Our state of the art Gantt chart


Post by foursite »

Hi there,

I am trying to understand why Gantt is disrespecting the dates I sent through the database? The dates are generated externally, not through using the Gantt itself, so possibly I might be missing a point but I could not spot it yet. I'd really appreciate if you could put me in the right direction.

As you can see from DevTools the Start and end date are different than the UI, the WBS of the Task is 1.1.3.1

The Gantt engine always schedules tasks on load. So if the data is not scheduled properly it will be adjusted.

Hard to tell anything concrete looking at the pictures, but here are few notes that could be helpful:

  1. Make sure that your backend returns proper project start date
  2. Task can be either automatically or manually scheduled (defined by this field https://bryntum.com/docs/gantt/#Gantt/model/TaskModel#field-manuallyScheduled)
  3. Task position can be forced by its constraint (fields: https://bryntum.com/docs/gantt/#Gantt/model/TaskModel#field-constraintType, https://bryntum.com/docs/gantt/#Gantt/model/TaskModel#field-constraintDate). The Gantt uses Start no earlier than by default for forward scheduled projects.
