IMHO this could be better achieved by centralized error handling =
specific for flow - or inherited from parent flow. This feature is still =
missing and I assume that it could solve many error handling situations. =
I proposed this requirement on user-list as well as on forum and the =
idea was to involve similar error handling mechanism to one in Spring =
Web. The base difference would be only in mapping exception/error to =
certain view in flow instead of view id to be used by SpringWeb =
ViewResolver.

This solution is not complex yet, but could be easily designed to =
elegant and plugable solution of centralized flow error handling.=20
