Parameters:

parentId - the Id of the StaffInfoFolder whose children should be loaded

con - the Connection to use to perform the load. Can be null.

Loads the list of StaffInfo/StaffInfoFolder objects for the given course (identified by id) from the database using a connection obtained through this object's database context.

The list returned is ordered such that a parent will always appear before a child within the list, and within a child group (group of child with the same parent) objects will be ordered according to their position value.

The returned list will always contain the "Top" StaffInfoFolder object as the first element in the list. The "Top" element acts as an anchor for the StaffInfo area and is a StaffInfoFolder which is the root parent of all other defined staff info items.

Parameters:

courseId - the Id of the Course that the list of staff info objects should be loaded for

Throws:

KeyNotFoundException - if the given course id is invalid

PersistenceException - if some other error occurs while loading the object

loadByCourseId
