No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab ------------------------------------------------------------------ Key: JBIDE-17021 URL: https://issues.jboss.org/browse/JBIDE-17021 Project: Tools (JBoss Tools) Issue Type: Bug Components: central, upstream Reporter: Max Rydahl Andersen Assignee: Fred Bricon Fix For: 4.2.0.CR1 I keep from time to time to get two central editors to open up. 1) with "No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab" 2) a few seconds later the real Central. My guess is that the editorinput for central is not behaving properly so it does not know how to restore itself causing it to be empty on start and then we force opening a new one even though already one there.
