title: UI Message default value in Liferay portlet
body: <p>Does anybody know, if in Liferay is possibility to use default value in ui message ? I mean I have two files .properties with translations, for example: en.properties:</p>
  
  <pre><code>welecome=Hallo everybody
  someKey=
  </code></pre>
  
  <p>,and default.properites</p>
  
  <pre><code>welecome=Hallo everybody
  someKey=value of some key
  </code></pre>
  
  <p>I want to achieve, that if I use:</p>
  
  <pre><code>&lt;liferay-ui:message key="welcome" /&gt;
  &lt;liferay-ui:message key="someKey" /&gt;
  </code></pre>
  
  <p>with English language (where there is no translation for key 'someKey'), the displayed value will be:</p>
  
  <pre><code>Hallo everybody
  value of some key
  </code></pre>
  
  <p>I mean, when there is no translation for some key, liferay portlet will use value from default properties file.</p>
  
  <p>regards</p>
