Hi there - Is there a reason you used users, instead of the resource for the model in odoo?
This has caused some issues in our usage, in regards to the models in odoo:
some employees are users, but not all
all employees inherit from the resources model
This would allow greater flexibility too, since all resources are not necessarily human. You could schedule a expensive piece of machinery etc, which can also be a resource in odoo.
Resources also have a working time which basically maps to calendar in bryntum. Could this also be included instead of being hard coded into the config of the gantt?
Thanks
