Hi Manuel,
Seems more logical to have the <ul> at the same level as the <li>. That
way you will know if you have generated any <li>.

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.
