FAQ

Which Odoo versions / editions are supported?

This module targets Odoo 19 and works with both Community and Enterprise editions, including Odoo.sh and on-premise deployments.

Do I need Odoo Enterprise Gantt?

No. NexGen Gantt is a standalone interactive Gantt suite built on standard Odoo Web. It does not require Enterprise Gantt.

Who publishes and supports this app?

NexGen Solutions publishes the suite. Support email: nexgensolutionsodoo@gmail.com.

Does Gantt invent workflow states like Confirm / Done / Approve?

No. NexGen Gantt is safety-first: adapters write schedule/planning fields only. Native Odoo forms and buttons remain the source of truth for workflow.

Are writes protected by ACLs and record rules?

Yes. Timeline reads and writes use the current user’s access rights. There is no sudo bypass for business data.

What happens if two users edit at the same time?

Optimistic concurrency checks apply. With NexGen Gantt Collaboration installed, presence chips and edit locks further reduce collisions.

Which time scales are available?

Hour, Day, Week, Month, Quarter and Year, with zoom in/out, reset zoom and zoom-to-fit.

Can I save my preferred Gantt layout?

Yes. Saved layouts store scale and polish options per user so you can reload your preferred view quickly.

What export formats are available?

Common formats include PDF, PNG, XLSX and JSON. Depending on the installed suite exchange gateway, XML/XER and optional admin-gated iCal may also be available.

Is the UI mobile / tablet friendly?

The shared chrome is responsive. For the best phone/tablet experience install NexGen Gantt Mobile (compact toolbar, touch drag, optional PWA).

Can AI help me reschedule?

Install NexGen Gantt AI Planner. It supports natural-language intents with preview-first apply through adapter validators.

How do I get the full suite at once?

Install NexGen Gantt All-in-One. It pulls Base, all business adapters, Collaboration, AI Planner and Mobile.

Is multi-company supported?

Yes, within normal Odoo multi-company rules. Users only see and edit records allowed by their company and record rules.

Will uninstalling remove my Odoo business data?

Uninstalling a Gantt module removes the module’s menus/actions/helpers. Native Project/MRP/Sales/etc. business records remain.

Where can I ask for customization or support?

Email nexgensolutionsodoo@gmail.com with your Odoo version, module technical name and a short description of the need.

What does NexGen Gantt Collaboration do?

It adds live presence, edit locks and bus-powered sync so multiple planners can work on the same Gantt safely.

Are locks only visual?

No. Peers see lock cues, and the server rejects schedule writes from another session while a lock is held.

What if someone leaves mid-edit?

Presence and locks expire automatically; a cron cleans stale rows so others can continue.

Does Collaboration change stages or MO states?

No. It only coordinates presence and schedule edit locks.

Which apps are required?

NexGen Gantt Base, Bus and Mail (Discuss).

Where do I see who is online?

A presence strip shows who is viewing the same adapter/session scope.

When is a lock acquired?

Typically while dragging/resizing a bar; it releases when the edit ends or the session leaves.

What does a locked bar look like?

Peers see a visual lock cue and tooltip naming the locking user.

Does this replace Odoo record rules?

No. Collaboration is additive; ACLs and record rules remain authoritative.

Is Discuss/chatter integrated?

You can jump to chatter/discussion for the selected record when needed.

How often is cleanup run?

A scheduled action cleans expired presence/lock rows.

Does it work across all adapters?

Yes — Collaboration is a companion for installed NexGen Gantt adapters.

Can AI apply while a lock exists?

AI applies respect locks and concurrency checks.

What is a session-stamped RPC?

Writes carry session context so the server knows which client holds the lock.

Do I need websockets/bus working?

Yes — Bus is required for live presence and lock broadcasts.
