Errors not passed to ZSyncDelegate

[MrRooni]

I cleared out all the registered sync clients and the schema using Syncrospector. I then fired up the ZSyncDaemon and a fresh copy of the iPhone app. My computer showed up in the list, but when I attempted to sync I got the following (expected) error at the command line of the iPhone app:

NSLocalizedDescription = "[NOTE: this exception originated in the server.]\nfailed to register client because: client named 4A74A770-8144-48FD-8141-5F1CD56A04F6-28988-0001BCC14D1FF439 wants to sync unrecognized entity named: com.nothirst.MoneyWell.BucketBalance";
} 2010-04-07 10:09:00.229 MoneyWell[28988:207] -[ZSyncTouchHandler connection:receivedResponse:] received empty response, ignoring

The trouble is that the ZSyncDelegate method - (void)zSync:(ZSyncTouchHandler)handler errorOccurred:(NSError)error was never called so the UI just hung out waiting for a response that would never come.

I found another case of errors not being passed to the iPhone: During a sync attempt I had conflicts. In the sync conflict resolution window on my Mac I clicked "Sync Later". The daemon threw an error but the iPhone never saw it.
Here's the log from the ZSyncDaemon:
