This tutorial explains the Nextedy GANTT licensing model and guides you through configuring user access so your team members can view and edit Gantt charts.
Nextedy GANTT offers the following license models:
License Type
Description
Duration
Evaluation
Full functionality for testing
30 days from installation
Subscription
Annual license with updates included
1 year (renewable)
Perpetual
One-time purchase (upgrade licenses available)
Permanent
New licenses are available as subscriptions only. Perpetual licenses are available for existing customers as upgrade licenses.
The license status is visible on the Nextedy GANTT > License administration page and in the Gantt widget footer. When the license is invalid or expired, a license panel appears at the top of the Gantt chart with a link to obtain a valid license.
Copy gantt_lic.json to [POLARION_INSTALL]/polarion/license/
Restart the Polarion server (or reload licenses from the admin page)
Navigate to Polarion Administration > Nextedy GANTT > License to verify the license status
After the 30-day evaluation period expires, the extension is automatically disabled. If you need more evaluation time, contact Nextedy to receive an extended evaluation license.
Nextedy GANTT uses a dedicated Polarion user group to control which users have edit access to the Gantt chart. Users not in this group see the Gantt in read-only (Reviewer) mode.
Navigate to Global Administration > User Management > Users
Locate the group named nextedy_gantt_users
Add all users who need edit access to this group
If the nextedy_gantt_users group does not exist, create it manually in the Polarion user management interface. The group name must be exactly nextedy_gantt_users.
When a user has only Reviewer access, the Gantt chart displays in read-only mode. The Edit button is hidden, and task bars cannot be dragged, resized, or modified.
The Gantt chart also enters read-only mode automatically when viewing a Polarion baseline snapshot, regardless of user group membership.
If you run Polarion in a multi-node (clustered) deployment, the same license file can be used on both nodes. Copy gantt_lic.json to the license directory on each server node.
