我是Flex新手，需要一些幫助來設置Web服務客戶端。Web服務動作錯誤
我有方法的Web服務：我在創建動作腳本調用這個服務面臨的問題
public String printEchoStr(String str);
。我得到錯誤：
1067: Implicit coercion of a value of type String to an unrelated type
generated.webservices:PrintEcho.
我不確定這是否是正確的方法。
謝謝，

您可以上傳生成的EchoService.as源代碼嗎？ – Sophistifunk 2010-06-01 04:55:51
我已經上傳了由Data-> Import WebService生成的EchoService的代碼 – 2010-06-01 12:52:58
我試圖發送一個參數在TextArea中打印webservice的響應。 – 2010-06-01 13:19:56
