Jelly: Glide Evaluate Tag Variable

jancaasi · ‎10-14-2015

Hi Everyone,

I have a bit of a problem with passing variables in the evaluate tag. Below is the script:

   <g:evaluate var="jvar_gr" object="true">
         var gr = new GlideRecord('xxxx_database_view');
         gr.query();
         gr;
   </g:evaluate>

   <j:if test="${jvar_gr.hasNext()}">
           <j:while test="${jvar_gr.next()}">
           <tr>
                 <td>${jvar_gr.getValue('xxx_employee')}</td>
                 <td>${jvar_gr.getValue('xxx_dateinput')}</td>
                 <td>${jvar_gr.getValue('xxx_hours')}</td>
                 <td>${jvar_gr.getValue('xxx_activity')}</td>
                 <td>${jvar_gr.getValue('xxx_description')}</td>
                 <td>${jvar_gr.getValue('yyy_team')}</td>
           </tr>
           </j:while>
   </j:if>

If I don't use the var="jvar_gr" in the evaluate tag and just continue on with the glide record script that I usually use, it works. Its returning the records that I want to return.

I tried adding an alert script after line 6 and the alert script is working. But when I tried putting the alert script between line 7 and 8, the alert script isn't working and I'm guessing that there's something wrong with the variable jvar_gr. Can someone tell me what's wrong with my code?

Hi Jan,

Sure, no problem.

The variable you set to store the new gliderecord, is the name you should set in the g:evaluate tag. In your case your set the var as gr; it's recommended to use something logical, like I did with the table name, to avoid confusion.

I would write your code like the following:

<g:evaluate var="incident" object="true">


   var incident = new GlideRecord("incident"); // mark this the same name as your g_evaluate variable name


   incident.addQuery("active", "true");


   incident.query();


   incident; // this is the variable put into the variable jvar_gr


</g:evaluate>

The jvar prefix, is in the wiki; but I believe that's for back-end queries, rather than front-end. I suspect it doesn't always mix well. I have never had it work, tbf. The way I described is how it always works for me. Not declaring the variable can and will lead to some odd results, so I do recommend declaring it.

I keep hitting submit, before I'm ready to answer fully, apologies. Its 2am here.
