adding a new file handler , without a specific path , fails with no indication of error.

Also since the dialog does contain a generic path for log files, not specifying a new one should work

here is the trace from log file

11:28:25,030 DEBUG [org.jboss.as.controller.management-operation] (HttpManagementService-threads - 21) JBAS014616: Operation ("add") failed - address: ([

]) - failure description: "JBAS014704: '' is an invalid value for parameter file. Values must have a minimum length of 1 characters"
