I am using Vaadin framework 7.4.5 and wcslib-vaadin-widget-multifileupload (2.0.3) I noticed that most of times, when I try to upload files, the upload status window hangs, though upload gets completed. How can I fix this?
I found the issue. it has to with using jetty, with older version of this add on. I upgraded the add on to latest version and vaadin to compatible version and used tomcat and it worked fine, so far.
