> It would be nice to have a null-value attribute for properties (or types). Setting null-value="default" would mean that the default value for the type (DateTime.MinValue, 0, false) would be taken as NULL. It's mostly useful for DateTime so that people who want to have null dates don't have to use the Nullables library.
> Other values should be allowed too, just need to think how to parse the attribute value for user-defined structs.

[nhibernate-issues] [JIRA] Created: (NH-791) Add always-wrap As a Configuration Option On Collections

From: NHibernate J. <mik...@us...> - 2006-11-05 13:27:32

Add always-wrap As a Configuration Option On Collections
--------------------------------------------------------

         Key: NH-791
         URL: http://jira.nhibernate.org/browse/NH-791
     Project: NHibernate
        Type: New Feature
  Components: Core  
    Versions: 1.2.0.Beta2, 1.2.0.Alpha1, 1.2.0.Beta1    
    Reporter: John Chapman
    Priority: Minor



In order to easily accommodate custom collections NHibernate should offer an option to always wrap the collection instance from the target object.  Basically when NHibernate creates a persistent collection from a transient collection it will take the existing collection and wrap it's own persistent collection type around that collection so that the user's collection still exists underneath and performs its own logic.  

Add a new configuration option to all collection types called always-wrap which has a type of true/false and defaults to false.  When a new persistent object is loaded from the database for this type if always-wrap is true it will take the already created collection and wrap it with a new persistent collection instead of instantiating its own collection type which implements the same interface.  

As long as the user collection implements the correct ISet/IDictionary/IList interface the the user would be done adding their custom collection.

[nhibernate-issues] [JIRA] Updated: (NH-779) abstract class not recognized using multiple mapping files

From: NHibernate J. <mik...@us...> - 2006-11-03 10:07:25

      Component: Core
    Description: 
When an abstract class and (one or more) joined-subclasses are not in one mapping file, but joined-subclasses are in separate mappingfiles, the connection between the abstract class and the joined subclasses is lost. An error of 'cannot instantiate abstract class' occurs.

[nhibernate-issues] [JIRA] Commented: (NH-738) HQL select new generics support

From: NHibernate J. <mik...@us...> - 2006-11-02 21:29:31

---------------------------------

Thanks Fabio. I had come that workaround but was hoping the parser upgrade might not be so difficult.

> Given class Pair<int,string> that has a constructor Pair(int i, string s), HQL fails to parse out the generic parameter tokens when trying the following expression: 'select new Pair<int,string>(p.Id,p.Name) from Person p'
> The <import/> is used to pull in this custom Pair class.
> The default error " , expected in SELECT ..." appears, but this is misleading. 
> Actually, the tokens in the QueryTranslator class' ConcreteQueries() method aren't parsed correctly when generic "<>" symbols are present in the query. It reads the comma in the generic parameter list as a field separator and doesn't recognize the less-than/greater-than symbols. 
> Seems like this could be a powerful and (simple?) improvement ...

[nhibernate-issues] [JIRA] Commented: (NH-784) NHibernate should throw exception on failed driver load

From: NHibernate J. <mik...@us...> - 2006-11-02 14:35:40

Fabio Maulo commented on NH-784:
--------------------------------

Yes, but is different than H3.2 work.

Any way... i think that:
- Exception if an unknown property was found in session-factory section. 
and/or
- Change the nhibernate-configuration.xsd

is a good improvement to prevent some others issue.

> For full background on where this issue arises from, see http://forum.hibernate.org/viewtopic.php?t=966582&highlight=
> When Configuration.Configure() is called, if NHibernate is unable to load a database driver for whatever reason (missing dll, incorrect hibernate.cfg.xml, etc) it falls back to returning a UserSuppliedConnectionProvider without an ADO.Net connection attached to it. This causes any use of Session (eg accessing database) to throw an exception. This is extremely difficult to debug, as there is absolutely no indication as to why a UserSuppliedConnectionProvider is returned.
> I propose that instead of returning a UserSuppliedConnectionProvider, NHibernate should throw an exception along the lines of "Cannot Load Driver", and give a reason why.

[nhibernate-issues] [JIRA] Commented: (NH-789) ORA-08177 not wrapped as StaleObjectException with Oracle.DataAcess

--------------------------------------

Well, I can't do anything if the driver doesn't want to store them.
As for the exception you are getting, I believe it has nothing to do with NHibernate. Feel free to prove me wrong.
