(... more)
So your "CoreListener" class calls VOUpdate.parseFactAndUpdateVO(),
which calls VOUpdate.parseAndUpdateDesignElement(), which, at line
1391, calls stringValue() on a Value object of type RU.FACT. The
stringValue() method throws this exception to tell you that a FACT
isn't a STRING. You'll have to look at parseAndUpdateDesignElement()
to see what it's doing exactly, but it's assuming something will be a
String, and it isn't. You can use Value.type() to check the type of a
Value before calling one of the xxxValue() methods.
