Dan Haywood updated ISIS-915:
-----------------------------
Description:
The description below shows the current behaviour; the core tries to interpret
the "Street" reference as a persisted entity.
The workaround is to have explicitly implement ViewModel (rather than annotated
with @ViewModel) and to traverse the graph manually. Using XmlSnapshotService
could be one way to do this (or at least to provide inspiration on how to
accomplish this).
Note though that ISIS-916 is a prereq in order to implement such as workaround.
~~~
Having this ViewModel annotated classes
{code}
@org.apache.isis.applib.annotation.ViewModel
public class Address2 {
public Address2(String lkmsId) {
this.lkmsId = lkmsId;
}
public String title() {
return "Address lkmsId:" + lkmsId;
}
public String iconName() {
return "Location_icon";
}
// {{ LkmsId (property)
private String lkmsId;
@MemberOrder(sequence = "1")
public String getLkmsId() {
return lkmsId;
}
public void setLkmsId(final String lkmsId) {
this.lkmsId = lkmsId;
}
// }}
// {{ Street (property)
private Street2 street;
@MemberOrder(sequence = "3")
public Street2 getStreet() {
return street;
}
public void setStreet(final Street2 street) {
this.street = street;
}
// }}
// {{ Housenumber (property)
private String houseNumber;
@MemberOrder(sequence = "2")
public String getHouseNumber() {
return houseNumber;
}
public void setHouseNumber(final String housenumber) {
this.houseNumber = housenumber;
}
// }}
}
{code}
and
{code}
@ViewModel
public class Street2 {
public Street2(String lkmsId) {

@MemberOrder(sequence = "3")
public String getPlz() {
