    PdfMvcHelperExample.cshtml resulting in 'Object reference not set to an instance of an object 'Error

    Hi

    I have installed PDF Creator on UaaS, and I am able to create PDF documents using the old-style .master templates.

    I would however like to use a .cshtml template and have hence found the Example-MVC-templates-for-PDF-Creator.zip file at: http://our.umbraco.org/FileDownload?id=7068

    The non-helper based templates work fine, but when I try to use the helper template I have two problems

    1. The template includes '@using PdfHelper' which will not compile. I can take it out and then i can un the website in debug mode, but

    2. If I remove the '@using PdfHelper' line I get an 'Object reference not set to an instance of an object' Error tied to the first call of the helper methods:

    enter image description here

    Any ideas?

    Hi Andreas,

    To me it looks like the web.config in your /Views folder doesn't contain the references required to access @Html...

    Could you post that file? and I'll compare to my working example.

    Thanks.

    This looks like the web.config from the root of your application - i need to take a look at the one in the Views folder.

    Sorry, here it is:

    <?xml version="1.0"?>

    Enabling request validation in view pages would cause validation to occur
    after the input has already been processed by the controller. By default
    MVC performs request validation before a controller processes the input.
    To change this behavior apply the ValidateInputAttribute to a
    controller or action.

    Could you try add:

    @using System.Web.Mvc

    To the top of the file.

    Thanks. Darren.

    Hi Darren

    Thanks, whis may be part of the solution, but there are still a couple of issues.

    1. I no longer seem to have access to the @Model object - which is not critical to me.

    2. I seem to get the same error (see below) everytime @Html.Raw is used:

    Best regards, Andreas

    Hi Andreas - Could you post the whole stack trace please. I'm on holiday/vacation this week, so my response may not be so prompt.
