Description of problem:
The package of the class ValidateEventListener is misspelled. Instead of
"validator" you have "valitator" on two occasions (pre-insert, pre-insert).
Version-Release number of selected component (if applicable):
If you need to create a new listener you might want to copy-paste the default
values for pre-insert/pre-insert listeners and add your own classes. With the
current error you will introduce a bug in your code that will throw a runtime
exception on application startup.
The same problem exists on this page
Mass Re-Assignment to Vinu for vetting. Investigate and migrate to JIRA if
Done. Will be available in the next CP release (4.2 CP03 and 4.3 CP01)
