How can I overcome Element id exception in Selenium?

Question

T set 'id' for GWT widgets in UiBinder itself.

For eg.

Also added in *.gwt.xml

Then I try this in Selenium test case

WebElement element = driver.findElement(By.id("gwt-debug-loginButton"));

Sometimes it works correctly. But some times it throws the following exception,

Unable to locate element: {"method":"id","selector":"gwt-debug-loginButton"} Command duration or timeout: 62 milliseconds

What i need to update? Can anyone help me?

Use WebDriverWait, to search for element after a certain period of time. Something like this.

try {
        (new WebDriverWait(driver, seconds, delay)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                try {
                    WebElement el = d.findElement(By.id("gwt-debug-loginButton"));
                    return true;
                } catch (Exception e) {
                    return false;
                }
            }
        });
    } catch (TimeoutException t) {
        //Element not found during the period of time
    }
