title: Selenium Element Not found even if Selenium populates the id
body: <p>I am using Selenium IDE Firefox plugin to create some test cases.  I click the Record button to record the steps.  When I am done, I stop the recording and would run the test cases to see how things go.  In this one particular element in an HTML table, Selenium identifies as <code>id=my_id_1</code> in the recording process; when I run the test case, it would say that Element <code>id=my_id_1</code> not found.  </p>
  
  <p>How can it be not found when the ID is detected within Selenium IDE?  How can I get around this problem?  I have tried using <code>//tr[4]/td[3]/a</code> too.  Using this approach (and using ID as well), when I click the Find button in the IDE, the corresponding item on the web page would be highlighted in yellow.  However, the test case would fail saying that the element cannot find found.  </p>
  
  <p>Thanks in advance,
  Monte</p>
