[JXTemplate] Sum values inside

[Antonio Gallardo <ag...@agssa.net>]

Hi:

I am trying to get the sum of some values inside 2 <jxForEach>. Here is
the code:

<jx:set var="total" value="${0}"/>
<jx:set var="costo" value="${0}"/>
<jx:forEach var="activity" items="${bean.planActivityList}">
  <jx:forEach var="item" items="${activity.planCostList}">
    <jx:set var="total" value="#{item.pco_total + $total}"/>
    <jx:set var="cost" value="#{item.pco_cost + $cost}"/>
  </jx:forEach>
</jx:forEach>
<td><jx:formatNumber value="#{$total}"/></td>
<td><jx:formatNumber value="#{$cost}"/></td>
<td><jx:formatNumber value="#{$total - $cost}"/></td>

The problem is that this always return 0 values.

What I am doing wrong?

Best Regards,

Antonio Gallardo

Try this:

<jx:set var="total" value="${0}"/>
<jx:set var="cost" value="${0}"/>
<jx:forEach var="activity" items="${bean.planActivityList}">
  <jx:forEach var="item" items="${activity.planCostList}">
    <jx:set var="total" value="${item.pco_total + total}"/>
    <jx:set var="cost" value="${item.pco_cost + cost}"/>
  </jx:forEach>
</jx:forEach>
<td><jx:formatNumber value="${total}"/></td>
<td><jx:formatNumber value="${cost}"/></td>
<td><jx:formatNumber value="${total - cost}"/></td>


or if you insist on using XPath:

<jx:set var="total" value="#{0}"/>
<jx:set var="cost" value="#{0}"/>
<jx:forEach var="activity" items="#{bean/planActivityList}">
  <jx:forEach var="item" items="#{$activity/planCostList}">
    <jx:set var="total" value="#{$item/pco_total + $total}"/>
    <jx:set var="cost" value="#{$item/pco_cost + $cost}"/>
  </jx:forEach>
</jx:forEach>
<td><jx:formatNumber value="#{$total}"/></td>
<td><jx:formatNumber value="#{$cost}"/></td>
<td><jx:formatNumber value="#{$total - $cost}"/></td>


But if your data consists of Java beans (as in this case) I recommend 
you stick with Jexl as the expression language.
