I created a Spring Boot, DATA Rest, Hibernate application.

I added to my bean a @ScriptAssert and it works fine but unfortunately differently from other validators it return an object as invalid value.

This is my bean:

public class DocumentRow extends AbstractEntity {

    @ManyToOne(fetch = FetchType.LAZY, optional = false)

    private Document document;



    @JsonDeserialize(using = ProductUriDeserializer.class)

    @Any(fetch = FetchType.EAGER, metaDef = "ProductDocumentRowDef", metaColumn = @Column(name = "productGroup"), optional = true)

    @AnyMetaDef(name = "ProductDocumentRowDef", metaType = "string", idType = "long", metaValues = {@MetaValue(value = "OL", targetEntity = OphthalmicLens.class),

            @MetaValue(value = "F", targetEntity = Frame.class), @MetaValue(value = "CL", targetEntity = ContactLens.class)})

    @JoinColumn(name = "product_id")

    private Product product;



    // The description of the product/note

    @Size(max = 255)

    @NotBlank

    @Column(nullable = false)

    private String description;



    // Reference to another document row (order/ddt/)



    @NotNull

    @Min(1)

    @Column(nullable = false)

    private int qty = 1;



    // taxable amount (without taxes)

    @NotNull //    @Min(value = 0)

    @Column(nullable = false, scale = 2)

    private BigDecimal unitPrice = BigDecimal.ZERO;



    // discount on taxable amount

    @NotNull

    @Min(value = 0)

    @Max(value = 99)

    @Column(nullable = false, scale = 2)

    private BigDecimal percentageDiscount = BigDecimal.ZERO;



    // (unit price * qty) - percentageDiscount% on that amount

    @NotNull

    @Min(value = 0)

    @Column(nullable = false, scale = 2)

    private BigDecimal amount = BigDecimal.ZERO;



    @JsonDeserialize(using = TaxRateUriDeserializer.class)

    @ManyToOne(fetch = FetchType.EAGER, optional = true)

    private TaxRate taxRate;



    // The total amount of taxes on taxable amount (unit price - percentageDiscount%) * qty)

    @NotNull

    @Min(value = 0)

    @Column(nullable = false, scale = 2)

    private BigDecimal taxAmount = BigDecimal.ZERO;



    // Total amount (amount+taxAmount)

    @Formula(value = "amount+taxAmount")

    private BigDecimal totalAmount;



    //says if the row is a note

    @NotNull

    @Column(nullable = false, columnDefinition = "BIT DEFAULT 0")

    private boolean note = false;

and this is TaxRate:

public class TaxRate extends AbstractEntity {



    @NotBlank

    @Column(nullable = false)

    private String name;



    @NotBlank

    @Column(nullable = false, unique = true)

    private String code;



    @NotNull

    @Min(value = 0)

    @Max(value = 99)

    @Column(nullable = false, scale = 2)

    private BigDecimal rate;



    @Enumerated(EnumType.STRING)

    private TaxType type;



    @NotNull

    @Column(nullable = false, columnDefinition = "BIT DEFAULT 0")

    private boolean preset = false;

This is the @ScriptAssert:

@ScriptAssert(lang = "javascript", script = "_.note==false?_.taxRate!=null:true", alias = "_", reportOn = "taxRate", message = "{documentrow.taxrate.mandatory}")

and this is the response I got from my rest controller:

{

  "errors" : [ {

    "entity" : "test.server.model.accounting.documents.DocumentRow",

    "property" : "taxRate",

    "invalidValue" : "test.server.model.accounting.documents.DocumentRow@95104f01",

    "message" : "{documentrow.taxrate.mandatory}"

  } ]

}

How you can see the invalidValue is DocumentRow itself, instead it should be TaxRate.
How can I customize the invalidValue returned from ScriptAssert?
