Hi, I put an input file field in the form of my task. The file is successfully downloaded. But when I try to get the file in the next task, i have the exception :

This one is the BEST answer!

I suggest you to use a document, this way you can control the versions and make search using the API. Select a pool (or a lane) and choose the General tab. In this tab, go to the last option "documents" and create a new one.

To change the file load go to your load form and change the output operation of the file widget to this new document. Then click at "Takes value of" and select "Set document".

To change the file download go to your download form and simply change the initial value of the file widget to the document variable.

I just test it and it works perfectly ;).

java.lang.ClassCastException: org.bonitasoft.engine.bpm.document.DocumentValue cannot be cast to java.lang.String - See more at: http://community.bonitasoft.com/answers/how-put-download-document-field-previously-uploaded-version-625

I think that you have the document variable in a text field and the casting is not possible. Otherwise you are storing the document in a text variable.

First, thanks for the answer. My document variable is in an Object Java (org.bonitasoft.engine.bpm.document.DocumentValue) And I'm trying to store the document in a File field. Any idea ?
