When is attachdata_postsave hook called?

[XTF]

When is the attachdata_postsave hook in includes\class_dm_attachment.php called?
In 3.8 it was called when attaching a file, but in 4.0 it doesn't seem to be called at all.

[Lynne]

It looks like it is called when the post is saved. Why do you think it isn't being called? Perhaps your syntax is incorrect for your plugin?

[XTF]

Wouldn't it show an error in this case?

I use errorlog('xbt_attachdata_postsave'); as code and this text is never logged.

[Lynne]

Don't you mean error_log?

[XTF]

Yes, but even then nothing gets logged.

[XTF]

Somebody?

[Lynne]

Are you even sure post_save_each_filedata is getting called?

[XTF]

No.
