Hello amir sherafatian,

You should initialize the collection fields inside the FCDocument class:

private IList<DCRelatedDocument>
FRelatedDocuments =
new List<DCRelatedDocument>();

In order to achieve this goal you should do the following:
1.  Remove the Transient attribute for the FRelatedDocuments;
2. Check from Forward Mapping | Persistent | Object | Relation  | Manage Collection option;
3. Now you can simply add child in Parent Object;
Hope that helps.


All the best,
