Hi @Biepa, Do normal image uploads save okay?

Are you able to re-produce the issue on the demo site?

Seems like it was only temporary. The time i tried it, it did not work in multiple diagramm on different pages. Don't know why.
Working know again.
May be hard to find out why, so i'll close this issue.

In my tests sometimes the hotkeys don't work, when the diagram is opened.
If I edit without shortcuts, it saves fine. But if I try to delete someting with "del" nothing happens and when I save, the diagram is gone.

We can confirm the issue. These are the steps to reproduce the bug:

In Firefox, create a new drawing
Press the del key; nothing will happen
Press save, the drawing will be deleted from the page

This does not happen in Chrome. It doesn't matter whether you are on Windows or Linux, the problem is with Firefox + Bookstack + Draw.io.

We suspect it's a problem with the way Draw.io is integrated into Bookstack. The del key seems to trigger the deletion of the drawing on the page instead of the element selected in draw.io

In my case it was worse, nothing gets saved after editing for an hour

I noticed that if the session times out, then the diagram gets discarded with no possibilities of saving it.

Since this issue is relatively old, and since there has since been changes to improve use of drawings I'm going to close it off.
If the issue is found to persist on current versions of BookStack, please open a new issue.
