Yes, it should work transparently.  If you click on an HtmlButton for 
example, it will fire the onclick handler if available.

For normal use, you shouldn't need to call executeJavaScriptIfPossible 
at all.  It's there if you really need it but the handlers are supposed 
to be called automatically.

The HtmlSelect will execute the onchange handler on changes.  What is 
the problem you're seeing.

It returns a ScriptObject which in turn contains the new page (if one 
was loaded) and the actual result returned by the rhino script engine. 
The documentation has been fixed to reflect this.

FWIW, the javascript support will only work if javascript is enabled. 
If javascript isn't working at all then make sure that js.jar is in your 
classpath and that you haven't disabled javascript support in the WebClient.
