Looks like the root cause is in the form designer:

Comment 3 Tomas Pavek 2014-11-19 13:46:41 UTC 
Looks like if the designed GUI form contains a JRadioButton with a null model.
Can you check it? There were several reports of this from older NetBeans releases. The null model on a button does not make sense, but could have been set by accident. If you have a GUI form on which the exception can be reproduced by opening in the designer, can you attach it here? Thanks.
