Simply said: I made a simple dashboard to show some nodes in a table view. There's a button in each row for editing that node. The button uses the following function to open an editor:

 function showOrderDetails(id, name) {
    var options = {
        id: id
    };
    editorService.contentEditor(options);
}

This works fine, except for the mntp-properties of the node. Inside these mntps there is a Xpath expression to get startnode:

$current/ancestor-or-self::shop/descendant-or-self::shopSettings/descendant-or-self::shippingMethods

But this causes an exception (in the background) because $current is not available:

Possibly unhandled rejection: {"errorMsg":"Failed to retrieve entity data for query $current/ancestor-or-self::shop/descendant-or-self::shopSettings/countries","data":{"Message":"The request is invalid.","MessageDetail":"The parameters dictionary contains a null entry for parameter 'nodeContextId' of non-nullable type 'System.Int32' for method 'Umbraco.Web.Models.ContentEditing.EntityBasic GetByQuery(System.String, Int32, Umbraco.Web.Models.ContentEditing.UmbracoEntityTypes)' in 'Umbraco.Web.Editors.EntityController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter."},"status":400}

The url that is causing the 400 error is:

/umbraco/backoffice/UmbracoApi/Entity/GetByQuery?query=%24current%2Fancestor-or-self%3A%3Ashop%2Fdescendant-or-self%3A%3AshopSettings%2Fdescendant-or-self%3A%3AshippingMethods&nodeContextId=undefined&type=Document

As you can see nodeContextId=undefined seems to be going wrong here...

So, when editing the node from the content tree (the regular way) it works fine with mntps with xpath for startnode, but when using editor.contentEditor inside the custom dashboard plugin it doesn't.. Is this a bug? Or does anyone know what I should do to fix this? Any help would be really appreciated.
