Recent update from SP to ESC changed read access on tickets in portal view

[JStockel]

Hello friends,

We recently moved over from SP to ESC. Before, we had so that our employees with different departments (retail etc). Can read each others' requests within the same department.
So Department A, has person 1, 2 and 3. They should all be able to view and write in the Additional comments field. They can view them perfectly fine. But they cannot write in the comment field in portal view. The problem is, only in portal view. In backend view (where these users are not even working, they can write.


As the image shows, now it does not. I've checked through our ACLs, and they look like this, with snc_internal role on the associated table: 

Nothing else, than portal has changed.
The Standard ticket configuration filter is the same as well. Simply with Opened_by, and opened_by.department filter. It's in the Service Portal - Standard Ticket application... But so are the Incident, sc_req_item and another custom table on. They're all displayed as normally in the ESC. Although, these are not shared cross the department currently.

This is also a request table from a custom application. 

Anyone, who could possibly have an idea, of what could be the issue?

I actually managed to solve it. Difference was, that there's multiple widgets in the ESC version compared to the SP version.
The Standard Ticket Conversation and Standard Ticket Tab widgets, had to be cloned and put in Global scope, instead of the scoped Service Portal - Standard Ticket application.

So, if you ever have to unlock tickets to multiple people, for instance in our case, within same department. You'll have to simply put the widgets in Global application. There were a few lines only where we had to change the widget reference to the wrong widget, but simply search for Widget in the scripts and you'll manage to fix it quite fast actually.
