Hi,

Thanks a lot Kay and Kunal. In fact, my proper tab Spiral2 Properties returned null. I’ve modified the code. Everything is ok now.

Best regards,

Charles-Henry

I’m using the 4.2 CS-Studio sources and I try to build the Spiral2 operation version. I execute my version in RCP e4 compatibility mode and use a application model (xmi file). I still face problems. When I try to create a Logbook entry with popup menu or action button. 

 

The error java.lang.NullPointerException at org.csstudio.logbook.ui.LogEntryWidget.updateUI(LogEntryWidget.java:1088)

is in code that tries to call updateUI() on one of the tabFolders of the logbook dialog:

 

 

Those tabs include the one for file attachments, a property tree, and one can add custom tabs. Did you add some custom tabs to the logbook dialog? Are you using the OLog, or some site-specific logbook?
