Returns
Nothing
Description
Property; a reference to a user-defined function that is invoked if ActionScript code refers to an
undefined property or method. If ActionScript code refers to an undefined property or method of
an object, Flash Player determines whether the object's
is defined, the function to which it refers is executed and passed the name of the
__resolve
undefined property or method. This lets you programmatically supply values for undefined
properties and statements for undefined methods and make it seem as if the properties or
methods are actually defined.
This property is useful for enabling highly transparent client/server communication, and is the
recommended way of invoking server-side methods.
