I created a new data type to use as a parameter in my macro. It is a Rich Text Editor data type, so I can have text with a link in it. Here are my files:

Text Editor HTML

<div ng-controller="Macro.texteditor">
    <ng-form>
        <umb-editor model="textInput"></umb-editor>
    </ng-form>
</div>

Text Editor Controller

angular.module("umbraco")
.controller("Macro.texteditor",
function ($scope) {
$scope.textInput = {
    label: 'bodyText',
    description: 'Load some stuff here',
    view: 'rte',
    value: $scope.model.value,
    config: {
        editor: {
            toolbar: ["bold", "italic", "link"],
            stylesheets: ["Editor"],
            dimensions: { height: 400 }
        }
    }
};
$scope.$watch('textInput.value', function (newValue, oldValue) {
    $scope.model.value = newValue;
});
});

Package Manifest

{
propertyEditors: [{
alias: "TexteditorDataType",
name: "Text Editor",
isParameterEditor: true,
editor: {
view: "~/App_Plugins/MacroDataTypes/texteditor.html"
}
}],
javascript: [
"~/App_Plugins/MacroDataTypes/texteditor.controller.js"
]
}

Macro Partial (abridged

@{
    var div1Body = Model.MacroParameters["paragraph1"].ToString();
}
<div class="feature-body">
    @Html.Raw(div1Body)
</div>

When I add this macro to a page using the Rich Text Editor, I get the following error message:

Request error: The URL returned a 404 (not found): /umbraco/backoffice/UmbracoApi/Macro/GetMacroResultAsHtmlForEditor

The error seems to be related to putting a link in the RTE provided by the macro. If I remove the link, the macro renders correctly in the page RTE.

It still saves correctly and renders in the browser, but I'd like to eliminate the error in the back end if possible. I don't want my client to see error messages that might confuse him.
