As in bug #179016, perhaps triggered by an earlier exception:

java.lang.NullPointerException
	at org.netbeans.modules.form.VisualReplicator.updateContainerLayout(VisualReplicator.java:296)

Probably a Swing bug in there too. Best to use the latest JDK update (and maybe update NetBeans to 7.1.2 as well).

Perhaps one of the problems with SwingX components as described in bug 127881.
