Flex Datagrid가 업데이트되지 않습니다

Question

질문 : 각 구성 요소가 들어있는 3 개의 색인이있는 아코디언이 있습니다. 그 구성 요소는 항상 동일한 것입니다 (일반 datagrid). 이 DataGrid는 PHP와 JSON을 통해 데이터를받습니다.

내 Accordion의 SelectedIndex가 변경되면 내 DataGrid의 데이터가 변경되어야합니다. 내가 아코디언 - 인덱스를 변경할 때마다 $typeId 지금 selectedIndex의

if(isset($_POST['accIndex'])){ 
    $typeId = mysql_real_escape_string($_POST['accIndex']); 
} else { 
    $typeId = 1; 
} 

에게 있습니다

$query = "SELECT * FROM gerecht where typeID = " . $typeId; 

는, 데이터가 동일하게 유지 :

이

는 PHP는 쿼리입니다. 여기 내 플렉스 코드 : 뭔가를 추측하고있어

이 잘못된 것 중 하나에 : - selectedIndex의 수신 PHP는? - 또는 flex가 새 데이터로 DataGrid를 업데이트 할 수 없습니까?

Answer 1

K 마지막으로 해결책을 찾았습니다. 나는 2 개의 httpServices를 사용하고 있었고, 처음부터 데이터를 수신했지만,이 매개 변수를 포함하지 않았다. 그래서 저는 그것들을 하나로 합쳤습니다. 다음 코드에서 결과 : (다른 모든 구성 요소도 추가 했으므로주의하지 마십시오.)
