Grid filtering using combo loaded from db

I have set up the grid to load from the dataprocessor, and configured the filter for #select_filter.

The filter combo is loaded from the dataprocessor.

What is happening is that when filtering on the id, the grid displays items with a select code of 2, 12, and 22 etc when it should only be displaying 2, or 12, or 22.

Have I missed doing something in the grid setup (which is done in javascript).

Thanks.

Anyone ?

Plase, try to use #select_filter_strict instead of #select_filter
