We are using Exportable datasubset plug-in in one of our tempo reports for “Export to Excel” feature. We are facing issues in exporting couple of columns from the report. The tempo report actually has a grid that show filtered results on screen along with a provision to export results to excel. While the grid seamlessly renders 24 columns, export functionality fails to do the same, although both use same query entity.
Failing columns are text strings with no visible difference from those that are successfully getting exported.

Excerpt from the log while all 24 columns couldn’t be exported.
