You can implements your own batcher and inject it through NH configuration.
In your batcher you can nullify the row-count-check.
When you will have a real issue related to updated rows you can light a
candle in church and pray a while to find it.

How about giving us the full stack trace of this exception? We can guess all
day about the source.

There is a problem in your query "groupID" is the name of the Column, but
the name of the property seems to be GroupId.
But, this is not the cause of the object reference exception, by sure.

When Equals is overridden, calling it causes proxy initialization.
But if you are loading the currencies in the same session, you don't need to
do that; NHibernate will create only one instance of each Curreny, so
default Equals or even == comparison will work.

If you have a particular issue using one of the new Oracle dialects, please

Hi George
When I use the fetch function it allows me to pull back an entire
hierarchy in one sql call as it uses joins instead of separate sql
calls. I'm not sure why your hieracrhy is creating so much sql.

why not use a 'timestamp' type instead? A date/time field is never going to
work, as SQLServer stores it with a precision of 300ms, so every action on
the row within 300ms will look like it's ok, while it's not.

Okay, I figured out what the issue is, but still wondering what to
do. The table is defined with the SQL datatype of "smalldatetime",
and therefore doesn't store the actual SECONDS portion of the time,
but nHibernate passes that in and therefore can't find the timestamp
value.

Hi,
Here you go.
Equality is tested by the Equals function below, that is what calls
the Id property.

That's certainly some workaround. But not exactly I want. I don't want

Hi,
I have a problem with NHibernate loading too much data.
I have classes with an Id property, there are some many-to-one
relationships based on an the Id.
So for example a Country has a Currency.
I have a table of Countries and one of Currencies and there is a
CurrencyId column in the Country

Forgive me if that's posted somewhere, but even browsing the source I
didn't see a difference between what I have in
NHibernate.Dialect.OraclexxDialect and what was in the repository. I
do see your comments on checkin indicating that there were new
versions, but I wasn't sure where they may be.

For exactly this reason, you shouldn't really bind directly against
your domain entities; you should project those entities into DTOs and/
or ViewModel's and bind against those instead.

If your question isn't NHibernate related, it probably shouldn't be
asked on an NHibernate mailing list.
