    Nested content as a macro parameter

    Hi!

    Is it possible to use a nested content property as a macro parameter? Like so:

    var items = CurrentPage.GetPropertyValue<IEnumerable<IPublishedContent>>("items");
@Umbraco.RenderMacro("SomeMacro", new {
   items = items
});

    My question is how do I parse the <IEnumerable<IPublishedContent>> to the macro as a parameter?

    This is what I have so far in the macro view (not working):

    var items = Model.MacroParameters["items"] as IEnumerable<IPublishedContent>;
foreach(var item in items) {
 ...
}

    Thanks!!!

    Hi Mathias

    You have to cast macro param like that:

    var items = Model.MacroParameters["items"] as IEnumerable<IPublishedContent>;

    Thanks,

    Hi Alex! Im getting System.NullReferenceException: Object reference not set to an instance of an object. on the foreach line. Does it matter which parameter type items is set to?

    Hi Mathias

    I have an idea, why did you pass CurrentPage field to macro?

    You can use in the macro:

    var items = CurrentPage.GetPropertyValue<IEnumerable<IPublishedContent>>("items");

    Thanks,

    Alex

    Yeah that would work, but I didn't mention that the nested content is a property on another nested content, so CurrentPage is not an option :( 

    var items = OtherNestedContentItem.GetPropertyValue<IEnumerable<IPublishedContent>>("items");
@Umbraco.RenderMacro("SomeMacro", new { items = items});

    My question is how do I parse the <IEnumerable<IPublishedContent>> to the macro as a parameter or if you have another solution to this problem?
