[Remote API] Unable to move a page from space to space.

When I try to change the space attribute of a page and save it, I get the following Remote Exception.

com.atlassian.confluence.rpc.RemoteException: You can't change an existing page's space.

I am able to perform the task as expected locally. Is there a different method I should be calling?

I posted a questions on the Remote API page and it was suggested that I open this ticket.
