"Derived valueMap is therefore unpredictable" warning with SelectItem.

[stonebranch3]

Isomorphic,

I'm seeing the following warning logged for a SelectItem if it uses an option DataSource and the DataSource contains a record where the value field (animalId) is 0.

10:02:51.846:TMR3:WARN:fetchMissingValues:isc_SelectItem_1[Animal]:Deriving valueMap for 'animalId' from dataSource based on displayField 'animalName'. This dataSource contains more than one record with animalId set to 0 with differing animalName values. Derived valueMap is therefore unpredictable.

I'm using SmartClient Version: SNAPSHOT_v10.1d_2015-10-20/Pro Deployment (built 2015-10-20).

I did notice that if I change animalId from an integer field to a text field in the AnimalXmlDS, the warning is not logged.

Entry Point:

    public void onModuleLoad() {
        final DynamicForm form = new DynamicForm();
        form.setWidth(500);

        SelectItem animal = new SelectItem("Animal");
        animal.setOptionDataSource(AnimalXmlDS.getInstance());
        animal.setValueField("animalId");
        animal.setDisplayField("animalName");

        form.setItems(animal);
        form.draw();
    }

AnimalXmlDS.java:

public class AnimalXmlDS extends DataSource {

    private static AnimalXmlDS instance = null;

    public static AnimalXmlDS getInstance() {
        if (instance == null) {
            instance = new AnimalXmlDS("animalDS");
        }
        return instance;
    }

    public AnimalXmlDS(String id) {

        setID(id);
        setRecordXPath("/List/animal");
        DataSourceIntegerField animalIdField = new DataSourceIntegerField("animalId");
        animalIdField.setHidden(true);
        animalIdField.setPrimaryKey(true);

        DataSourceTextField animalNameField = new DataSourceTextField("animalName");

        setFields(animalIdField, animalNameField);

        setDataURL("ds/test_data/animal.data.xml");
        setClientOnly(true);
    }
}

animal.data.xml:

    <List>
        <animal>
            <animalId>0</animalId>
            <animalName>Cat</animalName>
        </animal>
        <animal>
            <animalId>1</animalId>
            <animalName>Dog</animalName>
        </animal>
        <animal>
            <animalId>2</animalId>
            <animalName>Giraffe</animalName>
        </animal>
        <animal>
            <animalId>3</animalId>
            <animalName>Goat</animalName>
        </animal>
        <animal>
            <animalId>4</animalId>
            <animalName>Marmoset</animalName>
        </animal>
        <animal>
            <animalId>5</animalId>
            <animalName>Mouse</animalName>
        </animal>
    </List>

Thanks.

Hi Isomorphic,

is this the same one as this?

Best regards

We're not sure what you mean. That other issue was solved before you reported this one, so it does not seem that they could be related.

I am no longer seeing this warning using SmartClient Version: SNAPSHOT_v10.1d_2015-10-25/Pro Deployment (built 2015-10-25).

Thanks!

Hi, Isomorphic
can be this fix ported also to the 5.0 branch?
