[flexcoders] Re: Select row in Advanced Data Gridprogrammatically for unit test

[bobignacio]

Try this...

Given:

1. The grid's dataProvider is bound to a bindable var named "dp"
[Bindable] private var dp:ArrayCollection;

2. A DataGrid with an id="grid"...
 -1) {
 grid.dispatchEvent(new ListEvent(ListEvent.ITEM_CLICK));
}

// Ensure that the row is highlighted and displayed
grid.verticalScrollPosition = grid.selectedIndex;

Hope this helps...

[flexcoders] Re: Looking for ideas

[bobignacio]

Why not use 2 list boxes side by side and drag and drop between the 2?
One being the total list of tasks and the other the sequence to
create/follow. The user can then make modifications visually with both
lists.

You can always use the following in your mxml file...

Have you read up on the Cairngorm Microarchitecture?
You may want to consider using this framework cuz
what you are describing will handle that use case...
updating multiple views when your data model changes.
Here is the main page...there is also information in Adobe Labs as

[flexcoders] Re: RichTextEditor - format preservation

[bobignacio]

Hi there,

Snippet of your code...

[Bindable]
public var contents:String = "";

private function handleChange(event:Event): void {

 contents = editor.htmlText;

 // My Debug
 trace("Change Fired and Caught");
 trace("Contents: " + contents);
 trace("Editor Updated: " + editor.htmlText + "\n");
}

Change the following:



to this:



This resolves your issue that you mention.
If you follow the debug with your original code for the editor,
you will find that since you have the "htmlText" attribute in the
editor set to your Bindable variable "contents" you are unnecessarily
updating the editor's "htmlText." This is causing your issue.

With every keystroke, the editor is already updating
its htmlText automatically so the Bindable "contents" is
probably clobbering your editor's automated update.

Hope this helps,

Bob I.

I read up on eapps.com hosting. The user guides they provide are the

[flexcoders] Re: internet explorer problem

[bobignacio]

Hi there,

I see 2 possibilities...

First...

Take a look at Photoshow.mxml. I don't see where your pictures array
is initialized as in "pictures = new Array();" When the swf is loaded
into the browser, your pictures array is still null. It is possible
that IE just has a problem with that while the others don't.

  //all the pictures
  private var pictures:Array;

  //this changes the set of pictures
  public function set dataProvider(value:Array):void {
   pictures = value;
   currentIndex = 0;
   updateCurrentPicture();
  }


Second...I feel better about this possibility...

Try the edits below in your XMLPhotoshow.mxml:

// Set pictures as Bindable
[Bindable] public var pictures:Array;

public function set xmlSource(xml:XML):void {

  var index:int = 0;
  pictures = new Array();

  //var pictures:Array = new Array();

  for each( var image:XML in xml..image ) {
   pictures[index] = new PhotoshowImage();
   pictures[index].name = image.itemName;
   pictures[index].caption = image.itemCaption;
   pictures[index].width = image.itemWidth;
   pictures[index].height = image.itemHeight;
   index++; 
  }

  // photoshowContainer.dataProvider = pictures;
}

[bobignacio]

Hey Jay,

When looking at the WSDL from weather.gov:

 http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl

These are the following sections of the WSDL which is posted which you
are attempting to use:


 
 
 
 
 



 


In your flex application, reexamine that the method name is spelled
correctly (NDFDgenByDay),  all of your arguments are spelled correctly

Posting a snippet of your code may help as well.

Hi All,

I haven't had any trouble formatting the datatips in a PlotChart using

Is there any thing like a label such as in the PieChart for Cartesian

[flexcoders] Re: Storing / retrieving rich text

[bobignacio]

I originally posted this on Adobe's web site back in Nov/06...

Title: Sending a ByteArray of rich text to a Java Web Service via
WebService component.

Topic: Keeping the rich text (HTML formatted string) intact

I was able to send and receive rich text (HTML formatted txt) intact
via a Java web service using Weblogic 9.2. Creating a web service in
Weblogic 8.1 is more difficult so I opted for this route. Regardless
what back end implementation you are using, in order to keep rich text
intact is to send it via a ByteArray in flex. And with the web service
(possibly using Coldfusion), be sure that the input parameter and
return types that the WSDL creates are "base64Binary."

Creating a web service in Weblogic 9.2 is pretty easy. If you are
using this app server then the 9.2 docs on Web Services is how I
created my back end. My web service simply accepts a byte[] as a
parameter and returns it.

public class HelloWorldImpl {

 public byte[] getBytes(byte[] bAry) {
  return bAry;
 }
}

In flex:

[Bindable] private var bAryObj:ByteArray = new ByteArray();
[Bindable] private var txtResult:String;

public function sendingBytes(event:Event) {

 // inputTxt is a HTML formatted string a.k.a rich text
 bAryObj.writeUTF(inputTxt);

 // call webService
 wsData.getBytes.send();
}

public function webSvcHandler(event:ResultEvent) {

 var b:ByteArray = new ByteArray();
 b.position = 0; // make sure you read the array from the beginning

 // use binding of txtResult in some component as {txtResult}
 txtResult = b.readUTF() as String;
}

mxml - be sure mxml parameter names match exactly the web service
parameter names:



{bAryObj}




I used a Button component to call sendingBytes() via the click event.

Hope I didn't forget anything...and hope this helps.

Bob I.

[flexcoders] Re: Need help seaching and comparing in an ArrayCollection

[bobignacio]

flex 2 provides a more efficient way of manipulating an
ArrayCollection using a "filterFunction" from the IViewCollection
Interface. This also provides the use of a cursor which you can use to
manipulate the collection as well. Sorting is first required if you
want to use a cursor. Filtering can be done in a 1 line conditional
stmt which eliminates any need to loop through the entire
ArrayCollection. Look in Chap 7., pg 161 of the Developer's Guide with
a very good example on pg. 178 and 185.

Hope this helps,

Bob I.

[flexcoders] Re: ArrayCollection.filterFunction assigned but returns null

[bobignacio]

I just recently dealt with the filterFunction and had a struggle with
it as well. Let's say for example:

/*
 * Filter for a first name
 *
 * @param collectionObj the entire ArrayCollection/XMLListCollection
 */
private function firstNameFilter(collectionObj:Object):Boolean {
 return obj.id == 'Bob';
}

In my case, I remember having a fairly complicated return condition
where it actually didn't return a Boolean but an Object by accident.
The "collectionObj" is actually the entire ArrayCollection which is
compared to your return statement and if an element qualifies, it will
return true for each element in the List. However, if the condition is
not returning a Boolean but an Object, you may just get a null. And
even if the filterFunction returns null, the dataProvider in your
datagrid may just be displaying the data cuz the condition was never
returning a Boolean in the first place which may be what is happening.

I ended up putting a trace statment inside the filterFunction to
actually examine the collectionObj and I found that I was returning an
Object and not a Boolean value.

Hope this helps...

Any chance to post your source code?

[flexcoders] Re: Return of single object from ColdFusion

[bobignacio]

You can always try the following:

 thisPerson = (Employee)(event.result);

However, you may get the error of "cannot convert Object to Employee.
But its worth a try.

[flexcoders] Re: Accesing complex structures in result from WebServices

[bobignacio]

Thanks for the quick response!

Can we set up types like Image, VideoDisplay and RichText within a
complex object and send that to a WebService?

My main fear is that the "source" property will just send over a
String to the web service vs. the actual binary file.

Something along the lines appending to your example:

var args:Object = new Object();
args.foo = new Object();
foo.image = new Image();
foo.image.source = "someDirectory/image.jpg";
foo.video = new VideoDisplay();
foo.video.source = "someDirectory/video.flv";
foo.editor = new RichTextEditor();

foo.editor.htmlText = "HTML Formatted
TextThis
paragraph contains bold, italic, underlined, and
bold italic underlined
text.This a red underlined 14-point arial font
with no alignment set.This a teal bold 12-pt.
Verdana font with alignment set to right.";

Thanks again!

Hi Leo,

I have recently been playing with the flex WebService stuff...How did
you send a complex structure _from_ flex to your Web Service?

Thanks,

Bob
