You should put parent around ?:. The '+' op is evaluated before "!=". Your
statement is effectively this:
("C:" + currentCustomer) != null ? currentCustomer.getFullName() :
"nocustomer"
So != null is always true and you get NPE on currentCustomer.getFullName()
Do this:
"C:" + (currentCustomer != null ? currentCustomer.getFullName() :
"nocustomer"));
then you are safe.
