问题 I have got ditched in a problem with Menu Contribution and PersistedState. I had no problem before removing the -clearPersistedState flag from the VM args. Now, the app has a weird behaviour, the menu contribution starts to pile up a menu entry every time the code is executed. Here it's the guilty snippet enclosed in a Processor: MDirectMenuItem menuItem = MMenuFactory.INSTANCE.createDirectMenuItem(); menuItem.setLabel("Another Exit"); menuItem.setContributionURI("bundleclass://" + "com

问题 It doesn't seem E4 is usable for a productive environment yet, but the compatibility layer has many bugs as well. Can I mix both in one application, to choose the one with less bugs for each use case? I assume that's not possible, because the plugin.xml has to look like this: <extension id="product" point="org.eclipse.core.runtime.products"> <product name="Application" <!-- this application ID is used for E3 applications --> application="org.acme.application" <!-- this application ID is used

问题 Using Eclipse RCP 3.x, it is possible to create a custom AbstractStatusHandler to intercept platform exceptions. One way to do this, is to override the getWorkbenchErrorHandler() method in the ApplicationWorkbenchAdvisor class like this: @Override public synchronized AbstractStatusHandler getWorkbenchErrorHandler() { if (m_errorHandler == null) { m_errorHandler = new MyWorkbenchErrorHandler(this); } return m_errorHandler; } After doing a lot of research in Eclipse forums, stackoverflow and in
