Unexpected filter behaviour in ListGrid

Hi,
I'm having an unexpected behaviour in a ListGrid filter with "allowFilterExpressions: true". The same error can be reproduced in SmartClient hands-on demo.

In order to reproduce it, you have to open the "Grids -> Filtering -> Expression filter" item and perform the following actions:
1. Clear all the filter expressions, and press the "Filter" icon. (Now all the countries should be shown)
2. Enter "bah" (without the quotes) into the Country filter, and press Enter. (Now only two rows are shown)
3. Enter "spain" (without the quotes) into the Country filter, and press Enter -> NO ROW IS SHOWN, but you should see one row for Spain.

Thanks for you attention
