Bug on serverConstructor?

[edulid]

Following your advice here: http://forums.smartclient.com/showthread.php?t=26985

I started to write the logging classes but I think there is a smartGWT Bug.

Test case (adapted from the showcase)

WorldDSExport.xml

    <DataSource  
        ID="worldDSExport"  
        tableName="worldDS"  
        serverType="sql"  
        recordName="country"  
        serverConstructor="zedes2.server.SqlLoggingDataSource"

            <field name="pk"            type="sequence"    hidden="true"            primaryKey="true" />  
            <field name="countryCode"   type="text"                   required="true"   />  
            <field name="countryName"   type="text"                 required="true"   />

            </operationBinding>  
        </operationBindings>  
    </DataSource>

SQLLoggingDataSource.java:

public class SqlLoggingDataSource extends DataSource  {

    private static final long serialVersionUID = 1363865609764341340L;

    @Override
    public DSResponse executeAdd(DSRequest req) throws Exception {
        DSResponse response = super.executeAdd(req);
        log(req, response);
        return response;
    }
    
    
    public void log(DSRequest request, DSResponse response) {
	if (response.getAffectedRows()!=0) {
	    System.out.println("execute add");
	}
    }

}

Testing Module (EntryPoint):

public class TestingModule implements EntryPoint {

    public void onModuleLoad() {

	DataSource worldDSExport = DataSource.get("worldDSExport");

	final ListGrid countryList = new CountryList();
	countryList.setWidth(500);
	countryList.setAlternateRecordStyles(true);
	countryList.setDataSource(worldDSExport);
	countryList.setAutoFetchData(false);
	countryList.setShowFilterEditor(true);
	countryList.setFilterOnKeypress(true);
	countryList.setFetchDelay(500);

	ListGridField countryName = new ListGridField("countryName", "Country");
	ListGridField capital = new ListGridField("capital", "Capital");

	countryList.setFields(countryName, capital);
	countryList.setAutoFitData(Autofit.VERTICAL);
	countryList.setShowFilterEditor(true);
	countryList.setAutoFitMaxRecords(10);

	VLayout layout = new VLayout(15);
	layout.setAutoHeight();

	HLayout formLayout = new HLayout(15);
	layout.addMember(formLayout);

	layout.addMember(countryList);

	Criteria c = new Criteria();
	c.addCriteria("continent", "Europe");
	countryList.fetchData(c);

	layout.draw();
    }

    private class CountryList extends ListGrid implements
	    FilterEditorSubmitHandler {
	DSRequest properties;

	public CountryList() {
	    properties = new DSRequest();
	    properties.setOperationType(DSOperationType.FETCH);
	    addFilterEditorSubmitHandler(this);
	}

	@Override
	public void fetchData() {
	    super.fetchData(null, null, properties);
	}

	@Override
	public void onFilterEditorSubmit(FilterEditorSubmitEvent event) {
	    Criteria c = event.getCriteria();
	    System.out.println("Filter criteria: " + JSON.encode(c.getJsObj()));
	    fetchData();
	}

    }

=== 2013-06-27 19:10:40,737 [l0-0] INFO  Compression - /zedes2/sc/DataSourceLoader: 121324 -> 17428 bytes

As soon as I take away the serverConstructor="zedes2.server.SqlLoggingDataSource", no error occurs. But if I put the serverConstructor the error shown above occurs.

Using SmartGWT 3.1p EE 21-05-13.
But I also tried with the actual nightly (2013-06-26) and also with the 4.1d (2013-06-27) and still I get this error.

[Isomorphic]

Please double-check this result. It makes no sense at all, and there is probably actually some other different between the way you are testing with serverConstructor and without. Specifically, this error normally occurs if your deployment is missing war/sc/system/schema because you forgot to run a GWT compile.

[edulid]

I double checked the result, and it is the same:

if I delete the line

serverConstructor="zedes2.server.SqlLoggingDataSource"

everything works.
If I put it again, I get the error.

If I then delete it again, it again works. So I don't change anything else, only the line from worldDSExport.ds.xml.

The complete log is here:
