Hello, i get a bug when you créate a relational parent list to a child list, and you hope créate a relational view of these two list, after the page render the list and you select any one ítem in the parent list the position index selector of the child list don't match the correlative second ítem, seems that index is not begin in cero, or is add one to the primary index.
I have a sharepoint 2013 RTM, SQL2008R2 and spanish language pack installed.
