Subject [jira] Commented: (ROL-1726) NPE when deleting a subscription with a URL that contains mulitiple param in query string
Date Thu, 05 Jun 2008 19:22:58 GMT

    [ https://issues.apache.org/roller/browse/ROL-1726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14364#action_14364
] 

Nathan Beyer commented on ROL-1726:
-----------------------------------

I did some further debugging and it looks like the wrong URL is getting submitted by the JavaScript
