I get this every few clicks, especially as I change editors in Eclipse. Or run a JUnit test, etc.

This started happening today when I installed your Angular2 IDE - and I previously and still have the Palantir Typescript, which apparently uses your Typescript as I look at the installation plug-ins.

Obviously this is more than annoying - makes my Eclipse installation barely usable now. Any ideas - hopefully that doesn't involve a complete clean re-install?

@piotrtomiak I think it's a bug with MyEclipse?

I also have exactly the same issue and also attribute it to Angular 2 IDE. Any solution other than rollback?

[bruno-frascino]

I got the same problem, any solution so far? It seems I will have to re install Eclipse

@digable1, @skinny-jones, @faxik - this issue may happen if you uninstall Webclipse JSjet, which is using enhanced version of Angelo's Tern.java project. JSjet is part of Genuitec Angular IDE as well. Unfortunately due problems with Eclipse P2 (which manages plugins), some plugins are left after uninstallation. This error happens, because com.genuitec.eclipse.javascript.tern bundle is not present in your installation, but our patched version of tern.eclipse.ide.core is, but it shouldn't. We have mitigated one of such issues, but looks like we will need to do more to address it. I am sorry for your problems. At this point, the only thing I can suggest is clean reinstall of Eclipse, or manual removal of problematic java.tern bundles from {eclipse-installation}/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info - just remove all lines with tern in the name.

May I ask you why you've decided to uninstall Angular IDE?

Thanks @piotrtomiak for your great explanation!

If there are something to do in tern.java to fix your problem, don't hesitate to do a PR.

Thanks, but unfortunately that's just some P2 mess we need to figure out.
