The above code works in the sense that there
are no errors thrown. Clicking on the link
for my controller method 'widgettest' renders
the page with title and the text in the div
that is supposed to be replaced. But no JS
action occurs onscreen. :{
PS.
There is nothing in the rendered page's
source <head> section resulting.
Putting the code below into the template works
in so far as it appears if I View Page Source.
However, nothing happens, the JS does not
appear to run.
<script type="text/javascript" src="${tg.url('/js/chart.js')}"></
script>
</head>
