Step 1: Find and replace

11

This section describes only the most common targets of finding and replacing. There are 
many other members of Flex classes that have changed that are not mentioned here. For a 
complete list, see 

Application namespace

Change the MXML namespace. Change the following:

xmlns:mx="http://www.macromedia.com/2003/mxml"

to this:

xmlns:mx="http://www.adobe.com/2006/mxml"

For example:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

Void

Replace 

Void

 (with a capital V) with 

void

 (with a lower-case v).

Newline

The 

newline

 constant has been removed. In ActionScript, use “\n” to add a carriage return in 

your Strings. In an MXML tag, use the 

&#13;

 XML character entity to add a carriage return.

Color value formats

Replace all occurrences of 0x with # in CSS style sheets or 

<mx:Style>

 tag blocks. The 

supported color value formats have changed; for example:

.b1 { color: red; }

// Valid

.b2 { color: #FF0000; }

// Valid

.b3 { color: 0xFF0000; }

// Invalid

In calls to the 

setStyle()

 method, you can prefix RRGGBB color values with 0x or #, but 

you must put quotation marks around constants and # values; for example:

b1.setStyle("color",0xFF0000);

// Valid

b2.setStyle("color","red");

// Valid

b3.setStyle("color","#FF0000");

// Valid

b4.setStyle("color",red);

// Invalid

b5.setStyle("color",#FF0000);

// Invalid
