{
						result.addAll( getReferencedDimLevel( binding.getExpression( ),
								bindings, onlyFromDirectReferenceExpr ) );
					}
				}
			}
		}
		populateDimLevels( n.getFirstChild( ), result, bindings, onlyFromDirectReferenceExpr );
		populateDimLevels( n.getLastChild( ), result, bindings, onlyFromDirectReferenceExpr );
	}
	
	/**
	 * Get binding
	 * 
	 * @param bindings
	 * @param bindingName
	 * @return
	 * @throws DataException

	private static IBinding getBinding( List bindings, String bindingName ) throws DataException
	{
		for( int i = 0; i < bindings.size( ); i++ )
		{
			if ( ((IBinding)bindings.get( i )).getBindingName( ).equals( bindingName ))
				return (IBinding)bindings.get( i );
