I tried validate(). It doesn't help. Actually it might be in the

I've put together a small example that uses two classes that shows the
problem I'm having. I'll include the classes below.

Actually they are. Right below the signature.

NetBeans doesn't do anything strange with the classes. I checked. they are a little bit more complex than necessary, but the added
complexity can be ignored for the most part.

Why the heck should we 'ignore' the unnecessary complexity? Why, instead,
do you not *remove* it so we never have to suffer the bandwidth, or take
(any) efforts to 'ignore' it ourselves! * If you actually need to post
code, please do us the courtesy of posting the *smallest* code example
that shows the problem.

If you had looked at the classes you would have found them to be quite
small, but complete. I added the warning more out of courtesy than out of

You really should look at the code before spinning off on these kinds of
tangents. Now we have two complete messages devoted to a few lines of
extra code in the classes.

I don't know what Andrew is using for a reader but in Thunderbird it is
almost impossible to read your code after the signature. That is a
TBird problem but...

Your program is not as simple as it really needs to be but here is one
issue I've found.

         JPanel panel = new ChoreHeaderPanel();

You are adding panel to jPanel1 but not to it's layout. Also I know
that the IDEs love GroupLayout but it is a pain to read and understand.
  Why is panel not added in initComponents()? I think part of your
problem is calling add() on jPanel1 and not addComponent() on its
layout. And since we are talking about IDEs does it add the variable
declarations at the end of the class file or is that author's choice?
