title: Pass parameter value by apending/updating string in Multiselect parameter
body: <p>I am new to Pentaho BI tool (pentaho-cde). I want to update selected values and assign to parameter.</p>
  
  <p>I have created Multiselect component and simple parameter.</p>
  
  <p>I have added javascript code in post change methode of Multiselect component as ,</p>
  
  <pre><code>function(s){
  alert(s); // selected values = "08-01-2013,08-02-2013"
  var appendval = s+",08-05-2013"; //after append "08-01-2013,08-02-2013,08-05-2013"
  var  arrayappend =  appendval.toString().split(","); 
  arrayappend = "'" + arrayappend.join("','") + "'";
  if (typeof arrayappend == 'string') arrayappend = [arrayappend];
  alert(arrayappend);  // alert as = '07-29-2013','08-01-2013','08-05-2013'
  //Dashboards.fireChange('solddate',['07-29-2013','08-01-2013','08-05-2013']);//this works 
  Dashboards.fireChange('solddate',arrayappend); // but this is not working
  }
  </code></pre>
  
  <p>As I mention there in firechange event if i passed value directly it will works but if i passed value through array then it will not works, I dont know what i am missing. Thanks in advance. </p>
