- by Ninu
hello....i'm newbie developer....
i really need help at now...
i just get started with Nhibernate thing at .Net...
when i learn Inheritance and try it...it makes me confusing...why i get error like this :
Initializing[AP.Core.Domain.AccountPayable.APInvoice#API03/04/2010/001]-Could not initialize proxy - no Session.
this is my xml :
<class xmlns="urn:nhibernate-mapping-2.2" mutable="true" name="AP.Core.Domain.AccountPayable.APAdjustment, AP.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="APAdjustment">
<id name="AdjustmentNumber" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<column name="AdjustmentNumber" length="17" />
<generator class="assigned" />
</id>
<property name="Amount" type="System.Decimal, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<column name="Amount" />
</property>
<property name="TransactionDate" type="System.DateTime, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<column name="TransactionDate" />
</property>
<many-to-one class="AP.Core.Domain.AccountPayable.APInvoice, AP.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" lazy="proxy" name="PurchaseInvoice">
<column name="PurchaseInvoice_id" not-null="true" />
</many-to-one>
<joined-subclass name="AP.Core.Domain.AccountPayable.APCreditAdjustment, AP.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" lazy="true" table="APCreditAdjustment">
<key>
<column name="APAdjustment_id" />
</key>
</joined-subclass>
</class>
</hibernate-mapping>
and this is inheritance Class :
Parent Class --
public class APAdjustment
{
#region :FIELD
private string adjustmentNumber;
private decimal amount;
private DateTime transactionDate;
private APInvoice purchaseInvoice;
Child Class --
public class APCreditAdjustment : APAdjustment {
public APCreditAdjustment(){
and this my Data access :
public IList<APAdjustment> GetByNameAll()
{
ICriteria criteria = Nhibernatesession.CreateCriteria(typeof(APAdjustment));
return criteria.List<APAdjustment>() ;
}
My Problem is :
when i load data with gridview ...it
works...but i change the property to
autogenerate="true" ...i missing
"PurchaseInvoice" field...and i
change to bind manually,and it
works..when i edit that gridview
...i get this
error...
Initializing[AP.Core.Domain.AccountPayable.APInvoice#API03/04/2010/001]-Could
not initialize proxy - no Session
so then i change my xml
...lazy="no-proxy" ...it still
work...but when edit again ...i get
error again ..and i do "Comment out
the selected lines" to my
association "Many-to-one"...i really
works it..but that's not i want...
CAN ANYBODY HELP ME...??Plizz...:(
Note : I almost forget it ,i use fluent hibernate to generate to database.From fluent Hibernate ..i put *.xml file ...so i'm work to xml NHibernate...not fluent hibernate thing...:)
