We have on one page Filter portlet and one portlet linked on 2 attributes.
When we create it than it works but later whern user try this portlet filtering doesnt work.
When I delete in filterportlet link to attrib. and create it again than it works. But not so long.
When I change setting for portlet filter section and show those 2 attributes in filter for this portlet and filter for first time in this filter - than from this time works filter portlet filtering too.
