Re: firing httprequest multiple times

Disable the widget during processing (which sinks/unsinks the click event). 

Hyperlink doesn't have this functionality per default, but you can use an other widget like a button that does have this.

You could extend the HyperLink widget and add a enabled property.

Almost all my widgets implement a HasEnabled interface that have this enabled property per default.

In the OnClick you will call widget.setEnabled(false)

In the OnResponseReceived call you will call setEnabled(true).
