Upon launch of eclipse, the workbench gets about a 1/4 of the way through it's initilization, then the IDE opens with the following error. No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab nothing else in the log file that I can find.
Please attach the log file it generates from <workspace>/.metadata/.log PW
Hi Jeff, have you installed the Aptana's plugin.

The key conflicts are just warnings, they won't effect your emptyEditorTab problem. Does anyone have stack trace that starts with the problem message? PW
Well, what I've posted was the Eclipse log from the start up without doing anything more, so no more logs messages were shown than those.
(In reply to comment #4) > Well, what I've posted was the Eclipse log from the start up without doing > anything more, so no more logs messages were shown than those. Sorry, if the error is not in the error log, where does it display? If you can't copy it, could you snap a screen-capture? PW
Created attachment 221327 [details] screenshot of error This screenshot was taken after encountering the bug described.
I encountered the same error upon launching Eclipse on Mac OS X 10.8.1. The log file doesn't appear to contain anything pertinent; just in case, I've included it below. I previously attached a screenshot of the error. (Apologies for attaching it out of order.) With reference to Eduardo's comment, I haven't installed Aptana.

Hi, I have got a similar problem: when I close Eclipse (Juno) and re-open it, many times (but not always, and totally randomly), it opens up almost correctly, but all the editors that were opened just show this famous "No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab", instead of the content of the file they (are still labelled to) refer to. And of course nothing in the logs. FYI, I use the emacs key bindings with CTRL-X CTRLC binded to Exit. I have noticed that when I use this key combination to quit Eclipse, I don't see any DialogBox show 'Saving Workspace' and the problem occurs almost every time, whereas when I use the menu entry File->Exit, I see the DialogBox and most of the time do not have any problem... In case this can help... GM
(In reply to comment #8) Hi. The next time it happens, could you please attach your .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi PW
I had the same issue. Closing eclipse and removing .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi solved it! As requested, I will attache the workbench.xmi, which raised the bug.

Any ideas here? The editor descriptor EMPTY_EDITOR_ID = "org.eclipse.ui.internal.emptyEditorTab" is created in the method addSystemEditors(HashMap map) {} in org.eclipse.ui.internal.registry.EditorRegistry. For what is this descriptor meant to be used to? When I get the mentioned error what did I do wrong implementing my own editor?
The error message appears in my case when I still have an instance of my editor open and I kill the Eclipse instance and restart Eclipse. I do not get it if I close the Eclipse instance normally. When I had a file opened with my editor Eclipse does not open the file in my editor anymore if I close Eclipse normally and restart Eclipse. For the standard Eclipse XML editor this works as expected. I think I implemented some part of the API not correctly for my file based editor so that I get the mentioned error message. The standard Eclipse editors never get the error message because they are implemented correctly? I still use Eclipse 3.x API for my editor.
Created attachment 236794 [details] The Eclipse workbench does not look good I'm seeing this too in Kepler Service Release 1 Build id: 20130919-0819 on Fedora 18 GRECLIPSE installed. How it happened: Accidentally try to open 40 Meg XML file in workspace (not versioned) This fails (abysmally long load, Eclipse hangs). Kill Eclipse. Restart. No error messages in log, but " No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab" Additionally, the workspace rendering is mangled. Apparently Eclipse still tries to open the .xml file... :-(
Created attachment 236795 [details] Dump details I forget to say that the above indeed showed "No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab", but I don't know where the message went. Anyway, "details" shows that there was an OutOfMemory exception (as expected and attached). Closing all the views, then restarting Eclipse gets it back on track.
I'm a developer on Aptana and we see this occasionally happening for users - though as developers we tend to run into this a lot. It'll happen if you have our "Dashboard" editor open (which is really just a web browser editor) and then the IDE crashes (or if you're developing under Eclipse like us, just kill the process abnormally, like say running in debug mode, changing code and then choosing to terminate when hot code swap dialog pops up). We'll end up with two "Dashboard" editor tabs on the next restart, one of which has this white area with the error label. (We auto-open a "Dashboard" on startup, so we should only every have one of these and it should be "good"). The relevant portion of the xmi file is: <children xsi:type="basic:Part" xmi:id="_HSQ1SkF4EeOD4qAZsT5jmA" elementId="org.eclipse.e4.ui.compatibility.editor" contributionURI="bundleclass://org.eclipse.ui.workbench/org.eclipse.ui.internal.e4.compatibility.CompatibilityEditor" label="Dashboard" iconURI="platform:/plugin/com.appcelerator.titanium.ui.override/icons/titanium_16.png" tooltip="Titanium Studio Dashboard" closeable="true"> <tags>Editor</tags> <tags>removeOnHide</tags> </children> The editor is a web browser editor and is not meant to be persistable (so ideally it wouldn't get recreated on restart). I can hack around this by running the following code in the UI during startup to clean up the busted editors: // If there are existing busted portal/dashboard tabs, remove them IWorkbenchPage activePage = workbenchWindow.getActivePage(); IEditorReference[] refs = activePage.getEditorReferences(); for (IEditorReference ref : refs) { String editorId = ref.getId(); if (EditorRegistry.EMPTY_EDITOR_ID.equals(editorId)) { activePage.closeEditors(new IEditorReference[] { ref }, false); } }
Hi, close all files and restart eclipse. I have been getting the similar error ( a little different) : No editor descriptor for id org.eclipse.vjet.ui.VjetJsEditor The problem was I had a js plugin installed in eclipse and my js file was associated with VJET editor. This is what the case seems to be here as well. you see this error once you installed the plugin. All you have to do is fix you file associations : preferences->General->Editors->file Associations. click on the file type you are seeing this error with and choose the appropriate editor. Now close all files and restart eclipse. this should work. Thanks, Vishal
Steps to reproduce in pure Eclipse SDK 4.6.0.I20160128-2000: - Preferences: Set "Workspace save interval" to 1 minute - paste to Package Explorer: package p; public class C { public static void main(String[] args) { System.out.println("Hi"); } } - select C.java in Package Explorer, and duplicate with Ctrl+C, Ctrl+V, Enter - select C.java and C2.java - context menu > Compare With > Each Other - wait for 1 minute (until workbench save interval has passed) - kill the Eclipse process => When you start the same workspace again, the compare editor tab is restored (icon and tab text), but the content is an error editor. Expected: Tabs for non-restorable editors should be closed after a crash (like on normal shutdown).

I'm running into this problem but when I close the error editor, Eclipse freezes and doesn't seem like it will come back. I was only able to fix the problem by killing and restarting Eclipse and then, as soon as it opened, pressing ctrl+shift+w to close all editors.
Hello, I had some similar problems when terminating the eclipse instance and restarting with empty editor tabs. I did some debugging through eclipse code and think I've found at least what's creating the error part. In WorkbenchPage.setup, it calls createEditorReferenceForPart with the editor id of "org.eclipse.e4.ui.compatibility.editor". Unfortunately, the id is not found in the registry and descriptor is set to null. The correct id of the editor page can be found in MPart part's tags but the code doesn't seem to be using that. Following in the EditorReference constructor, descriptorId is set to "org.eclipse.ui.internal.emptyEditorTab". Then later, when EditorReference.createPart is called, since descriptor is null, createErrorPart is called, using the descriptorId we had set earlier leading to the creation of the error page with the very confusing error message. Hopefully this helps if someone is looking into this problem. I'm having trouble finding the cause of this problem or a consistent way to reproduce it.
I hit the same problem after (re)starting Eclipse after Windows did a forced update of my machine. The restarted Compare Editor shows "No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab" and a similar stack trace. (It is possible that the Compare Editor had oreviously gone bad/stale as a result of regeneration of one of the compared files.)
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
Multiple users have reported the problem. Surely needs a relevant committer not a genie to WONTFIX?
