Yura Zhishko commented on JBIDE-5460:
-------------------------------------

The problem is in jsfnature in .project configuration file. Second project doesn't content jsfnature in .project file, but org.jboss.tools.jsf.jsfnature was safed for a first project in project model. It seems that project model was not fully reloaded after "Refresh" bacause project.getNature("org.jboss.tools.jsf.jsfnature") return JSFNature object and not null, this method is used in BundleMap class. But project.hasNature(String id) verify .project file for existing natures, EclipseResourceUtil.getModelNature(project) use this method. refreshRegisteredBundles should be skipped if a project doesn't have jsfnatures:

public void refreshRegisteredBundles() {
		if (!hasJsfProjectNatureType()
				|| !(editor.getEditorInput() instanceof IFileEditorInput)) {
			return;
		}
		IProject project = ((IFileEditorInput) editor.getEditorInput())
				.getFile().getProject();
