When an XML Data Source is used and an empty XML result set is returned, any basic repeater attached to the XML Data Source will throw an exception.

We are using Kentico Version: 4.0 Build: 4.0.3328 and in this case no custom code.

For example, if the following result set is returned to an XML Data Source:

<?xml version="1.0" encoding="utf-8"?><SEARCHRESULTS></SEARCHRESULTS>

then any Basic Repeater attached will throw the following exception:

Server Error in '/' Application.
