Will Not Be Addressed
The development team has considered the issue or request and concluded it will not be addressed. The issue's Additional Information section may contain further explanation.
It works correctly in the current release.
The following workaround allows values in the field to appear without null values: 1. Edit the schema.ini file to specify the field types appropriately and reload the map document and data. 2. Change the original text file by editing the first row of the data to contain the type needed for that column. 3. Ensure all the values in the column have the same number of significant decimal digits such as the following example where 80, 82.55, and 85.2 must be 80.00, 82.55, and 85.20 respectively.
