Converts between java.lang.String values in your component properties
and data types of java.math.BigInteger. The converter is usually applied to the component property that is used to display values and to pick up values entered by users, such as the text property of a Text Field component.
An example is binding a JavaServer Faces component to an Oracle database column
of type NUMBER. When you bind a component, the IDE normally identifies
the data type for you and sets the appropriate converter when you establish
a binding to the value property. However, you can also add this converter
manually by setting the component's converter property.
Conversion error occurred.
name: 'entered-value' must be a converter-type.
In this message, name is either the ID of the component or the contents of its label if the component has one, entered-value is the value that the user entered, and converter-type is the type of the converter. For example, if the converter is a Big Decimal converter, the converter-type is signed decimal number.
