SevenSixRenderer class

Sorry my bad on the previous comment regarding creating a custom Item
Renderer chapter 7.9 Flex 3 Cookbook.
It should actually be changed from this:
var _imgClass:Class = UIComponent(owner).document[ listData.label];

to this:
_imgClass = UIComponent(owner).document[ listData.label];

as the _imgClass variable has already been declared at the top of the class.

Gomen yo :)
cheers

Chapter 11.13.3 error
In the Discussion section of this chapter, after the :

-

AddChild
-

RemoveChild
-

SetEventHandler
-

SetProperty
-

SetStyle

there is this reference/tip:

(For more information on the IOverride interface, see Recipe 11.15.)


That probably should be ...see Recipe 11.14.)
since there is no 11.15!

Note from the Author or Editor:
change to:

(For more information on the IOverride interface, see Recipe 11.14.)

14.9.3
Full code view of the Properties class

Having gone through this solution, I found that there was an issue with the wrapping of the EventDispatcher.

When binding an array collection of my dynamic objects to a datagrid, I found that when a sort was automatically applied to the datagrid after a binding update, an error was often thrown by Sort.as.

mx.collections.Sort.findItem() was being passed in the parameter

Note from the Author or Editor:
should be changed to:

public function Properties() {
_evtDispatcher = new EventDispatcher(this);
}

First sentence under the Discussion heading

The first sentence starts:
"To define an optional method or multiple optional methods for a method,"

This obviously should be:
"To define an optional parameter or multiple optional parameters for a method,"

Note from the Author or Editor:
Page number of error:
33

change
"To define an optional method or multiple optional methods for a method,"
to
"To define an optional parameter or multiple optional parameters for a method,"

In the Flex 3 Cookbook , Printing May 2008 First Edition,



I found an error:



[157] var menu:ContentMenu=new ContextMenu();



I think it must be

var menu:ContextMenu=new ContextMenu();

Code listing

The line

public class CenteredCheckBoxHeaderRenderer extends CenteredCheckBox


should read


public class CenteredCheckBoxHeaderRenderer extends CheckBox


I don't know how this got in there.

PHP code, lines 1 and 2

the first two lines of the PHP code are incorrect. The $_FILES variable passed into PHP is called "Filedata" by default and in the example Flex code.

So,

INCORRECT
$file_temp=$_FILES['file']['tmp_name'];
$file_name=$_FILES['file']['name'];

should be replaced with

CORRECT
$file_temp=$_FILES['Filedata']['tmp_name'];
$file_name=$_FILES['Filedata']['name'];

This has been tested and works.

Note from the Author or Editor:
$file_temp=$_FILES['Filedata']['tmp_name'];
$file_name=$_FILES['Filedata']['name'];

3rd paragraph

In section 11.3 (re: AddChild- and RemoveChild actions in transitions), the 3rd paragraph currently reads:

Note from the Author or Editor:
Should read:

'Note that the RemoveChildAction tag controls when the child is removed, but it does not remove the child. The RemoveChildAction mechanism doesn't call its remove method automatically. To remove the child...'

Method .getParent()


In the above method, the expression:

if(obj.parentTask == node.parentTask)

should be

if (obj.parentTask == node.id)

Note from the Author or Editor:
should read:


if (obj.parentTask == node.id)

At the bottom of the page is the following PHP code snippet:

<?php
$id_number = $_GET["id"];

This should read:

<?php
$id_number = $_POST["id"];
