I find this extremely surprising, given the ubiquity of this basic syntax among most languages. ## This works as expected: #set ($lastIndex = $list.size() - 1) #set ($last = $list.get($lastIndex)) <p>$last</p> -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@velocity.apache.org For additional commands, e-mail: dev-h...@velocity.apache.org
