DirectFieldAccessor should support collections [SPR-12206]

[spring-projects-issues]

Artyom Dmitriev opened SPR-12206 and commented

I encountered the issue while trying to use DirectFieldAccessor along with JSR-303 Validation. Say, we have class Bar:

public class Bar {
    @NotNull
    private String value;
}

This code would work fine:

public class Foo {
    @Valid
    @NotNull
    private Bar bar;
}

whereas the code below would not work and I would get " java.lang.IllegalStateException: JSR-303 validated property 'bars[0].value' does not have a corresponding accessor for Spring data binding...":

public class Foo {
    @Valid
    @NotNull
    private List<Bar> bars;
}
