Getting Text from TextField in CodeName One for Java

I have designed the GUI elements and put everything together using CodeName One plugin for Netbeans 8.1. I am first working on my client information GUI that has textfields and a submit button. I'm looking to retrieve the textfield imputs via the submit button action event(I will use the first name textfield as an example:
#Override
protected void onAddRecordGUI_SubmitButtonAction(Component c, ActionEvent event) {
..I tried this
String Fname = findTxt_Firstn(c).getText();
..I also tried this
String FirstName = findTxt_Firstn.getText();
..I then tried this
String FirstName = Txt_Firstn.getText();
}
I get "error: cannot find symbol" with regards to the textfields name (It is correct and located on the same form the button is located)
Am I doing something very wrong here? I found two post on Stack, however, I tried the solutions above anyway.

Okay! I have solved my own questions and this might be applicable to anyone else who encounters this issue. The issue isn't the code, but it is naming textfields with an underscore "_". I renamed the field and was able to create a reference to it.
Thanks.

xpath in firebug works however sendkey is not sending value

I am trying to write a login code for hotmail. I asked this a few days ago on how to get the xpath, someone answered and gave me the correct xpath in his reply:
//*[#id='CredentialsInputPane']//div[3]//div[2]/div
His answer worked.
Today I tried to come up with my own xpath solution and in Firepath when I use the following syntax it highlights the user name field.
//div[contains(#class,'placeholder has-focus')][text()='Email, phone, or Skype name']
Question/problem: When I run the test, in UI it does not send the value user#msn.com, it clicks the Next button and I get error "Please enter a value".
What is wrong with my xpath syntax, even though it is highlighting the field? Why is it not sending the email id?
Code:
driver.get("https://login.live.com/login.srf?");
driver.findElement(By.xpath("//div[contains(#class,'placeholder')][text()='Email, phone, or Skype name']")).sendKeys("usertest81#msn.com");
driver.findElement(By.xpath("//input[contains(#id,'idSIButton9')]")).click();
Thanks in advance for your time and explanation.

You are trying to send value to a non-input field. This may be the reason. Try with the following-
driver.findElement(By.name("loginfmt")).sendKeys("usertest81#msn.com");

How to copy a text from java code in cygwin?

I need to get the value of selected item and to copy it from Java application in cygwin.
My problem is that I don't know how to copy a text from Java application in cygwin.
This is a portion of my code:
private void jComboBox1ActionPerformed(java.awt.event.ActionEvent evt) {
String cmmd = "moshell"+jComboBox1.getSelectedItem()
/*I need a help here :how to write this text (cmmd) in cygwin?*/
}
I'm debutant in programming. Can someone help me to resolve this problem. Thank you.

If I understand your question, the same way you write any text to the console,
// I need a help here :how to write this text (cmmd) in cygwin?
String cmmd = "moshell"+jComboBox1.getSelectedItem();
System.out.println(cmmd);

sendKeys.RETURN not working in FirefoxDriver

if I execute the following code in FireFoxDriver:
WebElement element = driver.findElements(By.id("some_id")); // element being a textbox
element.sendKeys("apple");
element.sendKeys(Keys.RETURN);
The sendKeys(Keys.RETURN) is not performing its desired function.
Actually what I am trying to do is Input a text in a dynamic text search box (like one in facebook search) and press enter. The input is working fine but not the enter key.
sendKeys("apple") works, even sendKeys(Keys.BACK_SPACE) works, but not Keys.RETURN.
Does anyone have ideas? Thanks guys!

Not exactly sure why this happens, but there are a couple alternate ways of doing this that may help:
If elements are in a form, and there is no javascript that runs on submit or something you can use .submit() on any form input element, such as inputs and textareas:
WebElement element = driver.findElements(By.id("some_id"));
element.sendKeys("apple");
element.submit()
You can send the newline character with your input:
WebElement element = driver.findElements(By.id("some_id"));
element.sendKeys("apple\n");
Provide send_keys a list:
WebElement element = driver.findElements(By.id("some_id"));
element.sendKeys("apple", Keys.ENTER);

Got the solution to the above problem. U just need to add, a delay.
This happens because the Java Class runs too fast, so if u have sent a call, and pressed enter/ tab, before the element arrives, the enter is pressed, that is why this doesn't work. Just add Thread.delay(1000); before your Keys.RETURN command. That will do.
Worked for me.

I tried sending \n and fiddled with various commands until I found someone explaining that "keyPress (target) 13" will send the return key.
So first I use type to enter the string I want ...
*
*<tr>
<td>type</td>
<td>id=status</td>
<td>This is my test string</td>
</tr>*
*
... and then send the Enter key to the same text input box
*
*<tr>
<td>keyPress</td>
<td>id=status</td>
<td>13</td>
</tr>*
