[flexcoders] RichTextEditor's Minimum Size
Is there any way around RichTextEditor's minimum size? It has a minimum size of 220 pixels wide by 200 pixels high, which is just too big for my application. If I set the size to smaller than this scroll bars appear *within* the control. Cheers, David.
[flexcoders] Re: RichTextEditor's Minimum Size
Got it! Set the textArea subcomponent's size: form.txtField.textArea.height = form.txtField.height; What a faff! Can anyone explain why I have to do this? --- In flexcoders@yahoogroups.com, triggersoftware [EMAIL PROTECTED] wrote: Is there any way around RichTextEditor's minimum size?

[flexcoders] Flex Builder 3
I've upgrade to Flex Builder 3 and noticed that it's more pedantic about
how I form my web service calls. The following code WORKS:
const service:WebService = new WebService();
service.loadWSDL(http://d6zltz1j:8080/Misura360/RespondentService?wsdl\
);
service.addEventListener(FaultEvent.FAULT, onFault);
service.addEventListener(ResultEvent.RESULT, onResult);
var loginOperation:Operation = new Operation();
loginOperation.name = login;
loginOperation.request = new
Login([EMAIL PROTECTED], db);
service.operations = {login : loginOperation};
service.login();
...but this doesn't:
const service:WebService = new WebService();
service.loadWSDL(http://d6zltz1j:8080/Misura360/RespondentService?wsdl\
);
service.addEventListener(FaultEvent.FAULT, onFault);
service.addEventListener(ResultEvent.RESULT, onResult);
service.login(new Login([EMAIL PROTECTED],
db));
The onResult handler is still called, but my result object is NULL. How
come?
[flexcoders] Web Services and Arrays
I've been connecting our Flex app to Web Services written in JBoss for the first time and noticed some odd things happening when the web service sends back an array. This problem basically goes away if you change the operation tag's resultFormat attribute from object to e4x. Can anyone explain this? Here's the soap message that is coming back: env:Envelope xmlns:env=http://schemas.xmlsoap.org/soap/envelope/; env:Header/ env:Body ns2:fetchLookupsResponse xmlns:ns2=http://session.misura.triggersoft.com/; return functions descriptionHR/description functionId1/functionId /functions functions descriptionFinance/description functionId2/functionId /functions functions descriptionIT/description functionId3/functionId /functions grades descriptionG01/description gradeId1/gradeId /grades grades descriptionG02/description gradeId2/gradeId /grades grades descriptionG03/description gradeId3/gradeId /grades /return /ns2:fetchLookupsResponse /env:Body /env:Envelope According to JBoss, this is how lists are sent over soap. [shrug] When the operation is defined as having a resultFormat of object, the structure of the ResultEvent is as follows: event:ResultEvent - result:ObjectProxy - return:ObjectProxy - functions:ArrayCollection [0] ComplexString - value = HR [1] ComplexString - value = 1 [2] ArrayCollection [0] ComplexString - Value = Finance [1] ComplexString - Value = 2 [3] ArrayCollection [0] ComplexString - Value = IT [1] ComplexString - Value = 3 - grades:ArrayCollection [0] ComplexString [1] ComplexString [2] ArrayCollection [3] ArrayCollection As you can see, the first two elements of the array should really be sub-elements. However, when I change the resultFormat attribute from object to e4x the output is as follows: event:ResultEvent - result: XMLList [0]:XML - ns2:fetchLookupsResponse - return - functions - description HR - functionId 1 - functions - description Finance - functionId 2 - functions - description IT - functionId 3 - grades ... Can anyone explain why the object version behaves so strangely? Cheers, David.
[flexcoders] Re: Web Services and Arrays
It looks to me like the Flash deserialising code can't deal when an array is sent back with other objects at the same level: someObject grades grades grades someOtherObject /someObject It doesn't work properly out that it's an array unless all sibling nodes are of the same type: someObject gradeWrapper grades grades grades /gradeWrapper someOtherObject /someObject

That's rubbish! Who at Adobe do I have to bribe? I've never submitted a Bug report to Adobe before. Where should it be done? Here ? http://www.adobe.com/bin/fp9betafeedback.cgi
[flexcoders] Re: Web Services and Arrays
For anyone else having this problem, you can also get round it by setting the resultFormat to e4x as it properly preserves lists. var service:WebService = new WebService(); service.loadWSDL(http://d6zltz1j:8080/Misura360/RespondentService?wsdl\ ); service.addEventListener(ResultEvent.RESULT, onResult); service.addEventListener(FaultEvent.FAULT, onFault); service.fetchQuestionnaire.resultFormat = e4x service.fetchQuestionnaire(new FetchQuestionnaire(5))
[flexcoders] Summary Data
I have two grids. The first has a list of users: User Type --- Bob IT James Marketing Mark Marketing Stef Sales The second contains a summary view of the users *by type*: Type Count --- IT 1 Marketing 2 Sales 1 These two grids are on the same form. As users are added to the first grid I want to the second grid to refresh. How do I do this? In other languages/frameworks I would write an adapter for the summary grid, but am unsure of how/where to do this in flex. Cheers, David.

[flexcoders] Re: Summary Data
Just adjust it's data provider to match the new summary data, from your existing add method. Are you talking about adding something into the method which adds a user to go and recalculate a separate model which is bound to the summary table? If I understand you correctly then I'd have to fire this summary refresh when I removed a user as well. I would have expected data binding to tell the grid to refresh its data rather than me doing it manually. --- In flexcoders@yahoogroups.com, Tom Chiverton [EMAIL PROTECTED] wrote: On Thursday 06 Dec 2007, triggersoftware wrote: These two grids are on the same form.

[flexcoders] Re: Summary Data
Maybe if you showed us how the two things are wired up together at the moment, we'd could be more specific. The summary grid is not wired up yet. I just a have my main grid of users and I want to add the summary grid. The kind of thing I was expecting to do was to simply define a datasource for my summary grid and that datasource to define a dependency on the main grid's datasource. Therefore if any of the main grid's data changed (user added/edited/deleted), the summary grid would be refreshed. ?xml version=1.0 encoding=utf-8? mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; mx:Label text=Users:/ mx:DataGrid mx:ArrayCollection id=users mx:Object name=David type=IT/ mx:Object name=Simon type=IT/ mx:Object name=Chris type=Management/ mx:Object name=Andy type=Support/ /mx:ArrayCollection /mx:DataGrid mx:Label text=Summary:/ mx:DataGrid mx:ArrayCollection id=summary source=/ /mx:DataGrid /mx:Application

[flexcoders] Transition when reverting to the base state
I know how to get a component removal transition to work when I'm
actively calling mx:RemoveChild, but I'm not sure how to get a removal
transition to work when components are removed by Flex to undo the
calls to mx:AddChild which moved us into the current state in the
first place.
Okay, that probably doesn't make much sense, so here's a simple
example. How do I get the mx:Fade transition to be applied to the

After a bit more playing, I can see that both effects are definitely
getting run, it's just that I can't see the A - Base transition
because Flex has already removed the components.

I've worked it out. You can specify when the component removal
happens by using a mx:RemoveChildAction tag:

@font-face {
src: local(Arial);
fontFamily: myArial;
}
global {
fontFamily: myArial;
fontSize: 15
}
/mx:Style

mx:Transition fromState= toState=A
mx:Sequence target={lblMessage} duration=2000
mx:Glow alphaFrom=1 alphaTo=0 /

mx:Sequence target={lblMessage} duration=2000
mx:Fade alphaFrom=1 alphaTo=0/
mx:RemoveChildAction/
/mx:Sequence
/mx:Transition

(Note: I've also embedded a font to allow the Fade effect to work
properly)
[flexcoders] Data Binding and dealing with NULLs
I hit this problem quite often and wonder if there is a general
solution...
I have a component which displays a list of questions and has the
concept of a current question i.e. the question the user is answering:
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
public var questions:ArrayCollection;
[Bindable]
public var currentQuestion:MultipleChoiceQuestion =
questions[lstBox.selectedIndex];
]]
/mx:Script
The problem is that the questions array doesn't get populated until
after Flex has tried to setup all the bindings meaning I get a
NullPointer when it tries to setup currentQuestion.
At the moment I have to get around this with the following code:
!-- Databinding of Current Question --
mx:Script
![CDATA[
private function init():void {
refreshCurrentQuestion();
}
public function refreshCurrentQuestion():void {
if (questions != null) {
currentQuestion =
questions[lst.selectedIndex];
}
}
]]
/mx:Script
This seems quite hacky...

mx:DataGridColumn itemRenderer=MyCustomComponent
dataField=startDate/
mx:DataGridColumn itemRenderer=MyCustomComponent dataField=endDate/
In this case the component MyCustomComponent would know to look at the
data.startDate field when displaying the first column and the
data.endDate field when displaying the second column. I would imagine
the component to look something like:
mx:Label text={formatter.format(data[dataField])}/
[flexcoders] Re: Accessing dataField from within a Custom Item Renderer
Thanks for the response (I can't believe how hard it's been trying to
find this out!). I'm trying to use the following component in a
DataGrid, but listData is evaluating to NULL when I debug the
application:
?xml version=1.0 encoding=utf-8?
mx:Label xmlns:mx=http://www.adobe.com/2006/mxml; textAlign=center
mx:Script
![CDATA[
import mx.controls.dataGridClasses.DataGridListData;
private function getData():Object {
var columnMetadata:DataGridListData =
DataGridListData(listData)
var fieldName:String =
columnMetadata.dataField;
return data[fieldName];
}
private function getFormattedDate():String {
return df.format(getData());
}
]]
/mx:Script
mx:DateFormatter id=df formatString=DD-MMM-YY/
mx:Label text={getFormattedDate()}/
/mx:Label
Am I being dense?

Yes, you'll want to look into the listData property. Flex
automatically populates it for drop-in editors and renderers, so if
your renderer implements IDropInListItemRenderer or inherits from a
class that does (Button, Label, ComboBox, plus 11 more) then you will
be able to access listData. When your renderer is in a DataGrid,
listData will be of type DataGridListData, which provides properties
like dataField, columnIndex, rowIndex, etc.

Yup...I was being dense:

[flexcoders] Progress Bar Item Renderer
I'm trying to create a progress bar item renderer, but I can't get the
value of progress bar to bind:
mx:AdvancedDataGridColumn headerText=% Complete width=100
mx:itemRenderer
mx:Component
mx:VBox
mx:Label id=lbl
text={data.percentageComplete}/
mx:ProgressBar label=%3%% maximum=100
width=100%
mode=manual source={data.percentageComplete}/
/mx:VBox
/mx:Component
/mx:itemRenderer
/mx:AdvancedDataGridColumn
You don't appear to be able to bind the value using source. What am I
doing wrong?
[flexcoders] Re: Progress Bar Item Renderer
When using 'manual' you could try using the setter method, again
from the docs...
I've tried doing this but Flex doesn't like having script blocks in
the item renderer.
When needed for binding, take a look at BindingUtils.bindSetter
I don't know what to do with this as I can't get into a SCRIPT block.
A small example would really help.
Cheers,
David.

The source-property is bindable, though as stated in the docs:
Refers to the control that the ProgressBar is measuring the progress
of. Use this property only in event and polled mode. A typical usage
is to set this property to a Loader control.
Since you set your mode to manual, the source-property will be ignored
and as a consequence, the binding won't be executed.
When using 'manual' you could try using the setter method, again from
the docs:
public function setProgress(value:Number, total:Number):void
Sets the state of the bar to reflect the amount of progress made
when using manual mode. The value argument is assigned to the value
property and the maximum argument is assigned to the maximum property.
The minimum property is not altered.
When needed for binding, take a look at BindingUtils.bindSetter

[flexcoders] Re: Progress Bar Item Renderer
hmmm... the code completion in Eclipse builder says it isn't valid,
but the compiler says it is
Anyway, I solved the problem by creating a new class:
?xml version=1.0 encoding=utf-8?
mx:HBox xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Script
![CDATA[
import mx.controls.ProgressBarLabelPlacement;
import mx.controls.ProgressBarMode;
import mx.controls.ProgressBar;
private var _data:Object;
override public function set data(value:Object):void {
_data = value;
var percentageComplete:Number =
Number(value.percentageComplete) *
100;
var colour:Number
if (percentageComplete == 0)
{
colour = 0xda0707;
}
else if (percentageComplete == 100)
{
colour = 0x04ae30;
}
else
{
colour = 0x005efb;
}
removeAllChildren();
var pb:ProgressBar = new ProgressBar();
pb.mode = ProgressBarMode.MANUAL;
pb.label = %3%%
pb.setStyle(barColor, colour);
pb.labelPlacement =
ProgressBarLabelPlacement.CENTER;
pb.setProgress(percentageComplete, 100);
pb.percentWidth = 100;
addChild(pb);
}
override public function get data():Object {
return _data;
}
]]
/mx:Script
/mx:HBox

Seems to me that Flex doesn't like scripts anywhere but in the

a document. I do not have any experience with item-renderers, nor do I
have with loaders, but this is my guess:
If you create the ItemRenderer as a custom mxml-component, then you
should be able to set a script-block in this file.
Again this is just my wild thinking, but I hope that with it, you, or
others in here, might get to a working example.
Good luck,

[flexcoders] Re: Displaying an image stored in a database
If you're getting it through an object-serialization framework (AMF, etc.), Yup, that's what I'm doing. then you may be receiving it already as a ByteArray, in which case you need to load it with a Loader instance. Where could I find information about this? I've found the flex documentation on these back-end/front-end integration issues rather thin on the ground. Cheers, David. --- In flexcoders@yahoogroups.com, Troy Gilbert [EMAIL PROTECTED] wrote: When the employee objects are sent back to the client I don't know how to bind to this property as mx:Image source=.../ takes the *location* of the image, not the binaries themselves. Depends on how the data (or what format) its arriving in to your Flex app. If it comes over the wire in an XML doc (like a BASE64 encoded BLOB from a database), then you'll need to turn that into a ByteArray (I believe AS3 corelib, from Adobe -- see Google code -- has API for this), then load the ByteArray (assuming its the bytes of a PNG/JPG/GIF/SWF) with the Loader class. If you're getting it through an object-serialization framework (AMF, etc.), then you may be receiving it already as a ByteArray, in which case you need to load it with a Loader instance. Note, when using Loader, if you have it load bytes from a ByteArray there is still a one-frame delay before the loader completes, i.e. you do have to wait for it to fire the COMPLETE event before the content is accessible.
