optional field (property)?

Hi,


	�

	I am just starting with Isis.

	I want a field (property) to be optional and coded:

	�private String middleName;

	�� �

	� � @Named("tussen")

	� � @javax.jdo.annotations.Column(allowsNull = "true")

	� � @MemberOrder(sequence = "2")

	� � @Optional

	�

	But in the user interface it is still mandatory.�

	�

	Can somebody help?

	�

	Tnx, johan.

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.
