1)outcome matching an exact from-view-id
2)outcome matching a wild card from-view-id
3)use the rule which does not specify a specific from-view-id

Add a

<redirect />

after the

<to -view-id></to>

<navigation -case>
   <from -outcome>ok</from>
   <to -view-id>/welcome.jsp</to>
   <redirect />
</navigation>
