[stringtemplate-interest] cannot embed template anonymous in itself

[Stevenson, Todd (GE Healthcare, consultant)]

I don't understand the restrictions in StringTemplate that won't allow
me to build a template that is recursive in nature.  The code where this
is failing looks like this code.  It recursively builds a tree until
there are no child nodes left.  However StringTemplate throws an
exception not allowing this recursive method call.  
 
Any ideas?
 
public StringTemplate printTree() {

    StringTemplate st = new StringTemplate("$parent$\n
$child;separator=\"\n\"$\n");

    st.setAttribute("parent", parent.toST());

// print all your child nodes

    MyNode curr = this.child;

    while (curr!= null) {

        st.setAttribute("child", curr.printTree());

        curr = curr.sibling;

    }

    return st;

}
