hi,

i'm using Netbeans 6.0 for develop a enterprise application, when I do a find a element I have the posibility to traverse a relationship, but this the error in the application server:

Local Exception Stack:
Exception [TOPLINK-7242] (Oracle TopLink Essentials - 2.0 (Build b58g-fcs (09/07/2007))): oracle.toplink.essentials.exceptions.ValidationExc eption
Exception Description: An attempt was made to traverse a relationship using indirection that had a null Session. This often occurs when an entity with an uninstantiated LAZY relationship is serialized and that lazy relationship is traversed after serialization. To avoid this issue, instantiate the LAZY relationship prior to serialization.
