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.
