Hi. I am very new to nHibernate so forgive me if this Question is Foolish. I am Trying to Create a One to many mapping I am getting a Run time error. INVALIDCASTEXCEPTON

The Basic ideas is an Account can have Many Transactions.....

1)Account File:-
Mapping Files:-


<id name="ACCOUNT_NUMBER" column="ACCOUNT_NUMBER" type="System.String">
<generator class="assigned"/>
</id>

......

<bag name="Transaction" table = "Trans_History">
<key column="TRANS_ID"/>
<one-to-many class="Prasanth.TRANS_HISTORYEntity, Prasanth"/> </bag>

Class File:-

[Serializable]
public class ACCOUNT_DETAILSEntity
{
private string _ACCOUNT_NUMBER;
private IList Transaction; // To store Transactions.
}



2nd) Transaction File:-

Mapping File:-

<id name="TRANS_ID" column="TRANS_ID" type="System.Double">
<generator class="assigned"/>
</id>

<many-to-one name="ACCOUNT_NUMBER" column="ACCOUNT_NUMBER" class="Prasanth.ACCOUNT_DETAILSEntity, Prasanth"/>

The Respictive Class File:

private string Trans_id;
private IDictionary Account_Number;


Now this Throws an Error. Can Anyone help me out with this..

Thanking You

Also in the above Question My Transaction List of Account is Empty. How do i see that That List Get All the Transactions or A selected Few Transactions in the List.


Thanks

why is your Account_Number member variable in class Prasanth.TRANS_HISTORYEntity declared as IDictionary. I think it should be Prasanth.ACCOUNT_DETAILSEntity because it is referring to the ONE side of the MANY-ONE relationship, so it should refer to some entity not IDictionary

Hey samujob,

Thankz That Worked.

Now i have 2 More Qurstions:
1) How do i see that the Transaction List Get all the Values of the respictive Account. ie: My Account Class has an IList of Transactions. How does that get Populted.

2)Not very Important. But when do we use a IDictionary??


Thankz......
