I have an InfoPath 2007 form with a web service therein. that I have published the form to a SharePoint 2010 site and converted my web service data connection to UDCX in the Data Connection Library in the site. InfoPath Forms services also has cross domain settings applied correctly. Somehow I still get a cross domain erro when trying to call the web service in the form via web page. I am STILL getting the cross domain restrictions error in my form. Works fine in the thick client.
I've done this before a long time ago, so perhaps I'm doing something wrong since it's been a while.
