Re: Mouse tracking with Tapestry

Ok,

So finally I could transform my JS libraries into modules and now
everything is super-modular.

I also replaced mousemove by mouseover because it is less demanding.

When Tapestry 5.4.2 is released and "Invoking server-side event handler
methods from JavaScript" is available, I will replace the ZoneUpdater by
this kind of call.

Everything is running well, so now I am working in the cache, but that
is out of the scope of this question.

Thank you all for your help
