Data Binding

You can bind a component to an entity and its attributes hold in a data container.

To bind numberField to an entity attribute:

  1. Specify the name of the data container as the dataContainer attribute value.

  2. Specify the name of the entity attribute as the property attribute value.

The entity attribute must be of Double, Integer or BigDecimal type.

    <instance class="" id="stepDc">
        <fetchPlan extends="_base"/>
        <loader id="stepDl"/>
    <numberField dataContainer="stepDc" property="factor"
                 step="0.5" stepButtonsVisible="true"/>
