Description mna 2007-04-15 13:57:52 UTC 
I am getting a NullPointerException when I try to drag the border of the JFrame
with the mouse, in the attached test project.
NetBeans version is "NetBeans IDE 5.5 (Build 200612070100)" and Java version is
1.6.0_01.
To reproduce the issue: Simply open the attached test project as a new project
(after having uncompressed and untarred), open test.java (the only source file
in the project), and try to drag border of the JFrame in the Design tab. You
should see a blinking red sign on the right bottom of the IDE indicating the
exception occured.

Reassigning to form for evaluation
Comment 4 Tomas Pavek 2007-07-26 17:50:23 UTC 
The attached form contains one misconfigured component - jTabbedPane3 is missing constraints data for its position in 
split pane. Not sure how this could happen, but I've made a fix that is able to deal with it.
