Issue with Ng-Messages not functioning properly due to a custom ng-Include directive lacking a child scope

I have created a custom directive called lobInclude, which is similar to ngInclude but with no isolated scope:

.directive("lobInclude", ["$templateRequest", "$compile", function($templateRequest, $compile)  {
        return {
            restrict: "A", 
            scope: false,
            compile: function()  {
                return {
                    pre: function(scope, elem, attrs) {
                        var toObserve = "lobInclude";
                        attrs.$observe(toObserve, function(value) {
                            value = scope.$eval(value);
                            $templateRequest(value, true).then(function(response) {
                                if (angular.isDefined(attrs.replace))
                                    elem.replaceWith($compile(angular.element(response))(scope));
                                else
                                    elem.append($compile(angular.element(response))(scope));
                            });
                        });
                    },
                    post: function() { }
                };
            }
        }
    }]);

Everything seems to be working fine, however, the ng-Messages are not functioning correctly when using my directive. You can view an example here: http://codepen.io/jros/pen/jPxmxj?editors=101

In the provided code pen, there is a form with an input field and my directive that includes a script with ng-template containing another input field.

The ng-messages in the first input field work properly, but not in the included template.

Any suggestions or ideas on how to resolve this issue?

Answer №1

The problem at hand pertains to the compilation of the specified template:

$templateRequest(value, true).then(function(response) {
    if (angular.isDefined(attrs.replace))
        elem.replaceWith($compile(angular.element(response))(scope));
    else
        elem.append($compile(angular.element(response))(scope));
});

Here's the sequence: create an element, compile it, and then add/replace the element in the DOM. While debugging angular.js, it becomes apparent that NgModelDirective is responsible for communicating with the FormDirective controller in order to set attributes like $pristine, $touch, etc. NgModelDirective requires a '^?form' as part of its requirement for communication with the parent form. The issue arises when compiling the element because the template lacks a parent form since it is not yet included in the DOM. As a result, ngModel cannot locate the ancestor form and therefore cannot set attributes like $error, $pristine, $touch, etc.

The solution involves adding the element to the DOM before compiling it:

$templateRequest(value, true).then(function(response) {
    var responseElem = angular.element(response);
    if (angular.isDefined(attrs.replace))
        elem.replaceWith(responseElem);
    else
         elem.append(responseElem);
    $compile(responseElem)(scope)
});

Thank you
