Hi Smalltalkers, I am new to this list. Just downloadad and started Pharo Seaside-3.1-OneClick under Linux in order to get my hands on jquery mobile development. As the documentations suggest I first performed: Gofer it url: 'http://ss3.gemstone.com/ss/jQueryMobile'; package: 'ConfigurationOfJQueryMobile'; load. ConfigurationOfJQueryMobile loadBleedingEdge. Now when I direct my browser to "http://localhost:8080/javascript/jquery-mobile/" it displays the error: "MessageNotUnderstood: WADefaultScriptGenerator>>close:on:pageId:" I was curious and modified JQMHtmlRoot>>closeOn: in the debugger like this: closeOn: aDocument "aDocument scriptGenerator >> I did comment this 2 lines close: self on: aDocument pageId: self pageId." self writeFootOn: aDocument and it works, I can browse thru the JQMobile examples now. However, I guess this is not really the way to go. Comments or advices anybody? Juergen
