Problem Document Listener "Attempt to mutate in notification"
posted 8 years ago
i have following Problem. I have a couple of jTextField's that are registered to a DocumentListener.
I had the problem that i got always the Exception
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Attempt to mutate in notification at javax.swing.text.AbstractDocument.writeLock(AbstractDocument.java:1343) at javax.swing.text.AbstractDocument.replace(AbstractDocument.java:662) at javax.swing.text.JTextComponent.setText(JTextComponent.java:1441)
Then i was reading a little bit and found a solution, but this solution causes another problem, a endless loop and i get this
I want to call a method "calculate" with just some normal calculation from jTextField values.
