The name of a field in the original record

A string, enclosed in single quotes ('), that contains a mix of text and tags. A tag is the name of
a field in the original array, enclosed in < and >.

For example, suppose you want to assign an array to the
component using data binding. The objects within the array do not have a
(which the list uses if available). You could use this formatter to create a new array through data
binding that replicates the objects within your original array and adds a
object using the values you define. The following template would achieve this (this would be on a
binding between your array and the List component's
label='My name is <firstName> <lastName>;'
firstName=firstName;
lastName=lastName;
This syntax assumes that the object has two properties, called

Note: This formatter can be used on any binding from a component property that is of the Array type
to another component property of the Array type. Also note that the Rearrange Fields formatter
doesn't work if you access if in the Schema panel, but does work if you access it in the Bindings
panel.

You can create custom formatters. The number of formatters allowed is unlimited. Formatters are
defined by XML files found in the Flash MX Professional 2004 Configuration/Formatters folder.
The definition includes the following metadata:

Schema data types
A data type is an object that represents all the runtime logic needed to support a particular data
type. A data type can be a scalar type, such as integer, string, date, currency amount, or ZIP code.
It can also be a complex type, with subfields and so on. A data type can test a data value to
determine if it is valid for that data type. The following data types come with Flash MX
Professional 2004:
Array
