Unchanged transient field received as null on server using RequestFactory - how to force to send?

Hi all...

So I have a situation where we have an entity persisted with JPA on the server:

public class MyEntity ... {
    private String field1;
    private String field2;
    private String myTransientField;

... and we have a proxy:

public class MyEntityProxy ... {
    public String getField1();
    public void setField1(String field1);
    public String getField2();
    public void setField2(String field2);
    public String getMyTransientField();
    public void setMyTransientField(String myTransientField);

When I first make a call to the server to persist the entity, it works fine.

However, if I load it to edit it, and don't change myTransientField, myTransientField arrives on the server as a null value.

I had *thought* I had this working in the past, but for some reason I see it breaking now.

Is this the way it's supposed to work? (since the field hasn't changed, or because it's transient, or both)

If so, how can I get around this restriction, and force that field to be dirty, even if it is unchanged?
