Re: TreeSet in GWT RPC ?

[mjfan80]

I have a similar problem

In my project it seams that i can't use treeset

i get this error: [ERROR] Type 'org.teepee.gui.client.DataTablePatch'
was not serializable and has no concrete serializable subtypes

DataTablePatch, the class i want to send via rpc, is:

import java.util.TreeSet;

public class DataTablePatch implements
com.google.gwt.user.client.rpc.IsSerializable{

    private TreeSet<DataRow> rowsSet = new TreeSet<DataRow>();

    public TreeSet<DataRow> getRowsSet() {
        return rowsSet;
    }

    public void add(DataRow row) {
        System.out.println("AddRow DataTable patch, sto aggiungendo la
riga con id " + row.getId());
        this.rowsSet.add(row);
    }
}


DataRow class is

public class DataRow implements Comparable,
com.google.gwt.user.client.rpc.IsSerializable {
    private byte status;
    private List<ValueWrapper> data = new ArrayList<ValueWrapper>();
    private int id; //l'id sarà univo, sempre lo stesso in tutta la
sessione, sarà l'indice dell'array in cui la row sarà salvata

    public DataRow(){}

    public DataRow(List<ValueWrapper> values) {
        this.data = values;
    }

    public DataRow(DataRow dr) {
        this.data = dr.getData();
        this.id = dr.getId();
        this.status = dr.status;
    }

    public boolean equals(Object o) {
        if (o instanceof DataRow) {
            DataRow dt = (DataRow) o;
            return (this.id == dt.getId());
        } else return false;
    }

    public int compareTo(Object o) {
        DataRow dt = (DataRow) o;
        int id1 = this.getId();
        int id2 = dt.getId();
        if (id1 < id2) return -1;
        if (id1 == id2) return 0;
        else return 1;
    }

    public void deleteData() {
