    <p>I am using Spring-WS to populate a <code>List&lt;SomeBean&gt;</code> w.r.t. a web-service. The final list that I get after consuming the service contains <code>null</code> entries for some of its properties. For example, consider the following list of <code>MangaBean</code> which has title, author and genre as properties.</p> <pre><code>MangaBean [title=Bleach, author=Kubo Tite, genre=fantasy] MangaBean [title=Naruto, author=Masashi Kishimoto, genre=action] MangaBean [title=One Piece, author=Eiichiro Oda, genre=null] MangaBean [title=Fairy Tail, author=Mashima Hiro, genre=null] MangaBean [title=Rurouni Kenshin, author=Watsuki Nobuhiro, genre=Shounen] MangaBean [title=Takamagahara, author=KAWAI Juuzou, genre=Supernatural] MangaBean [title=Historys Strongest Disciple Kenichi, author=Matsuena Syun, genre=Martial arts] MangaBean [title=Hajime no Ippo, author=Jyoji Morikawa, genre=null] </code></pre> <p>The <code>genre</code> entry for some beans are <code>null</code>. I am trying to remove the objects with <strong>null properties</strong> in the list. My questions are:</p> <ol> <li>Is it proper/good practice to alter the original list by removing specific entries? Or should I populate another list w.r.t. the previous list?</li> <li>If I should alter the list and remove those null entries, how should I do it?</li> </ol> <p>I tried <a href="https://stackoverflow.com/questions/4819635/how-to-remove-all-null-elements-from-a-arraylist">this</a> but it fails as the object-refs themselves aren't null. I tried the traditional for loop but it fails to remove adjucent objects with null properties. Cannot use the enhanced-for-loop for removing items while accessing the list. Kindly render me some brain. :)</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.
