I added a Notes subpanel-create component into let's say Account create view. But it seems it does not wait for the callback of the file upload function. So if the filesize is big (=slow) enough, the redirect of the page (after saving the main record) or auto-closing the drawer or what does cancel the upload. It leads to a Note record with right filename, but downloading the file gives "File information could not be retrieved for this record" - the filesize is 0 in DB etc.
Did anybody already solve this?
