Bean Validation ScriptAssert funktioniert nicht

Question

Ich bin mir nicht sicher, ob ScriptAssert auf Field angewendet werden kann. Ich versuche die folgende ScriptAssert aber die ganze Zeit gibt es die Nachricht "Wert ist obligatorisch" sogar die _this.OBJSTATE! = 'CANCELED'. Kann mir bitte jemand helfen ??

<?xml version="1.0" encoding="UTF-8"?> 
<constraint-mappings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:schemaLocation="http://jboss.org/xml/ns/javax/validation/mapping validation-mapping-1.0.xsd" 
        xmlns="http://jboss.org/xml/ns/javax/validation/mapping"> 
    <default-package>x.x</default-package> 

    <bean class="x.class" ignore-annotations="true"> 
     <field name="OBJSTATE"> 
      <constraint annotation="javax.validation.constraints.Pattern"> 
       <message>Value should be CANCELLED/RELEASED</message> 
       <element name="regexp">^(CANCELLED)$|^(RELEASED)$</element> 
      </constraint> 
      <constraint annotation="javax.validation.constraints.NotNull"> 
       <message>Field is Mandatory</message> 
      </constraint> 
      <constraint annotation="org.hibernate.validator.constraints.NotBlank"> 
       <message>Value is Mandatory</message> 
      </constraint> 
     </field> 
     <field name="T1PONumber"> 
      <constraint annotation="org.hibernate.validator.constraints.ScriptAssert" > 
       <message>Value is Mandatory</message> 
       <element name="lang">javascript</element> 
       <element name="script" > 
        <value>_this.OBJSTATE == 'CANCELLED'</value> 
       </element> 
      </constraint> 

     </field> 

    </bean> 
</constraint-mappings>

ScriptAssert sollte

<bean class="x.class" ignore-annotations="true"> 
    <class ignore-annotations="false" > 
     <constraint annotation="org.hibernate.validator.constraints.ScriptAssert"> 
      <message>T1PONumber value is Mandatory</message> 
     <element name="lang">javascript</element> 
     <element name="script" > 
      <value>_this.OBJSTATE != 'CANCELLED'</value> 
     </element> 
     </constraint> 
    </class> 
    <field name="OBJSTATE"> 
     <constraint annotation="javax.validation.constraints.Pattern"> 
      <message>Value should be CANCELLED/RELEASED</message> 
      <element name="regexp">^(CANCELLED)$|^(RELEASED)$</element> 
     </constraint> 
     <constraint annotation="javax.validation.constraints.NotNull"> 
      <message>Field is Mandatory</message> 
     </constraint> 
     <constraint annotation="org.hibernate.validator.constraints.NotBlank"> 
      <message>Value is Mandatory</message> 
     </constraint> 
    </field> 
    <field name="T1PONumber"> 


    </field> 

</bean> 

auf Klassenebene angewendet werden
