We are using FNC Gantt Chart 1.3.3.1. While the PDF export demo is working, PDF export is not working for other project task structures, especially those with one root (top-level) task without a WBS number and all other tasks being sub-tasks of the root task with WBS numbers. We found that the functions TTMSFNCGanttProject.GetTaskByCount and TTMSFNCGanttProject.GetNextTask are causing the issue which rely on every top-level project task to have a WBS no. Thus, on PDF export, they only return the root task and then return nil.
Could you please explain how you you make a task without WBS number?
Ok. We have extended the FNC Gantt Chart to set a custom WBS number, since the model data already provides the WBS number.
