Hi,
can anyone help me out, I implemented Infopath form with managed
code, fully trusted, digitally signed. I usually publish the latest form
to SharePoint from library, whatever changes done. But whenever i did
changes in the form its taking new version number
and the form overwriting all the columns existed in the form library
when published. Also i found that in the Form Options of Infopath i
could see that there is no option says
"Automatically upgrade existing forms", I wondered once i look at this

If i try to open the existing xml form which was saved with earlier
version of Infopath Form in SharePoint Library, not opening the form and
poping up a message by saying "Schema validation error".
Please help me out and how can get back the option: Form options -> versioning -> Automatically upgrade existing forms
Thanks in Advance
