Subject [jira] [Commented] (CAMEL-5612) Can not define error handler at begin of two route simultaneously
Date Fri, 14 Sep 2012 09:04:07 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-5612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13455679#comment-13455679
] 

Claus Ibsen commented on CAMEL-5612:
------------------------------------

Yes move the error handler on the route, then its a route scoped error handler.

See this page, about the scopes
http://camel.apache.org/error-handler.html
