[stringtemplate-interest] Maps vs aggregates vs beans

[Steven Byrnes]

Hi,

I'm running into a problem with aggregates and multi-valued attributes.  Not sure if it's lack of 
understanding on my part or something else... I'm running String Template 2.3b7.

For the following template:

  StringTemplate t = new StringTemplate("$name:{ <b>$it.a$ - $it.b$</b> }$");

if I use 1 or more aggregate attribute calls, it works, e.g.:

  t.setAttribute("name.{a,b}", "foo", "blah");
  t.setAttribute("name.{a,b}", "bar", "brap");

same thing for a simple bean.  One or more setAttributes() will work.

  t.setAttribute("name", new data("foo", "bar"));  // where data() has getA() and getB() methods

If I use setAttribute() for multiple Hashmaps, it works.  But if I only use one, I get an error, e.g.:

  HashMap<String,String> m = new HashMap<String,String>();
  m.put("a", "foo"); m.put("b", "blah");
  t.setAttribute("name", m);
  System.out.println(t.toString());

  =>

  Class java.lang.String has no such attribute: a in template context [anonymous anonymous]
  java.lang.NoSuchFieldException: a
        at java.lang.Class.getField(Class.java:1507)
        at org.antlr.stringtemplate.language.ASTExpr.rawGetObjectProperty(ASTExpr.java:410)
        at org.antlr.stringtemplate.language.ASTExpr.getObjectProperty(ASTExpr.java:314)
  ....

Any ideas?

Thanks,
Steven
