    Hello,
    Small problem trying to rename News categories from the backend (default provider, SF 3.7.2096, not using nested categories). It is not possible to change the case of letters in the name as it gives an error "Category with the same name already exists!". After that error, if I type an actual new name and click the Update button in the renaming dialog it fails with exception:

    You cannot change a value of an object that is not in transaction.
    Descrizione: Eccezione non gestita durante l'esecuzione della richiesta Web corrente. Per ulteriori informazioni sull'errore e sul suo punto di origine nel codice, vedere l'analisi dello stack.

    Same exception comes up when trying to rename a category two times in a row or renaming two categories in a row, you have to go to any other page and then back to the categories list after every rename in order for it to work.
    Also when these errors come up the listview starts to show a wrong count of items per category (usually shows 0 even if there are items) and it remains wrong until a succesful renaming of the affected category.

    Thanks,
    Alessio

    Hi Alessio S.,

    It is a bug in our code. It comes from UpdateContentCategory method. We will try to sort out the issue for the next SP. Unfortunately I am not able to come up with a temp solution, because the UpdateContentCategory method could not be overridden.

    The error is thrown, because there is CategoriesTree or CategoriesList control on a page and when a category is renamed we are trying to update the reference.
