file upload;

How to access file via selected table object.

Hey guys,
I'm new to bonita and today I tried the upload widget by using this example:

So I can upload in one task a pdf-file and download it again in the next task. That works.
But now I want to download the file in another way. My project looks pretty simple, I have 2 forms and one Page.

Multi file upload in I'm trying to upload using htmlwidget

I'm trying to upload multiple files using htmlwidget with ajax jquery but unfortunately it is going to the next page with showing the names of uploaded files instead of working on background.

Any help will be highly appreciated.
