NHibernate Integration - Object reference not set to an instance of an object

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Map a Parent & Child object. Parent -< Children, so Parent & Child are 
indexed.
2. Save Parent using NHibernate using cascade='all' or save children 
individually then save parent with cascade='none'
3. Getting various object reference errors either at DoWithEntities or Add and 
I think Delete.

Attached is a test output.

Sorry, you will need a field in the schema called Value, or alter the Mappings 
method to use an existing field.

Many Thanks :-)

Yeah in this case of Parent-<Children we would want to flatten into the parent 
object.  However it was our intention to store >1 entity type in the same index 
initially also storing entity type name in the index to allow searching only 
specific types.  I think this is how NHIbernate.Search works, not sure?  Have 
you ever done this, our application needs to search across many types at the 
same time ?

In Solr you should almost always flatten your object graph. Different unrelated 
types means separate cores. Please use the google group for further questions.
