Isis currently requires annotations to be on the getter, not on the field;
see for example [1]. Are those annotations you've listed on the field ?
If so, that'll be the issue.
Also, the (Isis) @Optional annotation is not required if you have the (JDO)
annotation @javax.jdo.annotations.Column(allowsNull = "true").
Let me know if that fixes things or not.

Hi Dan,
I used the annatation the way you described it:
� ��private String middleName;
�� �
� � @Named("tussen")
� � @javax.jdo.annotations.Column(allowsNull = "true")
� � @MemberOrder(sequence = "2")
� � public String getMiddleName() {
� � � � return middleName;
� � }
�� �
� � public void setMiddleName(String name) {
� � � � this.middleName = name;
� � } � �
In the console you can see that it is picked up correctly:
(
� � "id" BIGINT GENERATED BY DEFAULT AS IDENTITY,
� � "dateOfBirth" DATE NOT NULL,
� � "firstName" NVARCHAR(255) NOT NULL,
� � "joinedOn" BLOB NOT NULL,
� � "lastName" NVARCHAR(255) NOT NULL,
� � "middleName" NVARCHAR(255) NULL,
� � "sex" NVARCHAR(255) NOT NULL,
� � "version" BIGINT NOT NULL,
� � CONSTRAINT "User_PK" PRIMARY KEY ("id")
)
But in the user-interface it remains required. (see attachtment) [1]
