the only one essential method

Parameters

  common | the actual "worker"
  service | pointer to Data Provider Service
  location | location of objects in TES
  checkData | whether to check if the pointer is valid before returning it

Returns
  the data

try to be efficient:

1. load object only once:
2. try to get the selection
3. try to get the container
