Boolean: This Data Type contains the value null. This value means no value :P
Which basically means there is no data. You can use the Null value in a variety of ways to point out that a property or variable does not have an certain value assigned to it. The Null data type is the " default " data type for all the classes that classify ( define ) complex data types. The one exception to this important rule is the " Object class ", which defaults to undefined!
Here is an example of Boolean Data in a form field:
if (Selection.getFocus() == null) { trace("no selection" }
