Hello @karthikeyanvijayabalan

First of all, the TokenList component is bound with Datasources or Containers, it doesn’t work directly with database.

Let’s look at an example:

<!-- Screen layout -->
<data>
    <instance id="orderDc"
              class="com.haulmont.sampler.entity.Order"
              view="order-edit">
        <loader/>
        <collection id="orderItemsDc"
                    property="items"/>
    </instance>
    <collection id="allItemsDc"
                class="com.haulmont.sampler.entity.OrderItem"
                view="orderItem-with-product">
        <loader id="orderItemsLoader">
            <query>
                <![CDATA[select e from sampler$OrderItem e]]>
            </query>
        </loader>
    </collection>
</data>
<layout>
    <tokenList id="linesList"
	       dataContainer="orderDc"
	       property="items"
	       width="320px">
        <lookup optionsContainer="allItemsDc"/>
    </tokenList>
</layout>

So we can get a value like this:

// Screen controller

@Inject
private TokenList<OrderItem> linesList;

private void foo() {
    // list of items contained in "orderDc" container returned
    List<OrderItem> items = linesList.getValue();
}
