Russell Keith-Magee 9595183d03 Fixed #13724: Corrected routing of write queries involving managers. ... Previously, if a database request spanned a related object manager, the first manager encountered would cause a request to the router, and this would bind all subsequent queries to the same database returned by the router. Unfortunately, the first router query would be performed using a read request to the router, resulting in bad routing information being used if the subsequent query was actually a write. This change defers the call to the router until the final query is acutally made. It includes a small *BACKWARDS INCOMPATIBILITY* on an edge case - see the release notes for details. Thanks to Paul Collins (@paulcollinsiii) for the excellent debugging work and patch.		2013-09-30 13:05:43 +08:00
