Kathryn,
Thanks for sharing such a great write-up! Your clear instructions helped me setup an OBS in my Project filter portlet.
When I follow the same steps to setup my Idea filter portlet, the drop down is empty when I attempt to map the OBS from the filter portlet to the sub portlet.
With this being an Idea filter portlet, I searched but didn't find an "OBS Idea Filter Browse."
Do you know if OBS filter portlet functionality is only available on the Project object?
Thanks again for sharing such valuable information!
James
