hello, I have problem to display error message from ajax request, here is my code :
<?php echo CHtml::ajaxButton ("Proses", CController::createUrl('tool/prosesTutupBukuCabang'),
                  array('type'=>"POST",
						 'update' => '#data_tutupBukuCabang',
                         'data'=> array('periodeBulan' => 'js:document.getElementById("periodeBulanCabang").value',
										'periodeTahun' => 'js:document.getElementById("periodeTahunCabang").value',),
						'success'=>'function(data){
							$("#data_tutupBukuCabang").empty();
							$("#data_tutupBukuCabang").append(data);
							$("#data_tutupBukuCabang").hide();
							$("#data_tutupBukuCabang").css({"background-color":"yellow","height":"20px","text-align":"center","line-height":"20px","color":"green"}); 
							$("#data_tutupBukuCabang").show( "slow" ).delay(3000);
							$("#data_tutupBukuCabang").hide(1000);
						}',
						'error'=>'function(data,status){
							alert(status.responseText);
						}',
									));?>
