Hi, there is a bug in tutorial
"Extending The Visual Editor: Enabling support for a custom widget"
when I want to create editing behaviour of the text property there is
NullPointerException somewhere in EMF, because it doesn't find
somewhat(DELEGATE) of EMF EReference of the text property. Because of that
it will not show properties view.
HERE IS STACKTRACE OF EXCEPTION:
