Interwiki URL as node/nid instead of wiki/title

Have enabled pathauto module for the wiki content type and the pattern is set as wiki/[title-raw] . Still, the URL of the node we link using [[]] tag points to the default drupal URL (node/nid ) instead of wiki/title.

This occurs when we link to an existing wiki page using [[]] tags and doesn't occur for pages that are not yet created.

Solution may be to use Wikitools module which appears to solve the issue.
