I am currently developing a small application for my exams next month. I am using the visual editor of Netbeans.
Suddenly it stopped working, giving me the exception at the end of the thread.
It appears it has something to do with my Tabbed Pane containing a panel called StuderendePanel.
Is anyone familiar with this issue, and how can I fix it?

We have now solved the problem.
We had our GUI to pass our controller object to our Studerende panel. However, when Netbeans calls the initComponents method of the GUI, the controller was not initialized, and therefore didn't work.

I have looked through similar questions on here, but none have helped. The stack trace doesn't help me fix the problem as it seemingly runs fine when not debugging. I have no idea how to fix it so it works with debugging, like it does with "Run".
Other questions similar to this one I have looked at, and they do not help me fix the problem.

The version of Report designer and bi server should be same. try that and post the result.
The error says the file already exists. You must either delete the file beforehand or check the "overwrite" checkbox.
I am trying to attach a jar library toolkit to one of my netbeans projects. However, when I go to File > Project Properties > Libraries > Add Wrapped Jar the import succeeds but running the plugin causes a NullPointerException. I suspect this has something to do with the path but I don't understand how to manipulate the path or why there is even a null pointer.

I am trying to delete a project in a swing based application, using " DefaultProjectOperations.performDefaultDeleteOperation"
But i keep getting this error.
The only stacktrace i have is the following one, but right now i am clueless as what could i be doing wrong, or even if this could be a netbeans defect.
I am using Netbeans 7.4 IDE. I cannot upgrade to v.8.0 as using this IDE it is a client specification.
Any help would be greatly appreciated.

According to the DefaultProjectOperations documentation, the exception is thrown because ProjectOperations.isDeleteOperationSupported returns false. According to the documentation for that method, false is returned because the project does not implement the interface DeleteOperationImplementation.
As far as I can tell, you need to implement that interface to delete the project.
Since going to 1.7.0_45 (and 51) my program sometimes hangs. All of it's windows work OK except for one, it's fairly complex and has around 60 JButtons, JTextFields, two JScrollbars, JLabels etc. But so do all my other windows and they work fine.
I've put debug lines to the console so I can see where the program is hanging and it seems to be during the repaint() fn. It's hanging at the line
Graphics g = getGraphics();
It has managed to draw some stuff to the screen so it's not the first call to repaint that's the issue. Looks like this: http://www.unixnerd.demon.co.uk/hungjava.jpg
I get this StackTrace. None of the lines of code are in my program. It only happens maybe one time in ten if I open and close the window. Never had the issue with Java 1.6.x. Happens on a few PCs (all Windows 7), not just mine.
Grateful for any ideas.
