Grid as Field

Hi

in Vaadin 7.x I've implemented a view with Table binded to value as Field, using PropertysetItem:

PropertysetItem pItem = new PropertysetItem();
...
if (certParam != null) {
    certTable.setRequired(certParam.isRequired());
    pItem.addItemProperty("certTable", new CertListParameterProperty(certParam.getPaParam(), certs));
}
...
binder = new FieldGroup(pItem);
binder.bindMemberFields(this);

By this way I can get/set table selected rows automatically and tie it to model value.
But it doesn't work on Grid, I think because Grid is not an AbstractSelect. Maybe I can wrap grid with a class that implements CustomField<Grid>.

After read Vaadin 8 documentation, I think it would be the same.

There is any plan to reach such a feature?
It is usefull for my when I have to present a multi-selectable list of  values, and I need to present more than a single property of an row entity (more columns).

Thank you.
