Questions

Hello,

I have Macro :

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@{
    int contentId = Int32.Parse(Model.MacroParameters["ChooseContent"].ToString());
    var node = Umbraco.Content(contentId);
}
@node.GetGridHtml("content")

ChooseContent is Content Picker, all works fine in Front Page. But if i allow to “Render in rich text editor and the grid”, then i BackOffice I got :

System.InvalidOperationException: Cannot render a macro when there is no current PublishedContentRequest.
