Bug Description

Binary package hint: netbeans

Package: netbeans 6.7.1
System: Ubuntu 9.10 production release, x86-32
Java: java-6-sun

I installed NetBeans and opened a project. Then I right-clicked on its main source package and tried to add a JPanel form. I saw the wizard, gave the form a name, and clicked OK. The wizard should create a file with the code of an empty JPanel. Instead, it greyed all the buttons and just sat there looking pretty. I used the Force Quit applet to kill it, downloaded NetBeans from the official site (a .sh file), and installed it. Did the same thing, and it worked like it's supposed to.

I can't reproduce your problem exactly. IDE creates a file with code of an empty JPanel. But an exception [1] is thrown.
As far as I understand the reason of the exception is an absence of "form.j2ee" module in the stripped ide configuration: lines 66-80 in "./swingapp/src/org/netbeans/modules/swingapp/resources/layer.xml" file [2].
Marek, what is your opinion? is such situation critical? Can we fix it somehow?
