Subject [jira] Commented: (OPENJPA-1569) @Strategy triggers an InvalidStateException for fields which are declared as Java interfaces
Date Sun, 14 Mar 2010 19:07:27 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1569?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12845120#action_12845120
] 

Fay Wang commented on OPENJPA-1569:
-----------------------------------

Jerry, you are right. the field of address, which is of type BaseAddress is treated as PC_UNTYPED,
which causes the exception to be thrown in the later stage.

@Persistent
@Strategy("SimpleHandler")
@Column(name="address_packed")
private BaseAddress address;
public BaseAddress getAddress() { return address; }
public void setAddress(BaseAddress address) { this.address = address; } 

The workaround is to do the following:

@Persistent
@Strategy("SimpleHandler")
@Column(name="address_packed")
private java.io.Serializable address;
public java.io.Serializable getAddress() { return address; }
public void setAddress(java.io.Serializable address) { this.address = address; } 

where your BaseAddress:

public interface BaseAddress extends java.io.Serializable {
	public String getStreet();
	public void setStreet(String street);
}

> The @Strategy annotation works fine for classes but does not work if the field is a Java
interface.  Consider:
> 	@Persistent
> 	@Strategy("SimpleHandler")
> 	@Column(name="address_packed")
> 	private BaseAddress address;
> 	public BaseAddress getAddress() { return address; }
> 	public void setAddress(BaseAddress address) { this.address = address; }
> This works perfectly if BaseAddress is defined as a class but results in an InvalidStateException
if it is an interface:
> <openjpa-2.0.0-beta2-rexported fatal user error> org.apache.openjpa.persistence.InvalidStateException:
Encountered unmanaged object in persistent field "com.example.SimpleEntity.address" during
flush.  However, this field does not allow cascade persist. Set the cascade attribute for
this field to CascadeType.PERSIST or CascadeType.ALL (JPA annotations) or "persist" or "all"
(JPA orm.xml), or enable cascade-persist globally, or manually persist the related field value
prior to flushing. You cannot flush unmanaged objects or graphs that have persistent associations
to unmanaged objects.
