I am pretty new to Java, Swing, and Netbeans.  I need help
understanding a problem, which I describe here.

I have class LMtextBlock extends javax.swing.JPanel and an instance of
that class, primaryTextBlock.  The textBlock is a component of

javax.swing.JScrollPane LMscrollPane;

In the textBlock I use my own layout manager. (This is essential.)

Whenever I open the Frame (which contains these) in Netbeans' Design
View, I get a message stating:

"Errors occured in loading the form data.  It is not recommended to use
. . ."

I can post this whole message if anyone requests, but it basically says
"There is a problem and we recommend you don't edit this thing until
you fix it."  When I then select "View Only" or "Allow editing," it
reveals another message saying:

"Error in loading component:
[JFrame]->LMscrollPane->primaryTextBlock
No layout support was found.
Layout information for this container cannot be loaded.

I guess my first question should be, am I interpreting the message
correctly?  Is it complaining because I am using a custom layout
manager?

(It should be noted that I did not go through Netbeans to add the
layout manager.  I could not see how to do that, so I add it
"manually.")

My other question is, is there anything I can do about this?  If I have
to add it through Netbeans interface, how do I make Netbeans aware of
my custom layout manager so I can add it the way it wants?  Or, if I
need to be asking a different question, please help me know what that
should be (and then what the answer is, of course.)

Thanks to anyone who responds.
