title: Grails variable request has "+" between words instead of spaces
body: <p>I have the following:</p>
  
  <pre><code>&lt;g:each status="i" var="grade" in="${chooseList}"&gt;
      &lt;div id="grade_${grade}" class="dojoDndItem" dndType="avail"&gt;
          &lt;g:remoteLink action="getMappings" controller="dataManagement" update="mappedSkills" params="[grade:grade.toString()]" id="1"&gt;${grade}&lt;/g:remoteLink&gt;
      &lt;/div&gt;
  &lt;/g:each&gt;
  </code></pre>
  
  <p>When I print out params.grade in my controller, it "looks+like+this" </p>
  
  <p>in other words, the spaces are replaced with "+"</p>
  
  <p>what causes that? Can I get rid of it, or do I have to take care of it from within my controller?</p>
