[java] How to wait until an element is present in Selenium?

I'm trying to make Selenium wait for an element that is dynamically added to the DOM after page load. Tried this:

fluentWait.until(ExpectedConditions.presenceOfElement(By.id("elementId"));

In case it helps, here is fluentWait:

FluentWait fluentWait = new FluentWait<>(webDriver) {
    .withTimeout(30, TimeUnit.SECONDS)
    .pollingEvery(200, TimeUnit.MILLISECONDS);
}

But it throws a NoSuchElementException - looks like presenceOfElement expects the element to be there so this is flawed. This must be bread and butter to Selenium and don't want to reinvent the wheel... could anyone suggest an alternative, ideally without rolling my own Predicate?

Let me recommend you using Selenide library. It allows writing much more concise and readable tests. It can wait for presence of elements with much shorter syntax:

$("#elementId").shouldBe(visible);

Here is a sample project for testing Google search: https://github.com/selenide-examples/google

public WebElement fluientWaitforElement(WebElement element, int timoutSec, int pollingSec) {

    FluentWait<WebDriver> fWait = new FluentWait<WebDriver>(driver).withTimeout(timoutSec, TimeUnit.SECONDS)
        .pollingEvery(pollingSec, TimeUnit.SECONDS)
        .ignoring(NoSuchElementException.class, TimeoutException.class).ignoring(StaleElementReferenceException.class);

    for (int i = 0; i < 2; i++) {
        try {
            //fWait.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//*[@id='reportmanager-wrapper']/div[1]/div[2]/ul/li/span[3]/i[@data-original--title='We are processing through trillions of data events, this insight may take more than 15 minutes to complete.']")));
        fWait.until(ExpectedConditions.visibilityOf(element));
        fWait.until(ExpectedConditions.elementToBeClickable(element));
        } catch (Exception e) {

        System.out.println("Element Not found trying again - " + element.toString().substring(70));
        e.printStackTrace();

        }
    }

    return element;

    }

FluentWait throws a NoSuchElementException is case of the confusion

org.openqa.selenium.NoSuchElementException;     

with

java.util.NoSuchElementException

in

.ignoring(NoSuchElementException.class)

WebDriverWait wait = new WebDriverWait(driver,5)
wait.until(ExpectedConditions.visibilityOf(element));

you can use this as some time before loading whole page code gets executed and throws and error. time is in second
