Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.

A DESCRIPTION OF THE PROBLEM :
I use three JTextPane with an hierarchically structure.
JTextPane 1 contains JTextPane 2 and JTextPane 2 contains JTextPane3 (or an
other JComponent with the same result).

Now if I set the cursor (by mouse navigation) in the JTextPane2 directly behind the JTextPane3 component and make an input, I'll get an exception (java.lang.ArrayIndexOutOfBoundsException: No such child: 0) and the input does not appear. If the JTextPane2 has lost the focus, the input appears.

If I set text at the same position by calling insertString(...) bovore the components are showed, no exception occures. If I set text in the same way after the components are showed, the excepton occures.

The exception generally occures only when a character is set at the first position after JTextPane2. Setting characters behind works.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and start the demo.

Set the cursor after the green JTextPane 3 and type any character.
You can see the exception thrown. Let the component loose the focus, you
can see the character you typed.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The typed character should be occure and no exception.

ACTUAL -
The exception and not the typed character.
