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:

Do you have any errors in the .log file in your workspace's .metadata
directory?

Here is my current .log file capturing that error's stacktrace.
Now I am using JAVA 1.4.2 but result (stacktrace and behaviour) is the same
like with java 1.5.0.
Scenario is that when I click on the MyCustomPrompter(from tutorial) than
an exception below is thrown and the eclipse's properties view will be
empty.

Try this first:
1) Open the VE, get the error, close the VE, but leave Eclipse running
2) Do Project->Clean...->Clean ALL (all is very important).
3) Try the VE again. If you still get the error, please send us the
class in question so we can see if there is anything in there that could
cause this.
