Bit #38 - Creating a custom ADF Faces client-side converter

You can create a custom ADF Faces client-side converter by ensuring that your converter class implements the org.apache.myfaces.trinidad.convert.ClientConverter interface. This is done in addition to implementing the javax.faces.convert.Converter interface, which implements the custom converter on the server. To implement the ClientConverter interface you need to provide implementation for the getClientConversion() and getClientScript() methods. The getClientConversion() implementation should return the JavaScript constructor of the client converter. The getClientScript() implementation on the other hand should return the actual JavaScript code that implements the client converter.


public class CustomConverter implements javax.faces.convert.Converter,
                             org.apache.myfaces.trinidad.convert.ClientConverter {
    // implement the javax.faces.convert.Converter interface for server-side conversion
    // implement the org.apache.myfaces.trinidad.convert.ClientConverter interface for
    // client-side conversion

    // return the JavaScript client converter
    public String getClientConversion(FacesContext context, UIComponent component) {
        return "new CustomConverter()";

    // return the actual client converter JavaScript code
    public String getClientScript(FacesContext context, UIComponent component) {
        return null;

For a complete implementation of an ADF Faces client converter take a look at this reference from an older Oracle documentation: Unfortunately, this example is not part of the latest documentation.
