Hello everyone,
I have a Blog class, that has a <list> of Post in it. I can't manage
to update only the order, like this :
Post temp = myBlog.Posts[idx];
myBlog.Posts.Remove(temp);
myBlog.Posts.Insert(idx + 1, temp);
mySession.Save( myBlog );
When I do this, no update is issued, and the new order is not
persisted.
Am I doing something wrong ? Or shouldn't I use an indexed list for
this purpose (defining an order). I also tried swapping the two
elements (without removal), with no success.
Thanks.
PS. The mapping is like this :
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Blog"
namespace="Blog.Entities">
<class name="Blog" table="BLOG" >
<id name="Id" type="System.Int64" column="ID_BLOG">
<generator class="increment"/>
</id>
<list name="Posts" cascade="all" table="POSTS" inverse="true" >
<key column="ID_BLOG" />
<index type="System.Int32" column="ORDER" />
<one-to-many class="Post"/>
</list>
</class>
<class name="Post" table="POST" >
<id name="Id" type="System.Int64" column="ID_POST">
<generator class="increment"/>
</id>
<many-to-one name="Blog" column="ID_BLOG" class="Blog" not-
null="true" />
</class>
</hibernate-mapping>
