无法识别使用Selenium RC和eclipse动态的下拉框

Question

这是HTML代码的一部分，描述了下面的下拉框。

<select id="f86_optReasonCodes" class="GTOptionMenu GTFillHorizontal optReasonCodes GTDisplay" onchange="this.changed=true;clientAPI.postEvent('f86_optReasonCodes',1);" onblur="looseFocus();" onfocus="gainFocus('f86_optReasonCodes');" size="1" name="f86_optReasonCodes" title="A list of outcomes to choose from" tabindex="10"></select>

<input id="f86_optReasonCodes_info" type="hidden" value="formID=86,objectID=2,componentType=5"></input>

id是动态的，因此我使用xpath来识别元素。我正在使用Thread方法减慢脚本。

Thread.sleep(10000);
//selenium.select("id=f95_optReasonCodes", "label=Complete Telephony");
selenium.select("XPath=//select[contains(@id, '_optReasonsCodes')]", "label=Complete Telephony");
selenium.click("css=option[value=\" Complete Telephony\"]");

我收到的错误消息如下。有人可以帮我这个吗？

com.thoughtworks.selenium.SeleniumException: ERROR: Element XPath=//select[contains(@id, '_optReasonsCodes')] not found
