[jira] Commented: (CAMEL-612) Exchange should end in error when no choice in a ChoiceType matches

["Claus Ibsen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/activemq/browse/CAMEL-612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43478#action_43478 ] 

Claus Ibsen commented on CAMEL-612:
-----------------------------------

Gert I do think that the choice() should *always* have an otherwise() so there always is a match.

{code}
from(DIRECT_ROUTER).choice()
  .when(xpath("/oc:order_confirmation/oc:order/oc:customer/@category = '140'"))
    .to(DIRECT_CUSTOMER1)
  .when(xpath("/oc:order_confirmation/oc:order/oc:customer/@category = '116'"))
    .to(DIRECT_CUSTOMER2);
  .otherwise().to(DIRECT_CUSTOMER3);
{code}

If the otherwise() is missing on the choice() then Camel should thrown an exception. Maybe checked during the route creation stuff.

> When you define a route with a choice() and no matching when() clause is found, the Exchange just ends successfully without doing anything.  In my mind, it should fail by default in this case (or we should at least have an easy way to get this behavior).
