Hi,

I've added a package: "Pier-JQuery" to the repository: "Pier 2 Add-Ons" (http://source.lukas-renggli.ch/pier2addons) The package contains a single class PRJQuerySearchWidget. PRJQuerySearchWidget, should be a JQuery drop in replacement for PRAjaxSearchWidget (which used Scriptaculous libraries)

The widget depends on JQuery and JQWidgetBox-FormExample-* 
To download the prerequisits:

Gofer new
squeaksource: 'JQueryWidgetBox';
package: 'JQWidgetBox-Core';
package: 'JQWidgetBox-Dev';
package: 'JQWidgetBox-FormExample-Core';
package: 'JQWidgetBox-FormExample-Dev';
load.
JQWidgetExample initialize.

or: 

((Smalltalk at: #ConfigurationOfJQueryWidgetBox) project version: '1.0')
load: 'JQWidgetBox-FormExample-Core';
load: 'JQWidgetBox-FormExample-Dev'.


It's working well for me, let me know if there are any problems including it in other projects

Cheers

Nick
