isElementPresent failing mysteriously... logs attached #7541

Originally reported on Google Code with ID 7541

Hi y'all,

  I'm seeing strange behavior and a selenium server error with no error message with
a call to isElementPresent.  Can you help figure out what is going on here?   Thanks!
 As far as I can tell, I'm on the latest versions of selenium and Firefox.  

  Thanks a lot!

  Dave

---------------

What steps will reproduce the problem?

1. Run selenium test on page.  

CALLING CONTEXT (see below for code of Wait::forElementPresent)

        $this->selenium->click("link=Click here to try it.");
        Wait::forElementPresent("//a[text()='Click to log in.']", $this->selenium, 30000,
"'Click to log in' link was not found.");

What is the expected output? What do you see instead?

There is a wait loop which waits for an element "//a[text()='Click to log in.']" that
is generated in once the page script is done running, but, after the selenium server
error (SEE LOG BELOW) is encountered, selenium exits immediately.  In other words selenium
isn't waiting as it should be.

Can't reproduce with the attached page.

    DefaultSelenium selenium = new DefaultSelenium("localhost", 4444, "*firefox", "http://localhost/");
    selenium.start();
    try {
      selenium.open("http://localhost/install_courseinsite.html");
      selenium.isElementPresent("//a[text()='Click to log in.']");
      Thread.sleep(5000);
    } finally {
      selenium.stop();
    }
