    Hi Pinal

    I suspect it's because there is no @CurrentPage...I must admit that I'm not very fluent at Razor yet but I think you should do this...

    var currentPage = @Model;

    and then cal the currentPage variable like @currentPage.Id.

    Does this help?

    I dont think @CurrentPage should be an issue because I am using it very often. Most like it was introduced in U4.11 (http://our.umbraco.org/documentation/reference/mvc/views)

    FYI - I am using MVC views and not umbraco macros.

    @Model does not works with MVC views.

    Hi Pinal

    Yes, my bad - Having a hard time keeping up with all the nice new stuff we get to explore :) Just stumpled across Shannon's blogpost about it. My bad!

    I will try to wrap my head around it and see if I figure something out.

    Hi Pinal

    I think I've been mistaken about the error. Seems to me you're missing () after the NiceUrl() on this line: @ebod.NiceUrl

    Try writing: @ebod.NiceUrl()

    Does this help? :)

    Thanks Jan.

    Nopes ebod.NiceUrl is also not an issue. I am aware of NiceUrl() issue with 4.11.1.  

    Btw in above code "ebod" is an object of my custom class "eBook" and I have string property NiceUrl defined in that class.
