Problems with Grid Filter Editor and SUMs

Hello Isomorphic,

We have a few grids that are loaded from a DS using SUMs for several fields in the <selectClause> section of the operationBinding. The problem we are encountering is that the grid's filter editor will not allow us to apply any filters to the data (be it on a SUM field or not). It won't show any errors or anything, it just returns an empty grid.

We are using v9.1p_2014-06-11/PowerEdition with Firefox v34 and Internet Explorer 11.

Thanks in advance
