There are several ways to define the schema for a component. Here are the most common ways:
•
For an XMLConnector component, you can import an XML sample file to define the schema.
See "Connecting to XML data with the XMLConnector component (Flash Professional only)"
on page 277.
•
For a WebServiceConnector component, you can import the WSDL for a web service to
define the schema. See
component (Flash Professional only)" on page
•
For a DataSet component, which is typically the intermediary component between your
connector components and UI components, you define the schema using the Schema panel.

•
For UI components, the schema is predefined within the component. You can modify the
schema to create additional bindable properties, as shown in

Adding a component property to a schema
You typically add component properties to a schema for the following reasons:
•
To make an existing component property bindable. You can make any component property
bindable if you add it to the schema.
•
To define the fields of a DataSet component to describe expected data fields. Most commonly,
you need to define the data type for an expected field, but there are numerous other properties
you can set. For more information, see the examples in
"Schema item settings" on page
The following example illustrates how you make an existing component property bindable by
adding the component property to the component's schema. In the example, you create an
application that uses a CheckBox component to indicate whether a TextInput component is
editable. Because the TextInput component's schema does not initially contain the
property, you add the
