Grid Selection: Gets lost when saving form in 'Server' ds, but not with 'local' ds

[RubenS]

In the following example I have two datasources, one is a client only 'Testdatasource' and one is a mysql datasource. When editing and saving a record in the form, the selection in the grid gets lost with the mysql datasource but not with the local datasource. I would love to see selection kept also for mysql datasources.

Tested on SmartClient Version: SC_SNAPSHOT-2010-12-14/PowerEdition Deployment (built 2010-12-14) with GWT 2.1.0 and firefox 3.6.13

Form and grid code:

package test.client;

import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.data.DataSource;
import com.smartgwt.client.widgets.IButton;
import com.smartgwt.client.widgets.events.ClickEvent;
import com.smartgwt.client.widgets.events.ClickHandler;
import com.smartgwt.client.widgets.form.DynamicForm;
import com.smartgwt.client.widgets.grid.ListGrid;
import com.smartgwt.client.widgets.grid.events.SelectionChangedHandler;
import com.smartgwt.client.widgets.grid.events.SelectionEvent;
import com.smartgwt.client.widgets.layout.HLayout;
import com.smartgwt.client.widgets.layout.VLayout;

public class SelectionTest implements EntryPoint {

	@Override
	public void onModuleLoad() {
		
		//First ds: will keep selection
		//DataSource dataSource = CustomerLocalDs.getInstance();
		
		//Second ds: will throw away selection
		DataSource dataSource = DataSource.get("Customer");
		
		final ListGrid listGrid = new ListGrid();
		listGrid.setWidth100();
		listGrid.setShowResizeBar(true);
		listGrid.setCanEdit(true);
		listGrid.setCanPickFields(true);
		listGrid.setDataSource(dataSource);
		listGrid.fetchData();

		final DynamicForm form = new DynamicForm();
		form.setDataSource(dataSource);
		listGrid.addSelectionChangedHandler(new SelectionChangedHandler() {
			@Override
			public void onSelectionChanged(SelectionEvent event) {
				form.editSelectedData(listGrid);
			}
		});

		IButton save = new IButton("Save");
		save.addClickHandler(new ClickHandler() {
			public void onClick(ClickEvent event) {
				form.saveData();
			}
		});

		IButton doNew = new IButton("New");
		doNew.addClickHandler(new ClickHandler() {
			public void onClick(ClickEvent event) {
				form.editNewRecord();
			}
		});
		
		VLayout layout = new VLayout();
		layout.addMember(listGrid);
		layout.addMember(form);
		HLayout hlayout = new HLayout();
		hlayout.addMember(save);
		hlayout.addMember(doNew);

		layout.addMember(hlayout);
		layout.setHeight100();
		layout.setWidth100();
		layout.draw();
	}

}

Client ds:

package test.client;

public class CustomerLocalDs extends DataSource {

    private static CustomerLocalDs instance = null;

    public static CustomerLocalDs getInstance() {
        if (instance == null) {
            instance = new CustomerLocalDs("customerLocalDs");
        }
        return instance;
    }

    public CustomerLocalDs(String id) {

        setID(id);
        DataSourceIntegerField pkField = new DataSourceIntegerField("cstm_pk");
        pkField.setHidden(true);
        pkField.setPrimaryKey(true);
        DataSourceTextField nameField = new DataSourceTextField("cstm_name", "Name", 128, true);

        setFields(pkField, nameField);
        setClientOnly(true);
        setTestData(CustomerData.getRecords());
    }
}

package test.client;

public class CustomerData {

    private static CustomerRecord[] records;

    public static CustomerRecord[] getRecords() {
        if (records == null) {
            records = getNewRecords();
        }
        return records;
    }

    public static CustomerRecord[] getNewRecords() {
        return new CustomerRecord[]{
                new CustomerRecord(1, "Glue Pelikan Roll-fix Permanent #950"),
               	new CustomerRecord(2, "Glue Pelikan Roll-fix Refill Permanent #955"),  
                new CustomerRecord(3, "Glue Pelikan Roll-fix Non Permanent #960"),
                new CustomerRecord(4, "Glue Pelikan Roll-fix Refill Non Permanent #965")
        };
    }
}

package test.client;

import com.smartgwt.client.widgets.grid.ListGridRecord;

import java.util.Date;

public class CustomerRecord extends ListGridRecord {

    public CustomerRecord() {
    }

    public CustomerRecord(int cstm_pk, String cstm_name ){
    	setCstm_pk(cstm_pk);
    	setCstm_name(cstm_name);    
    }

    /**
     * Set the itemID.
     *
     * @param itemID the itemID
     */
    public void setCstm_pk(int cstm_pk) {
        setAttribute("cstm_pk", cstm_pk);
    }

    /**
     * Return the itemID.
     *
     * @return the itemID
     */
    public int getCstm_pk() {
        return getAttributeAsInt("cstm_pk");
    }


    /**
     * Set the item.
     *
     * @param item the item
     */
    public void setCstm_name(String cstm_name) {
        setAttribute("cstm_name", cstm_name);
    }

    /**
     * Return the item.
     *
     * @return the item
     */
    public String getCstm_name() {
        return getAttribute("cstm_name");
    }

}

Server ds:

<DataSource 
	serverType="sql"
	dbName="Mysql"
	tableName="Customer"
	ID="Customer"
>
	<fields>
		<field primaryKey="true" type="sequence" name="cstm_pk" hidden="true"></field>
		<field type="text" length="45" name="cstm_name" title="" required="true" export="true"></field>
	</fields>
</DataSource>
