✔ Text aus JTextArea auslesen

[lord_kleener]

Hi Leutz,
hab schon wieder mal ne Frage . Eigentlich sollte es doch total einfach sein, den Text aus eine JTextArea auszulesen (bei Event). Hier der Code:

public void insertUpdate(DocumentEvent e)
{
Elemente el = this.bg.list.FindElementbyData(e.getDocument());
String test = ((JTextArea)el.Data).getText();
System.out.println(test);
String msg = el.id + "TextChanged$";
System.out.println(msg);
//this.bg.ReadXml(msg);
}

Also ich hole mir das Objekt aus einer Liste (t). Danach will ich in test das Ergebnis haben -> 1000 Fehlermeldungen:
Exception in thread "AWT-EventQueue-1" java.lang.ClassCastException: javax.swing.text.PlainDocument cannot be cast to javax.swing.JTextArea

Checked das irgen jemand Das Event ist ein DocumentListener an einer JTextArea.
Importiert habe ich:

import java.awt.*;
import java.net.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.tree.*;
import java.io.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.parsers.*;
import javax.swing.event.*;

Kann mir jemand sagen, wo mein Fehler liegt, bittebitte

Okay, habs hinbekommen, ist zwar echt bescheuert zu realisieren in Java, aber egal!!
