Any Idea?


        ��private PersonGenderType gender;

        � ��@javax.jdo.annotations.Column(allowsNull = "false", length = 
JdoColumnLength.TYPE_ENUM)

        � � @MemberOrder(sequence = "50")

        � � @Named("Geslacht")

        � � @Hidden(where=Where.ALL_TABLES)

        � � public PersonGenderType getGender() {

        � � � � return gender;

        � � }

        �� �

        � � @Hidden(where=Where.OBJECT_FORMS) // appears only in tables

        � � @MemberOrder(sequence = "55")

        � � @Named("Geslacht")� �

        � � public PersonGenderType getGenderForTables() {

        � � � � return getGender();

        � � }

        �

        � � public void setGender(final PersonGenderType gender) {

        � � � � this.gender = gender;

        � � }



There's a couple of tricks you can do to order columns in a table
separately from as an object form.

One technique is to use member groups to group on the object form.  The
groups are then laid out in the order of @MemberGroupLayout.

Meanwhile, (I'm pretty sure that) the columns of the table are laid out per
@MemberOrder(sequence) without regard for the member group.  So with a bit
of playing around you can get the columns to appear in a different order.

The above technique has been all we've needed for Estatio.

~~~
Alternatively, (more boilerplate but perhaps more maintainable) you can
create derived properties and then hide the originals as required, eg:

public class Customer {

    @Hidden(where=ALL_TABLES) // appears only on object forms
    @MemberOrder(sequence="1")
    String getFirstName() { ... }

    @MemberOrder(sequence="2")
    String getLastName() { ... }

    @Hidden(where=OBJECT_FORMS) // appears only in tables
    @MemberOrder(sequence="3")
    @Named("First name")
    String getFirstNameInTables() { return getFirstName());

}

In an object form, you should see: firstName, lastName.
In a table, you should see: lastName, firstName
