Hi Erik,

I suspect the issue is because the datatype is a primitive (int), for which
nullable/optional doesn't make sense.

Perhaps change it to Integer?

Thanks, that helped.

Also: if you want a property to be always hidden, I generally use
@Programmatic rather than @Property(hidden=Where.EVERYWHERE).  The
difference is that the property is excluded from the Isis metamodel.
(Though if you are using auditing or XmlSnapshot or similar, then you'll
want to stay with @Property).

Ok, I'll keep that in mind.

While starting our application I get the following error:

nl.pocos.dom.billing.specification.AbstractTelephonySpecification#cdrExportId:
incompatible Isis' default of required/optional properties vs JDO; add
@javax.jdo.annotations.Column(allowNulls="...")

The property is defined as follows:

@Property(hidden=Where.EVERYWHERE)
     @Column(name = "export_id", allowsNull = "true")
     public int getCdrExportId()
     {
         return cdrExportId;
     }

Another property, defined likewise, has no problems:

@Column(name = "verlengingstermijn", allowsNull = "true")
     public int getAutomaticProlongationPeriod()
     {
         return automaticProlongationPeriod;
     }

I tried adding Optionalitity with no effect:
@Property(hidden=Where.EVERYWHERE, optionality=Optionality.DEFAULT) and
Optionality.OPTIONAL

I must be missing something.
