Use the generated method "setTextTeacherName(String)". This sets the content 
of the first descendant of the node with id "teacherName". In your example, 
thats the first child (i.e. the same node you are using), but the difference 
is that "setText....()" doesn't break the template if e.g. the designer 
decides to make the text bold.

That's right. There isn't any child node in this case. Simply add a dummy text 
to the template.

Hope this helps,
