title: How to make p:selectOneMenu show current value?
body: <p>I have a <code>&lt;p:selectOneMenu&gt;</code> to choose the category for an item from. By default the menu displays the first entry of <code>someBean.selectedParty.categories</code> as selected. But the item already has a current category at <code>someBean.selectedItem.category</code> that I want to be displayed/selected. How can I achieve that?</p>
  
  <pre><code>&lt;p:selectOneMenu value="#{someBean.selectedItem.category}" converter="omnifaces.SelectItemsConverter"&gt;
      &lt;f:selectItems value="#{someBean.selectedParty.categories}" var="category" itemLabel="#{category.name}"/&gt;   
  &lt;/p:selectOneMenu&gt;
  </code></pre>
