exception occured on this line of code , when i want to add a list of objects : scope.Add(relatedDocuments);

The supplied instance is not of type Telerik.OpenAccess.SPI.dataobjects.PersistenceCapable (System.Collections.Generic.List`1[[EandE.DocumentControl.BSL.Entities.DCRelatedDocument, EandE.DocumentControl.BSL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]). Are you trying to add a wrong object or is the assembly not enhanced?

how can i solve my problem???

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,
