validateValue incorrectly reports java.lang.IllegalArgumentException: Invalid property
path. There is no property listOfString in entity simple_bv_servlet.Person
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: BVAL-175
URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-175
Project: Bean Validation
Issue Type: Bug
Affects Versions: 4.0.0.Alpha2
Environment: HEAD of JSR-303 RI
Reporter: Ed Burns
Calling validator.validateValue() seems to fail when it shouldn't.
Consider this pojo:
8<----------------------------------
package simple_bv_servlet;
import java.util.List;
import javax.validation.constraints.NotNull;
public class Person {
@NotNull
private String firstName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
@NotNull
private String lastName;
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
private List<String> listOfString;
public List<String> getListOfString() {
return listOfString;
}
public void setListOfString(List<String> listOfString) {
this.listOfString = listOfString;
}
}
8<----------------------------
And consider this selvlet which validates this pojo in its doGet() impl.

out.print("</p>");
}

violations = beanValidator.validate(person);

curViolation.getMessage() +

}
}
8<------------------------
The call to
Set<ConstraintViolation<Person>> violations =
beanValidator.validateValue(Person.class, "listOfString",
value);
causes this exception to be thrown:
java.lang.IllegalArgumentException: Invalid property path. There is no property
listOfString in entity simple_bv_servlet.Person
But I say, doch, there is such a property on the Person.
This is new behavior in 4.0.0.Beta2, and it's breaking Glassfish.
Thanks,
Ed
