Body
<p>I have this directive:</p> <pre><code>app.directive('recursiveListItem', ['$http', 'RecursionHelper', function ($http, RecursionHelper) { return { restrict: 'E', scope: { parent: '=', onNodeClick: '&', }, compile: function (element, attributes) { return RecursionHelper.compile(element); }, template: '<div class="list-group-item-heading text-muted parent "> \ <input type="checkbox" data-ng-click="visible = !visible" id="{{parent.Name}}">\ <label for="{{parent.Name}}">&nbsp;&nbsp;</label>\ <a href="javascript:void(0)" data-ng-click="onNodeClick({node: parent})">{{parent.Name}}</a> \ </div> \ <ul data-ng-if="parent.Children.length > 0" data-ng-show="visible"> \ <li ng-repeat="child in parent.Children"> \ <recursive-list-item data-parent="child" data-on-node-click="onNodeClick"></recursive-list-item> \ </li> \ </ul>', }; }]); </code></pre> <p>and here is the helper:</p> <pre><code>app.factory('RecursionHelper', ['$compile', function ($compile) { var RecursionHelper = { compile: function (element) { var contents = element.contents().remove(); var compiledContents; return function (scope, element) { if (!compiledContents) { compiledContents = $compile(contents); } compiledContents(scope, function (clone) { element.append(clone); }); }; } }; return RecursionHelper; }]); </code></pre> <p>Everything works like a charm, but I don't get my <code>on-node-click</code> to work. For the all the root items the 'callback' works fine, but from there on, all the children won't fire the callback. I think it has something to do with passing the function reference to the next child in the template.</p> <p>I've also tried <code>data-on-node-click="onNodeClick(node)"</code>, but that doesn't work either.</p> <p>Does someone know how to pass the function reference to the child nodes?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
