Nope, Seam cant do much about exceptions which occur at this point. As I've said here many times, JSF exception handling sucks ass, your only option is to beg for proprietary features from the JSF implementations. If you read the JSF spec, it actually says explicitly that JSF implementations should swallow and ignore exceptions that occur in phase listeners.
