Hi,

We've now got the 2010.1.330 build of the grid, and there's a bug with clearing and re-applying boolean filters (I think it's present in the 2010.1.309 release as well):
Apply a boolean filter - works OK (grid is filtered, as expected)
Clear a boolean filter - works OK (grid is unfiltered, as expected)
Re-apply a boolean filter - "internal server error 500".

I've found the cause of this - the "true" and "false" values are removed from the filter radio buttons as part of the "Clear Filter" operation. To fix it, I've made this change in "clearClick" function in telerik.grid.filtering.js:

    
                        // Original code 
        
                        //$element.parent() 
        
                        //        .find('input, select') 
        
                        //        .val('') 
        
                        //        .removeAttr('checked') 
        
                        //        .removeClass('t-state-error'); 
        
                        // Fix: Don't remove the "true" and "false" values used on the radio buttons for boolean filters. 
        
                        $element.parent() 
        
                                .find('input, select') 
        
                                .removeAttr('checked') 
        
                                .removeClass('t-state-error') 
        
                                .not(':radio') 
        
                                .val('');
