Click works Intermittently

I have this strange issue. The purpose of the test is to login and click an element. The login test seems to work consistently but clicking an element after login seems to work intermittently. If I run the test 10 times, it seem to work 4 times.
 
driver.get("SomeWebsite");
              driver.manage().window().maximize();
              driver.manage().timeouts().pageLoadTimeout(1, TimeUnit.MINUTES);
              driver.findElement(By.xpath("//li[2]/a")).click();
              driver.manage().timeouts().pageLoadTimeout(100, TimeUnit.SECONDS);
              driver.findElement(By.cssSelector("input[id*='textfield']")).sendKeys("someemail");
              driver.findElement(By.cssSelector("input[type*='password']")).sendKeys("password");
              driver.findElement(By.xpath("//div[3]/em/button")).click();
             
             
The codes seem to work fine upto here. However, the below code is the one I am having the issue.
 
 
 
WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.presenceOfElementLocated(By.id("header")));
             
 
driver.findElement(By.xpath("//li/a")).click(); 
 
Testnging does not detect that the element was not clicked and does not report any failures. 
             

This looks like synchronisation issue. Webdriver is trying to find an elemnt before it loads. Better you can try writing customized ocde for wait,

Code:

public
static WebElement waitForElementPresent(final
By by,
int
timeOutInSeconds) throws UnsupportedEncodingException
{
WebElement
element;
try{
driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS); //nullify
implicitlyWait()WebDriverWait
wait =
new
WebDriverWait(driver, timeOutInSeconds);
element = wait.until(ExpectedConditions.presenceOfElementLocated(by));resetImplicitWait(12);
//reset
implicitlyWait
return element; //return the
element
}

catch (Exception
e)
{

writer.Exception(e.getMessage());
}

return
null;
}
