When the following code replaces the toComponent() line in the original
code, this prevents the NPE:
ExtensionRegistry er = new ExtensionRegistry();
er.setErrorReporter(new ErrorReporterImpl());
fDescriptionElement.setExtensionRegistry(er);
fDescription = fDescriptionElement.toComponent();
I confess can't yet see the necessity for in architectural terms, so would
still like reassurance that this is by desgn?
Also, do you think is NPE is reasonable if the above code doesnt appear ?
Many thanks!
Kind Regards,
Graham.
