Hi all,
I have a problem with the file upload in Sling. I have a form that
uploads a file and an according POST.jsp for handling the upload. The
log shows that POST.jsp is resolved correct, but when I try to upload
the file, I get the following exception:
javax.servlet.ServletException: null

Seems like somebody is calling getReader() before ParameterSupport code
is executed. But I was not able to figure out where this happens.
Any ideas?
