Hi,

I am getting the following exception when one of my collections is being lazy loaded and I can't for the life of me see where the mapping error is in my XML:

Code:
Could not load type 'System.Int32, NHibernate, Version=1.0.2.0, Culture=neutral, PublicKeyToken=154fdcb44c4484fc', check that type and assembly names are correct


The mapping in the Parent object looks like this:

Code:
<bag name="Children" table="Child" inverse="true" lazy="true" cascade="all-delete-orphan">
  <cache usage="nonstrict-read-write"/>
  <key column="ParentID"/>
  <one-to-many class="MyDomain.Child, MyDomain"/>
</bag>


Would appreciate any pointers to help fix this one.

Thanks,

Jason

The error is most certainly not in this part of mappings. Look for type="System.Int32" and change it to type="Int32" or "System.Int32, mscorlib".

Hi Sergey,

I just did a search in my entire project and I do not specify System.Int32 anywhere...I only specify Int32 in all cases.

Any other ideas?

Cheers,

Jason

OK...finally tracked this one down. I had a property in on of my classes of type "System.Type" that was being loaded from the database. But, in the database I had only entered "System.Int32" instead of "System.Int32, mscorlib".

Nothing to do with mapping at all in the end!

Cheers,

Jason

Hi!
I am just curious... you wrote:

in the database I don't understand... what database do you use that allows you to choose the types of the columns using .NET types?...

Hi,

It is a generic mechanism to allow the users to enter a value whose type is controlled dynamically, e.g. System.Int32 or System.Decimal or System.Boolean, etc. The users response is converted into a string for storage in the database and then converted back to the correct type as required.

It does feel a little clunky so I would be open to better suggestions!

Cheers,

Jason
