So I have a InfoPath form embedded into my site, working with all aspects correctly, even when you submit it pushes that as a row into a datalist in another page. My concern is that 4 existing fields in my datalist exist and receive data into InfoPath from my current data connection, but will not populate a multi-select list box. I have other multi-select fields working. Here are some images to try to show my struggle (Its as if InfoPath just doesn't know how to populate it from the data passed by SharePoint, but in SharePoint all of the data fields are kosher..)
My next step is to delete each field not working and reinsert it, then try again. But I just can't think of what else this might be. The form works as expected other than this.
