Error in Log while MasterTicket created by Phone Call

[yuri0001]

Hi!
I create a new PhoneTicket with assigning the attribute "NewMasterTicket". The new ticket is created.
Then I create a request with an attribute "Slave" from the previous ticket. Also created. Outwardly, everything is fine.
But then, suddenly discover in the log:

Системный журнал_28_09_2011_Error.png

I.e., the bug had appeared immediately after the Master ticket created.
After creating the Slave ticket message no longer appears. It is not clear - this is a mistake, do not tip. But the Slave application may not appear immediately.
Or something I do not understand in the mechanism of Master-Slave feature:?
This possibility, in principle, necessary - for example, a proposal to replace the cartridge, followed by a subordinate to purchase or delivery from the warehouse.
Help, please to understand!

It seems it works, more or less, as designed. There is no point in making a Master designation without a slave attached, so it warns of that.

Good day!
Thank you for reply!
Yes, I see that works, but it is more correct for system it would give a warning instead of error
