I am trying to pass through the selection of the (idea) manager in a page filter on a portlet page to all portlets on said page. The filter is built upon the manager field on inv_investments and in the filter mappings page the Manager attribute shows up as Lookup - Number data type. No matter what I do, I cannot get any value populated in the Mapping field drop down for my grid portlet. Therefore I cannot establish the mapping. I rebuilt the grid portlet after making a number of changes to the underlying query. Still no field to select for mapping. My query and portlet both return the user_id of the manager as well as the full_name field. When I build a portlet based on the idea object (no custom query) the mapping works flawlessly. What I am doing wrong? Anything I need to do in the query to make the field show up in the dropdown for mapping? I've looked everywhere for a solution.
