Weird behaviour of getText() ...!!!! PLEASE TAKE A LOOK!!

Question

Hi.
my problem is that i have two forms named JF_ChangeAP and DisplayTree. Suppose that JF_ChangeAP has two string variables named XMLFile and ElementDesired... I try to set the value of these two variables from the form DisplayTree(after i've created an JF_ChangeAP object,of course)... Take a look at the following code :
CODE THAT WORKS:
ShowAncestorsFrm.XMLFile=this.txtFilePath.getText();
ShowAncestorsFrm.ElementDesired="Logistics_person";
CODE THAT DOESN'T WORK:
ShowAncestorsFrm.XMLFile=this.txtFilePath.getText();
ShowAncestorsFrm.ElementDesired=this.txtElementDesired.getText();
(ALTHOUGH I TYPE Logistics_person in the TextField!!!!!)
I am going crazy...!!!!!!!!!!!!!!!!!!!!!!
When i debug the value of the ElementDesired in the JF_ChangeAP object is Logistics_person!!!! But it does not work! ! ! ! ! ! ! ! ! ! .......WHY??!?!?!?!?!?!?
Thnx in advance Guys.!

Answer 1

your code convetion is arkward..it's hard to tell what is a class and what is an object. you should try not to declar your variable public
MyClass.myVariable = ""; is not a good idea..and not object oriented (you broke encapsulation)
since your listing is vague and confussing, i can't really hel you debug your problem. although i'm thinking it's a reference problem..check to make sure you have pass in the correct reference..etc.
also make sure you created the textfield correctly..
for example:
public class Form1 extends JFrame{
    private JTextField textField = new JTextField(10);
    public Form1(){
        JTextField textField = new JTextField(20); 
        // this is wrong..your textfield declared above is not the same one
        // as you add to the frame..so when you call this.textfield.getText(),
        // you are geting the text from the textfield of the instance..not this    
        // local one (which will be displaying in the Frame)
       this.getContentPane.add(textfield);
}check to make sure the reference to the objects are correct.
you should redesign your application: here is an example
public void Form1{
    private JTextField txtFilePath = null;
    private JTextField txtElementDesired = null;
    public Form1(){
        final Form2 = new Form2();
        txtPath = new JTextField();
        txtElementDesired = new JTextField(10);
        JPanel panel1 = new JPanel();
        panel1.add(txtFilePath);
        panel1.add(txtElementDesired);
        JButton = new JButton("Submit");
        button.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e){
                form2.setFilePath(txtFilePath.getText());
                form2.setElementDesired(txtElementDesired.getText());
        JPanel panel2 = new JPanel();
        panel2.add(button);
        this.getContentPane.add(panel1, "Center");
        this.getContentPane.add(panel2, "Center");
    public String getFilePath(){ return txtFilePath.getText(); }
    public String getElementDesired(){ return txtElementDesired.getText(); }
public class Form2{
    private String elementDesired = null;
    private String filePath = null;
    public void setFilePath(String filePath){
        this.filePath = filePath;
    public void setElementDesired(String elementDesired){
        this.elementDesired = elementDesired;
}
