I created a Panel using Matisse. When I restarted the IDE and the form opened, I was greeted with NullPointerException shown below. This was with the 6.0 05/21 daily build. I downloaded the latest daily (05/29) and tried again. Same result. Following is the messages.log content, including the exception: >Log Session: Tuesday, May 30, 2006 10:32:16 AM EDT >System Info: Product Version = NetBeans IDE Dev (Build 200605292030) Operating System = Linux version 2.6.15-1.2054_FC5 running on i386 Java; VM; Vendor; Home = 1.5.0_06; Java HotSpot(TM) Client VM 1.5.0_06-b05; Sun Microsystems Inc.; /opt/java/jdk1.5.0_06/jre System Locale; Encoding = en_US (nb); UTF-8 Home Dir.; Current Dir. = /home/twolf; /home/twolf Installation; User Dir. = /opt/java/netbeans/nb6.0:/opt/java/netbeans/ide8:/opt/java/netbeans/enterprise4:/opt/java/netbeans/harness:/opt/java/netbeans/platform7; /home/twolf/.netbeans/dev Boot & Ext.

Created attachment 30672 [details] The java file that has the problem - will also attach .form file
Created attachment 30673 [details] The corresponding .form file
Created attachment 30822 [details] log message and defected source files
I'm a bit confused with the logs you've attached. The first one which you pasted here shows what happened when you tried to open the damaged form. But what is the second one supposed to be (contained in the attached zip file)? BTW don't you have by chance the log from the session when you designed the form? I.e. before you restarted and it failed to open? Thanks
Pavek(?), I didn't attach any logs: I initially pasted a log message and then I attached two files (the affected java file and the affected form file.) The other log file was attached by 'kima' - i don't know what that is about. As to your other question whether I still have the log from when I created the form, no, I don't. It's been about a month since I reported this - since then I've restarted the IDE about 20 times. NB only keeps the last 3 logs around. Out of curiosity, I tried opening the ProxySettingsPanel.java in Matisse in my latest build. I no longer get a NullPointerException....instead, I get java.lang.AssertionError in the IDE dialog and in the log file I see INFO [stderr]: Could not use the declared superclass: com.netforensics.desktop.components.NFPanel INFO [stderr]: java.lang.InstantiationException Does NB have trouble instantiating classes that were originally defined as standard JPanels and subsequently were changed to inherit from some user- defined class? Anyway, I don't know whether these errors have to do with this issue or whether one of my refactorings caused this problem (since the editor isn't exactly reliable in terms of what it saves and doesn't save these days :-( I will try to debug this in the afternoon. Will let you know if it relates to this issue. Sorry I couldn't be of more help. tom
Thomas, thanks for explanation. I've looked at your form (ProxySettingsPanel) and it contains two components of the same name (jCheckBox1) which is wrong. I already know how this can happen and am working on a fix. Perhaps it will also be possible to fix such errors automatically when you open such form. The form attached by kima is similar, but slightly different - there is invalid name of a component as well, but here it is "null". I'll also try to fix the form during opening automatically. However in this case I don't know exactly the cause (have not been able to create such form). Given that another such form is attached in issue 76749 it is apparent it can happen somehow...
Re: "Could not use the declared superclass: com.netforensics.desktop.components.NFPanel" This is a harmless message - it only means that form editor could not load this class (likely it is not compiled) or instantiate it (likely it is not a JavaBean) while opening a form that extends it (i.e. the class of the form has "extends NFPanel" clause). Form editor tries create the instance of the declared superclass and shown in the designer. If that fails, it prints the message and uses plain JPanel for visualization (which is mostly enough).
I've implemented a fix that automatically corrects invalid component reference. So now the forms form this issue (as well as others - e.g. issue 76749) should open without problems. I've also fixed one case when an invalid component name could occur - undoing copy/paste operation. /cvs/form/src/org/netbeans/modules/form/layoutdesign/LayoutComponent.java new revision: 1.14; previous revision: 1.13 /cvs/form/src/org/netbeans/modules/form/layoutdesign/LayoutModel.java new revision: 1.32; previous revision: 1.31 /cvs/form/src/org/netbeans/modules/form/layoutdesign/LayoutPersistenceManager.java new revision: 1.16; previous revision: 1.15 /cvs/form/src/org/netbeans/modules/form/CopySupport.java new revision: 1.29; previous revision: 1.28 /cvs/form/src/org/netbeans/modules/form/RADComponent.java new revision: 1.161; previous revision: 1.160 /cvs/form/src/org/netbeans/modules/form/MetaComponentCreator.java new revision: 1.92; previous revision: 1.91 /cvs/form/src/org/netbeans/modules/form/GandalfPersistenceManager.java new revision: 1.166; previous revision: 1.165 /cvs/form/src/org/netbeans/modules/form/FormModelEvent.java new revision: 1.27; previous revision: 1.26 /cvs/form/src/org/netbeans/modules/form/HandleLayer.java new revision: 1.149; previous revision: 1.148 /cvs/form/src/org/netbeans/modules/form/FormModel.java new revision: 1.70; previous revision: 1.69
