Build an object having nested entities.Design Pattern <p>I am using Java 1.6</p>

I have an entity structure called 'pnr' which looks like this:</p>

Nested ngRepeat with function call using parent property as parameter displaying wrong lists <p>I've got a nested ng-repeat that displays a seemingly random list of the possible ones I get.</p>
<p>My HTML is like this:</p>

<p>So just update the <code>ng-init</code> function so it populates the people in the house</p>
<p>The function should l... |
