Error saving Entity with @Embedded field

Generate an embeddable class (Parts.java) using Spring Roo and adding as field on another class (Product.java)

@RooJavaBean
@RooToString
@Embeddable
public class Parts {

    /**
     */
    private String part1Name;

    /**
     */
    private String part2Name;

    /**
     */
    private String part3Name;
}

@RooJavaBean
@RooToString
@RooJpaActiveRecord
public class Product {

    /**
     */
    private String productName;

    /**
     */
    @Embedded
    private Parts parts;
}

When generates web layer using Roo Commands, Embedded field is generated as input field and is not able to save Product entity.

To solve this, is necessary to generate a Conversor when generates web layer and add a individual input field to every embeddable class fields.

Attached generated source using ROO commands and modified source with solution implementation.
