dto

I'm working now on a multi-tier project which has layers as following :

DAL
BLL
GUI Layer

and Shared DTOs between BLL and GUI layers.

I'm facing a problem in mapping the Objects from DAO To DTO, No problem in the simple objects.

The problem is in the Objects who have child collections of another objects. ex:

Author                      Category
--Categories      --Authors

the execution goes in an infinite loop of mapping

and it get more complex when I want model Self-join tables ex:

Safe     Safe
--TransferSafe(Collection<Safe>)        --TransferSafe(Collection<Safe>)

the execution goes in an infinite loop of mapping

any suggestions about a good solution or a practical mapping pattern?
