Bug 81733 RefactoringWizardDialog - ErrorPage - action buttons "Next Problem", "Previous Problem" do not work correctly
If a refactoring (checkFinalConditions method) finishes with a refactoring status, that has several entries with different severities, the following situation can happen: Action buttons "Next Problem", "Previous Problem" do not work correctly. (For example the button "Previous" does nothing.) Explanation: There is a bug. The list of entries is retrieved from a RefactoringStatus object and put into a RefactoringStatusViewer. The viewer sorts the items, using RefactoringStatusSorter. The implementation of RefactoringStatusViewer.revealElement(boolean) is wrong, because this takes the index from the table: int index= fTableViewer.getTable().getSelectionIndex(); but this index refers to an index in the sorted list and the code: if (doIt) fTableViewer.setSelection(new StructuredSelection(entries[index])); refers the index (increased or decreased) to the original list of entries (unsorted). The result is a mess after clicking on Next or Previous button.

public int compare(Viewer viewer, Object e1, Object e2) {
			int r1= ((RefactoringStatusEntry)e1).getSeverity();
			int r2= ((RefactoringStatusEntry)e2).getSeverity();
			if (r1 < r2)
				return 1;
			if (r2 < r1)
				return -1;
			return 0;
		}
