-----------------------------------------
Summary: Windows group throws NPE on close for not persistable top
component
Key: NETBEANS-1049
URL: https://issues.apache.org/jira/browse/NETBEANS-1049
Project: NetBeans
Issue Type: Bug
Components: platform - Window System
Reporter: Svatopluk Dedic
Assignee: Svatopluk Dedic
I admit it is somewhat a corner case, but – I have a TopComponent whose
*getPersistenceType* returns *PERSISTENCE_NEVER* and so a corresponding config
file is never created on config fs. If the user closes the document group which
contains such an editor, the core throws a NPE:
