Created attachment 100011 [details] screen shot I20080510-2000 1. Show synchronize view 2. Incoming mode 3. Show change sets 4. Synchronize workspace 5. Wait Is: After a while you get a couple of "change sets" called something like 'Error: no label provider blablabla'. See screen shot. Should: I don't know, certainly not that.
Wow, I've never seen anything like that before. Is it reproducible? Does the error log say anything interesting? Do the change sets stay like that?

The screen shot shows how it looks today. I guess the bug is that some incoming changes are not added to a change set by the view. > Does the error log say anything interesting? No > Do the change sets stay like that? To make them go away switch to outgoing mode and back.
Just came across this too. The funny this is that it does not seem to be an changeset. Invoking Plugin Spy shows that my regular changesets are instances of ContextChangeSet while these "no label provider" items are instances of "JavaProject" (at least that's what Plugin Spy says). Nothing in the logs for me too. Steps, see #0. The only little difference here is that the items are really big and contain besides the "no label provider.." many more lines with all java packages of these projects. Maybe it only looks like this for me as I'm on GTK while Benno is on Windows and for him the Item only shows the first line of text.

In windows, at least in my case, it was not possible to expand the items with the error label.
Thanks for your feedback guys, but I'm afraid this issue is caused to multi-threading involved in managing the Sync view and Change Sets in particular. Which makes it harder for me to solve since I'm working on a single core machine. I will try to switch to our dual core desktop as often as possible, and I will for any signs of the issue you reported. Until then, what I can suggest is to use workaround from Benno's comment 2. Marking as Assigned, even though I haven't reproduce it, I'm sure none of the provided screen shots is a fake ;)
Hi, i'm using eclipse I20080617-2000, and i got the same error today (with a non dual core machine). The steps are: * having 2 "named" CS = change sets in synchronize view * doing some java editing on other files * doing a synchronize from java perspective adds the <Unassigned> CS with 1 sub node saying Error: no label provider for MYJavaProject Don't know if it's important but i was in "Incoming/Outgoing mode".
I used to get this problem every once in a while but don't remember seeing it with Eclipse 3.5 or 3.6.
Created attachment 199799 [details] no label provider in egit This seams to be a navigator core bug, because it recently appears in EGit UI test cases. I can always reproduce it bu running all tests in SynchronizeViewGitChangeSetModelTest class. When I've run this test case in debug mode this bug doesn't occur, it seams to be a very strange race-condition.

I've just run the test and haven't spotted the fishy label. > Is there a wiki page describing what do I need and how to run these tests?

I can see the same problem on my machine. In my case, the "Error: no label provider..." element of the tree is also a JavaProject but not the one from JDT but from JSDT. JSDT uses this name for JavaScript project and that can be verified in the valid interfaces section of Plug-in Spy where it says it is an IJavaScriptProject. Comment 6 and comment 9 confirm what I saw while debugging this problem - it looks like a race condition while managing events used to populate data in the Sync view. It's very hard to find out what's causing this error label so marking as dependent on the bug that is about improving the error reporting in such cases.
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.
