Open Source Document Management System | OpenKM

I am using OpenKM 6.3 and have downloaded source code from svn. I want to add an option in File upload form for cancelling the upload. Is it possible to cancel the file upload? If yes can you please elaborate on this with some example. Because as I am seeing in source code and understanding it, you are passing and setting many events at the time of uploading. So if possible can you please explain with example like code or something?

Can't you simple hit the refresh button in the browser? This should cancel the upload.

This option is good. But what I needed is to give a button that will cancel the upload. For that I need some sample code.

The change should be done in FancyFileUpload and in some way destroy the post what has been done. Any patch on this direction will be wellcome.

I have tried many things like setting the widgetState to Empty State on click of Cancel button but it was not working. Then I tried to close ffUpload and remove all pending files from queue if any, not worked. Didn't get any solution for this. Can anyone please give some ideas to do so?

Take a look you're submiting a form. The idea will be destroy this form what you're submitting and reset some vars to continue with next form.

fileupload var is a FormPanel ( take a look into the class ) Seems FormPanel is marked as deprecated by GWT and replaced by FileUpload. Here I see two possibilities ( extends actual FormPanel or investigate if it's possible doing with FileUpload, I suggest some sample in both cases before trying to change openkm code).
