Dear Geertjan, Sorry for the delay - urgent project took up too much time.
I'm not sure what you mean by a "Stack trace" - there's no dump available as it didn't crash. I've now put the example onto GitHub at https://github.com/ptoye/TestFormBug Here's as small an example as I can manage. Steps to reproduce: Open TestFormBug in NB 11.1 (I'm on Windows - don't know if the OS is relevant). If not already open, in package com.ptoye.testFormBug, open OuterPane.Java. Click on "Design" tab You should get an error message saying the file is corrupt. If you don't, your system is different from mine.

When I open the .java file in a text editor, the editor-fold lines have extra information // <editor-fold defaultstate="collapsed" desc="Generated Code">//GEN-BEGIN:initComponents and } // </editor-fold>//GEN-END:initComponents But these don't appear when I look at the file in NetBeans. I've done the same for a very simple project which I started from scratch and the same happens. Is the editor performing some sort of censorship on auto-generated comments? It doesn't make looking for problems any easier. Or is it a bug, in which case I'll report it? But I still can't develop my project until I can sort this. I'm attaching the error that I get in case it helps. Does anyone know exactly what the GUI editor is looking for, so that I can edit the file to satisfy it? Various attempts by me to try that have all failed. ------------------------- Tuesday, October 22, 2019, 11:55:09 AM, you wrote: Another issue moving from NB 8 to 11.1 I moved a Java with Ant project from NB version 8 to 11.1, and everything seemed fine until I decided to modify a form within the project. I got an error message saying that the GUI builder couldn't find the generated code. The message directed me to the wiki page http://wiki.netbeans.org/FormGuardedBlockError which describes the issue, but the generated code sections of my project seem OK - I reproduce them below. These are identical to code generated on a new project which of course doesn't give the error. // <editor-fold defaultstate="collapsed" desc="Generated Code"> private void initComponents() { ... add(pnlButtons, java.awt.BorderLayout.NORTH); ?? } // </editor-fold> // Variables declaration - do not modify private javax.swing.ButtonGroup bgColours; ... private javax.swing.JRadioButton rbtTemp; // End of variables declaration ?? Any ideas on how I can recover from this, as the code looks fine? Regards, Peter mailto:netbe...@ptoye.com www.ptoye.com
