In a nutshell, I have a form used to set up a proprietary, data-driven "slide-show" for our marketing department. One of the aspects of this is that there will be a repeating group, with each instance/node representing the attributes of an individual slide. The stakeholder wants to be able to sort these slides (ostensibly using an index number as a "sort value"), since they might need to be re-arranged after the data is input. From what I've gleaned on this site, it sounds like it MIGHT be possible by editing the view/XLS file, using a combination of xls:sort and Preserve Code block. (I'm trying o convince him to use Filler, but that approach is currently presenting it's own authentication issues when trying to submit on our SPO site.) I have never edited XML in that fashion before, and wold like to know whether the experts here think it's a lost cause (i.e. stick with Filler) or whether it's worth pursuing. Thanks in advance!
