Problem With Custom Property Editor

[nyuby]

I'm new comer on swf. I try to use custom property editor but not success yet.
I have a entity BorrowingBook with two field have a Date property. I try to use propertyEditorRegistrar in my flow config look like this :

 <bean id="borrowBookAction" class="org.springframework.webflow.action.FormAction">
        <property name="formObjectClass" value="org.kris.entity.BorrowingRecord"/>
        <property name="propertyEditorRegistrar" value="org.test.util.PropertyEditors"/>
    </bean>

And this is my PropertyEditors implementation :

public class PropertyEditors implements PropertyEditorRegistrar{

    public void registerCustomEditors(PropertyEditorRegistry registry) {
        SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-mm-dd");
        dateFormat.setLenient(false);
        registry.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
    }
}

This class entity :

@Entity
public class BorrowingRecord implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String isbn;
    @Temporal(javax.persistence.TemporalType.DATE)
    private Date borrowDate;
    @Temporal(javax.persistence.TemporalType.DATE)
    private Date returnDate;
    private String reader;

but if i try to run this code i getting error look like this :

Caused by: java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [org.springframework.beans.PropertyEditorRegistrar] for property 'propertyEditorRegistrar': no matching editors or conversion strategy found

I don't know how to use it with proper value with my entity class property. How to use property editor for spesific value ?
Is there another way to use it ?

Thanks lot before...
