InfoPath Forms Server Limitations

There are a few things in the InfoPath web based forms that are less than wonderful. A few. One of them is that large forms or forms with lots of logic will time out and cannot be published as web forms. OK. So your people have the client. Well, if these forms are taken down to the desktop from SharePoint it can take a couple of minutes to download. Literally. So large forms and complex forms are basically out in 2007. It is said that this limitation is not present in SharePoint IPFS 2010.

The definition of large or lots of logic is grey but I've found that while I was able to publish 875 KB form to web when I added some logic and brought it up to 1.2 MB It could not be published as a web form. Likewise, I did some tests on the logic piece and had 100 controls with perhaps 5 rules per control and that couldn't be published either. Not hard and fast so you will have to do your own testing to determine if your forms will make the web grade or not. I guess the point is there is a limit to how large or complex an InfoPath form can be when uploading to SharePoint as a Web form and it is inherent and immutably part of InfoPath forms server 2007.
