Firstly, the error is in the line List list = null; You need to initialise the list to something. You are calling list.add(... in the following line.
I use the following method:
private List AddViolation(String path, String message)
{
Violation violation = new Violation();
violation.setPath(path);
violation.setMessage(message);
List list = getForm().getViolations();
if(list == null)
list = new ArrayList();
list.add(0, violation);
return list;
}And then add the violation by calling the method:
getForm().addViolations(AddViolation("/card", "New Error"));
Hope this helps!
