Reply To: 'DBNull' to type 'Integer' ERROR


Hi Agnes,

The most likely cause for this error is a bug in Version 3.1 related to the new spatial functionality. To work around this bug go to the Run Control tab of the scenario properties. Select the ‘Run Model Spatially’ checkbox and save your project. Then uncheck this box and save your project again. This bug was fixed in version 4 of Path. Let me know if this does not resolve your problem.
