i've written eclipse rcp application runs fine in eclipse, however, packaging standalone application has been tricky. i've worked way though few class path errors, i'm getting new one. after running export wizard , launching application, throws classdeferror , classnotfoundexception, it's looking org.eclipse.ui.plugin.abstractuiplugin. did not find in copy of eclipse sdk, , downloaded sdk again sure, , still couldn't find it. found jar online supposedly contained fiel along other eclipse packages, however, got this: nosuchmethoderror: org.eclipse.ui.plugin.abstractuiplugin: method ()v not found i figure problem more did wrong rather class missing, i've gone though configurations , i'm sure required packages , dependencies included. ideas? download , install new version of adt plugin 21.0.0.

this going sound rather naive, i'm developing web application spans multiple pages. of these pages instantiate same class object w/ methods accesses cms using api. currently, when user starts creating content, i'm storing variables folder id content located in session variable. my question this: can instantiate single instance of class can used across pages without having on every page? if so, each person accessing page given own version of class? assume using static variables , methods isn't way go since shared in memory. , also, where/how declared if going used globally in web application in .net c# application? i recommend making base class inherits system.page. have page code behind inherit that. then, inside base class, create property reference object. example, this: public class basepage : system.web.ui.page { public foo currentfoo { { return (foo)session["foosessionob...

does longlistselector support data virtualization? read on several blogs does, can't work. here tried: provided ilist implementation itemssource list. problem list calls getenumerator() instead of this[int index] list item. so question: how implement data virtualization longlistselector ? as said, longlistselector still based around getenumerator when rendering ilist types. control need rewritten support purpose. while blogs might support it, none of them says how, i'm not inclined believe them. longlistselector's default render items. as loading of data, can done progressive using observablecollection. got example project shows how use observablecollection in combination longlistselector. basically allow progressively add more groups and/or, more data groups, , ui should update accordingly.
