Hard crash when saving

[robinp]

I am trying to edit a series of PDFs to redact sensitive information.

Upon completing the edit of one file, I tried to save and not only did Designer crash, it crashed and restarted my whole machine without warning.

Connected to this, I am editing PDFs and then trying to save them back as PDF. It is REALLY annoying that it is not possible to edit and save the PDFs without Designer wanting to save as a AFDesigner file. All I am doing is opening, deleting and wanting to save. 

Instead, I have to open, edit, not save as work progresses and then export to overwrite the original file.

It was this clunky workflow that resulted in the aforementioned crash. I was editing the file, hit save and then remembered I needed to export, so I hit the escape key. Designer paused for a few seconds and then completely crashed my MacBook Pro.

Not sure if it is connected or not, but there is another, softer crash that occurs when when opening PDFs by dragging them onto the designer window.

For example:

1. Open a PDF via dragging it onto the designer icon, or via the open dialogue.
2. Edit the file
3. Export to save the file back to PDF
4. Close file (but not designer)
5. Drag a new PDF onto the designer window that is still visible despite there not being a file open

At this point nothing happens.

If you then try to open a file by, for example, dropping it on the designer app icon, it opens but then you cannot do anything.

My hunch is that the dialogue that appears when opening a PDF doesn't properly generate when opening via dragging a file onto the designer window. It is like it is waiting for an interaction but without any pop up window visible.

The only solution I've found is to force quit and start again.

Hi @robinp,

When you open/import a PDF, you cannot "Save" back to it, as we don't exacly open it, but actually interpret the PDF and "convert" it. Therefore, you would need to Export rather than save. This is not a bug, but by design. 

As for the crash, I could not replicate it. Can you attach a screen recording of your workflow?

Hi @Gabe

Thanks for getting back to me but it was three weeks ago and I'm afraid I now cannot recall which files were causing the problems. I'll have a go again and see if I can recreate it but when I was doing it, it kept happening over and over again.

With regards to the opening vs converting, my point was that it would be much easier to give the user the option of using it as though it had been opened rather than converted. I don't think end users really worry about such subtleties, we just want it to work quickly and easily with the interface getting in the way as little as possible.

So whether the file is actually being opened or actually converted, I think it would be helpful to offer the option to open and save PDFs without going through this palaver.

While the current implementation may be by design, I struggle to see how it is of benefit to the user. It may make sense to a programmer writing the code behind it, but for the average user this differentiation is somewhat forced and just makes the workflow clunky.
