I'm working on a fairly complex InfoPath form and ran into an issue this morning after I added a multiple-selection list box and tried to populate it using a filtered data connection. After I added this and published it to a SharePoint site, the form appears to send postbacks over and over until it hits the server limit, no matter how high that limit is. I removed the field from the view and the issue went away. This seems to happen on any multiple-selection list box, even if i create a new one, and happens with any data connection (including the Choices Data Connection), but I can't reproduce this issue in other forms on other lists. Also, this only happens when I try to edit an item, it does not happen when I create a new item.
Any advice of how I can get my form to behave correctly without starting from scratch?
If you need any more info, let me know and I can provide it.
