title: How can I get a localized message in a grails GSP tag attribute?
body: <p>In a grails GSP, I want a toolTip to be localized:</p>
  
  <pre><code>&lt;a href="..." title="localizedMessage"&gt;
  </code></pre>
  
  <p>As the toolTip is written in the attribute title, I can't use <code>&lt;g:message&gt;</code> here. Actually I already have a service for localized messages, but when I call it from the GSP, the service's messageSource is null, so getting that to work would be a solution as well.</p>
