View source for OCLOperators OnUpdate

OnUpdate is called just before the object is saved to the database. You can do things needed on every save operation here.

'''Please note!''' You can't create new objects from within the OnUpdate action - that will leave the newly created object unsaved.

For example, in the method body for OnUpdate, set this OCL:
 if self.existing then -- This avoids touching the object if it has been deleted  
   self.ChangeTime:=DateTime.Now; 
   false 
 else  
   false 
 endif
