I've replaced a part in BasicForm.cs that loads the custom user control with this:

case "usercontrol":
string controlName = formNode.SelectSingleNode("settings/controlname").InnerText;
try
{
string controlPath = ConfigurationSettings.AppSettings["CMSMetadataFolder"] + @"/_CustomFormControls/" + controlName;
usrControl = ((KentiFormUserControl) (this.Page.LoadControl(controlPath)));
}
catch //(Exception ex)
{
string controlPath = "~/cmsdesk/metadata/_CustomFormControls/" + controlName;
usrControl = ((KentiFormUserControl) (this.Page.LoadControl(controlPath)));
}
usrControl.ID = GetAttributeValue(formNode, "column");
usrControl.Value = GetDataRowValue(formNode);
usrControl.DataDR = dr;
Controls.Add(usrControl);
break;

I've extracted some variables, and solved a bug

@"/_CustomFormControls/"

was

@"\_CustomFormControls\"

and gave an exception. The catch fallback doesn't work with me because my CMSDesk runs in it's own IIS application.

One code-style related comment: could you make the commands a little shorter? extract more variables? that would make debugging somewhat easier...

Thanks!
