How can I get the length of Array ?

[trad-ex <tr...@inter7.jp>]

Hi all,

In the Velocity realm, how can I get the length of Array ?
For instance,

#set( $arr = __set int[] value__ )
#if( $arr.length > 0 )
 ...(snip)...
 
$arr.length is always null. Why ?
I always use helper Object to avoid this issue.
For example, 

$helperObj.lengthOf( $arr )

This method, lengthOf, is described below:

 public int lengthOf( Object[] objects )
 {
   if( objects == null)
     return 0;
   return objects.length;
 }
 
Best Regards,
trad-ex
