Just put this logic in the render method - it has access to the parameters. If
you want wrapping, call wrap(), otherwise call main(). e.g.
<%args>
$.type
</%args>
<%class>
method render {
if ($.type eq 'ajax') {
$.main(); # skip wrapping
}
else {
$.wrap(); # do wrapping
}
}
</%class>
Here I've moved the render method into a <%class> section since it has more
than a few lines of Perl.
