>             Project: Velocity
>          Issue Type: Bug
>          Components: Engine
>    Affects Versions: 1.1
>         Environment: Operating System: Solaris
> Platform: Sun

> The velocity user's guide states:
> --------8<---------------------
> Velocimacros can take as arguments any of the following VTL elements : 
> Reference : anything that starts with '$' 
> String literal : something like "$foo" or 'hello' 
> Number literal : 1, 2 etc 
> IntegerRange : [ 1..2] or [$foo .. $bar] 
> ObjectArray : [ "a", "b", "c"] 
> boolean value true 
> boolean value false
> "
> ----------8<---------------------
> So I constructed the following macro:
> #macro(getIcon $name $num)
> ## int gets converted to string when passed
> #if ($num > 0)
> 	icon-${name}-on.gif
> #else
> 	icon-${name}-off.gif
> #end
> #end
> ... and called it like this:
> #getIcon( 'mail' ${numMail} )
> ... where $numMail was an Integer object with a value greater than zero
> in the macro, it always thought $num was null.
> until I did this:
> #getIcon( 'mail' $numMail )
> .. then it worked.
> The formal notation didn't work, even though the doc says:
> " Reference : anything that starts with '$' "
> Either the doc should clarify or the behaviour should be fixed to include 
> formal notation.
