Hi,
I am starting a very basic e4 Application. The workbench model only
contains one TrimmedWindow and a Binding Context. The application starts
fine, but when I add the liveeditor to my launch config, I get an NPE on
start-up (see below). It seems that the EHandlerService is null. e4 core
service and commands are part of the launch config.
any ideas?
Cheers
Jonas
Affected Line:
EHandlerService hs = (EHandlerService)
context.get(EHandlerService.class.getName());
Exception:
java.lang.NullPointerException
