    <p><strong>EDIT: <a href="http://jsfiddle.net/eJTFe/1/" rel="nofollow">jsFiddle</a> example here.</strong></p> <p>I have a <code>ngRepeat</code> that spawns directives containing <code>iframes</code>. </p> <pre><code>div(ng-repeat='element in elements') ng-switch(on="element.type") a-directive(ng-switch-when="something") another-directive(ng-switch-when="somethingElse") </code></pre> <p>Now, inside the directive I am loading content into the iframe after some event, by doing:</p> <pre><code>$iframe[0].contentWindow.d_contents = "html" $iframe[0].src = 'javascript:window["d_contents"]' </code></pre> <p>Everything works nicely.</p> <p>When I remove one of these elements from the model (in the controller) with something like:</p> <pre><code>elements.remove(object) //using sugarjs, that's not the issue, same behaviour with splice </code></pre> <p>the UI gets updated accordingly, i.e. the element disappear.</p> <p><strong>The problem</strong></p> <p>This works as expected: </p> <pre><code>elements.push(ele1) elements.push(ele2) .. init iframes inside ele1 and ele2 with content .. elements.remove(ele2) </code></pre> <p>Result: <code>ele2</code> disappears from UI, <code>ele1</code> still there with iframe loaded</p> <p>This does not:</p> <pre><code>elements.push(ele1) elements.push(ele2) .. init iframes inside ele1 and ele2 with content .. elements.remove(ele1) </code></pre> <p>Result: <code>ele1</code> disappears from UI, <code>ele2</code> still there with iframe, but iframe content is back to empty, and <code>iframe.load()</code> gets fired. </p> <p>What is happening here? Why is my iframe getting reseted? </p>

    1. COUseful info : When you have 3 elements and you delete the second one, only the third iframe is reloaded.

    2. COYes, it seems removing an element moves the other elements back 1 position and something changes in the directive..

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
