I have built a simple page following the intro to PHP and the Kendo UI. I have added a detail row using the detailInit method. The combo box populates properly, and I can add associated records as needed. However, when I try to delete them, the call fails. Actually, the item is removed from the sub grid, but when I hit "save changes", nothing happens. I have tried this in Firefox using Firebug, and I can see the GET methods when loading the grid and the data for the sub grid. I can see the POST when the new association between the primary and secondary data types. However, when I hit "save changes", there is no communication with the server. I have followed the instructions in the comments on the blog entry, but am unable to delete. Does anyone have a solution for this problem?
