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 Chapter 3, “Flex Classes,” on page 41.

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

 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

For more information on changes to the supported color value formats, see “Using colors”

on page 121.
