Code:

            //setup localization setting
            WebElement we = selenium.findElement(By.cssSelector("a[id='workflowqueryrefresh']"));
            s_log.info(we.getText());
            s_log.info(we.getTagName());
            s_log.info("doing click");
            we.click();
            s_log.info("click is done");

Output from log:

[INFO ][main][] 07/22/2011 15:24:33 - main.TestCase1058SearchForEventByStatus - Refresh Workflow Query
[INFO ][main][] 07/22/2011 15:24:33 - main.TestCase1058SearchForEventByStatus - a
[INFO ][main][] 07/22/2011 15:24:33 - main.TestCase1058SearchForEventByStatus - doing click
[INFO ][main][] 07/22/2011 15:24:34 - main.TestCase1058SearchForEventByStatus - click is done

While the log says it is doing the click, nothing actually happens in the browser.

Using selenium 2.0.0 jar (standalone) and firefox 5.
Code works ok in ie 8.
