OperationListener behavior in new projects

Hi,

It seems that an OperationListener can be attached to DataLoaderPool and 
it even fires events like operationMove, operationDelete, etc.  
Unfortunatelly, i.e. after deletion of some DataObject, it is not 
possible to find out to which project this DO belonged. Because, if you 
look for the project via Project.findAll(DataObject), (DataObject can be 
retrieved from OperationEvent) no project is found.

Is there any replacement for OperationListener in new projects or is it 
still valid for using?

Thanks,
Mato
