Hi,
Can you please let us know which version of Nintex Workflow you are using, we found an issue where recursive was causing the Where clause to be ignored. This has been fixed in the latest builds.
There are two ways to determine which version and build of Nintex Workflow 2007 you have installed.
The first is to navigate to any list or library in a site that has Nintex Workflow 2007 activated. Then load the Workflow Designer by choosing to create a new workflow or by editing an existing workflow. Open the configuration dialog for any workflow action and a build number will appear at the bottom left in grey text. The number is comprised of 5 digits in the format “1XXXX”.
The other way to determine your version number is from within SharePoint Central Administration. In Central Admin, click the “Application Management” tab, then scroll to the Nintex Workflow section and click the Licensing link. The build number should be visible at the bottom of the licensing information that is displayed.
