The problem was in thread management. I was trying to execute the login instructions in the same thread that the main FX view runs. I figured it out using the Platform.isFxApplicationThread(); It returns true if the calling thread is the JavaFX Application Thread.
To fix my problem i just needed to create a new thread to run all my login instructions as you can see in bellow example:
public void initManager(final LoginManager loginManager) {
btnEntrar.setOnAction(new EventHandler<ActionEvent>() {
boolean mainThread = Platform.isFxApplicationThread();
System.out.println("This is the main Thread: " + mainThread);
Platform.runLater(new Runnable() {
@Override
public void run() {
progressInd.setVisible(true);
}
});
new Thread() {
public void run() {
boolean mainThread = Platform.isFxApplicationThread();
System.out.println("This is the main Thread: " + mainThread);
String email = loginTxtField.getText().trim();
String token = tokenTxtField.getText().trim();
if (email.equals("")) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", "Digite o e-mail");
}
});
return;
}
try {
Future future = loginProcess(email, token);
// showLoginLoading(future);
future.get();
if (!loginGatewayFailed && !loginTargetAppFailed) {
Login loginTargetApp = new Login(email, null, null);
loginManager.autheticated(loginTargetApp, loginGateway, gateway, file);
} else {
if (loginTargetAppFailed) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", loginTargetAppFailedCause);
}
});
} else {
if (loginGatewayFailed) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", loginGatewayFailedCause);
}
});
}
}
}
} catch (final Exception ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, ex.getMessage());
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", ex.getMessage());
}
});
}
}
}.start();
});
}
