example code |
Page number is from the rough cuts pdf. 2007/04/15 version.
Broken example. Code Fragment below...
<project name="FlexTest" default="run" basedir="./">
...
<target name="intialize">
<mkdir dir="${deployDirectory}" />
</target>
<target name="compile" depends="initialize">
...
</project>
Spelling mistake "intialize" should read "initialize".

Last sentence/code fragment |
The last parameter to button.removeEventListener() "onClick" should really be "clickHandler" to reflect
the code snippet above (since the text mentions that the parameters for both calls must be identical.

Last line of section 4.7 |
The last part of section 4.7 reads as follows:
----
The following example removes the event listener added in the previous example:
button.removeEventListener(MouseEvent.CLICK, onClick);
----
However, in the "previous example" as far as I can tell, there was no event "onClick" registered:
---
button.addEventListener(MouseEvent.CLICK, clickHandler);
---
The proper name of the event that should be unregistered is "clickHandler" in this example -- if I'm
understanding what I'm reading.

Code samle under "Using PopUpButton" |
I am using the Flex Builder 2.0.1 tool in Eclipse 3.2.2 and using the snipit of code included in the book
on page 141 under the "Using PopUpButton" section:
...
var xmlList:XMLList = <items>
<item label="ActionScript"/>
<item label="Class"/>
<item label="Interface"/>
</item>
<item label="MXML">
<item label="Application"/>
<item label="Component"/>
</item>
</items>;
...
Gives me the following error:
"Implicit coercion of a value of type XML to an unrelated type XMLList."
After digging around I found that I had to actually create a new XMLList object using the XML as the
parameter being passed in. Like so:
var xmlList:XMLList = new XMLList(<items>
<item label="ActionScript"/>
<item label="Class"/>
<item label="Interface"/>
</item>
<item label="MXML">
<item label="Application"/>
<item label="Component"/>
</item>
</items>);
I suspect this might be the case for any page that tries to create a var of type XMLList using the XML
directly instead of instantiating a new object. (Up until this point I have been creating my collections
using ActionScript). Maybe the first syntax is correct when compiling by hand, but Flex Builder doesn't
auto-compile unless I create the new XMLList object =(

A sentence reads, "Therefore, changing a value in a numeric stepper used as an item renderer will not
affect the data provider, whereas it will update the data provider when used as an item renderer." It
seems as though the second "item renderer" should read "item editor" - but with this interpretation, the
"However" in the beginning of the next sentence doesn't seem to make sense.
[187/188] Example 8-17;
Does not work right, keyUpHandler generates errors 1023 and 1024.
Changing the name of the function made it work...

4th paragraph |
In the following code, a SWF library item is used as a button icon:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" initialize="init()">
<mx:Button label="Click me" source="@Embed(source='assets/library.swf', symbol='circleAnimation')"/>
</mx:Application>
The first instance of the word "source" should be changed to "icon".
Corrected Example Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" initialize="init()">
<mx:Button label="Click me" icon="@Embed(source='assets/library.swf', symbol='circleAnimation')"/>
</mx:Application>

public static function parseFromXML |
"xml.@Itemname" should be "xml.@name"
"xml.@itemName does not match what is in the XML file
Also, in the XML file, the last checkbox uses "itemName" instead of name, and the value should be
something besides "city"

Example 11-11, import statement line 3 and function initInstace parameters |
Hi there,
i guess there's a little typo in the mentioned locations on page 250. The "mx.effects.EffectInstance"
class is imported and used as datatype for the parameter of initInstance. But, in my opinion, it has to
be the "mx.effects.IEffectInstance" interface in both places, because otherwise the override of
initInstance is not allowed.

The text claims that "Type selectors always take precedence over class selectors." However, the reverse
is true, as shown in example 14-2.

Missing class com.oreilly.programmingflex.lso.ui.LogInForm.as |
I think a class com.oreilly.programmingflex.lso.ui.LogInForm.as referenced by the Main mxml class in the
login example is missing. I neithe rfind it in the book nor in the associated files. If possible, please
publish this class, because otherwise, the example code does not compile, thanks!

The example subclasses UIComponent. When I subclass UIComponent, nothing displays. If I subclass a
container like Canvas without changing any other code, the contents display.
