Subject Re: Run query NOT in transaction
Date Tue, 27 Oct 2009 16:15:47 GMT
The problem that as usual I need to turn it off only in some "special cases".
Usual I am using InternalTransaction API.
Using of ProcedureQueries is not a solution in my case, we prefer
common RowQuery. :)
It' a solution to replace InternalTransaction by ExternalTransaction
(which actually do nothing) in such "special cases", so it' helps.
I just got this solution in mind. But it's not so intuitive... and
really ugly...

I will add issue on 3.1 Transaction mechanism is not a best part of
Cayenne .... :(
