Description

Consider this snippet:
<!-- Generated pushbutton groups -->
#foreach ($group in $form.pushbuttonGroups)
<div class="die-button-group" style="#coordinates($group)">

1. • *##foreach ($groupChild in $group.children)
   • *##if (!$velocityHasNext)#set($turnPaddingOff = 'style="padding-bottom: 0px;"')#end
   • *##if ($groupChild.class.simpleName == "Pushbutton")
   • *#<div $!turnPaddingOff>
   • *#<button type="submit" name="$groupChild.name" value="$groupChild.value" onclick="loadSubsequent()">#label($groupChild.label)</button>

1. • *#</div>
   • *##end
   • *##end
     </div>
     #end

There is an inherent bug. After the first run of the outer foreach, the var turnPaddingOff is still available and will always set in the div tag. There is only one workaround. At the end of the outer foreach you have to set it to ''.

#set should be available as a locally scoped thing in #foreach or other constructs.
