I am using the latest version of the CoreLab ODAC componenet suite to connect to Oracle packages. I am inquiring to see if anyone has ever used the TOraStoredProcs MasterSource,MasterFields,DetailFields properties and had them work. Currently I create the master and return rows and then I create a detail set the MasterSource to the mastersource and the Masterfields are set to the foreign key of the table and the DetailFields are set to the same. Any help please would be greatly appreciated.
