+ * <p>Defaults to <code>true</code> to defer the initial refresh of the view.</p>

+ * by the expensive update of the view structure.</p>
+ * <p><b>Important: </b>Be aware that this will mean that the View's item elements will not be available immediately upon render, so
+ * <i>selection</i> may not take place at render time. To access a View's item elements as soon as possible, use the {@link #viewready} event.
+ * Or set <code>deferInitialrefresh</code> to false, but this will be at the cost of slower rendering.</p>
