    call RenderMacroContent() from base error

    API Questions

    I am using umbraco  v 4.11.6 and try to create a base extension to return some html code to a ajax call.

    However, I encounter the follow error 

    UmbracoModuleUmbraco request begins

    contentError loading MacroEngine script (file: empty.cshtml)

    This is the code trigger the error 

    HttpContext.Current.Trace.Write("content", umbraco.library.RenderMacroContent(node.GetProperty("bodyText").Value, pid));

    empty.cshtml contains two statement only

    @inherits DynamicNodeContext
    @using umbraco.MacroEngines

     

    If I change bodyText to some static text, the base extension work fine. 

    Is it a bug or somthing?

    Thanks for help.

    looks like you are hitting the current page/node issue

    http://labs.vertic.com/2012/05/01/rendering-umbraco-4-content-in-a-service/

    just make sure you set the page id first

    calling 

    int nodeId = 213;
                var razorRendered = umbraco.library.RenderMacroContent("<?UMBRACO_MACRO macroAlias=\"ContentMacroLoader\" runat=\"server\" ColumnName=\"Left Column\" ></?UMBRACO_MACRO>", nodeId);

    always comes back with an error until I added

                int nodeId = 213;
                var contentPage = new umbraco.presentation.Web.UI.ContentPage();
                contentPage.UmbracoNodeId = nodeId;
                var razorRendered = umbraco.library.RenderMacroContent("<?UMBRACO_MACRO macroAlias=\"ContentMacroLoader\" runat=\"server\" ColumnName=\"Left Column\" ></?UMBRACO_MACRO>", nodeId);

    Which seems a bit mad but totally works !

    Thank you rob for providing this answer.

    I agree, it seems mad, but it does the job.
