Hello, please try the singleSourceValidation sample modified as in this testcase:

 <DataSource isSampleDS="true"
    ID="supplyItem"
    serverType="sql"
    tableName="supplyItem"
    titleField="itemName"
    testFileName="/examples/shared/ds/test_data/supplyItem.data.xml"
    dbImportFileName="/examples/shared/ds/test_data/supplyItemLarge.data.xml"
>

    <fields>
        <field name="itemID" type="sequence" primaryKey="true"/>
        <field name="itemName" type="text" title="Item" length="128" required="true"/>
        <field name="SKU" type="text" title="SKU" length="10" required="true"/>
        <field name="description" type="text" title="Description" length="2000">
        <validators>
             <validator type="required">
                   <applyWhen fieldName="SKU" operator="isNull"/>
             </validator>
           </validators>
        </field>
        <field name="category" type="text" title="Category" length="128" required="true"
               foreignKey="supplyCategory.categoryName"/>
        <field name="units" type="enum" title="Units" length="5">
            <valueMap>
                <value>Roll</value>
                <value>Ea</value>
                <value>Pkt</value>
                <value>Set</value>
                <value>Tube</value>
                <value>Pad</value>
                <value>Ream</value>
                <value>Tin</value>
                <value>Bag</value>
                <value>Ctn</value>
                <value>Box</value>
            </valueMap>
        </field>
        <field name="unitCost" type="float" title="Unit Cost" required="true">
            <validators>
                <validator type="floatRange" min="0" errorMessage="Please enter a valid (positive) cost"/>
                <validator type="floatPrecision" precision="2" errorMessage="The maximum allowed precision is 2"/>
            </validators>
        </field>
        <field name="inStock" type="boolean" title="In Stock"/>
        <field name="nextShipment" type="date" title="Next Shipment"/>
    </fields>


</DataSource>

isc.ValuesManager.create({
    ID: "vm",
    dataSource: "supplyItem"
})

isc.DynamicForm.create({
    ID: "dynamicForm",
    valuesManager: "vm",
    fields:[
{name:"itemName"}
]
});

isc.IButton.create({
    ID: "saveButton",
    title: "Save",
    click: "vm.saveData()"
});


isc.IButton.create({
    ID: "clearErrorsButton",
    title: "Clear Errors",
    click: "dynamicForm.clearErrors(true)"
});

isc.IButton.create({
    ID: "disableValidationButton",
    autoFit: true,
    title: "Disable Validation",
    click: function () {
        dynamicForm.disableValidation = !dynamicForm.disableValidation;
        this.setTitle((dynamicForm.disableValidation ? "Enable" : "Disable")+" Validation");
    }
});

isc.HStack.create({
    ID: "buttons",
    height: 24,
    membersMargin: 10,
    members: [saveButton, clearErrorsButton, disableValidationButton]
});

isc.VLayout.create({
    membersMargin: 10,
    members: [dynamicForm, buttons]
});

vm.fetchData({SKU:90600})

If you run it and click 'Save', you won't see a request. In fact, vm.getErrors() will indicate that the description is required. However, the applyWhen condition isn't satisfied, so I didn't expect this. Is it a bug, or am I missing something?
