Hello, I started with Adf faces, and get the same exception... Before the exception, there is : 18:59:38,421 ERROR [STDERR] 21 janv. 2007 18:59:38 oracle.adfinternal.view.faces.agent.AgentImpl <init> | ATTENTION: The agent type is unknown; creating an agent with null agent attributes. I searched a lot, but found nothing about this "agent type".... (and is there some available sources of Adf ? I think I'll look at the Trinidad adaptation to find what it want...). but before this : did you solve it ? and how ? many thanks.
