You need to call ignoring with exception to ignore while the WebDriver will wait.
FluentWait<WebDriver> fluentWait = new FluentWait<>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(200, TimeUnit.MILLISECONDS)
.ignoring(NoSuchElementException.class);
See the documentation of FluentWait for more info. But beware that this condition is already implemented in ExpectedConditions so you should use
WebElement element = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.elementToBeClickable(By.id("someid")));
*Update for newer versions of Selenium:
withTimeout(long, TimeUnit) has become withTimeout(Duration)
pollingEvery(long, TimeUnit) has become pollingEvery(Duration)
So the code will look as such:
FluentWait<WebDriver> fluentWait = new FluentWait<>(driver)
.withTimeout(Duration.ofSeconds(30)
.pollingEvery(Duration.ofMillis(200)
.ignoring(NoSuchElementException.class);
