A previous fix (change 146550) for gr-select surfaced another issue that
was previously masked by it. gr-select takes a bind-value but in cases
where that value is not supplied, the dropdown appears to be blank.
In order to have the correct default values, the objects being two way
bound have to get set to have the default value.
