Build Identifier: I20110620-1631 Created e4-RCP. Tried to open an dialog. Because of errors replaced it by JFace MessageDialog. Results in null-pointer-exceptions. traces by debugger to: ShellActivationListener (package org.eclipse.e4.ui.internal.workbench.swt) (org.eclipse.e4.ui.workbench.swt.source._0.10.0.v20110613-2030.jar) >> EContextService contextService = context.get(EContextService.class); contextService.activateContext(EBindingService.DIALOG_CONTEXT_ID); >> contextService is null. With an older Version (I20100922-0843) (jar file version 0.9.1.v20100909-1100) it works fine. Reproducible: Always Steps to Reproduce: 1. New Eclipse-download + E4 Tools + E4 UI from e4/updates/0.11 2. New OSGI-Project, product and aplication-model 3. Handler for dialog @Execute public void execute(@Named(IServiceConstants.ACTIVE_SHELL) Shell shell, IEclipseContext context) { MessageDialog.openQuestion(shell,"Dialog","Question?"); } 4. DirectMenuItem 5. MainWindow and menu shows; error, when selecting entry

Didn't understand the problem of bug 361877 completely but the problem with the dialogs I've reported has been solved with Remy Suens answer. Current Eclipse adds them by default if you don't deactivate the corresponding checkbox while creating a new application model -e4xmi- by wizard.
