#FindBy error With class Select - selenium-webdriver

Question

I am trying to implement Page Object with annotation #FindBy in class Select. In Eclipse it's showing following a message:
the method id(String) in the type By is not applicable for the arguments (WebElement).
I do not why this message comes. Follow below the code and image of error.
Class FaturamentoGeTratamentoOsPage
public class FaturamentoGeTratamentoOsPage {
WebDriver driver;
#FindBy(id = "cboMotivo")
WebElement CBOMotivo;
public FaturamentoGeTratamentoOsPage(WebDriver driver) {
this.driver = driver;
}
public void preencherCampoMotivo(String CampoMotivo) {
// Campo Motivo
WebElement campoMotivo = driver.findElement(By.id(CBOMotivo));
Select slcMotivo = new Select(campoMotivo);
slcMotivo.selectByVisibleText(CampoMotivo);
}
public void preencherCampoSubmotivo(String CampoSubMotivo) throws Exception {
}
}
Class FaturamentoGeConectividadeFacilidadesTest
public class FaturamentoGeConectividadeFacilidadesTest {
static WebDriver driver;
#Before
public void setUp() throws Exception {
SelecionarNavegador nav = new SelecionarNavegador();
driver = nav.iniciarNavegador("chrome", "http://10.5.9.45/BkoMais_Selenium/");
}
#Test
public void selecionarFacilidades() throws Exception {
// Logando na aplicação
LogarBkoMaisPage login = new LogarBkoMaisPage(driver);
login.logar("844502", "Bcc201707");
// BackOffice >> FaturamentoGe >> Conectividade
FaturamentoGeConectividadeFacilidadesPage menu = new FaturamentoGeConectividadeFacilidadesPage(driver);
menu.logarFaturamentoGeConectividade();
//Registro >> Novo caso
RegistroNovoCasoPage reg = new RegistroNovoCasoPage(driver);
reg.registrarCaso();
//Preencher campos
FaturamentoGeTratamentoOsPage campo = new FaturamentoGeTratamentoOsPage(driver);
campo.preencherCampoMotivo(" Concluido ");
}
#After
public void tearDown() throws Exception {
Thread.sleep(5000);
driver.quit();
}
}

Answer 1

You need to add pagefactory.init to initialize webelement.
public FaturamentoGeTratamentoOsPage(WebDriver driver) { this.driver = driver;
PageFactory.initElements(driver, this);
}
No use of below line .. because CBOMotive directly returns you a webelement only
WebElement campoMotivo = driver.findElement(By.id(CBOMotivo));

Answer 2

You are getting the error because By.id() expects a String, not a WebElement. You have defined CBOMotivo as a WebElement but are treating it like a String.
The following is correct usage
WebElement campoMotivo = driver.findElement(By.id("cboMotivo"));
What you want is
public void preencherCampoMotivo(String CampoMotivo) {
// Campo Motivo
Select slcMotivo = new Select(CBOMotivo);
slcMotivo.selectByVisibleText(CampoMotivo);
}
