Indicate if the state uses the Fail follow-up transition type.
When set to true the state editor will display the Fail dropdown UI control listing all the possible states to chose from.
When returning true, the processing method(s) should have at least one condition that returns
continueFail()
.
Typically, states with database or external web service calls should support the
continueFail()
to handle all the errors from these calls.
