Bug 26641 No option to disable "Assignment ... has no effect"
2.1 M3 I am missing an option to disable the compiler warning upon assigning a variable to itself...
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/CompilerConfigurationBlock.java
if (i > 0) {
				tags.append(',');
				prios.append(',');
			}
			TodoTask elem= (TodoTask) list.get(i);
			tags.append(elem.name);
			prios.append(elem.priority);
		}
		fWorkingValues.put(PREF_COMPILER_TASK_TAGS, tags.toString());
		fWorkingValues.put(PREF_COMPILER_TASK_PRIORITIES, prios.toString());
	}
		
	private void doTodoButtonPressed(int index) {
		TodoTask edited= null;
		if (index != 0) {
			edited= (TodoTask) fTodoTasksList.getSelectedElements().get(0);
		}
		
		CompilerTodoTaskInputDialog dialog= new CompilerTodoTaskInputDialog(getShell(), edited, fTodoTasksList.getElements());
		if (dialog.open() == CompilerTodoTaskInputDialog.OK) {
			if (edited != null) {
				fTodoTasksList.replaceElement(edited, dialog.getResult());
			} else {
				fTodoTasksList.addElement(dialog.getResult());
			}
		}
	}
	
}
