Bug 200919 Add quotation for column containing separator character when export data.[0002]
Description: Add quotation for column containing separator character when export data. Build number:2.2.1.v20070823 Steps to reproduce: 1. New sample data source and dataset. 2. Add a computed column with name a,b and value "a,b". 3. Drag the dataset to Layout. 4. Preview in Web Viewer and Export Data with Comma. Expected result: Column name is quoated as values. Actual result: Column name a,b isn't quotated so it will be treated as two columns. Error log:n/a
