RML repeatIn on empty list

Asked by OpenBMS JSC

Hi,

I want to loop over a custom list generated by the custom report object, something like repeatIn(get_lists(o),'c'). The trouble is when get_lists(o) return an empty list ([]), the this generate exception in RML.

What should I do to get around this?

Many thanks.

I've found it myself. I'll share it here, just in case someone will run into the same problem. The idea is to wrap the test in a <para> under a <section>.

        <section>
          <para style="P10"><font color="white">[[ get_lists(o) or removeParentNode('section') ]]</font></para>
          <blockTable colWidths="141.0,122.0" style="Table9">
            <tr>
              <td>
                <para style="terp_default_9">[[repeatIn(get_lists(o),'c') ]]</para>
              </td>
...
          </blockTable>
        </section>
