you might use this for displaying the variables ... not the best but will do the job... you will need to alter the look and feel as required...

<g:evaluate jelly="true">

var set = new GlideappVariablePoolQuestionSet();

set.setRequestID(${ref}.sysapproval.sys_id);

set.load();

</g:evaluate>

<j:forEach var="jvar_question" items="${set.getFlatQuestions()}">

<j:if test="${jvar_question.getDisplayValue() != '' &amp;&amp; jvar_question.getDisplayValue() != null &amp;&amp; jvar_question.getDisplayValue() != 'undefined'}">

<tr>

<td>

${jvar_question.getLabel()}

</td>

<td> ${jvar_question.getDisplayValue()}

</td>

</tr>

</j:if>

</j:forEach>

Hi Kalai,

I need your advice on Need to change approval summarizer for checkbox type variables

Please share your thoughts.

Hi,

I think this is what you want to do:

Write a javascript code to read each item in the macro using id (DOM) to check whether its blank or not, if it is you can hide it using DOM like this

document.getElementById("<id of your field>").style.visibility="hidden";

This code will cone in your ui macro itself inside <script></script> tags.

For this we have to modify below UI macro

approval_variable_summary

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

  <g:evaluate>

                                              var set = new GlideappVariablePoolQuestionSet();

                                              set.setRequestID('${jvar_sc_req_item}');

                                              set.setTaskID('${jvar_sc_task}');

                                              set.load();

  </g:evaluate>

  <table cellspacing="10" cellpadding="0" width="100%" style="background-color: #fffff0;">

                                                              <j:forEach var="jvar_question" items="${set.getFlatQuestions()}">

<!-- Hiding empty variables by Sana -->  

                                                                    <j:if test="${jvar_question.isVisibleSummary()&amp;&amp;jvar_question.getDisplayValue() != ''}">

  <g:summarize_question question="${jvar_question}" />

                                                                    </j:if>

  </j:forEach>

  </table>

</j:jelly>
