I have multiple sub-editor of the same data-model.
I will use Person as example

class Person {

    // May be null if the person is newly-created
    private String id;

    public String getName();
    public String getId();
}

EditorA implements Editor<Person> {

@Path("")
EditorB getEditorB(); -- of Editor<Person>, has ValueBoxEditorDecorator + TextBox of @Path("id")

@Path("")
EditorC getEditorC(); -- of Editor<Person>, has ValueBoxEditorDecorator + TextBox of @Path("name")

}

For testing, we will driver.flush(); where name is null.
Then driver.setConstraintValidator(Set<ConstraintValidator<?>> _person_bean_validator);

This will result the ValueBoxEditorDecorator  having 3 lines of EditorError message.
"""
Persons aren't just characters
Persons aren't just characters
Persons aren't just characters
"""

EditorA implements Editor<Person> {
@Path(".")
EditorB getEditorB();

@Path(".")
EditorC getEditorC();

}

This will result the ValueBoxEditorDecorator having 2 lines of of EditorError message.
"""
Persons aren't just characters
Persons aren't just characters
"""

EditorA implements Editor<Person> {
@Path(".")
EditorB getEditorB();

@Path("..")
EditorC getEditorC();

}

This will result the ValueBoxEditorDecorator having 1 line of of EditorError message.
"""
Persons aren't just characters
"""

Is this a correct behavior? 
It just doesn't seems right to me.

Am I understanding something wrong?

Part of this (at least) is expected behavior: https://github.com/gwtproject/gwt/issues/7399 but there might be bugs too (see my last comment on that issue)
