Error loading MacroEngine script (file: NewsletterSubscribe.cshtml)

Hi, In Umbraco 7.4.1 we get an error loaing NewsletterSubscribe.cshtml. This happens even if we remove all the code from the file. I suspect that the macro parameter type "Newletter Studio Mailing List Picker" depends in the Microsoft.Web.Helpers.dll file which was removed i Umbraco 7.3.0. I have tried copying the file back, but that totally crashed the Umbraco site. I get the following stack trace in my log file:

Hi!

Thanks for sharing this!

We need to take some time to try to figure out why but could it just be that we have some old using-references in the .cshtml-file that we ship? Do you mind having a look at that?

Ok, having another look at it, this is not an issue with Newsletter Studio. It seems like Umbraco has an issue viewing macroscripts. Seems like changing this to a partial macro will do the trick. I'll also check the issue-tracker to see if this issue is reported or fixed.

Hi!

Thanks for the heads up!

We'll have a look to see if we can ship with a partial in the future.

Hello, Ole.

I had the same issue a week ago and wound up creating the macro partial myself.

Here it is if you haven't already gotten around to it. FYI, the markup is using the Foundation grid framework and Font Awesome.

@inherits Umbraco.Web.Macros.PartialViewMacroPage

@{
    var showThankYou = false;
    var error = "";

    if (Request.Form["action"] != null && Request.Form["action"] == "subscribe" && Request.Form["txtEmail"] != "")
    {
        var txtEmail = Request.Form["txtEmail"];

        if (NewsletterStudio.Api.IsValidEmail(txtEmail))
        {
            // Trying to get the subscriptionId from Macro-parameter.
            var subscriptionId = (Model.MacroParameters["SubscriptionId"] != null) ? Convert.ToInt32(Model.MacroParameters["SubscriptionId"]) : 0;

            // Adding subscriber
            var success = (subscriptionId != 0) ? NewsletterStudio.Api.Subscribe(txtEmail, subscriptionId) : NewsletterStudio.Api.Subscribe(txtEmail);

            showThankYou = true;
        }
        else
        {
            error = "* Please enter a valid e-mail";
        }
    }
}

@if (!showThankYou)
{
    <form method="post" action="@Request.Url" style="max-width: 420px;">
        <input type="hidden" name="action" value="subscribe"/>
        <div class="row collapse">
            <div class="small-9 columns">
                <input type="text" name="txtEmail" id="txtEmail" placeholder="My Email Address"/>
            </div>
            <div class="small-3 columns">
                <button type="submit" id="btnSubmit" class="button postfix">Subscribe</button>
            </div>
        </div>
        <div style="color: Red">@error</div>
    </form>
}
else
{
    <p class="panel success">
        <i class="fa fa-thumbs-up"></i> You have successfully subscribed to the Office of Research Newsletter.
    </p>
}

Thanks, Matthew. We've already got this up and running, but this is nice to have if others should have the same issue.
