There must have been a change in Struts 2.1.2.
Here is an update to the after() method that uses the ActionContext session
map:
protected void after(ActionInvocation invocation, ValidationAware
validationAware)
throws Exception
{
Result result = invocation.getResult();
if (result instanceof ServletRedirectResult
|| result instanceof ServletActionRedirectResult)
{
Map session = invocation.getInvocationContext().getSession();
Collection actionErrors = validationAware.getActionErrors();
if (actionErrors != null && actionErrors.size() > 0)
{
session.put(ACTION_ERRORS_KEY, actionErrors);
}
Collection actionMessages = validationAware.getActionMessages();
if (actionMessages != null && actionMessages.size() > 0)
{
session.put(ACTION_MESSAGES_KEY, actionMessages);
}
Map fieldErrors = validationAware.getFieldErrors();
if (fieldErrors != null && fieldErrors.size() > 0)
{
session.put(FIELD_ERRORS_KEY, fieldErrors);
}
}
}
The full interceptor source can be found here:
