I am struggling with how to have a type inherited from BLB process updates when using WCF and a local dataportal
The SL client invokes BeginUpdate with invokes the BLB type's DataPortal_Update.
Then what?
Invoking Child_Update certainly executes the appropriate dataportal_*** method of each child, each of which invokes a WCF service to process its update. But I do not see how to tie the completion of them all to a ending method for _Update.
Having the BLB's DataPortal_Update invoke a service passing a dto of the entire list bypasses all the is it new, is it dirty, is it deleted logic of Child_Update.
Would someone please tell me what I am missing in understanding this.
