Hi,
I implemented your version but still I get the same error, if
I have the Google Analytics Code in the head.
Could it be an error with the way I insert the Google
Analytics Code? I do it in the following way.
In my WebPage class I overwrite the following method:
@Override
public void renderHead(HeaderResponse response) {
String script = "var _gaq = _gaq || ...";
response.renderJavaScript(script, null);
}
