I try to use a NamePicker with a namePickerAggregator data provider. The NamePicker offers all NABs that are configured through the DirectoryAssistence but when choosing any NAB other then the primary address book, no content is shown. On the server console an error is shown:
HTTP JVM: com.ibm.xsp.FacesExceptionEx: Unable to open database: fdd_pnw.nsf
The included address books are not located in the root data directory but in a separate directory. From the error is seems apparent that the engine tries to open the chosen NAB with the correct file name but does not use file path. Indeed, temporarily moving the directories to the root solves the problem.
