안녕하세요. 최근 Flash Builder 4.5로 작업하기 시작 했으므로 모바일 응용 프로그램을 빌드하는 동안 특히 내 응용 프로그램을 백 엔드 서버에 연결할 때 많은 어리석은 문제가 있습니다.PHP 및 MySQL을 사용하여 flex 4.5 DataGrid 채우기
현재 작업중인 것은 DataGrid를 업데이트해야하며이 데이터는 MySQL 데이터베이스에서 검색됩니다.
이 코드는 브라우저에 데이터를 명확하게 표시하지만 데이터 그리드는 업데이트되지 않습니다. 대신 다음과 같은 오류가 발생합니다.
TypeError: Error #1034: Type Coercion failed: cannot convert mx.utils::[email protected] to mx.collections.IList.

누군가 나를 통해 이것을 안내 할 수 있습니까? 여기에 편집
는 PHP 코드 :
<?php
// -----------------------------------------------------------------------------
// Initialization of the sql server
// -----------------------------------------------------------------------------
// hostname or ip of server (for local testing, localhost should work)
$dbServer='localhost';
// username and password to log onto db server
$dbUser='root';
$dbPass='password';
// name of database
$dbName='test';
mysql_connect("$dbServer", "$dbUser", "$dbPass") or die(mysql_error());
mysql_select_db("$dbName") or die(mysql_error());
//Creating the table and inserting the values in it...
mysql_query("CREATE TABLE IF NOT EXISTS mariah_transaction_log(
id INT NOT NULL AUTO_INCREMENT,
PRIMARY KEY(id),
date DATE,
details VARCHAR(150),
debit DOUBLE,
credit DOUBLE,
balance DOUBLE)")
or die(mysql_error());
mysql_query("INSERT INTO mariah_transaction_log
(date, details, debit, credit, balance) VALUES('2011-08-08','Zellers','12.56','0.00','12343.54') ")
or die(mysql_error());
$username = $_GET["username"];
// $namedGreeting = mysql_query("SELECT * FROM customer_list WHERE username='$username'") or die(mysql_error());
// $row = mysql_fetch_array($namedGreeting);
// echo "Hello ".$row['name']."!";
$Query = "SELECT * from mariah_transaction_log";
$Result = mysql_query($Query);
$Return = "<users>";
while ($User = mysql_fetch_object($Result))
{
$Return .= "<user><date>".$User->date."</date><details>".
$User->details."</details><debit>".
$User->debit."</debit><credit>".
$User->credit."</credit><balance>".
$User->balance."</balance></user>";
}
$Return .= "</users>";
mysql_free_result($Result);
print ($Return)
?>

오류가 Flex에서 발생하므로 MXML/ActionScript 코드를 질문에 포함해야합니다. –
@ LarsBlåsjö 미안하지만 완전히 내 마음을 스킵! 이제 MXML 구성 요소를 추가했습니다 ... – BurninatorDor
