I have a problem with this code, any help is appreciate the error code is Object reference not set to an instance of an object. I try to get the value from a document types from home page and put in masterpage.

IPublishedContent homePage = Model.Content.AncestorOrSelf(1); IPublishedContent currPage = Model.Content; Pagehome headerHomePage = currPage.Descendant

int headerType = (headerHomePage.HeaderHomeType == null) ? -1 : (int)headerHomePage.HeaderHomeType; string headerTypeStr = (headerType == -1) ? "Static Sticky" : umbraco.library.GetPreValueAsString(headerType);

switch (headerTypeStr)
{
    case "Transparent":
        headerHomeClass = "transparent-header";
        headerDataClass = "data-sticky-class='not-dark'";
        break;
    case "Semi Transparent":
        headerHomeClass = "transparent-header semi-transparent";
        break;
    case "Left Side":
        headerHomeClass = "no-sticky";
        break;
    case "Right Side":
        headerHomeClass = "no-sticky";
        break;
    case "Floating":
        headerHomeClass = "transparent-header floating-header";
        break;
    case "Static Sticky":
        headerHomeClass = "static-sticky";
        break;
    case "Alternate Logos":
        headerHomeClass = string.Empty;
        break;
    default:
        headerHomeClass = string.Empty;
        break;
}

Hi Davide,

I think headerHomePage can be null.

Can you share all code?
