SK>And here the sequence of creating objects:
SK>
SK>- first the user is loaded into the current transaction

SK>- Construtctor of FolderMapping:

SK>
SK> if(pParentFolderMapping != null)
SK> {
SK> pParentFolderMapping.addChildFolderMapping(this);
SK> }

SK>If pDatabase.create(this) is called, I get the StackOverflow Error.
