Selecting columns in dashboard with different entity types should display the intersection

[EinatAR]

Based on the below bug, that has not been implemented yet, the request is to be able to select columns in comm among the different entity types selected.

Description

On creation of a "list" widget, when adding the filters entity type equal RFI and/or IR (together), the option to add the column "Assignee" isn't available.
(Same for: Priority, Severity, Response type, and Participant)

This behavior is the same for all of the cases. All columns option available for each case separately, but limited every time you want to include another case type (RFI, IR, Tasks)

Environment

OpenCTI version: 6.5.0

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Create a new widget with the representation "list"
2. Add the filter entity type equal RFI and/or IR (both)
3. Click "customize columns" and there's no option to add "assignee"

Expected Output

Have the option to add "Assignee"

Actual Output

No option to add "assignee" (also: Priority, Severity, Response type, and Participant)

Additional information

When creating the widget only for RFI alone or IR alone, "assignee" column is available to add.
It is only when the two (RFI and IR) are together in the same widget, that "assignee" isn't available to add.

Screenshots (optional)

Entity type = RFI or IR

Entity type = RFI

Hi @EinatAR, it's not a bug, it's a feature 👼 If you have only one entity selected we take the corresponding columns if there's is more some columns are not shared between entities (Ex: Report and Grouping are not the same).
On your case maybe we could make an intersection between IR and RFI columns (priority, severity, objectAssignee, objectParticipant), but it require product overview.
I'll let @nino-filigran confirm 🙏

My bad @EinatAR, I've removed the bug too quickly.
Indeed, for now, we did not introduce the intersection as part of the choice of columns. I'll turn this ticket as a feature, since it's definitively something we want to to do.
