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

Sorry, yes, it was an EntityProxy.

My ideas to solve it were:

1) Use a ValueProxy instead of an EntityProxy
2) Use a ValueProxy for the @Transient String value (dunno how a transient value, expressed as a ValueProxy within an EntityProxy, would be handled, or if it's allowed)
3) Pass the changing/unchanging value as a separate String argument in the RF call
4) Intuit it is unchanged BECAUSE it is null, since the client always sets it to something, but never to null

I think #3 is the easiest in this case.

Is there any possibility that, in future releases (we're one release behind current), an individual field in a proxy can be set to 'changed'?  That is, override the default returned by isChanged()?  I think that could be very useful, and I don't see it as causing any hiccups in the way things already work.

Assuming an EntityProxy here, if the field is left unchanged, then it's not sent to the server. On the server side, the entity is loaded by the Locator and then the diff is applied. So if the Locator gets a null field, it'll be left null.
You may have to use a ValueProxy here…
