MethodInvocationException class

The error a BeanWrapper throws when a property's setter itself threw, for example because it validates the value.

cause is what the setter threw. DataBinder records it as a methodInvocation field error.

// The iban setter rejects malformed values.
try {
  BeanWrapper(account).setPropertyValue('iban', 'nope');
} on MethodInvocationException catch (e) {
  log.warning(e.cause); // what the setter threw
}

Spring (Java):

} catch (MethodInvocationException e) { ... }
