Hello again.
I've got it that I was doing something wrong. I've found and
removed
several commandments violations, employed MultiECLockManager for
properly locking everything... but I am still getting these errors!
How could I track where is that violation hidden within over 5000
rows of code?
There are many, many ways in which things can be done wrong. I
don't know of any easy way to find the source. If you can isolate
and reproduce the problem in a minimum set of steps, that will
reduce the amount of code you have to look at.
These errors raise without any visible dependencies.
Users report that even when system says that it could not save
something (because of that strange error), actually data is saved
and
can be reviewed after logging out and in again.
Something else is happening in your code then. Perhaps this is
not from a save? Nothing should get written to the database if
this happens during a saveChanges. Maybe this is happening in
your app just after saveChanges()?
Hmmm ....... half-saving transactions is a common problem when you
don't use a transactional database and no "transaction rollback" is
available when ec fails during a save. What database engine are you
using?
Now who would use a squirrelly mock database like that?!!?
Someone who acquires a Ferrari and drives it in first gear because
they have never used a "stick-shift" car before! :-P
