stacktrace
I can imagine how this issue is annoying. Unfortunately, I am not able to reproduce this issue and the attached stack- trace is not sufficient to track this problem down. It would be great to have a reproducible test-case. It would be ideal to have the problematic form (both .java and .form files) and exact steps that lead to the described problem. |
Build: NetBeans IDE Dev (Build nbms-and-javadoc-3856-on-090902) VM: Java HotSpot(TM) Client VM, 16.0-b03, Java(TM) SE Runtime Environment, 1.7.0-ea-b59 OS: Windows Vista, 6.0, x86 User Comments: alied: after saving JDialog Form GUEST: Changing the variable Name of a JMenuBar inside NetBeans GUI Editor GUEST: Changing the variable name of a Panel in the NetBeans GUI Editor GUEST: This is the second time in a row I have encountered this problem (I restarted NetBeans between occurrences). Here is more detail: 1. My project contained a second JFrame, with a JPanel inside of that, and several labels, text boxes and buttons inside of that. 2. I decided that instead of the 2nd JFrame, what I really needed was a modal dialog, so I created a JDialog component. 3. I renamed the JDialog component's variable name to something more sensible for my application. 4. In the design view, I dragged the components from the old JFrame into my new JDialog one by one using the component tree control in the middle left of the screen (default configs) 5. I switched to Source view to switch some references in code from the JFrame to the JDialog. 6. I tried to save by pressing ctrl-S. No luck. 7. I tried to save by pressing the save button. Still no luck. 8. I tried to save ty closing the source file, hoping to take advantage of the "do you want to save?" dialog. At this point I not GUEST: replacing a JFrame with a JDialog, and fixing references to the old component. my control key had stopped working in netbeans slightly before this crash.
