Empty body?

[Manuel Sugawara]

Hi

I'm working in a menu component, similar to the one in the howtos. The
menuItem template looks like:

    <t:content>
      <li>
        <t:if test="isPage">
          <t:pageLink page="prop:page"
class="prop:className">${pageTitle}</t:pageLink>
          <p:else>
            <a href="#" class="${className}">${pageTitle}</a>
          </p:else>
        </t:if>
        <ul>
          <t:body/>
        </ul>
      </li>
    </t:content>

however this template still renders an empty <ul> if there is no body. I
would like to conditionally display the ul depending if there is a body or
not. Something like:

        <t:if test="hasBody">
          <ul>
            <t:body/>
          </ul>
        </t:if>

Now, I have solved this implementing the hasBody method like:

    @Inject
    private ComponentResources resources;

    public boolean getHasBody() {
        Block block = resources.getBody();
        if ("<PlaceholderBlock>".equals(block.toString())) {
            return false;
        }
        return true;
    }

This works but seems a bit flaky. Is there a better way to figure out if a
block is empty?

Regards,
Manuel.
