These two categories of the Palette contain standard JavaServerTM Faces validators and converters.
java.lang.String
values in
your component properties and a Java data type.You usually do not need to add a converter to a component property. An appropriate converter is automatically added to the appropriate property of a component when you bind the component to a database table or other source of data. However, you can override the default converter.
Typically, the way you add a validator or converter
to a JavaServer Faces component is to edit the component's validator
or converter
property, which provides drop down lists from which you can select a validator
or converter.
