Hi, I am developing a web app using General Interface web toolkit. It makes heavy use of selectSingleNode and selectNodes. I am on Firefox 3.5.1 on Ubuntu 10.04 64 bit. There is another guy on the general interface forum with the same problem as me on Ubuntu 10.04 and Firefox 3.6.10. But a commiter on general interface on Kubuntu 10.04 and Firefox 3.6.13 does NOT get this problem. Below is my exception, running in -safe-mode with everything turned off. As an aside, I have Firefox to update to the latest 3.6, but it always remains on 3.5.1, no idea why. onError:Error { message:"objXML.selectSingleNode is not a function", fileName:"http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/xml/CDF.js", lineNumber:614, stack:"("")@http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/xml/CDF.js:614 ("",2)@http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/package.js:1268 ([object Object])@http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/package.js:1073 ([object Object])@http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/package.js:740 ([object Object])@http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/util/EventDispatcher.js:165 ("UserImpl",[object Array])@http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/app/Cache.js:322 ([object Array],null)@http://localhost:8081/secm/TibcoGI/JSX/js/jsx3/package.js:244 ("23","0",[object Array])@http://localhost:8081/secm/dwr/engine.js:654 ("\n//#DWR-INSERT\n//#DWR-REPLY\ndwr.engine.remote.handleCallback(\"23\",\"0\",[{email:null,firstName:\"Super\",id:1,lastLogin:null,loginName:\"admin7\",password:\"t*****\",phone:null,salutation:null,surname:\"User\",userEnd:null,userRole:[{id:1,name:\"admin\"}],userStart:null},{email:\"\",firstName:\"\",id:2,lastLogin:null,loginName:\"d*****\",password:\"9*****\",phone:\"\",salutation:\"\",surname:\"\",userEnd:null,userRole:[{id:1,name:\"admin\"}],userStart:new Date(1236038400000)}]);\n")@http://localhost:8081/secm/dwr/engine.js:548 ("\n//#DWR-INSERT\n//#DWR-REPLY\ndwr.engine.remote.handleCallback(\"23\",\"0\",[{email:null,firstName:\"Super\",id:1,lastLogin:null,loginName:\"admin7\",password:\"t*****\",phone:null,salutation:null,surname:\"User\",userEnd:null,userRole:[{id:1,name:\"admin\"}],userStart:null},{email:\"\",firstName:\"\",id:2,lastLogin:null,loginName:\"d*****\",password:\"9*****\",phone:\"\",salutation:\"\",surname:\"\",userEnd:null,userRole:[{id:1,name:\"admin\"}],userStart:new Date(1236038400000)}]);\n")@http://localhost:8081/secm/dwr/engine.js:545 ([object Object])@http://localhost:8081/secm/dwr/engine.js:1355 ([object Event])@http://localhost:8081/secm/dwr/engine.js:1205 ", name:"TypeError" } objXML is a wrapped Document. See the code here http://www.generalinterface.org/fisheye/browse/GI/trunk/gi/JSX/js/jsx3/xml/Document.js#r813 Any ideas on why this is happening and how to prevent it?
