I was going through the samples, and I noticed that I couldn't find the source of the data in the samples. The files used are DataA.xml and DataB.xml, however, there is no Data Connection defined anywhere, or at least I can't find it. However, if I delete the xml files, an error shows, so it's obviously using them, somehow.
Also there is no info in the Data View tab, and when I create a new Data Connection, there is always something there.
Thanks!.
