Spring Web Flow 2.2.0.RC1 基于 JSF 2 support in M1 构建，主要特性：
- JSF 2 Spring Travel sample built with PrimeFaces components.
- A Facelets tag library for the popular Spring Security framework including an tag and several EL functions.
- A working Portlet 2.0 and JSF 1.2 sample that builds on Web Flow's own Portlet support (i.e. without any Portlet Bridge for JSF dependencies).
- Upgarde to dojo 1.5 and inclusion of dojox in the bundled custom build.
