[stringtemplate-interest] Issue with Multi-Valued attributes where the attribute is a Map Key/Value pair.

[Robert Paterson]

Hi,

I have a problem with a template that uses a Multi-Valued attribute where
the attribute instances are HashMap Key/Value pairs. If I have two or more
HashMap instances the template works fine, but if I only have a single
HashMap instance it tries to iterate through the values of the HashMap. Is
there anyway around this short of creating a proper aggregate object that
has the properties I'm trying to set in the HashMap? (I imagine
StringTemplate is seeing the individual HashMap as a collection).

I have a main template "document.st" as follows:

DOCUMENT {

   CONTENT {

     $Paragraphs:paragraph(); separator="\n\n"$

   }
 
}


And "paragraph.st" as follows:

PARAGRAPH {
  BULLET        "$it.Bullet$"
  INDENT        "$it.Indent$"
  TEXT          "$it.ParagraphText$"
}


And if I use the following code:

    StringTemplateGroup group = new StringTemplateGroup("MyGroup",".");

    // If I set the "Paragraphs" attribute with two HashMap instances it
works.
    StringTemplate docOut = group.getInstanceOf("document");

    HashMap para = new HashMap();
    para.put("Bullet","N");
    para.put("Indent","N");
    para.put("ParagraphText","Now is the time for all good men...");

    docOut.setAttribute("Paragraphs", para);

    para = new HashMap();

    para.put("Bullet","N");
    para.put("Indent","N");
    para.put("ParagraphText","... to come to the aid of their party.");

    docOut.setAttribute("Paragraphs", para);

    System.out.println(docOut.toString());


I get:

DOCUMENT {

   CONTENT {

     PARAGRAPH {
       BULLET        "N"
       INDENT        "N"
       TEXT          "Now is the time for all good men..."
     }

     PARAGRAPH {
       BULLET        "N"
       INDENT        "N"
       TEXT          "... to come to the aid of their party."
     }

   }
 
}

But if I try:


    // But if I only set it with one HashMap instance it fails, and instead
tries to iterate through the values of the HashMap.
    docOut = group.getInstanceOf("document");

    para = new HashMap();
    para.put("Bullet","N");
    para.put("Indent","N");
    para.put("ParagraphText","Now is the time for all good men...");

    docOut.setAttribute("Paragraphs", para);

    System.out.println(docOut.toString());

I get:

   }
 
}



Any help appreciated, but I'll happily write my own proper aggregate object
