    Error during creation of a news.

    I have a problem with your AutoFolders package.
    I'm using:
    Umbraco v4.0.2.1 v.2.0
    Windows Vista with IIS7
    Stacktrace: at the end of this post
    AutoFolders v1.2

    The autofolders.config file is:

    <?xml version="1.0" encoding="utf-8" ?>
              <FolderProvider alias="DataFolder
                   <Property alias="FolderDocType">News</Property>
                   <Property alias="YearFormat">yyyy</Property>
              <DocType alias="NewsItem" folderProvider="DataFolder"/>

    I created a node called "News" (doctype "News")
    This node will contain all the "NewsItems" (doctype "NewsItem")
    When I create a new NewsItem, automatically AutoFolders must create a folder with the year as name and move the NewItems into this folder.
    Well...When I try to do this, I receive this error:

    Object reference not set to an instance of an object.
    System.NullReferenceException: Object reference not set to an instance of an object.

    Can you help me please?
    Thank you

    Hi Adriano,

    Month format is not optional. You need to choose and include a month format

    <Property alias="MonthFormat">MM</Property>

    Hope this helps,
