tapestry-beanvalidation
We'd like to use JSR-303 bean validation and mark invalid fields in the UI.
The Tapestry beanvalidation module already does quite a good job but has a
minor bug when it comes to embedded objects. The problem is that component
parameters i.e. the TextField#value is only bound to the attribute itself
but doesn't contain the full objectpath, so using a DTO like:
class TestDTO {
@NotNull
private String firstName;
@Valid
private EmbeddedObject embeddedObject;
...
}
class EmbeddedObject {
@NotNull
private String lastName;
...
}
Using the TestDTO on a page in the following way:
class MyPage{
...
@Property
private TestDTO testDTO;
@Component(parameters = {"validate=testDTO"})
private Form form;
@Component(parameters = {"value=testDTO.firstName"})
private TextField firstName;
@Component(parameters = {"value=testDTO.embeddedObject.lastName"})
private TextField embeddedField;
...
}
Submitting the form validates all the attributes correctly (also the
embedded object validation error is listed in the t:errors component) but
when it comes to BeanFieldValidator only lastName is on the Environment
Stack in the BeanValidationContext. As TestDTO doesn't contain the property
lastName and there's no objectpath available it doesn't traverse down the
objects and can't assign the correct validation error.
