Description:

Hello,
Sorry for my English, I'm from Czech republic and I'm not good in English.
When I have "Wiev data" on some table and I click on "Filter (accesskey +
F)" and only adding data (column) for sorting and click on OK,
program show "Validation error" with message "can't execute an empty
query".
When I add any text to upper box "SQL FILTER" and delete all from this box
before click on OK, everythink is ok.

I think that problem is with different "null" and "string.Empty".

Thank you for the correction
Jiří Zapletal
