Field events for file upload

hi,

which field event and functions can be used, when handling with files? On the website with javascript, I want to differ between the upload of a new file and the delete of a file to change some other fields value.

I already tried "change" and "edit" but without success: this.getValue()) and getControl(...).getValue() of the control have always an empty list "[]".

thank you, Helmut
