Hello developers,
i try to use the upload function. I use a form with a text Field, a
Textare and some checkoxs and an input Type of file. If write somthing in
these fields and choose a file to upload the behavior is good. The Upload
will be executed. When i write only somthing to the other input elements
(file choose is empty) I get an exception like this:
Processing of multipart/form-data request failed. Stream ended
unexpectedly
This happens only if no file is choosen. Only the values of the other
fields will be submitted. This Part of code throw the exception.
items = upload.parseRequest(request);
Perhaps i make somthing wrong ...
Perhaps it is a bug ....
I don't now ....
Best regards
Michael Laube
