Never seen it before but my guess is that since you're not referring to an actual property of your class NHibernate cannot automatically deduce the type. If that's the case, you need to add a type attribute. /Oskar 2009/11/19 code_blocker <[email protected]>: > OK so I have the mapping file below now and I get the exception below > that:-) What am I doing wrong? > > > <?xml version="1.0"?> > <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" > namespace="HelloWorldNHibernate" > assembly="HelloWorldNHibernate"> > > <!-- Mappings for class 'Customer' --> > <class name="HelloWorldNHibernate.Customer" > table="Customers" > lazy="false" > dynamic-insert="true"> > > <id> > <column name="CustID" /> > <generator class="identity" /> > </id> > > <property name="FirstName" /> > <property name="LastName" /> > > </class> > > </hibernate-mapping> > > > > > > > System.TypeInitializationException was unhandled > Message="The type initializer for > 'HelloWorldNHibernate.NHibernateManager' threw an exception." > Source="HelloWorldNHibernate" > TypeName="HelloWorldNHibernate.NHibernateManager" > StackTrace: > at HelloWorldNHibernate.NHibernateManager..ctor() > at HelloWorldNHibernate.Program.Main() in C:\Documents and > Settings\yonatan\My Documents\Visual Studio 2008\Projects > \HelloWorldNHibernate\HelloWorldNHibernate\Program.cs:line 21 > at System.AppDomain._nExecuteAssembly(Assembly assembly, String > [] args) > at System.AppDomain.ExecuteAssembly(String assemblyFile, > Evidence assemblySecurity, String[] args) > at > Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() > at System.Threading.ThreadHelper.ThreadStart_Context(Object > state) > at System.Threading.ExecutionContext.Run(ExecutionContext > executionContext, ContextCallback callback, Object state) > at System.Threading.ThreadHelper.ThreadStart() > InnerException: NHibernate.MappingException > Message="Could not compile the mapping document: > HelloWorldNNHibernate.Models.Customer.hbm.xml" > Source="NHibernate" > StackTrace: > at NHibernate.Cfg.Configuration.LogAndThrow > (MappingException me) > at NHibernate.Cfg.Configuration.AddValidatedDocument > (XmlDocument doc, String name) > at NHibernate.Cfg.Configuration.AddXmlReader(XmlTextReader > hbmReader, String name) > at NHibernate.Cfg.Configuration.AddInputStream(Stream > xmlInputStream, String name) > at NHibernate.Cfg.Configuration.AddResource(String path, > Assembly assembly) > at NHibernate.Cfg.Configuration.AddResources(Assembly > assembly, IList resources, Boolean skipOrdering) > at NHibernate.Cfg.Configuration.AddAssembly(Assembly > assembly, Boolean skipOrdering) > at NHibernate.Cfg.Configuration.AddAssembly(Assembly > assembly) > at NHibernate.Cfg.Configuration.AddAssembly(String > assemblyName) > at HelloWorldNHibernate.NHibernateManager..cctor() in C: > \Documents and Settings\yonatan\My Documents\Visual Studio > 2008\Projects\HelloWorldNHibernate\HelloWorldNHibernate\Utils > \NHibernateManager.cs:line 22 > InnerException: NHibernate.MappingException > Message="must specify an identifier type: Customer" > Source="NHibernate" > StackTrace: > at NHibernate.Cfg.HbmBinder.BindRootClass(XmlNode > node, RootClass model, Mappings mappings) > at NHibernate.Cfg.HbmBinder.BindRoot(XmlDocument doc, > Mappings mappings) > at NHibernate.Cfg.Configuration.AddValidatedDocument > (XmlDocument doc, String name) > InnerException: > > > > > > > > > > On Nov 19, 11:01 am, Diego Mijelshon <[email protected]> wrote: >> You *have* to map the Id, but you are not required to have a property for >> it. >> >> <class >> name="HelloWorldNHibernate.Customer" table="Customers" lazy="false" >> dynamic-insert="true"> >> *<id column="id_col_name" type="id_col_type">* >> * <generator class="identity"/>* >> * </id>* >> <property name="FirstName" /> >> <property name="LastName" /> >> </class> >> >> Diego >> >> >> >> On Thu, Nov 19, 2009 at 05:53, code_blocker <[email protected]> wrote: >> > hi, >> >> > Say I have an object relational mapping.
