title: Hide/show ace:dialog from JSF managed bean
body: <p>I am having difficulty in trying to show an <code>&lt;ace:dialog&gt;</code> dialog from a backing bean class. I have tried to access the dialog box component through the following code:</p>
  
  <pre><code>context.getViewRoot().findComponent("allianceMemberForm:addAlliance:addAllianceForm:selectStartDate");
  </code></pre>
  
  <p>However, I do not know how to hide or show this dialog from within a bean method. How can I achieve this?</p>
