Re: using hyperlink to process commands?

History, History tokens, links and ValueChangeHandler work hand in hand to provide psuedo navigation within the client code. The Google GWT docs cover all these in detail and offer numerous code samples too.

In short, add a history token can procedurally be added to History causing the url in the browser to change to reflect the token in the form of #valueoftoken. In conjunction with this, your value change handler is notified of the history changed state passing the token in a ValueChangeEvent object. Your code can then process the event notifications and act accordingly. Links are a declarative way of changing the history state and also cause value change events to be fired so you can use either of these patterns in your application.

The commands should open some panels, so they are on the client.

I want to present a list of items, and one click on one item should
open the details.

Can you please describe your method with the History tokens?

Thanks
