I am trying to display a basic PivotMatrix widget inside a web view, and it loads and reads all the data perfectly from the database, but after I try to change the order of the culumns or anything inside the PivotMatrix widget, it starts loading and freezes the whole page. Under network i see that he tries to call a GET url request without any parameters or any body of the request. Is this some kind of a bug or am I doing something wrong?
