Hi,

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.


The DocumentListener


calls the berechne()



Do you have any solutions, to solve the problem.
