Drill down portlet is failing until params are passed

I have a set of two portlets, a pie chart that drills down into a list. These portlets both reside on a tab in a portlet page with tabs. When I go to the tab for the first time in a session, the list portlet shows an error (blank error, no messaging).

I believe this is because the query that the portlet is based on is expecting the four link parameters, but those parameters are blank, since I have not clicked on anything yet.

Is there a way, either in the query or in the portlet, to have the list portlet just show up as blank if the parameters are not set? That is the desired behavior.
