML.car;
<mx:VBox height="100%" width="100%">
<mx:Button label="AddNode" click="addNode()" />
<mx:Tree id="IdTree" labelField="@label"
creationComplete="cleanData()"
dataProvider="{_model}"/>
</mx:VBox>
3. Top view layer (App.Mxml)
<mx:application>
<treePage />
</mx:application>
For method: cleanData()，It's expected that when the treePage is shown, we first delete the virutalOne to provide one 'clear' tree since we don't want show virtualOne to the user. The virutalOne node just for building the relationship between treeData and treeXML at beginning. But the side effect of this method, I found, is that the relationship between treeXML and treeData was cut off. And this leads to that when I added new node (by click the 'addNode' button) to the xmlXML, the xmlData was not affected at all !
So Is there any other way to solve this issue or bind the incoming xml node list to the xmlListCollection which will be used as Tree control's dataProvider ?

<xsl:eval>this.selectSingleNode("name").nodeName</xsl:eval> : <xsl:value-of select="name" />

dragEnabled="true" dropEnabled="true" dragMoveEnabled="true"
labelField="category"/>
</mx:VBox>
user drags one or more items from the source to dest list.
This works great.
Now I need to pass the dropped/selected data in destlist to
myobj, along with the other form items. How?
<mx:Script>
<![CDATA[
private function sendFormdata():void {
var myobj:Object = new Object();
myobj.name = myname.text;
myobj.email = myemail.text;
myobj.entry = myentry.text;
myobj.entrycomment = myentrycomment.htmlText;
myobj.selectedcats= destlist.????
cfdataInsert.addData({user:myobj})
]]>
</mx:Script>
Second part of my question is that I want the value of
myobj.selectedloops to be a comma separated list of categoryid
numbers (e.g. 1,3,5). My query, that populates the source list via
the remoteobject contains categoryid,category, and description
columns. I currently display the category in the labelField of the
list, but I need to submit the categoryid to the DB.
data comes from...
<mx:RemoteObject
id="cfdata" showBusyCursor="true"
destination="ColdFusion"
source="da8.Constellation.entries">
<mx:method name="getCats" result="getCats_result(event)"
/>
</mx:RemoteObject>
getCats ColdFusion function...
<cffunction name="getCats" access="remote"
returntype="query">
<cfset var CatData = "">
<cfquery name="CatData" datasource="#DSN#">
select categoryid,category,description
from Categories
order by category
</cfquery>
<cfreturn CatData />
</cffunction>
and then this function populates the srclist with the
data....
public function getCats_result(event:ResultEvent):void
srclist.dataProvider = event.result as ArrayCollection;
destlist.dataProvider =[];
How do I pass the resulting destlist categoryids to
myobj.selectedcats ?
I don't know how the ArrayCollection organizes the query and
how to reference the categoryid in the srclist and destlists.
I'd appreciate any help.
Thanks,
Don

How to search XML data from a HTTPMultiService and display the result on the Spark List
Hello all,
I am totally new to Flash Builder and Actionscript and hope someone might be able to help me out. I basically create a mobile app with a single view. The view has a TextInput as a search box and a search button. I conntected a Data/Service using a local XML file and bind the Data to a Spark List. Innitally the List will show nothing until the user enter the search term and hit the button. The List suppose to show the XML data that match the search term.
Now is my problem. I cannot make the List to show the data that match the search text. The List just shows ALL the data.
Here are my MXML code:
<?xml version="1.0" encoding="utf-8"?>

The getSearchData() supposed to return XML data that match the search text, but it doesn't. Can anyoen help?
Thank you!
Hi,
are you able to change dynamically the operation.url = "assets/data/shopping.xml";?
i need to do that based on the users input.
Thanks in advance,
Issue Putting Data from ArrayCollection into List
I'm having trouble getting data that has been pulled from a textArea and put into an ArrayCollection to be displayed in a List. The data is being saved and then read as a file from local storage. When I run the application, nothing appears in the created list even though I get no compile-time errors.
Here is my List code:

Off topic: I noticed you are binding the label value of the renderer to the data. It's recommended that you use the labelField property on the List instead for better performance on mobile, for example:
<s:List id="myCardsList" labelField="textTitle" ...>
<s:itemRenderer>
<fx:Component>
<s:MobileIconItemRenderer />
</fx:Component>
</s:itemRenderer>

Populating a drop down list of users using JSON from a REST call
Hi guys,
First post, have just started the mammoth project of turning us paperless.
My first task has been to create a header template - this header to be used on any form we use. I got this done almost without issue, it seems the only complication is to attach the username to the document.
Initially I tried to do this with a text field. I set this up with a calculation script to set this.rawValue = identity.username (also tried identity.name), however further reading taught me that that requires priviledged context (haven't figured out what that is or how to get it yet, but it seems like a 'no' for this method).
My next step has been to attempt to let the user pick their username from a list. "Easy!" I thought, "I just set up a webscript last week to return a configurable list of user details. My web script (it runs off of Alfresco CMS, for the record) is accessed from an URL like https://docs.ourcompany.com:8443/alfresco/service/ourcompany/users?useGroup=[a user group]&filter=[a filter string] and returns JSON like this:
"users" :
"name" : "Chris O'Kelly", "userName" : "ChrisO"
"filter" : "all",
"error" : 0
In the layout:ready script section for my dropdown I have used the following js
function createRequest() {
var result = null;
if (window.XMLHttpRequest) {
// FireFox, Safari, IE>6
result = new XMLHttpRequest();
if (typeof xmlhttp.overrideMimeType != 'undefined') {
result.overrideMimeType('application/json');
else if (window.ActiveXObject) {
// IE <7
alert("No available type");
result = new ActiveXObject("Microsoft.XMLHTTP");
else {
alert("No available type");
return;
return result;
var req = createRequest();
req.onreadystatechange = function() {
if (req.readyState != 4) return;
if (req.status != 200) {
alert("REST call failed");
return;
// Request successful, read the response
var resp = req.responseText;
this.addItem(resp.users.name, resp.users.userName);
req.open("GET", "https://docs.ourcompany.com:8443/alfresco/service/ourcompany/users?useGroup=GROUP_EveryUser&filter=status", true);
req.send();
But when I preview the form I get nothing, no errors, no alerts, no filling of the dropdown. I've read a few conflicting forum posts on whether or not xmlHttpRequest works within liveCycle forms, so I suppose the guts of my question boils down to- does it?
Hi!
In the DropDownList set the labelField property to the name of the object property you want to appear.
Ex:
<s:DropDownList labelField="facilityNumber"
includeIn="NewInspection"
dataProvider="{ddFacNum}"
fontFamily="Arial" fontSize="16"
id="ddFacilityNumber"
prompt="Select facility number..."/>
Help with a vertical scroll bar issue with a List component
hi. i have a basic <s:list> that uses an XMLListCollection as it's data provider and a very basic itemrenderer. when a row in the list is clicked a function gets the list.selectedIndex then populates some text fields with more xml data. that all works fine.. the problem i have is that the vertical scroll bar on the list seems to be "clickable" - just like a row in the list. the scroll bar scrolls normally but when it's clicked the selectedIndex becomes -1 which is not helpful b/c the value -1 is passed to the XMLListCollection.
any ideas? cheers.
thanks but still problematic...surely the <s:List> component shouldn't return a value when the scrollbar thumb is clicked? i created a very basic list (see below) and made the list dimensions short enough so that there is a vertical scrollbar and found that when the scrollbar thumb is clicked the trace(event.currentTarget.selectedIndex) returns a number. that's annoying b/c i just want a selectedIndex value for a row that is clicked not the scrollbar.
any ideas to get around? cheers
