Range operator

[이기동 <br...@3rsoft.com>]

Hi, 
I'm new to velocity.

I have a question about range operator.
This code is working

    #foreach ($i in [1..10])
      $i
    #end

But, that code is not working

    #foreach ($i in [1..$var])
      $i
    #end

and I set $var to 10.

How do I work this code?

Thanks in advance.

That won't work.  We don't do type casts from strings :)

do 

context.put("var", new Integer(10) );

I set value of $var in doBuildTemplate() method of Index.java source like this.

context.put("var", String.valueOf(10));

$var is substituted well outside the #foreach loop, 
but it's not in #foreach statement.

The following example works :

#set($var = 10)

#foreach($i in [1..$var])
$i
#end

(I just tried it :)

Take a look at your template again to make sure that all is well - if
you still have a problem, send us your tempalate so we can take a look.
