Error when editing dashlet tabs after deploying dashlet to user

[jamie]

Description of the problem

After deploying a new dashlet to a user using the append option, the dashlet tabs cannot be edited in any way.
It is not possible to:

• Rename the dashlet tab
• Reorder the dashlet tabs
• Delete the dashlet tab

The UI appears to block any changes to the dashlet tabs.

There are no errors in the EspoCRM logs and no PHP errors.
This appears to be a front-end validation issue rather than a backend or database problem.

---

Steps to reproduce

1. Deploy a new dashlet to a user using the append option.
2. Open the dashboard containing the appended dashlet.
3. Attempt to modify the dashlet tabs (rename, reorder, or delete).

---

Expected result

Dashlet tabs should be editable after deployment.
Users should be able to rename, reorder, or delete them.

---

Actual result

The dashlet tabs cannot be modified in any way.
All edit operations appear to be blocked in the UI.

I have tried to reproduce the behavior you describe in versions v9.1, v9.2, and v9.3.
However, in each case, Users can to rename, reorder, or delete dashboard and dashlet tabs.

Hi jamie,

Could you please check if there are any errors in the browser console when you cannot change dashlets/dashboards?

I don't know if its related but i do get a few of these

/#:1 Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received

though not just when i get the error

honestly it looks like a validation error but nothing is displayed to screen or logs
