InfoPath Dev

Strange thing happened. We have had an infopath form that is submitted to a forms library in sharepoint 2007. Up until recently the published columns in the info path form in included frist name last name and site, now only the first name appears. The last name and site have dissapeared from 752 forms. However when opening the form the info is there and get re populated into the library after you re resubmit it. HAs anyone seen this? IS there a way to repopulate?

well there is a way, i dont know whether that will suit you are not, because that will overwrite the date created, date modified, created by, modified by fields.

go to the document library and open the folder, just copy the forms to some other location and then delete the forms and restore them from other location, that should help you. before doing this i would suggest to take list template
