Hi Dario,
I think you need to specify specifically what add-ons you want to load - PRAjaxSearchWidget is in the group 'Pier-jQuery'. In Gemstone something like this works for me:
Gofer project load: 'PierAddOns2' group: #('Pier-Blog' 'Pier-Book' 'Pier-Design' 'Pier-Documents' 'Pier-EditorEnh' 'Pier-Google' 'Pier-JQuery' 'Pier-LinkChecker' 'Pier-Setup' 'Pier-TagCloud').
or something like:
ConfigurationOfPierAddOns2 project latestVersion load: #('Pier-Blog' 'Pier-Book' 'Pier-Design' 'Pier-Documents' 'Pier-EditorEnh' 'Pier-Google' 'Pier-JQuery' 'Pier-LinkChecker' 'Pier-Setup' 'Pier-TagCloud' 'Pier-Twitter').
or you can just use:
Gofer project load: 'PierAddOns2' group: 'ALL'.
ConfigurationOfPierAddOns2 project latestVersion load: 'ALL'.
