Hi,
I've got a browser-compatible IP form that has several views. when the form
loads in the browser for the first time, it loads fine. However, when a
postback occurs, it throws the following exception:

Unhandled exception when rendering form System.Xml.XmlException: Unexpected

The IP form has 5 dataconnections. I suspected the issue had to do with one
of the dataconnections and I was able to narrow it down to a particular
SharePoint-list-based dataconnection that returns over 800 items. However,
this is pretty much a dead end as the dataconnection is most definitely
required.

While the issue seems quite popular on several forums and internet groups,
there does not appear to be any definitive resolution or ways to resolve it.

Perhaps you may be able to help out here.

Best regards,

Raphael Iloh.
