[jboss-user] [JBoss Seam] - Veto Page Flow

[tom_goring]

Hi,

Is there a way to veto the transition in a page flow... e.g. in the case of some business rule failure ?

E.g.

the bean wizard.saveStuff adds a bunch of faces messages and returns to indicate a fail.  


  | ..
  | <page name="PageX" view-id="/pageX.xhtml">
  |  <redirect/> 
  |  <transition name="previous" to="PageY"/>
  |  <transition  name="next" to="PageX">
  |   <action expression="#{wizard.saveStuff}"/>
  |  </transition>
  | </page>
  | 

In spring webflow you can define that you transition only transition on certain return codes.

I can see you could do this with a decision states but I would have to code one for each view state.

Thanks in advance.
