Hi!
I'm using MySQL 4.x.x, Hibernate 2.1 and Spring 1.0.1.
I'm developing a webapp that will be able to catch data concerning healthcare from many forms and users. A big part of data is entered
through checkboxes (multiple choices) and radiobuttons.
An Event holds a composite collection of EventFieldOptionNode objects. EFONode in its turn denotes 1:M-relations with both PageField
(object representing the field in HTML form) and FieldOption.
I've managed to get a HTML-form with options behave as expected, i.e I can add and delete options freely. But when I empty one field
completely (uncheck all options) I get this exception (with last piece of debug trace):

To add non XDoclet property mappings, create a file named

Does anybody recognize this exception..... EventFieldOptionNode has a standard argument (i.e 'void') getter for property field....
