[Bug] Undo stack grid disappearance when creating nested grids (Grid B inside Grid A)

[lunalar]

Bug Description

• Operating System: Windows
• Bug encountered on : AppFlowy application, on Windows (latest available update as of today)
• Version: Free plan with Cloud hosting
• Personal Severity: High (3/5)

Description of the issue:

When a new database (Grid B) is created inside a page of another database (Grid A) using the /grid command, two bugs occur:

• Bug 1 (Minor): Using CTRL + Z to undo an action inside Grid B (in grid view) causes the entire grid to reset to zero, resulting in the loss of existing content.
• Bug 2 (Critical): Closing the parent page (Grid A) containing the nested grid (Grid B) results in the permanent deletion of Grid B. The grid disappears, the page becomes empty, and it is impossible to restore the data via the trash/recycle bin.

Consequence : It is currently impossible to retain data within a sub-grid integrated into a main grid page.

How to Reproduce

1. Create a main database (Grid A).
2. Create a new page within this database.
3. Open the page, type /grid, and select "Grid - Online" to integrate a new database (Grid B).
4. Add some data into Grid B.
5. Close the page containing Grid B.
6. Reopen the page.

Grid B disappeared from the page containing it. The page is empty, and Grid B's data is unrecoverable.

Expected Behavior

Integrating a grid into a grid page must allow data retention and grid restoration upon reopening the parent page.

Hi @lunalar , I'm unable to reproduce this issue. Please upload a video recording to help us locate the bug. Thanks in advance.

Hello! Thank you so much for your quick reply :)
Since I couldn't upload the video here ( error ) you can download it here

While trying to reproduce the bug, I realised that the two issues are actually linked: in fact, Grid B saves correctly in Grid A, there’s no problem there.

The problem actually stems from Grid B disappearing when you press CTRL Z. If you restore Grid B using CTRL + Shift + Z, it is at this point that it will not be saved in Grid A, and you will lose the data once the Grid A page is closed.

Steps to reproduce the bug:

1. Create Grid B in Grid A page
2. Insert some content into Grid B
3. Press CTRL Z in Grid B
4. Then restore Grid B using CTRL + SHIFT + Z
5. Re-insert some content
6. Close the Grid A page containing Grid B
7. Return to the Grid A page containing Grid B: Grid B has disappeared.

Hope I'm clear enough, thank you again for your help! :)
