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.

I don't think you can optionally transition quite like that. A decision would be the best way to do it AFAICS.
