I have a XML file and a form. They are located in different libraries in SPS. XML file has some filled fields. I need form to retrieve data from XML file and put it into its own fields. So, I make a data connection to this XML file and all works fine for first time. But when I change some fields in XML file and reload the form, it doesn't load new data from XML file, it shows old data. When I do the same with a local XML file, located on my hard drive, all works well. But when it's in SPS library, it loads data only one time. What should I do?
