Lukasz Lenart commented on WW-4600:
-----------------------------------
It isn't possible, those lines just update a {{Map}} and there is check if the
{{Map}} isn't {{null}}, see the code snippet below:
{code:java}
Map<String, Object> session = invocation.getInvocationContext().getSession();
if (session == null) {
LOG.debug("Could not store action [{}] error/messages into session, because
session hasn't been opened yet.", action);
return;
}
LOG.debug("Store action [{}] error/messages into session.", action);
ValidationAware validationAwareAction = (ValidationAware) action;
session.put(actionErrorsSessionKey, validationAwareAction.getActionErrors());
session.put(actionMessagesSessionKey,
validationAwareAction.getActionMessages());
session.put(fieldErrorsSessionKey, validationAwareAction.getFieldErrors());
{code}
