Google Analytics in Activiti-Explorer

[onlinesun]

I tried to add Google Analytics to Activiti-Explorer, but it never showed up, I tried to add the code into ExplorerApplicationServlet.writeAjaxPageHtmlVaadinScripts:

String googleAnalytics = "xxxxxxx"; //Google Analytics generated code
page.write(googleAnalytics);

But it doesn't work. I searched the Vaadin forum, there is an add-on for google analytics. Is there a simple way to add the analytics code other than downloading the vaadin analytics add-ons?

Hmm it seems that the addon is the easiest. It probably takes quite a bit of Vaadinmagic to get that custom js into the index page.

OK I'll try the add-on then.
So, does that mean if I want to add a Javascript library like JQuery, I need to write some client code and recompile widgetsets? Thanks.
