While browsing across the Resources table in the Resource Type tab the following error message is logged:
@ <Error> <oracle.adfinternal.view.faces.model.binding.CurrencyRowKeySet> @ <BEA-000000> <ADFv: Rowkey does not have any primary key attributes. Rowkey: oracle.jbo.Key[], table: model.ResTypeVOImpl@620289.>
This is harmless and does not hinder any functionality.
