When I create the column model, I assign identical value to label, caption and  index. When I start typing values into filtering toolbar for a column that has a space in it like "Assigned To",  I get an error that a ")" is missing.  Stepping through the code I found that when compare is happening it tries to access the access the column name as a property thus causing the issue:

(String(rec.Assigned To).substr(0,1) == String("O")) 

I tried removing the space from caption which prevented the error from happening but the grid was blanked out completely.  I am not quite sure if I am doing something wrong of if this is a bug.

TIA,
