Re: Result Map nested properties in .NET

[Gilles Bayon]

It's is not supported in the .NET version (not a bug), you must use a resuttMapping attribut.

I gess you read the Java Guide.

I am trying to use an embedded object in a result map, but I get the following error:  

IBatisNet.Common.Exceptions.ConfigurationException:

- The error occurred while loading SqlMap .

- Check the Email.EmailResult. ---> IBatisNet.Common.Exceptions.ConfigurationException: Could not configure ResultMap. ResultMap named "EmailResult" not found, failed.

 Cause: There is no Set property named 'Message.To' in class 'EmailMessage'

Does the .NET version of 1.2 DataMapper support what the docs say regarding this?

This is from the dev guide for iBatis....

The solution is to use a join and nested property mappings instead of a separate select statement. Here's an

example using the same situation as above (Products and Categories):

Developer Guide iBATIS SQL Maps 2

http://www.ibatis.com by Clinton Begin

<resultMap id="get-product-result" class="com.ibatis.example.Product">

<result property="id" column="PRD_ID"/>

<result property="description" column="PRD_DESCRIPTION"/>

<result property=" category.id" column="CAT_ID" />

<result property="category.description " column="CAT_DESCRIPTION" />

</resultMap>

This is my result map definition:

        <resultMaps>                                           

                <resultMap id="EmailResult" class="EmailMessage">

                        <result property="Id"     column="ID"/>

                        <result property="Message.To"     column="TO"/>

                </resultMap>

        </resultMaps>

This is my EmailMessage Object:

public class EmailMessage : BaseDomainEntity, IMessage {





        private System.Web.Mail .MailMessage _message = new                              System.Web.Mail .MailMessage MailMessage();

       

       

        public System.Web.Mail .MailMessage Message {

            get {  return _message; }

            set { _message = value; }   

        }

}
