The opposite: the include file for DFP2 works with the DFP1 page and the DFP2 progress bar works with the DFP1 page; however, the DFP2 form does not work at all.
a. it does not write the file to the folder (although the folder is writable)
b. it does not write the file name to the db (although that is configured through DataAssist)
c. it does not write the default file name if image is not uploaded
d. the progress bar does not work in the DFP2 form (although it works in the DFP1 form)
I will post a support ticket later today or tomorrow (I have to finish this project to pay some bills).
