These are non critical errors.. The assertion is in the stats module and there is a bug I haven't had time to nail down yet.. The FormBeanConfig error is also something I haven't found a solution for.. It came up with the latest struts version.. Any help is welcome.. Ludovic hiranthab@srilogic.com wrote:
