I have an XML file which is updated at 4Hz with values from an external process. I have included this xml file into my project, and am attempting to show the constantly updating values in a text box. I have created a System object and set it to load the xml file twice per second, using the AJAX plugin. I then set up text boxes to display the XML values, using Ajax -> on XML completed. But the text boxes only show the initial value, and are not being updated with the subseqent values. What am I missing?
