[stringtemplate-interest] Ok, I'm stumped

[Barnes, Jeff]

True dat... This code better illuminates the problem. I guess I better go back and revise some unit tests... ;-)

import org.antlr.stringtemplate.StringTemplate;

public class Test
{
     static class Form {
         String[] names;
         boolean[] values;
         public String[] getNames() { return names; }
         public boolean[] getValues() { return values; }
     }

     public static void main(String[] args)
     {
         Form f = new Form();
         f.names = new String[] { "Terence", "Parr" };
         f.values = new boolean[] { false, true };

         StringTemplate st = new StringTemplate( 
             "$form.names,form.values:{ name, value |\n" +
             "$name$\n" +
             "$value$ " +
             "$if(value)$I'm True$else$I'm False$endif$" +
             "};separator=\"\n\"$");
         st.setAttribute("form", f);
         System.out.println(st.toString());
     }
}

Hi Jeff!

It only appears to do so...

Huh! :)

Using Boolean objects makes this work.
Don't ask my why, but adding $value$ to the $if$ clearly shows that  
the boolean[] is passed
into ST wholesale and the first time evaluates to true (its pointer)  
and the second time the
form.values is exhausted and evaluates to false.

I didn't expect it to do so, either. Ter, is this supposed to work?

cheers,
