Here's my velocity.properties:

# NOTE: Change cache settings to set to false while developing - change to true
when deploying to production.
# You'll need to copy this entire file into WEB-INF/classes to override any

# for the loader we call 'class', use the ClasspathResourceLoader

> From: mraible <[EMAIL PROTECTED]>

> Subject: Issue with $velocityCount in 1.5
> To: [email protected]
> I've been using Velocity 1.4 for a couple of years now with great success.
> Today, I tried to use Struts Menu 2.4.2 with Velocity 1.5 and found an issue
> with $velocityCount not being properly processed. My template is below.
> The problem occurs on the following line:
> #if ($velocityCount == $menu.parent.components.size())
> <li class="last">
> #else
> With 1.4, $velocityCount turns into a number when the displayCssMenu macro
> is called from #foreach. However, in 1.5, it's never turned into a number.
> Any ideas?
> Thanks,
> Matt
> #macro( displayCssMenu $menu )
> #if ($displayer.isAllowed($menu))
> ## set menu title
> #set ($title = $displayer.getMessage($menu.title))
> #if (!$menu.url) #set ($url="javascript:void(0)") #else #set
> ($url=$menu.url) #end
> ## create a single menu item
> #if ($menu.components.size() == 0)
> #if ($velocityCount == $menu.parent.components.size())
> <li class="last">
> #else
> <li>
> #end

> $url ${title}
