Bug 64372 Projects showing up in Package Explorer twice [package explorer]
20040527-0800 When I load the platform-ui module and org.eclipse.tests from HEAD org.eclipse.tests is showing up twice in the PackageExplorer. This is not a a problem in the Resource Navigator. Open type only shows it once so it doesn't look like there are two instance in the workspace
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/packageview/PackageExplorerPart.java
if (editor != null) {
				editorActivated(editor);
			}
		}
	}
	/**
	 * Returns the name for the given element.
	 * Used as the name for the current frame.

	String getFrameName(Object element) {
		if (element instanceof IJavaElement) {
			return ((IJavaElement) element).getElementName();

		}
	}
	
	void projectStateChanged(Object root) {
		Control ctrl= fViewer.getControl();

			fViewer.refresh(root, true);
