Expression Listeners in vaaddin client engine

Hi

I am working on an event based framework. We are planning to move it to VAADIN.
Current framework is using expression listener to handle any change in URL like

addExpressionChangeListener(ivEVA,“hash”,“window.location.hash”);

if any change in hash value in window location, expression listeners and there adapters start exceuting the code.

Is it any expression change listeners are supported by vaadin? if yes, please let us know. If no, then please tell me any other way to handle it.

Thanks
Suri
