Dataprovider anotation - Testng Selenium Java

Question

Query - The last set of values keep failing, the error that i am getting is that its unable to fine the xpath, but its working fine for other two cases. So a bit confused. I have pasted the error code as well. Would appreciate any help I can get. Thanks in advance.

Test Code -

@Test(priority = 4, dataProvider = "getData")
            public void loginScenario(String Username, String Password) throws InterruptedException {

WebElement user =  driver.findElement(By.xpath(".//*[@id='LoginForm_username']"));
                 if(null != user) {
                     user.clear();
                 }

                 WebElement pass =  driver.findElement(By.xpath(".//*[@id='LoginForm_password']"));
                 if(null != pass) {
                     pass.clear();
                 } 

                // driver.findElement(By.xpath(".//*[@id='LoginForm_username']")).click();
                // driver.findElement(By.xpath(".//*[@id='LoginForm_username']")).click();
                driver.findElement(By.xpath(".//*[@id='LoginForm_username']")).sendKeys(Username);
                driver.findElement(By.xpath(".//*[@id='LoginForm_password']")).sendKeys(Password);
                driver.findElement(By.xpath(".//*[@id='login-form']/button")).click();
                driver.findElement(By.xpath(".//*[@id='LoginForm_username']")).clear();
                driver.findElement(By.xpath(".//*[@id='LoginForm_password']")).clear();

            }

            @DataProvider
            public Object[][] getData() {

                Object[][] data = new Object[3][2];
                data[0][0] = "abcd";
                data[0][1] = "xyz";
                data[1][0] = "...";
                data[1][1] = ".";
                data[2][0] = "[email protected]";
                data[2][1] = "kingkongkijai";

                return data;

            }
        }

Error -

I just added the below code after you inputs and you were bang on ! Thanks so much

WebElement user = driver.findElement(By.xpath(".//*[@id='LoginForm_username']"‌​)); if(null != user) { user.clear(); } WebElement pass = driver.findElement(By.xpath(".//*[@id='LoginForm_password']"‌​)); if(null != pass) { pass.clear(); }
