I'm using the file upload async with a single file, auto upload is off.
I'm using the file uploader in a multi-step procedure. When a file is uploaded, it's in a pending state, and it can be removed by the user with the X. However, if the user clicks the clear button, it's cleared from the list, without processing removal, and the file is orphaned. Is there a way to disable the clear button once a file is uploaded?
