Component Configuration at design time : how to get and display the input schema

hi All,

I'm posting here a new question around this topic because the other one is very old.

I'm trying to create a component and get the structure of the schema coming in in the "Component Tab", in design time, with Studio v8.

very basic layout with only one item :

Have you been able to implement this ? any idea what I'm missing ? thank you for your help.

package com.konvertilo.talend.components.processor;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import com.konvertilo.talend.components.dataset.CustomDataset;
import lombok.Data;
import org.talend.sdk.component.api.configuration.Option;
import org.talend.sdk.component.api.configuration.ui.layout.GridLayout;
import org.talend.sdk.component.api.meta.Documentation;
import org.talend.sdk.component.api.configuration.ui.widget.Structure;
import org.talend.sdk.component.api.record.Record;

@Data
@GridLayout({ @GridLayout.Row({ "dataset" }),
        @GridLayout.Row({ "incomingSchema" }) })
public class KRankProcessorConfiguration implements Serializable {

    @Option
    @Documentation("My dataset.")
    private CustomDataset dataset;

    @Option
    @Documentation("My Schema.")
    @Structure(type = Structure.Type.IN)
    private List<SchemaInfo> incomingSchema = new ArrayList<>();

    @Data
    @GridLayout({ @GridLayout.Row({ "label", "key", "talendType", "nullable", "pattern" }) })
    @Documentation("Schema definition.")
    public static class SchemaInfo implements Serializable {

        @Option
        @Documentation("Column name.")
        private String label;

        @Option
        @Documentation("Is it a Key column.")
        private boolean key;

        @Option
        @Documentation("Talend type such as id_String.")
        private String talendType;

        @Option
        @Documentation("Is it a Nullable column.")
        private boolean nullable;

        @Option
        @Documentation("Pattern used for datetime processing.")
        private String pattern = "yyyy-MM-dd HH:mm";
    }
}
